Minhang Power Plant, Shanghai Electric Power Co., Ltd..99 Мб 2. For coal mills A and C that operated under a 100 MW load, the measured boiler efficiency improved by % when the combustion optimization system was put into service; thetested parameters according to the emission standard of all pollutants for thermal power plants GB.
Coal mill is an important component of the thermal power pla nt. It is used to grind and dry the moisturized raw coal and transport the pulverized coal ± air mixture to the boiler. Poor dynamic performance of coal mill will lead to decrease in the overall efficiency of the power plant, slow load take up rate and fr equent shut down.
Pulverizing solid fuel to powder enables its drying and transport for combustion in large furnace sizes. Fine grinding increases the fuel exposed surface area while simultaneously drying and controlling its distribution. These are integral steps to efficient, low emissions combustion which are optimized together with boiler thermal performance.
The system of guiding the rollers in rocker arms is designed to accommodate a swingout device; by connecting up an auxiliary cylinder to the rocker arm. The rockerarm/roller unit can be pivoted completely clear of the mill housing. Loesche roller grinding mills are the most efficient mills in the world and achieve very high throughputs.

Coal dust is a fine powdered form of coal, which is created by the crushing, grinding, or pulverizing of coal. Because of the brittle nature of coal, coal dust can be created during mining, transportation, or by mechanically handling is a form of fugitive dust.. Grinding coal to dust before combusting it improves the speed and efficiency of burning and makes the coal easier to handle.
