Title:
PRESSURIZED FLUID BED ROLLER COMPOSITE POWER GENERATING EQUIPMENT
Document Type and Number:
Japanese Patent JP3181379
Kind Code:
B2
Abstract:
PURPOSE: To operate a catalyst denitration device at an early stage by providing a circulating water piping so as to guide the boiler circulating water separated by a steam separator to the water supply inlet of an exhaust gas cooler positioned upstream from a catalyst denitration device in the gas flow line, and recirculating the boiler circulating water to the water supply inlet of the exhaust gas cooler when the system is started.
CONSTITUTION: The heat generated by the combustion is discharged from a fluid bed boiler 1 to a gas piping 2, and guided to a gas turbine 4. When the system is started, the fluid from the outlet of an evaporator 9 is separated into steam and water by a steam separator 12 in order to keep the in-tube flow speed at the specified value, and the separated water as the circulating water is mixed with the feed water at the inlet of a high temperature exhaust gas cooler 16 through a boiler circulating pump 13 and a circulating water piping 14. Thus, the temperature of the feed water at the inlet of the high temperature exhaust gas cooler 16 rises, and the inlet gas temperature of a denitration device 17 rises. This constitution allows the denitration device 17 to be operable at an early stage.
