Coal Boiler Definitive Guide FAQ

Yongxing Coal Boiler provides you with industrial boilers. Guiding you about Coal Steam boilers is the main focus of the provided information. You can find the different capacity coal boiler types by contacting us. The first reason you should choose us is the low-cost boiler accessories and auxiliary boiler system. Focus on the FAQ guide to remove your queries about the boilers.

What Is A Coal Boiler?

In simple, the coal boiler is mainly for coal fired steam boiler, which is industrial machinery that uses coal as fuel, absorbs the coal heat, and turns the hot water into steam. Your coal will burn on the chain grate stoker and generator heat. This heat conduct to upper pipes and drums, you will get steam finally.

In the heating industry, coal acts as the standard fuel source. Our boiler supplied several different types of coal:

  • lignite coal
  • anthracite coal
  • AII bituminous coal

If you want a steam boiler for industrial applications, then coal is the best fuel to use the steam boilers. You can burn it completely in comparison to the bricks. This fuel source tends to ground to a fine powder in industrial applications. A combustion reaction between coal and air operates the coal steam boiler.

What Are Your Coal Boiler Types?

Being the best 4A class coal-fired boiler manufacturer in China, Yongxing Boiler Group provides you with the best boilers. We provide you with different models of a coal-fired boiler. These models include a coal-fired steam boiler, coal-fired hot water boiler, and coal-fired thermal oil heater. In these types, we mainly provide DZH, DZL, and SZL. These boiler types are discussed below:

1. DZH Coal boiler

Some of the advantages that our design of coal steam boiler provides include:

  • Smoke Concentration

We provide you with enhanced combustion technology in our steam boiler design. Your steam boiler comes with an increased combustion chamber. This chamber ensures that you get one that discharges the minimum exhaust smoke concentration.

  • Heating Speed

The design of the steam boilers we provided you includes a new type of finned threaded smoke pipes. We adopt this to increase the heating speed. In comparison with tube boilers, this method increases the heating speed by 1/3.

  • Heat Loss

The coal boiler design for you will include finned tubes that ensure to minimize heat loss. With these finned tubes, the efficiency of the design gets far higher than other products.

  • Flexibility

We connect the vertical longitudinal pipes on both side headers to the upper horizontal boiler drum. This is to ensure good flexibility in your design. The connection also eliminates the bulge defects in your coal-fired boiler.

  •  Compactness

The design of the coal-fired boiler we provide for you is very compact. You can save the boiler room area with the same capacity. The design also covers an extensive load adjustment range of 0-110% load.

How Does Your Coal Boiler Work?

Our coal boiler has coal as its fuel. There is a water-containing vessel in a steam boiler that generates heat by coal into steam in your boiler. It transfers this heat into pipes and then directs it to the point. Through these points, the coal-fired steam boiler runs your industrial equipment. Converting water into heat using coal is the basic idea of the coal-fired steam boilers you use in your applications.

  • Mechanism of the System

In the working of your industrial coal-fired steam boilers, there are few mechanisms. There are separate parts of the system at different points.

  • Heat Source

The heat source will be in a separate area with the water vessel for heat conversion. There is a connection between the heat source with the vessel and the metal rods. These rods play the main part in converting the water into steam by heating it with the help of your coal source.

  • Vessel

After converting water into steam, it gets in the vessel or dome in the above section. From this vessel, it gets out of the boiler. Before steam exits the system, the dome condenses the steam. It does the function of condensing to build up pressure. You may require pressurized steam to run your application. In those processes, it is the main part.

  • Safety Valves

There are some safety valves in the boilers for your safety. These valves ensure that the boiler releases excess steam to avoid explosions. Your system also contains a chimney that is there to ensure heat escapes.

What Do You Do To Warranty Your Coal Boiler Quality?

We ensure the coal boiler you buy process strictly accord with our following way.

  • Steel sheet blanking, circle round, tube plate drilling, Yongxing all adopt advanced CNC processing technology, reduce assembly stress of your pressure components, and prolong your coal steam boiler lifetime.
  • Longitudinal and girth welding boiler adopts an advanced automatic submerged arc welding process to ensure the dzl boiler you buy with the best welding quality.
  • If you add our silencer to the forced draft fan and induced draft fan, you will get a coal steam boiler that runs at ultra-quiet 80dB.
  • The unique fire grate bar ensures that your traveling grate runs smoothly. Our boiler chain grate stoker will test run 72 hours before delivery to ensure the chain grate looseness is moderate and does not deviate.
  • A strict quality inspection ensures that every boiler you buy is safe and secure. Yongxing’s every industrial coal boiler for you is 100% longitudinal and girth weld radiographic, altogether avoiding unqualified welds.
  • Yongxing set up seven points for different quality inspection personnel to sampling, respectively. Unqualified products are repaired directly. Your boiler is enjoying Yongxing’s 40 years of production technology on welding and drilling.
  • We equip with reasonable air distribution and a large combustion surface, therefore, your coal boiler heat efficiency will be 5%-15% higher than the conventional coal steam boiler.

What’s The Different Between Your dzl Boiler & SZL coal boiler?

Compared with the traditional dzl boiler, Yongxing SZL coal boiler types have added a horizontal pot in the rear end. If the DZL can only provide a maximum of 8-10 tons of steam, then Yongxing SZL coal steam boiler will give you 6ton to 40ton of steam per hour.
