explain about bhel high pressure boiler - Benson Boiler is a high pressure, drum less, supercritical, water tube steam boiler with forced circulation. This boiler was invented in the year 1922 by Mark Benson. This boiler is a super critical boiler in which the feed water is compressed to a supercritical pressure and this prevents the formation

Condensing boiler - Wikipedia

Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted.This condensed vapour leaves the system in liquid form, via a drain.

Common Steam Boiler Problems & How to Troubleshoot Repairs

As with other boiler problems, clean the boiler of any contamination caused by foaming before correcting the water chemistry problem. Treating the water with anti-foaming agents prevents the chain reaction caused by foam production. The chemicals alter the surface tension to prevent any solids from creating foam in the water.

(2) Lowering of boiler safety : Due to scale formation, over-heating of boiler is to be done in order to maintain a constant supply of steam. The over-heating of the boiler tube makes the boiler material softer and weaker and this causes distortion of boiler tube and makes the boiler unsafe to bear the pressure of the steam, especially in high-pressure boilers.

High pressure boilers (1) - SlideShare

Dec 09, 2015 · A boiler is called a high pressure boiler when it operates with a steam pressure above 80 bar. The high-pressure boilers are widely used for power generation in thermal power plants. In high-pressure boiler if the feed-water pressure increases, the saturation temperature of water rises and the latent heat of vaporization decreases.
