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 …
Answer (1 of 3): It depends on what type of coal you are using. But generally coal shall be around 50 mm (diamwter approx) afte crushing in crusher which is again powdered or pulverised in the mill to the size of 70% through 200 mesh (50 microns) before admitting into furnace via burners.
Many plants like coal fired power plants, cement facilities and cogeneration industries employ coal bunkers to store coal and coal mills to crush the raw material into fine particles before being injected into the boiler. x AZ30 – economic point in-situ oxygen ZrO 2 probe xLS25 – fastest cross-stack carbon monoxide laser measurement
A conventional coal-fired power plant produces electricity by the burning of coal and air in a steam generator, where it heats water to produce high pressure and high temperature steam.The steam flows through a series of steam turbines which spin an electrical generator to produce electricity. The exhaust steam from the turbines is cooled, condensed back into water, …
