Chat Online· The coal feed can be controlled by the speed of the conveyor belt. Table type rotary feedersThis are just paddle feeders or blade feeders which load on to conveyor and the conveyor discharge the fuel into the pulverisers. Gravimetric type of feedersThis is used for feeding the coal from the bunker to pulveriser as per requirement. 2.3
Chat Online· Numerical simulation of the influence of operating conditions of the furnace on its performance characteristics like heat flux distribution Furnace Exit Gas Temperature (FEGT) and NOx emission levels was performed for a tangentially fired pulverised coal boiler. The results revealed that the FEGT and NOx emission are slightly higher when the top seven coal nozzles are in operation

Chat Online· The flow field within the pulveriser is slightly asymmetric mainly due to inclined vanes. The region above the pulveriser vane sections towards the left of the inlet duct clearly indicates high velocity zones which is in accordance with the plant observations. This is expected to increase the wear pattern in the lower sections of the mill. ⋅
