FAQ

 

1. What are the spare parts of DZL/SZL series coal/biomass boilers?
Usually, spare parts are instrument valves, grate plates, gaskets, etc.
2. What is the difference between DZL and SZL of the same capacity?
DZL
1. It is usually used for boilers with a capacity of less than 10 tons
2. Easy to transport
3. Low requirements for water quality
4. Boiler room construction charges are low
5. Low water quality requirements
SZL
1. Usually suitable for larger capacity boilers
2, good water circulation, small water volume
3. Faster preheating and higher steam quality
4. Higher requirements for water quality
5. Higher thermal efficiency
3. What is the difference between vertical boiler and horizontal boiler with the same capacity?
1. Vertical boiler has compact structure and limited floor space.
2. Easy installation and disassembly.
3. Low cost of capital construction and less investment.
Steam consumption is rapid and abundant.
1. The horizontal combustion space is large, and the fuel can be burned.
2, the thermal efficiency is higher than the vertical boiler,
3, horizontal: less heat loss, stronger output, higher steam quality.
4. What are the limitations (size, humidity, chemical concentration) of coal/solid/wood fuels?
Size requirements of coal: 6-25 mm
Coal blending size requirements: <50 mm (less than 6 mm coal should be less than 30%)
Biomass particle diameter: 6 ~ 10 mm, length: 25 ~ 50 mm, water content <15%, ash <2%, sulfur content <0.07%, chlorine <0.07%, nitrogen <0.5%
5. What are the dimensions of the furnace door and blower hopper?
Door size:
Standard oval furnace door: 300*800*1500
Blower hopper size:
2 tons conical hopper: 1400*800*1500
4 tons cone hopper: 2200*1400*1500
6. What is the combustion mode of coal/biomass fired boilers?
The combustion mode of coal/biomass boiler is stratified combustion. The flue is placed on a fixed or moving grate to form a uniform fuel bed with a certain thickness, and the air comes out from the bottom of the grate and combustion occurs on the fuel bed.
7. What is the thickness of the refractory?
Thickness of refractory: 50-60 mm
8. What is the installation sequence?
Boiler - economizer - Dust collector -ID fan - chimney
