An In-Depth Guide To Yongxing Steam Boilers

As a professional steam boiler manufacturer, we create China Top class steam boilers for industrial uses.

Given our reputation, we receive many questions regarding our steam boilers, how they work, installations, and more. As such, we’ve compiled a list of commonly asked questions for your own use.

What Is A Steam Boiler?

Simply put, every industrial area needs either heating or hot water to function – that’s what steam boilers are used for.

The steam boiler operates various kinds of fuel to generator steam, such as gas, oil, biomass, and wood.

Industrial always classify and name many steam boilers based on their type of fuel burned. In addition to steam used in daily life, a big amount of steam will be used for industrial purposes.

Generally, If your industry needs a lot of steam to fulfill the operations, you need to buy a large industrial steam boiler to achieve it.

As such, you can use steam boilers for many reasons.

Here are a few examples of different industries and what they use a steam boiler for:

  • Food/Beverage Industry:
    to process and cook meats and other foods that require high temperatures. Additionally used for sanitization and cleaning practices as well.
  • Laundry for Commercial aim:
    Industrial steam boiler uses to clean, press, and iron clothing. The hotel has a large number of bed sheets, quilts, etc. that need to be cleaned, and steam must be used to achieve high-temperature cleaning and disinfection.
    Often hospitals require this too. Patients’ gowns, bed sheets and quilts require high-temperature sterilization and disinfection. Hospitals are usually equipped with larger steam boilers.
  • Production Factories: 
    Steam is also suitable for different factory operations, such as chemicals, textiles, galvanizing, food, etc.

What’s The Difference Between A Steam Boiler And A Hot Water Boiler?

At Yongxing, we supply both steam and hot water boilers. While these boilers work in similar ways, it’s best to know the difference between the two.

  • Hot water boilers have much lower heating temperatures than steam boilers. Steam boilers high heating temperatures to properly turn fluid within the boiler into steam.
  • Steam boilers are much stronger and efficient than hot water boilers, particularly for the needed capacity of an industrial environment.
  • Steam boilers can use both high and lower pressures.

How Does A Steam Boiler Work?

Steam boilers can be complicated, especially when you delve into all the various parts. As such, we’ve simplified how a steam boiler works so you gain a thorough understanding.

In the boiler compartment, fuel and air combine to heat the water. When the water reaches a high temperature, it then produces steam. The steam then travels to the main steam pipe and is dispersed depending on what the heat is needed for. When the steam cools down, it then condenses into water form again. It then travels back to the boiler area and the process is repeated.

At Yongxing, we offer 2 different kinds of steam boilers: fire tube steam boilers and water tube steam boilers. Fire tube steam boilers involve hot gas running through a tube that ultimately heats the water surrounding the tube. We generally recommend individuals to purchase fire tube steam boilers when the fuel input is natural gas, light, or heavy oil.

On the other hand, water-tube steam boilers involve water running through the tube and the water is heated by the fuel surrounding it. Generally, this requires less fuel to operate and less time to start up as well. When high steam pressures are required, water tube boilers are ideal.

What Types Of Steam Boilers Do You Offer?

We offer multiple steam boilers for sale. According to inside the burning conditions, you could get two types of steam boilers: fire tube boilers vs water tube boilers.

Fire Tube Boilers

 

Natural Gas Boilers is kind of fire tube boilers. Which utilizes natural gas, LPG, propane as fuel. You have an efficiency rate of 94% or more with it.

Your steam boiler combustion rate is highly productive. it allows hot flue gas to go through 3 cycles, dramatically increase its heating efficiency.

Different from gas fired steam boiler, oil fired boiler takes light oil, kerosene oil, heavy oil, or waste oil as the fuel. It also belongs to the fire tube boiler.

Although vertical steam boilers are smaller in size, they fully fill with power. As it is vertical short fire tubes, our vertical boilers can provide heat very quickly.

Our smaller steam boilers are capable of generating steam within 3-5 minutes and are meant for smaller working capacities. We also offer a generous 50% discount on our small steam boilers.

Compared to other commercial steam boilers from different manufacturers, ours are 2-3% more efficient. Given the construction of these boilers, multiple steam boilers can connect and work together simultaneously.

Water-tube boilers

 

Coal-fired boiler Boiler pipes are filled with hot water that will eventually be turned into steam for your use. For such a boiler where water flows in a pipe, we call it a water-tube boiler.

To save heat, you could buy an economizer and air preheater together to increase efficiency. Our traditional design shall be 84~86% right now.

Wood fired Steam boiler is a choice of large wood and a fixed rate. Its mechanization degree is not high, can not achieve full automation. But as it is applicable to a wide range of fuel, low investment costs, so It can meet the needs of many rural enterprises.

With increased advancements in technology, we’ve managed to maximize the potential of our pellet-fired boilers.

Along with the environmental benefits, our SZL type pellets fired boiler is able to build a big silo and help you to hold a large number of pellets, by which you will realize large heat production.

Electric Steam Boiler

If you’re looking for an environmentally friendly option for your steam boilers, we suggest using an electric steam generator. These electric boilers are smaller and are generally safer to use given it only needs electricity to run.

We can provide clients with anything from 4 – 10Bar with low voltage steam boilers.

 

There are a variety of steam boilers that we offer for the convenience of our clients. You’ll have a wide variety of steam boilers to choose from depending on what’s more optimal for your steam boiler needs.

The specifications of each model of steam boiler range in terms of its rated steam capacity, max transport weight, etc.

Additionally, we carry lots of different fuel operating steam boilers. All of our boilers are certified and tested with proof of efficiency and safety as well. Choose these various steam-generating boilers we offer at Yongxing.

What Are The Parts Of A Steam Boiler?

Each steam boiler part is meant to increase the efficiency and capacity of our steam boilers. As an example, we list all of the steam boiler parts of the WNS Low Condenser Steam Boiler.

  • Boiler: Where the heat transfer is done between the fuel and the fluid.
  • Water tank: The pre-treated water performed in the water softener is then transferred and stored in the water tank.
  • Water softener: A pre-treatment equipment. This part treats the water to make it less corrosive and removes foreign particles that can lead to difficult build-up to treat.
  • Circulation pump: Pushes the hot water to radiators or other distribution areas. These pumps also bring back any water from condensation.
  • Deoxygenation pump: removes the oxygen from the water.
  • Feed Water Pump: a particular pump that pumps feed water into a steam boiler.
  • Burner: Where fuel source and air are combined together.
  • Condenser: Fueled by gas or oil condensing the water vapor for greater efficiency.
  • Steam Header: It supplies steam to general areas that may need it. It is considered the main steam pipeline.
  • Deaerator: Used to remove oxygen and other gases. This is removed to ensure that corrosion does not occur.

How To Calculate The Steam Flow Rate Of Boilers?

Knowing the steam flow rate helps with understanding the efficiency of each boiler. It puts into perspective how much steam (which is being used to heat an area) can be produced per hour. To calculate the steam rate flow:

Feedwater Mass Flow = Steam Mass Flow/ [ 1 – Blowdown Rate]

For example, our high-quality machines like the one-piece low condenser boiler produce up to 20 T of steam per hour.

How Is The Installation Process?

At Yongxing we have already pre-assembled parts within our factory. We can then transfer it to the site to complete the rest of the assembly. We make the installation process of our steam boilers to be very simple for your convenience. Better yet, it also saves you time!

How Much Does The Steam Boiler Cost?

The cost of our steam boilers is extremely low. We charge the factory pricing of each steam boiler to ensure that each client can have the opportunity to purchase a boiler for an affordable cost.

Can I Use This For Residential Purposes?

Yongxing purely makes products according to industrial usage. Industrial steam boilers are much larger in size, which has the capability to provide heat to larger spaces. For example, hospitals, commercial buildings, universities require the use of an industrial boiler to effectively heat a given area and provide an adequate supply of hot water.

For residential areas, steam boilers required are much smaller in size to heat up an average-size home.

How Do I Clean The Steam Boiler?

The steam boiler cleaning process is simple but should be performed by a professional. With the convenience of our steam boilers, you won’t have to worry as much about cleaning as using other industrial boilers.

Chemical cleaning is an essential part of maintaining any industrial steam boiler. Generally, both the water and fuel portions of the steam boiler must be cleaned. Here are some reasons as to why:

  • When water is heated to a high temperature, minerals from the water start forming around the boiler. As this leads to build-up, it can lessen the lifespan of your steam boiler.
  • On the fuel area, overtime soot can form. As such, this soot must be removed and cleaned in order to make combustion more efficient.

While Yongxing boilers are highly efficient and can prevent the huge accumulation of build-up, these instances are bound to happen. The cleaner the boiler system is, the more efficient the boiler can be. Additionally, the build-up of equipment can lead to possible fire hazards.

What Safety Features Are Included With Your Steam Boilers?
