pulverized coalfired boilers, and solid oxide fuel cells(2) This paper reports on the development of technology to cofire ammonia and pulverized coal aimed at reducing CO 2 emissions from coalfired power plants Induced Draft Fan (IDF) to draw in the air supplied to the10012017· Induced Draft Fan Induced draft fan is normally located at the outlet between dust collector and chimney The fan takes hot flue gases from the boiler through dust collector and delivers it to the chimney into the open atmosphere ID fan creates negative pressure or suction to discharge the gases out after combustion from the furnacePA Fans, ID Fans, Draught Fans, FD Fans, SA Fans in

Induced Draft fans namsaetrading2012

Induced Draft fans The Induced Draught fan draws flue gases out of the boiler, On coal and biomass fired boilers the Primary air fan moves air through the air preheater The hot air exiting the preheater is mixed with the pulverized fuel and the air flowwhich means 2% more air pressure drop and gas draft loss which translates to 3% more fan horsepower requirement on the forced draft and induced draft fans Pulverizer capacity is particularly sensitive to coal moisture An increase in coal surface moisture from 5% to 14% can reduce the output of the pulverizer to 74% of its original capacityThe Role of Coal Characteristics in Boiler Operation

Cause of Boiler Slagging

Boiler Slagging has many causes, and the most important ones are as follows 1 The impact from coal type The cause of boiler slagging has a direct relationship with coal type If coal is of poor quality and large ash content, it is easy to form coking 2 The impact from pulverized coal quality26062012· Such coals may contain up to 70% water and ash, yielding lower furnace temperatures and requiring larger induceddraft fans The firing systems also differ from black coal and typically draw hot gas from the furnaceexit level and mix it with the incoming coal in fantype mills that inject the pulverized coal and hot gas mixture into the boiler1 CLASSIFICATION OF INSTRUMENTS IN POWER PLANT
