Boilers
Pulverized Fuel Boilers Pulverized coal boilers fire finely powdered coal, typically with an average particle size of about 25 µm ( in). Coal burns in suspension, like the combustion in an oil or gasfired boiler. Coal is pulverized in some type of large mill Pulverized coal is fired out into the furnace
Can we use biomass fuel in coalfired boilers?
Biomass boilers are different from coalfired boilers. The grate gaps of coalfired boilers are too large for wood pellets. In biomass boilers, the wood pellets are gasified and fed by a hopper at a constant speed so that they can burn sufficiently. After gasifiion, the hearth is .
COAL HANDLING SAFETY
COAL HANDLING SAFETY Risks of unwanted combustion – potentially causing injury, damage and downtime – occur everywhere that coal is handled, processed or stored. Safe coal handling practices are designed to ensure that the fuel remains intact throughout its journey from the mine until the point at which it is ignited in the boiler.

COAL BASED THERMAL POWER PLANTS: COAL HANG UP IN BOWL MILLS
· Bowl mills are used for pulversing coal in pulverized coal fired boilers. The coal to the mill is fed by a coal feeder from the coal bunker. There are many type of feeders used for coal feeding like the belt feeder which can be in volumetric or gravimetric mode, the chain link feeder, the drag feeder, etc. Row coal from the yard is sized in crushers and stored in coal bunkers.
Challenges when Converting CoalFired Boilers to Natural Gas
When evaluating the prospect of converting a coalfired boiler to natural gas, there are a number of factors that need to be independently evaluated. The combustion system modifiions and boiler performance impacts are several important aspects to be considered. The combustion system

AIR FLUE GAS PATH | Power4you
· Before the coal mill we mix both Cold PA and Hot PA and this optimum temperature air is used for drying purpose of coal, which is around 80°C. PA system also varies from design to design. In Cold PA system, PA fan takes air suction from atmosphere and some amount of this air goes to APH(Air Pre Heater) and other half of the air directly goes to a header called Cold PA Header.
