Fundamental Applications of Steam - Forbes Marshall

The used steam is again converted in to water using a condenser. This recovered water is again fed back to the boiler to generate steam. The efficiency of the power plant is directly dependent on difference between pressure and temperature of steam at the inlet and outlet of turbine. Hence, use of high temperature and high pressure steam is

Case Study - Optimizing Steam Supply in a Chemical

2020-11-30 · Case Study - Optimizing Steam Supply in a Chemical Plant by Steve Lyons of Premier Control Waste heat boilers (WHB) are used to produce steam from unwanted excess hot gases from the production of sulphuric acid. These gases are used to pre-heat the feed water in an economiser, and are also fed directly to the boiler via a sulphur gun to

Waste Heat Boiler - an overview | ScienceDirect Topics

Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,. t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, °C.. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.
