COAL BASED THERMAL POWER PLANTS: COAL MILLS
Ball tube mills are either pressurized or suction type In the pressurized type, the hot primary air is used for drying the coal and to transport the milled coal to the furnace In this type, leakage in the mill area is highIn the suction type, the exhauster is used for lifting the milled coal from the pulverizer to the furnace through a cycloneFor example, the are used to pulverize coal for combustion in the steamgenerating furnaces of fossil fuel power plantsTypes of Pulverisers: Ball and Tube mills; Ring and Ball mills; MPS; Ball mill; Demolition ii) Dryers: they are used in order to remove the excess moisture from coal Thermal Power Plant Working Indian Power SectorIn coalfired power stations, the raw feed coal from the coal storage area is first crushed into small pieces (in the crusher department) and then conveyed to the coal feed hoppers at the boilers The coal is next pulverized into a very fine powder The pulverizes may be Ball/Tube Mills, Vertical Mills or EMillsThermal Power Plants Shri Balaji
Coal mill pulverizer in thermal power plants
2Coal pulverizer/mill system One of the critical power plant components that is relied upon to convert the energy stored in coal into electricity is the coal pulverizer or mill The coal flow is controlled by the feeder, allowing coal to flow into the pulverizer mill The pulverized coal and air mixture is then transport to the boiler burner Understanding of coal mill system21 Types of coal mills Coal mills are categorized based on the speed into three categories namely, low speed, medium speed, and high speed mills Low speed and medium speed mills are the most popular ones in a coal fired thermal power plant and are discussed below 211 Operation of low speed millsReview of control and fault diagnosis methods 2 The coal mill The work presented in this chapter is based on a MKM33 ball mill used at Rybnik Unit 4 (rated capacity 220 MW) The mill is one of six mills supplying the 650k (steam production of 650 t/h) boiler However, the proposed method in this chapter is so generic that it can be applied to other types of coal millsDetection of Malfunctions and Abnormal Working
