The coal fired steam boiler after improvement takes use of structure of wing type smoke duct, one-way screwed smoke tube, arched tube plate, smoke and gas separate room and several other advanced technology, which has increased the water circulation speed and safety factor. This boiler series is well designed, compactly made up, quickly installed, mono layer, so that the civil engineering and investment could be saved. With these improvement, the boiler's working life extend much to be the national energy saving product.

1-6T steam boiler usally transported as entiraty part, Capacity more than 8t(including 8 t/h)are transported as up body and bottom body (chain grate)

Coal Fired Boiler Burning process

Fuel falls from coal hopper onto the front of chain grate, moves along with the chain grate and will be preheated, dried, ignited, burned out. Slag will be discharged by slag remover(eliminator) at any time. Herring bone arch is adopted to improve igniting condition. Smoke forms between front and back arches vortex, completely mix with air, burns out and then goes after each other through smoke flue at two wings, front smoke box, threaded smoke tubes, cast iron economizer(for hot water boiler no cast iron economizer), dust remover, draft fan and will be emitted through chimney.

Performance advantage

DZL series coal fired steam boiler is the single drum longitudinal type water and fire tube shell water boiler, the burning equipment is the chain grate.

1. The fire grate is compact and dense. It is especially suitable for the combustion of biomass particles.

2. Boiler internal heating area is larger than the same specifications of coal-fired boilers, to make up for the disadvantage of biomass fuel combustion value.

3. The condition is stable, continuous fuel combustion. By adjusting the secondary speed air volume, control the speed of combustion ignition.

4. The biomass steam boiler is easy to operate, user-friendly design, without complicated procedures.

5.It takes the thread smoke tube to enhance heat transfer, improve the heat transfer coefficient and thermal efficiency.

Due to disturbance of smoke in the tube, the smoke pipe is not easy to accumulate dust ,it can clean by itself .

6.Fuel easily obtained, the ash can be recycled.

-automatic fuel feeding duel to chain grate design;

-high efficiency due to big heating surface and grate area;

-low emission,friendly to environment;

-wide fuel adaptability, applicable for wood pellet, coal, palm nuts, etc;

-intelligent boiler controller with PLC and touch screen, easy for operation and parameters setting;

-good looking & long life span;

Application scope:

This steam boiler is used for producing desired steam for manufacturing process in the weave factory, printing and dyeing, papermaking and other industry like: food, rubber, plastic, chemical, pharmaceutical, etc, and for heating room and bath in factories, departments, hotels, schools, restaurants, services industries etc.

2 tons conical hopper: 1400*800*1500
4 tons conical hopper: 2200*1400*1500

 

2.What is the combustion mode of coal/biomass fired boiler?

The combustion mode of coal/biomass fired boiler is layer combustion. Place the flue on the fixed or moved grate, to form an evenly fuel bed with a certain thickness, air comes from the bottom of grate, and combustion occurred on the fuel bed.

 

3.Material of boiler drum / steel plate / tube.

Boiler drum material: Q245R,carbon steel, executive standard: GB713-2008
Tube material: 20# seamless steel pipe, carbon steel, executive standard: GB3087-2008
Still kettle material: Q345R, alloy steel, executive standard: GB713-2008

 

4.What is the height of chimney?

The chimney is usually 30m, irrespective of the special circumstances.

 

5.What are the heat-resistance temperature of grate and furnace?

The heat resistance temperature of grate is related to the grate material, the highest temperature could be as high as 1100℃, and the lower temperature could be 700℃.

 

6.What is the temperature of smoke gas?

The highest temperature of smoke gas is 165℃.

 

7.How long can the coal/biomass fired boiler works?

Coal/biomass boilers could work for 10~15 years, under correct operation, high water and coal quality, etc.

 

8.How to avoid collapse of bricks, and what should be done if it happened?

When boiler installation finished, drying the boiler according to the manual, it’s very important to avoid collapse of bricks.
