given pulverizer are a function of coal conduit size, fuel moisture and throat ring flow area. In any case the actual curve must be above a minimum allowable curve. The minimum curve has four components which must be calculated and coordinated: Minimum line velocity, minimum A/F ratio, minimum slope, and the resulting inflection point.
pulverizer capacity. Capacity of a pulverizer is a minimum of five factors and these five factors are: tons throughput at a given fineness, at a given Hardgrove grindability index (HGI), at a given raw coal sizing entering the mill and at a given coal moisture content. Throughput alone is NOT a definition of pulverizer capacity! Please read on
COAL MILL PULVERIZER in THERMAL POWER PLANTS . 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. . located on the top of a mill returns the oversize material back to the pulverizer but allows the propersized .
A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
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). This is pretty standard.

Coal mill pulverizer in thermal power plants SlideShare. Nov 17, 2012· 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 .
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.
Design of Pulverizers . Every coal pulverizer is designed with a particular fuel grinding capacity, or throughput, at a certain Hardgrove grindability index (HGI), based on moisture content, a defined raw coal size, and desired fineness level. These factors must all be considered and are significant in discussions of pulverizer capacity.
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.
coal size by attrition (impact of coal on coal, and coal on moving and stationary parts). There is no metaltometal contact of pulverizing elements. Conventionally, a rejector located between the pulverizing and fan sections controls pulverized coal fineness. Vshaped rejector arms at high rotating

A coalfired thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam, and spins a steam turbine, which drives an electrical generator, as schematically shown in Fig. it passes through the turbine (one to three stage), the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle.
