DZL coal fired chain grate boiler realizes almost zero pollution with the use of special dust collector solution (bag dust collector, double towers desulfurization, etc.), it is honored as Chinese famous brand. This series boiler is single drum horizontal type shell boiler with three-pass structure, the combustion equipment is chain grate (small scale flaker is available), has the advantages of feed mechanically, strong adaptability of different fuels, low coal leakage, and convenient maintenance. The fuel is coal, the diameter should be 6-25mm, and ash content should be less than 32.4%.

This DZL series coal fired chain grate boiler uses the new scientific achievement, such as arch tube plate, spirally corrugated tube to solve the problem of low thermal efficiency, tube plate cracking, drum bulging, insufficient output, and environmental pollution. Sitong Boiler has a mature R&D and design team, could customize the boilers based on customers’ requirement.

Performance Advantages

1. Excellent chain grate

1) The small scale chain grate boiler could resist the temperature as high as 1200℃, long working life.

2) The chain grate has a low coal leakage because of the small gap.

3) High automatic degree, decrease labor cost.

4) Convenient for maintenance, it could be done without boiler shut down.

5) Based on customers’ requirement and fuel characteristics, the grate could be designed as small scale grate, chain belt grate, bar grate, etc.

2. High thermal efficiency

1)The spirally corrugated tube strengthen the heat transfer, improve thermal efficiency. The flue gas has the foundation of disturbance, avoid ash depositing in tube.

2)The furnace wall was poured entirely by the heat-resistance concrete and high-temperature-resistance refractory brick, and the boiler shell use aluminium silicate board for heat preservation, low heat loss.

3) Equipped with economizer, make full use of the heat of flue gas, decrease the exhaust smoke temperature, increase thermal efficiency.

3. Avoid bulging

The riser tube bundle under the drum, remove the dead water region at the bottom of drum, sludge is not easy for depositing, the high temperature area of drum has better cooling, prevent bulging.

4. Avoid tube plate cracking

1) The steam boiler adopts arched tube plate and spirally corrugated tube, change the quasi-steel body into quasi-elastic body structure, reduce stress, solves the problems of tube plate cracking.

2) Arrange two sides gas duct in drum, the smoke gas could enter into the front smoke chamber smoothly, the temperature of tube plate is lower than 600℃, avoid cracking leaded by high temperature.

5. Sufficient output

Adopts horizontal type three pass structure and large furnace, to ensure the sufficient combustion, and the boiler could absorb the thermal expansion effectively. The large diameter boiler drum increases the radiant heating surface, to ensure the sufficient output.

6. Environmental protection

1) The splayed wall and smoke outlet have the function of dust removal, decrease the concentration of smoke emission.

2) The moving grate boiler adopts several environmental protect measures (bag dust collector, double towers desulfurization, etc.) to meet the national emission requirement.

Boilers Application
Medicine, chemical, light industry, textile, building material, cultivation, food and beverage, plastic foam, printing, dyeing and washing, rubber processing, paper products,wood processing, hotel, clothing and leather manufacturer etc.

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.
