GAS TURBINE COMBINED PLANT

PURPOSE:To carry out a proper combustion of pulverized coal even if the O2 is low in the exhaust gas of a gas turbine by combining the gas turbine and a circulating fluidized bed boiler. CONSTITUTION:The exhaust gas of a gas turbine 1 is divided into two halves. One of them is introduced as the prim...

Summary:PURPOSE:To carry out a proper combustion of pulverized coal even if the O2 is low in the exhaust gas of a gas turbine by combining the gas turbine and a circulating fluidized bed boiler. CONSTITUTION:The exhaust gas of a gas turbine 1 is divided into two halves. One of them is introduced as the primary combustion air through a feed water heater 11, system 9, fan 12, and nozzle 13 to a circulating fluidized bed boiler 2 from its bottom. And, the other half of the exhaust gas is introduced into the circulating fluidized bed boiler 2 as secondary combustion air from the wall on the side of the furnace through the system 10.
