This steam boiler uses the new scientific achievement, such as arch tube plate and corrugated tube, to solve the problem of tube plate flaw and water wall tube explosion, improve the heat transfer efficiency and thermal efficiency, increase the output. The boiler is wide adoptability of different fuels, such as coal, biomass fuel, wood, straw, bagasse, rice husk, coconut shell, etc.

Technical Parameters

Performance advantage

1, the use of efficient heat transfer components - threaded smoke pipe, with a reasonable flow rate of flue gas, boiler thermal efficiency than the national professional standards of 6-8 percentage points higher.

2. Arched tube plate and threaded smoke pipe make the pot shell change from quasi-rigid body to quasi-elastic body, and cooperate with airfoil flue, completely avoid the defect of cracking of high temperature tube plate of traditional firework tube boiler.

3. Reasonable water circulation loop and unique backwater ejector device (hot water boiler) can improve the water speed of rising pipe and avoid the pipe bursting of water-cooling wall.

4. Adopt the inertial separation of smoke and dust in the furnace, supplemented by efficient multi-pipe dust collector, so that the dust concentration of the boiler can meet the requirements of a class of areas.

5. Reasonable boiler structure can support its own weight without steel frame.

6, the use of energy saving, strong radiation furnace arch, can ensure the stable combustion of fuel.

7. Adopt high standard and high quality auxiliary machines, accessories and automatic control equipment to ensure the safe and stable operation of the boiler and reduce the labor intensity of the stoker.

8. Compact structure, 1-20T /h(0.7-14MW) boiler can be arranged in one layer.

This coal steam boiler is widely used in schools, textile mills, clothing factories, printing and dyeing factories, restaurants, food factories, beverage factories, bean products factory, meat products factory, cannery, winery, pharmaceutical factory, packaging factory, building materials factory, coating factory, swimming pool and other enterprises and institutions.

FAQ of coal fired boiler

1.What is the size of furnace door and blower hopper?

Size of furnace door:
Standard elliptical furnace door:300*800*1500
Blower hopper size:
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.

9.How many stokers do I need for one boiler?

Usually 3 person, every 8 hours a shift.
