Optimization of Combustion Efficiency for Supplementally Fired Gas Turbine Cogenerator Exhaust Heat Receptors
Abstract
A broad range of unique cogeneration schemes are being installed or considered for application in the process industries involving gas turbines with heat recovery from the exhaust gas. Depending on the turbine design, exhaust gases will range from 800 to 1000 F with roughly 15 to 18 percent remaining oxygen. The overall heat utilization efficiency and the net effective heat rate of the cogenerating facility varies widely with the degree of supplemental firing of the heat receptor. This effect is explained and its economic significance defined. Other effects are also explored, such as adiabatic and equilibrium combustion temperatures; and variations in radiant versus convection heat transfer in the heat receptor furnace or boiler.
