The source of the problem is the coal pulveriser mills not being able to produce the more stringent fineness required. This results in coal/char particles burning higher up in the furnace, causing excessive reheater temperatures, etc. One could attempt to increase the rotational speed of the vertical spindle mills by at least 15%.

Two major parameters which decide the mill capacity and performance are the hardness of coal and the total moisture level in coal. The mill outlet temperature of coal-air mixture is maintained between 65 to 90 degree centigrade in the case of low and medium volatile coal. In the case of high volatile coal while the lower limit generally remains as 65 …
Quantity measurement on the feed belt to the coal mill To fuel the power plant boilers, chain conveyors must first bring raw coal from the bunkers. Feed belts (distributors) then transport the coal to the coal mill, where it is ground into dust and blown into the boiler. In order to ensure the
Valmet CFB Boiler (formerly CYMIC) is an advanced circulating fluidized bed (CFB) boiler developed by Valmet. It combines high-efficiency combustion of various solid fuels with low emissions, even when burning fuels with completely different calorific values at the same time. The wide size range covers boilers from 30 to 1200 MWth.

mixture. Since a large boiler burns over 40 kg (88 lbs) or more of coal per second, the safe burning of pulverised coal necessitates strict adherence to planned operating procedures. STRENGTHENING PLANT SAFETY IN COAL GRINDING MILLS AND STORAGE SILOS WITH CARBON MONOXIDE MONITORING
Fuel preparation for a pc boiler occurs in a mill, where coal is typically reduced to 70% through a 200-mesh (74-μm) screen. Figure 2 shows a particle-size distribution from a bowl-mill grinder typically used in power plants. A typical utility specification for particle size distribution of the coal is that 70% of the mass should pass through a 200-mesh screen, …

Primary air fans deliver pulverized coal from crushing mills to burners. These are high-pressure, high-efficiency fans that both convey the coal and provide combustion air for the boiler. Fans used in conveying and dust collection systems for coal operations should be both spark-proof and abrasion-resistant.
Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum and the other 50 % is governed by fuel properties like hydrogen in fuel, moisture in fuel and ambient air conditions. The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few …
The majority of coal-fired boilers worldwide have the Π-type configuration, also known as a two-pass boiler.
