Coal mill pulverizer in thermal power plants

2.Coal 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 panels.Pulverizers 101: Part I,Every coal pulverizer is designed with a particular fuel grinding capacity or throughput at a certain Hardgrove grindability index (HGI), based on a defined raw coal size, moisture content, and,pulverizer raw coal size - Mine Equipments,Coal mill pulverizer in thermal power plants - SlideShare 17 Nov 2012,Pulverizer The pulverizer receives the raw coal and reduces it to a very fine, specified size consist, similar to

Coal Pulverizer Maintenance Improves Boiler Combustion

Pulverizer capacity is not simply a measure of coal throughput; capacity refers to a certain coal throughput at a given fineness, raw coal sizing, HGI (Hardgrove Grindability Index), and moisture.Pulverizer Capacity is not simply “tons throughput per hour!”,Pulverizer capacity is comprised of five major factors. These are throughput, fineness, Hardgrove grindability, moisture content and raw coal size. Therefore, throughput is only one component of pulverizer capacity. All five factors play a part. For example, when the fineness is reduced, the throughput can be increased without the pulverizer,Coal Pulverizer Mill Size - gtecoaching,The Storm Approach to Coal Pulverizer Optimization. The design "capacity" of the same pulverizer will grind 135,000 pounds per hour with fuel that is 55 HGI (Hardgrove Grindability Index) coal, ¾" raw coal top size, 7% moisture and produces pulverized coal that is 70% passing 200 mesh fineness (red line).

Coal Pulverizer

Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.Pulverized coal-fired boiler - Wikipedia,The raw coal is then fed into the pulverizer along with air heated to about 650°F / 340°C from the boiler. As the coal gets crushed by the rolling action, the hot air dries it and blows the usable fine coal powder out to be used as fuel. The powdered coal from the pulverizer is directly blown to a burner in the boiler.Optimum Operation and Maintenance of EL Pulverizers,Raw Coal Size. Maintaining optimum sizing of raw coal to the pulverizer is mandatory in achieving capacity and fineness. Optimum raw coal feed size for EL pulverizers is ¾” to 1”. Raw coal feed should never exceed 1¼”, raw coal this size can plug throats and cause vibration. Raw coal
