Product Description for efficient pulverized coal fired

 industrial boiler of WN S series 

1. Central supplying of pulverized coal : Pulverized coal shall be centralized ground and

integrated supply in the factory, ensuring high quality of pulverized coal .

2. Friendly work environment: The whole system shall use closeness running, automatic-coaling,

and centralized ash discharge without dust to spill.

3. Easy in starting and stopping for boilers: The boiler system shall achieve start- and -stop. It

shall run normally following cutting off ignition source in 30 seconds. As soon as it cuts off coal

dust supplying, the boiler system shall achieve blowing out.

4. High level of measuring and controlling: Automatic monitoring shall be used, as well as

adjusting working parameter, as a result, the system shall be at its best running state, reducing the

risk of boiler running on which labor intensity and human factor effect.

5. High-efficiency & energy-saving: The boiler shall featuret the following: Pulverized coal

burning brightly,excellent heat transfer effect of boiler, low excess air coefficient of boiler , as

well as high thermal efficiency of system . House-service equipment with high power shall use

frequency-changer, economizing on electricity obviously.

6. Discharge kept shall be clean: Furnace desulfurating shall be performed in the pulverized coal

boiler. Burner shall be equiped with cryogenic air classifier with uniform ignition temperature

field, avoiding high-temperature , so the content of SO2 and NOX produced in combustion

process is low. Fume shall employ bag filter with a low smoke dust level. Fly ash, collected by

bag filter, shall be expelled from closed system, resulting in centralized treatment and utilization

without secondary pollution.

7. Optimal land utilization: Coal storage and slag dump shall not be heaped around the

boiler room, economizing on land and saving investment.
