Pulverized coal fired boiler, powdered coal fired boiler

 

Advantage of Bidragon Pulverized Coal Fired Boiler

 

 

l  High efficiency and energy saving: burning rate of pulverized coal is beyond 98%, thermal efficiency is beyond 88%,saving 35%-50% coal than the traditional coal fired boiler. Installing frequency converter on big power electric equipment saved much electric power obviously. Exhaust gas temperature is not more than 150°C.

 

l  Environmental friendly: the pulverized coal burner adopts air staging and low-temperature combustion design, temperature distributing evenly to avoid much NOxproduced by the part burning, lower pollutants emission intensity, pulverized coal ash no secondary pollution after being discharged from the close system. After the desulfurization and bag filter system, flue gas emission reach the following standard: ash<=30mg/Nm, SO2<=100MG/Nm3, NOx<=200mh/Nm3, which level meet station environment requirement and below station emission standard.

 

l  High intelligent PLC or DCS control system: equipped with automatically control technology, boiler running, coal transporting, desulfurization dust removing, etc. is all controlled automatically, which ensures less smoker and better working environment. The system realizes instant start-stop function, cutting off the ignition source for 30 seconds and then run normally. Cutting off feed makes boiler stop. Automatic monitoring and parameter adjusting keeps it best running condition, meanwhile which decreases labor strength and disturb to boiler brought by human factor.

 

l  Safe and reliable: the all system is running in closed system. Pneumatic coal transmission, centralized ash discharge, without ash and dust leakage, totally-enclosed powder process technology, rain and raise dust proof. Adopt high reliable program for ignition controller, which avoid detonation in furnace during ignition and provide flameout interlock protection. Electrostatic grounding and CO2 protection system, avoid spontaneous combustion of pulverized coal in coal storage tower, which provide safety coal storage and combustion safe.

 

l  Highperformancecostratio: High efficient and low operation cost will help customer withdraw equipment investment.

 

l  Smaller floor space:Simple system flow, compact equipment layout, coal and slag don’t fall to the ground, without need of slag storage area, land-saving.
