Product Details

Product Features
Centralized coal powder supply: Coal powder is centrally ground and supplied by the powder mill, ensuring stable coal powder quality.
● Work environment friendly: The entire system operates in a closed manner, with automatic coal loading, centralized ash discharge, and no dust emissions.
● Simple boiler start stop: The boiler system can be started and stopped immediately, cutting off the ignition source and entering normal operation within 30 seconds; Cutting off the coal powder supply can achieve shutdown.
High level of measurement and control: automatic monitoring and adjustment of operating parameters to keep the system in the optimal operating state; Simultaneously reducing labor intensity and human factors affecting the pot
The impact of furnace operation.
Efficient and energy-saving: sufficient coal powder combustion, good boiler heat exchange effect, small excess air coefficient, high system thermal efficiency; Equip high-power electrical equipment with transformers
The frequency converter has a significant energy-saving effect.
● Clean emissions: Coal powder boilers can implement desulfurization inside the furnace, and the burner adopts a low-temperature air classification design. The combustion temperature field is uniform, avoiding local high temperatures and combustion
Low levels of SO2 and NOX generated during the process; The flue gas is treated with bag dust removal, resulting in low concentration of smoke and dust emissions; The fly ash collected by the bag filter is discharged through a closed system and sent to
Centralized processing and utilization, without secondary pollution.
● Land conservation: Cancel the coal yard and slag yard next to the boiler room to save land and investment.

Environmental indicators of high-efficiency coal powder industrial boilers
Combustion efficiency ≥ 98%
Boiler heat efficiency ≥ 88%~90%
Emissions of particulate matter (TSP) ≤ 50mg/Nm3
The emission of sulfur dioxide (SO2) can meet local environmental requirements
(It can meet the requirements of the local regulations on environmental protection.)
Emission of NOx ≤ 500mg/Nm3
