steam generator efficiency

Boiler efficiency is the ratio of heat actually absorbed

A boiler produces 4000 kg of dry and saturated steam in 6 hours. In the same time the mass of coal consumed is 300 kg of coal. The mean pressure of steam generated is 11 bar. The temperature of the feed water is 35°C. Determine the boiler efficiency if the calorific value of the fuel is 30000 kJ/kg.

Jun 01, 2007 · Steam Generator Efficiency By Brad Buecker, Contributing Editor. The word "thermodynamics" conjures up visions of complex mathematics to many Condensers. Why must turbine exhaust steam be condensed? Why not transport it directly back to the boiler? The reason is Superheating Mechanics.

Boiler (power generation) - Wikipedia

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Steam boiler fuel to steam efficiency - Steam Generators

Fuel-to-Steam efficiency is equal to combustion efficiency less the percent of heat losses through radiation and convection. For example, as in the example above, 6 kW are lost to convection and radiation then the convection and radiation losses are 2%: 6 / 300 = .02 or 2%. If the combustion efficiency for this same case is 82% then the Fuel-to
