Coal Ash Circuit – this circuit deals mainly with feeding the boiler with coal for combustion purposes and taking care of the ash that is generated during the combustion process and includes equipment and paraphernalia that is used to handle the transfer and storage of coal and ash; Air Gas Circuit – we know that air is one of the main components of the fire Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, etc Two major parameters which decide the mill capacity and performance are the hardness of the coal and the Boiler Performance and Mill Outlet Temperature Bright Hub Engineering The initial process in coal based thermal power plant is coal handlingThe Function of coal Handling Plant in thermal power plant is to receive , process, store, feed the coal bunkers consistently over entire life of the power plant Coal is transported in thermal power station either by railways,roadways or rope waysCoal Handling System Coal Handling Plant In Thermal Power
The coal is first crushed into minute particles using equipment called pulverizes The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion This process is used to create the steam that is the primary process in the thermal power plant In power plants, the PA fans supply air for Pulverized coal is the most efficient way of using coal in a steam generator The coal is ground so that about 70 % will pass through 200 mesh (0075 mm) and 99 % will pass through 50 mesh (0300 mm) A pulverized coal boiler can be easily adapted for other fuels like gas if required later without much difficultyCoil Pulverizers for Boilers Bright Hub Engineering Thermal Power Plant Layout Important Terms Used In Thermal Power Plant Or Steam Power Plant Saturation Temperature – It is the temperature for a corresponding saturation pressure at which a liquid boil into Thermal Power Plant COAL HANDLING PLANTS
