Title:
ASH CONVEYOR FOR FLUIDIZED BED COMBUSTION DEVICE
Document Type and Number:
Japanese Patent JP3181161
Kind Code:
B2
Abstract:

PURPOSE: To convey ash, collected from exhaust gas of a fluidized bed combustion device through an ash-collecting facility, safely to a bag filter.
CONSTITUTION: The exhaust gas of combustion is employed as gas for conveying ash without employing a part of combustion air such as in a conventional method. For this purpose, high-temperature and high-pressure exhaust gas in an inlet port for a gas turbine 15 is employed after cooling it by a heat exchanger 25 to the low-temperature and low-pressure exhaust gas in the outlet port of the gas turbine 15 is employed after pressurizing it by a compressor 29. The exhaust gas of combustion, in which the concentration of oxygen is extremely low, is employed whereby the spontaneous combustion of unburnt fuel contained in ash in an ash collecting facitlty 14 and the like will never be worried.
