Pulverized Coal Fired Steam Boilers is an industrial or utility boiler that generates thermal energy by burning pulverized coal also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup that is blown into the firebox The basic idea of a firing system using pulverized fuel is to use the whole volume of the furnace for the combustion of solid fuels...

Pulverized coal firing is the method of choice for large industrial boilers eg 250000 lb steamh and coalfired electric utility generators since pulverized coalfired units can be constructed to very large sizes ie up to ≈ 1300 MW or ≈ 95 million lb steamh and unlike stoker units where some designs have coal restrictions
Coal pulverized to 65 passing 200 mesh was then pumped to the bunkers in the boiler house where it fed 11 Stirling Wtype boilers generating 360000 lbh of steam at 420 psi725°F 250°F of superheat The boilers were vertically down fired with each unit using 16 fishtail burners
Pulverized coal stationary blade feeders are designed for even feeding of pulverized coal from intermediate hopper to boiler burners The feeder consists of the following major units receiving hopper with lock dozing machine safety coupling worm reduction
Coal pulverizers are the heart of a pulverized coalfueled boiler Often the root causes of nonoptimized combustion lie with the pulverizers
• From 1 mill up to 20 mills • For all kinds of coal black lignite anthracite bituminous • Independant of fuel quality • Easily retroffited to existing pipe The Dynamic Flow systems identify unbalanced pulverized fuel distribution and helps in • Optimizing on line combustion • Decreasing Loi emission • Reducing Nox emission • Improving boiler efficiency
Coal is pulverized in the coal mill to a very fine particle size The coal and primary air are then introduced to the coal nozzle The coal and primary air are then introduced to the coal nozzle Swirled air coupled with the burner throat’s flowshaping contour enables recirculation patterns that extend into the
Combustion tuning of a pulverized coal boiler begins with balancing the air and fuel flows in the coal pipes from the pulverizers to the burners Note that each of the coal pipes is a different
A coalfired power station is a type of fossil fuel power coal is usually pulverized and then burned in a furnace with a furnace heat converts boiler water to steam which is then used to spin turbines which turn chemical energy stored in coal is converted successively into thermal energy mechanical energy
Boilers Pulverizers To efficiently combust coal it needs to be pulverized into fine particles 100μm before being placed in a boiler A pulverizer coal pulverizer is installed for this purpose and pulverizes pieces of coal several centimeters in diameter down to fine particles
