GAS TURBINE WITH AUXILIARY COMBUSTION BURNER AND CHILLER HEATER

PURPOSE:To increase the amount of heat to an absorption water heater as well as to aim at effective utilization for energy, by installing an auxiliary combustion burner in an exhaust gas pipe line, in case of a device which utilizes waste heat having high temperature exhaust gas out of a gas turbine for a heat source for a absorption chiller heater. CONSTITUTION:High temperature exhaust gas, after knocking off work with a gas turbine 3, enters a high temperature regenerator 7 of an absorption chiller heater by way of exhaust gas pipes 4-6 and, after its heat is recovered and made into low temperature, discharged to the atmosphere via ducts 8 and 9 and a smokestack 10. At this time, if a waste heat value out of the gas turbine 3 is larger than the required heat value, opening of a damper V1 in a bypas duct 19 is adjusted so properly whereby an exhaust gas quantity to be led into the high temperature regenerator 7 is restrained. On the other hand, when it is hard to cover the required heat value with the said waste heat value alone, a burner 21, which is supplied with fuel from a fuel pipe line 20 and air from a fan 23, is operated whereby a fuel quantity to be fed to the high temperature regenerator 7 is made so as to be increased.
