In coal crusher coal size reduced up to ¾" after that coal transfer to the boiler's coal bunker or coal yard. In the case of emergency the coal is fetch from coal yard. Coal feeder control the quantity of coal from coal bunker and send it to the ball mill or roll mill for pulverization process. Where coal crushed to .
In order to meet coal variations and to optimize combustion, mills are important equipment for pulverized boilers. Highperformance mills offer outstanding pulverization and classifiion and promise lower unburned carbon, more variety of coals, and higher ratio of cofired biomass fuels.

Boiler in Sugar Mill In fact, most cane sugar factories have been designed to be energy selfsufficient, with sugar as the primary product and bagasse as the primary fuel. A bagassefired cogeneration system, made of steam boilers and steam driven turboalternators, provides all the steam and electricity needed to run the cane mills and factory, leaving little surplus bagasse.
The boiler manufacturers only modified the fuel input equipment or modified the basic boiler parts to accommodate the transfer of additional air, ash, or the fuel itself. Refuse, wood, and biomass boilers are similar to the utility radiant boilers and industrial boilers that burn coal. They fall into the egory of "wastetoenergy" 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

· 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.
coal handling facilities, pulverising mills, boiler, air heater, ESP, ash disposal as well as stack emissions. Coals have different characteristics and heat content. The behaviour of a coal in a boiler is strongly influenced by its rank and by the mineral matter and other impurities associated with it. Coal

· Coal Feeder is a device that regulates the amount of coal to be supplied into the Coal Mill. The amount of coal is regulated according to the needs in the boiler combustion chamber (furnace). The number regulation system in the coal feeder can be done in two ways based on the type, namely by weight fraction or coal volume fraction.

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.
