What Is Your Vertical boiler?

The vertical boiler can also be called a vertical steam generator, and the outer pot is “standing”, so it is called a vertical boiler. Conversely, if the shape is “lying down”, it is a horizontal boiler.

Most of the vertical boiler design is for some small boiler products. You can use it in residents, offices, or to meet small production.

Vertical boilers are very different from the boilers on the general steam locomotive, while this kind of boiler is usually horizontal and not vertical.

Nowadays our modern design of the vertical boiler has long been separated from the steam locomotive, alone into different industrial services.

Does Your Boiler Is Simple Vertical Boiler?

Yes, our vertical boiler is a very simple type.

• You will get a simple and compact skid-mounted vertical boiler.
• You will buy it with fewer boiler auxiliaries.
• Your installation is more easy and simple.
• The simple vertical boiler can operate by connecting the water and electric circuit.
• Your operation is more simple.
• One button starts and stops it. Different alarm systems help your vertical boiler keep safe all the time.

What Are The Difference Vertical Boiler vs Horizontal Boiler？

Horizontal boilers and vertical boilers divide according to the outer shape of the boiler.

Under normal circumstances, the horizontal boiler refers to a boiler product with a larger quality and high work efficiency.

The vertical boiler refers to a small boiler product, which is generally less than 700 kW.

Based on that, the two types of boilers have the following different characteristics.

• Different heating capacity

Yongxing simple vertical boiler has limited space for fire pipes or water pipes because the external drum stands, and it can only provide a maximum of 2 tons, which is equivalent to a 1400kw boiler.

If a larger boiler is required, you need a horizontal boiler. Because it can increase the number of fire tubes and use the three-pass flue gas flow design to better utilize heat and achieve greater output.

• Different heat transfer

Vertical boiler exhaust gas stream flows from top to bottom and perpendicular to the heating surface. Its exhaust gas temperature is evenly distributed on the same section;

Boiler heat exchange performance is relatively good, and heating surface uses efficiency is fairly high.

Horizontal boiler exhaust gas flow is horizontal, with the hot air flowing upward, and the exhaust flue gas temperature on the same section is high and low.

Compared with the vertical type, its heat exchange performance is not good, and the utilization effect of the heated surface is not ideal.

• Different degrees of difficulty in cleaning dust

Normally, a vertical boiler exhaust gas flow is traveling vertically from top to bottom along the boiler heating surface pipe, which causes the ash deposited in the pipe of the upper layer. This is hard to remove and easily deposited on the next layer.

Due to our horizontal boiler’s high flow rate of smoke gas, its ash removed is easily carried into the rear by the exhaust gas, which makes your boiler rear block ash.

When these two types of boilers encounter the problem of ash cleaning, they can be solved by continuous ash cleaning.

• Different floor space

Our simple vertical boiler occupies a relatively small area, which solves the trouble of layout and placement of boilers in special places such as urban buildings, buildings, and small production plants.

At the same time, it effectively shortens the length of the exhaust gas pipe and reduces the resistance.

The horizontal boiler needs a relatively large area, and exhaust gas pipes at the inlet and outlet of the boiler are relatively long, which will occupy an area and further increase the system resistance at the rear end of the boiler.

• Different soda and water cycles

Our vertical boiler height meets the requirements of natural circulation of steam and water, so it can reduce the boiler’s failure points;

Yongxing’s simple vertical boiler can also reduce power consumption and save capital investment and expenditure.

However, the horizontal boiler is far from satisfying the natural circulation of steam and water in terms of height but requires a forced circulating water pump. Therefore, the addition of a forced circulation pump will increase its power consumption. There will happen damage to the circulation pump, which has to requires regular maintenance later.

To solve this problem, Yongxing uses stainless steel feedwater pumps for each vertical boiler and horizontal boilers.

There are very few maintenance problems so that your boiler runs worry-free.

How Is Your Vertical Boiler Fuel Regulations? 

Vertical boiler fuel regulations depend on the vertical boiler types.

• Natural Gas, Light oil Or Propane

When you are ready to fire the Natural gas or Light oil gas fuel, you would need the LHS fire tube boiler. We install a boiler oil burner or boiler gas burner in the basement of the vertical boiler.

• Coal, Biomass, Wood pellets

Once you decide to use boiler fuel of coal or biomass. Yongxing has designed a chain grate inside the boiler. Leave an inlet mouth to let you feed the wood or coal.

If you choose to use the wood pellets, Yongxing can also add biomass silos beside the boiler to realize automatic feeding.

• Heavy oil or waste oil

Heavy oil and waste oil is special type fuel. This request high standard boiler burner to meet the system. You have to invest more compare with the above 2 types of fuel. But in the following operation, you save a lot of fuel fees.

For a different kind of fuel, we shall supply you with a special chimney. Your vertical boiler flue has to through the roof of your boiler house.

What Is the Vertical Fire Tube Boiler?

Yongxing vertical boiler can divide into vertical water tube boiler and vertical fire tube boiler according to the water or high temperature flue gas inside the pipeline.

The vertical steam boiler design difference is that the vertical fire tube boiler will use hot gas to go through the boiler cylinders, while the vertical water tube boiler will use hot water.

Yongxing is a very famous vertical model steam boilers supplier in China Market. Of course, we are exceptional on the vertical boiler and professional on a horizontal steam boiler.

What Types Of Your Vertical Boiler For Sale?

Yongxing vertical boilers can be divided into different categories.

• According to the purpose, it can be divided into vertical steam boilers, vertical hot water boilers, and vertical boiling water boilers;
• According to the pressure, it can be divided into vertical pressure-bearing boilers and vertical atmospheric boilers;
• According to the fuel type, it can be divided into liquid vertical boilers, solid vertical boilers, gas vertical boilers, and new energy vertical boilers.

1. Liquid fuel vertical boilers mostly refer to oil-fired vertical boilers and methanol vertical boilers.
2. Solid fuel vertical boilers can be divided into coal-fired vertical boilers and biomass vertical boilers.
3. Gas fuel vertical boilers can be divided into natural gas vertical boilers, coal gas vertical boilers, and liquefied petroleum gas vertical boilers.
4. New energy vertical boilers mostly refer to electric vertical boilers.

Well, The above is the breakdown of vertical boiler products, but generally speaking, we divide it according to the types of fuel, and the most used are gas vertical boilers, oil-fired vertical boilers, and electric vertical boilers.

Gas fired vertical boiler:

Gas-fired vertical boilers mostly refer to vertical boiler products that burn natural gas, LPG, propane gas, etc. It has many advantages such as low operating cost, high thermal efficiency, easy installation, and intelligent operation.

However, the prerequisite for using a gas vertical boiler is that the local natural gas pipeline has been opened, and the opening fee of the natural gas pipeline is also required.

Oil-fired vertical boiler:

Oil-fired vertical boiler refers to a vertical boiler product that burns light oil or heavy oil, that is to say, it burns diesel and heavy oil. This kind of boiler is roughly the same as a gas boiler. The main boiler used is the same, but the burner is used It’s different.

Electric vertical boiler:

An electric vertical boiler is a boiler product that burns electricity. It heats the electric heating group in the boiler through electric heating and heats the water in the boiler to increase the temperature of the water to achieve the purpose of hot water or boiling water and steam.

Electric vertical boilers have many advantages such as intelligent operation, high thermal efficiency, safety, and reliability, but the high operating cost is an important factor considered by users.

Can I know Your Vertical Steam Boiler? What Is Your Vertical Steam Boiler For Sale?

Yes, of course, you can learn about vertical steam boilers. A vertical steam boiler means that the outlet of the boiler pipe is steam. Compared with hot water, steam has a wider range of uses.

Our vertical steam boiler has the following kinds:

1. Coal-fired vertical steam boiler LHG

You can use a coal-fired vertical steam boiler.

It can be a vertical horizontal water pipe or a vertical upright water pipe steam boiler.

Inside horizontal water pipes are directly flushed by the flame, circulating hot water inside.

Yongxing vertical water tube steam boiler has the most popular design at present. It can obtain the corresponding amount of steam with a small volume.

However, Its shortcomings are also very obvious that the combustion chamber is relatively small. So his workability is limited.

        2. Oil gas fired vertical steam boiler LHS

For oil and gas vertical steam boilers. Its main design is where the burner is placed.

1. The burner can be placed on the top.

Steam can be produced quickly, and a small volume and large steam boiler can be realized. But he has a fatal flaw, that is, it is easy to happen crack, not easy to repair. So we don’t recommend it.

2. The burner is placed at the bottom.

In this way, the heat of the burner is from bottom to top, the bottom tube sheet is in the water, which is not easy to crack, and it is also more helpful for fuel combustion.

What Is Your Vertical Hot Water Boiler?

• Vertical Hot water boiler

Yongxing vertical hot water boilers include vertical normal pressure hot water boilers and vertical pressure hot water boilers.

Vertical atmospheric pressure hot water boiler refers to a hot water boiler without any working pressure, while vertical pressure hot water boiler refers to the boiler under pressure during operation. The main difference is that the outlet water temperature of the atmospheric pressure boiler generally does not exceed 100 ℃ Celsius.

The outlet temperature of the pressure hot water boiler will exceed 100℃Celsius. A normal pressure hot water boiler doesn’t need authority during installation, while the pressure hot water boiler must be filed and inspected by the local department.

The main purpose of a vertical hot water boiler is to produce hot water, which can be used for heating or bathing in winter. We are sure to say that it is an essential boiler product in the lives of residents.

Advantages of vertical hot water boiler:

1. Vertical hot water boilers generally have minimum size while needing the shortest time to install. Not only can they meet the needs of small living, but they are also easy to operate and have high thermal efficiency. Compared with horizontal hot water boilers, they are an economical boiler product.
2. The operating cost of the vertical hot water boiler is relatively low. Because its use is more common, the vertical hot water boiler of various fuel types can meet the production needs, which will reduce the operating cost and avoid excessive fuel waste.

Is Vertical Hot Water Boiler Same With Vertical Steam Boiler?

They are not the same. Vertical Hot Water Boiler mainly produces hot water, while Vertical Steam Boiler mainly provides steam to users.

Different sizes of space

Vertical steam boiler belongs to a kind of high-pressure vessel. It is heated to turn water into steam, and the steam is compressed to provide heating. Generally speaking, the pressure vessel occupies a smaller area.

The vertical hot water boiler is a pressureless container. Relying on the temperature of hot water to achieve heating, professional hot water boilers occupy a large area but can achieve better safety.

Hot water boilers can also be divided into atmospheric 0Mpa hot water boilers and pressurized 0.1~1.0Mpa hot water boilers. However, the use of atmospheric pressure vessels can better ensure your safety.

Different heating speed

On the working of vertical steam boiler, because the water evaporates to produce heat, it needs a large amount of heat to burn to ensure the production of steam, so the temperature rises quickly and falls quickly.

However, vertical hot water boilers ensure the temperature by heating water when in use, and the heat capacity of the water is better, so it can better supply heat to maintain the heat.

Different heating ranges

The heat storage capacity of water and steam has a large gap, so high-selling hot water boilers can use transport pumps to transport heat over long distances, with less loss and a large heating radius, up to 50km or more.

However, due to the rapid condensation of steam inside the boiler, the pipe resistance loss is limited, and the heating radius is only 2-7km.

Therefore, the heat supply range that the two types of boiler equipment can withstand is not the same.

Different water circulation modes

Hot water boilers need to continuously supply water to the boiler, while steam boilers have different requirements for water supply. The natural expansion of steam will fill the pipes for steam boilers, while hot water boilers must use electric water pumps to force the circulation of hot water.

Different thermal efficiency

The efficiency of steam boilers is mostly lower than that of hot water.

For example, the heating temperature of a vertical pressurized hot water boiler is low. Generally, Hot water boiler’s outlet temperature is between 110-150 ℃. When heating, it is all sensible heat without latent heat.

The vertical hot water boiler has low combustion temperature, low exhaust gas temperature, and low loss; a low temperature of hot water sent out, low heat loss from pipes. There is no need for continuous sewage discharge, and the loss is small;

Of course, the boiler efficiency largely depends on the manufacturer of the steam boiler or hot water boiler. You can trust YONG XING BOILER GROUP CO., LTD

Do you Manufacturer Vertical Cross Tube Boiler? 

Yes, we till make the vertical cross tube boiler.

All the tubes were installed horizontally in the boiler drums, water flew inside the cross tubes.

We install them horizontally upper the furnace fix grate, and they will directly receive the radiant heat energy generated when the fuel is burned.

Can We Know The Simple Vertical Boiler Construction And Working Principle？

The working principle of a vertical boiler is to use the heat released by the combustion of fuel to convert it into steam or hot water. The fuel can be coal, putting the coal manually on the grate, which heats up quickly and pressurizes quickly.

It can also burn biomass particles, which are automatically loaded and burned, and produce steam or hot water, which is environmentally friendly and pollution-free.
