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 Steam Boiler?
In simple, the coal-fired steam boiler 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:
DZH is a single drum boiler that comes with both a water tube and a fire tube. The convection heating area of this boiler type is the two wings at the furnace. You will see a spirally corrugated tube in the drum. Its furnace structure provides you with high efficiency. You can find it suitable for many industrial applications and manufacturing processes.
DZH coal-fired steam boilers are useful in industrial applications. You can use these boilers in Textile, Food, Chemicals, Plastics, Rubber, Paper, Wood, and other industries applications. The DZH coal-fired steam boiler type we provide includes:
- DZH6-1.25-All Active Boiler Grate Coal Boiler
- DZH6-1.25-All 1.25Mpa Small Steam Coal Boiler
SZL boiler is a chain traveling grate with a double furnace in line. It comes with a convective heat-exchange surface design that provides a high heat transfer rate. You’ll get good steam quality because of the reasonable water circulating system, larger water content, and steam space.
Our boiler operates smoothly and has a potential for overload. A large convection surface provides this smooth operation. It is suitable for you for many industrial and manufacturing processes.
Some of our SZL steam boilers include:
3. DZL boiler
You’ll get DZL that has a quick-loading coal-fired boiler design. It comes with a single boiler drum and longitudinal layout pipes.

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 steam 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.
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.
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-Fired Steam Boiler Work?
Our coal-fired steam 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 the connection of 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.
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 all 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 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.
