What are the advantages of pulverized coal boilers?

Centralized Coal Powder Supply: Coal powder is centrally milled and supplied by the pulverizing plant, ensuring stable coal powder quality.

Friendly Working Environment: The entire system operates in a closed environment, with automatic coal feeding, centralized ash removal, and no dust leakage.

Simple Boiler Start-up and Shutdown: The boiler system can be started and stopped instantly. It takes 30 seconds to cut off the ignition source and enter normal operation; cutting off the coal powder supply can achieve shutdown.

High-level Measurement and Control: Automatic monitoring and adjustment of operating parameters ensure optimal system operation, reducing labor intensity and the impact of human factors on boiler operation.

High Efficiency and Energy Saving: Complete coal powder combustion, good boiler heat exchange, low excess air coefficient, and high system thermal efficiency; variable frequency drives are equipped for high-power electrical equipment, resulting in significant energy savings.

Clean Emission: The coal-fired boiler can implement in-furnace desulfurization. The burner adopts a low-temperature air staging design, with a uniform combustion temperature field, avoiding local high temperatures, and resulting in low SO2 and NOx content during the combustion process; the flue gas is treated with a bag filter, resulting in low dust emission.

The fly ash collected by the bag filter is discharged through a closed system for centralized processing and utilization, preventing secondary pollution.

Land Saving: Eliminating the coal storage yard and slag yard next to the boiler room saves land and investment.
