A -fired 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 19After 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 cycleGet a Quote
The time energy and facility required to is much lesser than pulverizing coal PC firing uses around 30 % of the combustion air as high pressure primary air for drying and transporting fuel CFB uses higher pressure primary air which is 60 % of the combustion air for fluidizingGet a Quote
Crushed from the raw bunker is fed by gravity to a dryer where hot air is passed through the to dry it The dryer may use waste flue gasses preheated air or bleeder steam as drying The dry is then transferred to the pulverising mill The pulverised obtained is transferred to the pulverised bunker (bin)Get a Quote
[en] As the power industry looks to the 1990s for expanded steam generation capacity owners will continue on their long-standing assignment to evaluate and select the best lowest cost alternative to meet their energy needs For -fired plants this evaluation process includes -fired (PC) and circulating (CFB)Get a Quote
· Combustion (FBC) of As has already been indicated one of the most promising trends in reducing emissions from burning is by FBC There are two versions of combustion: bubbling and circulating (CFB) the latter being a second generation processGet a Quote
To efficiently combust it needs to be into fine particles (100m) before being placed in a A () is installed for this purpose and pulverizes pieces of several centimeters in diameter down to fine particles The includes pulverization drying and classification functionsGet a Quote
