ABSTRACT:
The temperatures of exhaust gas streams into a black smoke eliminating device are uniformly raised to assuredly burn and eliminate the black smoke at the black smoke eliminating device. Accordingly, the restoration of the black smoke eliminating device is uniformly carried out while avoiding melt damage of the filter.
Further, the exit temperature of the black smoke eliminating device is descended by a simple device of lower cost.
For accomplishment of the present objects, the heating device and black smoke eliminating device are provided in a plural and divided manner and there are provided a baffle member and a space portion, to thereby equalize the volume quantities and temperatures of exhaust gas flows flowing into these devices.
Further, the fuel is atomized into fine particles by injection into pressurized air and the obtained mixture is uniformly mixed into the exhaust gas, so that there are uniformly raised the temperatures of exhaust gas streams into the black smoke eliminating device.
The temperature of exhaust gas is descended by a simple structure of porous body disposed downstream of the black smoke eliminating device.
