Generation of Steam • Water is converted to steam (in a boiler) using a basic source of energy –Fuel oil, natural gas, wood, coal, heating element –One of the above is used to generate hot gases which heat the metallic surface (usually steel) in contact with 9

Boiler efficiency measures how much combustion energy is converted into steam energy, while steam quality measures how much liquid water is present in the steam produced. A major benefit of using steam as a heat transfer medium is the large amount of heat released when it condenses into water.

2019/7/23 · This ensures constant TDS and steam purity at the given steam load. Once blowdown valve is set for a given condition, there is no need for the regular operation of the valve. This type of blowdown is common in high-pressure boilers and a heat recovery system is also instead to recover the heat of blowdown water.

The steam then drives the turbine which is coupled to the electricity generator. The excess heat generated can also be used for other purposes, e.g. heat for swimming pool. Exhaust gas cleaning - The exhaust gas from the boiler is typically cleaned by the following advanced pollution control systems to ensure compliance with the stringent environmental standards
