INDUSTRIAL NATURAL GAS ENERGY EFFICIENCY

For high temperature flue gases it is common to use a steam boiler, commonly known as heat recovery steam generator (HRSG), to produce high pressure (usually >50 pounds per square inch gauge psig) steam and use this steam in a turbo generator to produce electrical power. In this case, the working fluid is

Spray water group mass flow. Normally the mass flow rate of superheated steam (live steam) is known. Thus, mass flow rate calculations start usually by calculating the mass flow rate of spray water to the last spray water group (which is in this example between the second and third superheater stages).
