The above are the major water and steam circuit items in a boiler and are collectively called the 'pressure parts'. This post is part of the series: Working Of A Power Plant Boiler. Boiler in a power plant has two functions. The Combustion system converts energy in coal to Heat.
The main function of the Primary air fan or PA fan is to carry the pulverized coal to the furnace as fuel for combustion. This process is used to create the steam that is the primary process in the thermal power plant. In power plants, the PA fans supply air for conveying of the pulverized coal from coal mills .
With adequate mill grinding capacity, a vertical mill equipped with a static classifier is capable of producing a coal fineness up to 99.5% or higher <50 mesh and 80% or higher <200 mesh, while one equipped with a dynamic classifier produces coal fineness levels of .
Apr 09, 2018· The coal power plant diagram shows the components of the plant and the different stages of transforming the chemical energy (coal) into electrical energy as: We started with the boiler or the steam generation system; as we supply the coal from coal bunkers via coal conveyors to be crushed into coal mills.
The overall project involved many areas of the mill, including the power plant and four (4) boilers, controls, wood room and bark system, railroad which transported coal, and the coal distribution system within the facility. Riley Power's engineering design was limited primarily to the boiler systems and included the following: Riley Power Scope
Thermal power plants use different types of coal pulverizers. The method used is attrition, impact, or a combination of both. This article explains the characteristics of the three main types- attrition, impact and attrition, and impact or hammer. Selection of the type of pulverizer depends on the grindability of the coal, the capital costs and maintenance costs, and considerations for licensing.
Pego Power Station is the most modern coal-fired power station in operation in the Iberian Peninsula. It features two electricity generating units, each equipped with a steam generator, one turbine-generator unit and a main transformer. Its main equipment are the boilers, coal mills, turbines, generators and the main control system.
