Title: Incinerator with auxiliary gas evacuating apparatus
Inventor: KEBIN DEII MAKUGURASU
IPC: F23L17/16
Filed: 1994-03-18
Abstract: PURPOSE: To remove harmful gas from an incinerator when a scrubber fan is troubled by changing over a solenoid valve to an open position and flowing compressed gas into a main pipe of the incinerator via a valve and an annular chamber. CONSTITUTION: When a scrubber fan 47 is disengaged, a solenoid 51 is released from excitation to change over a valve 53 to an open position. Compressed gas flows from a tank 57 to an air stream amplifier 41 including an annular chamber 77. The compressed gas flowing in the air stream amplifier 41 generates small negative static pressure at an inlet end of the amplifier 41 (at an outlet end of a first pipe 1) to prevent residual gas in the first pipe 1 and a second pipe 3 from escaping from an open end of the first pipe 1. Further, with the action of the air stream amplifier 41 the residual gas in the first pipe 1 is likely to be absorbed through the incinerator toward a scrubber. The compressed gas and the air stream amplifier are available as main means for feeding gas into the system.
