Improved Modern Control Station for High Pressure Bypass

Thermal power plant main energy transporter is steam. In a 210 MW thermal power plant, the boiler drum pressure is 160 kg/cm2 and the temperature is 540° C. The steam is generated in the boiler drum. This steam is fed to the turbine for power generation. The turbine is converting the thermal energy in to mechanical rotational energy.:International Journal of Advanced Research in Electrical, Electronics and Instrumentatio:P Karthikeyan · A Nagarajan · A Vinothkumar:Omics[PDF]A Large-Capacity Pressurized-Fluidized-Bed-Combustion Large-Capacity Pressurized-Fluidized-Bed-Combustion-Boiler Combined-Cycle Power Plant OVERVIEW: To improve the thermal efficiency and environmental characteristics of coal-fired power-generation systems, The Chugoku Electric Power Co., Inc. and the Hitachi Group developed the first commercial 250-

Boiler (power generation) - Wikipedia

Haycock and wagon top boilers. For the first Newcomen engine of 1712, the boiler was little more than large brewer's kettle installed beneath the power cylinder. Because the engine's power was derived from the vacuum produced by condensation of the steam, the requirement was for large volumes of steam at very low pressure hardly more than 1 psi (6.9 kPa) The whole boiler was set into brickwork

Why Economizer and Air Pre-Heaters are Provided in Boilers

Boilers are provided with economizer and air pre-heaters to recover heat from the flue gases. Boilers operate with around 86 to 90% efficiency depending upon the type of fuel and design adopted. A degrease of about 20 % of boiler efficiency is seen by not providing both economizer and air pre-heaters.

High Pressure Boilers: Features and Advantages ~ ME Mechanical

Oct 27, 2016· A boiler is called a high-pressure boiler when it operates with a steam pressure above 80 bars. The high-pressure boilers are widely used for power generation in thermal power plants. In a high-pressure boiler, if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
