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.
