STEAM POWER CYCLE

STEAM POWER CYCLE . Power plants generate electrical power by using fuels like coal, oil or natural gas. A simple power plant consists of a boiler, turbine, condenser and a pump. Fuel, burned in the boiler and superheater, heats the water to generate steam. The steam is then heated to a superheated state in the superheater.

In a simple Rankine steam cycle, the boiler gives steam at 60 bar and 550°C. The condenser operates at 0.1 bar. If both pump and turbine efficiencies are 90%, estimate the cycle efficiency. 10.2. In a reheat Rankine cycle, a CSP system gives steam at 50 bar and 400°C.

Minimize Boiler Short Cycling Losses

A boiler cycle consists of a firing interval, a post-purge, an idle period, a pre-purge, and a return to firing. Boiler efficiency is the useful heat provided by the boiler divided by the energy input (useful heat plus losses) over the cycle duration. This efficiency decreases when short cycling occurs or when multiple boilers are

Is your boiler “short cycling”?

A boiler is short cycling when the burner goes on and off in short periods of time. Short cycling leads to a lot of wear and tear on the boiler and also leads to higher energy usage. Short cycling is not good! Short cycling results in the heating load being a lot smaller than the boiler’s heat output.
