Technologies and features:
1. Design of shaped furnace and overall boiler shell, low temperature combustion, high efficiency, easy self-cleaning.
2. Pulverized coal furnace can desulfurize in the boiler, and burner is low nitrogen type, therefore, in the same time of ensuring the burning out of coal, to avoid the local high temperatures. Using advanced dust collector of highpower concentrated dust bag in the end, sulfur dioxide and nitrogen oxides produced by combustion process are very low. Therefore, emission values are far below the national and local current emission standards, and environmental effect is very significant.
3. Equipped with intelligent and automatic monitoring system, achieving automatic control and regulation of boiler operation, the continuous automatic acquisition of operating parameters, fault display and chain protection.
4. Small area of boiler, fully enclosed operations in the process of coal transportation, staged combustion, smoke removel achieving a clean working environment.
5. In order to adapt to boiler capacity and the needs of different users, there are two processes of centralized boiler system for tanks and blast furnace pulverized coal powder milling buffer tank.

Characteristics of coal boiler
1. Remarkable energy saving effect
a. The coal powder is less than 200 μsm;
b. sufficient burning for the suspension firing way;
c. thermal efficiency is higher than 86%.
d. frequency control for power saving;
e. The boiler can be started or stopped at any moment; the starting time is less than 2 minutes.
2. Remarkable environmental effect
a. Low Nitrogen burner, then very low content of sulfur dioxide, and nitrogen oxide.
b. Wet bag type dust-collecting system.
3. High degree automatization
a. Full-automatic intelligent monitoring system
b. The operator can turn on the ignition at any moment, after 30 seconds the boiler can go into the normal operation.
4. Low running cost
a. Coal saving rate is higher than 30%.
b. Energy saving rate is higher than 30%.
5. Good working environment
a. Fully enclosed running of coal handing, burning, Dust-collecting and desulfuration etc.
b. Clean coal boiler room.
