Abstract

PURPOSE: To dispense with a chimney for a combustion furnace, by providing a convergent discharge cylinder and a damper at the downstream end of a vertical exhaust cylinder branched from a duct which connects a combustion furnace to a waste heat boiler.
CONSTITUTION: High-temperature exhaust gas produced by incineration in a combustion furnace 2 is supplied to the waste heat boiler 5 through a duct 3a, another duct 3 and a damper 4 so that the heat of the exhaust gas is recovered. The gas is then discharged through another damper 6, an induced draft fan 7 and a chimney 8. In an emergency such as a trouble in the waste heat boiler 5, the damper 4 is closed and another damper 15 is opened to rapidly discharge the exhaust gas upward straight from the convergent discharge sylinder 14 provided at the downstream end of the vertical exhaust cylinder 13. The exhaust gas can thus be discharged to a desired height without using an emergency chimney.
