摘要： PROBLEM TO BE SOLVED: To reduce concentration of an unburnt gas contained in an exhaust gas to an explosion limit and less, and surely prevent explosion in an exhaust gas dust by interposing an agitating device or a catalyst combustion device in an exhaust gas path between a gas engine and an exhaust heat recovery part. SOLUTION: A rotary kiln 3 for necessitating a high temperature as an exhaust heat recovery part is connected to a gas engine 1 of a lean combustion type for rotating a power generator 2 through an exhaust gas path 5. In the rotary kiln 3, a reheating burner 4 for heating an engine exhaust gas of about 500 deg.C to 900 to 1200 deg.C is disposed, and an intake blower 8 is also disposed. In an exhaust gas path (an exhaust gas duct) 5 formed in a zigzag shape, an agitating device 6 is interposed so as to agitate and mix the exhaust gas and unburnt gas by generating a turbulent flow. Accordingly, concentration is sufficiently reduced by uniformly mixing the unburnt gas contained in the exhaust gas, and explosion of the unburnt gas in the exhaust gas duct 5 is surely prevented.

摘要： PURPOSE:To resolve a problem of air pollution, and acquire an energy saving effect while miniaturizing a device and cutting its cost by providing a leakage gas guiding part for guiding leakage gas to the engine intake side. CONSTITUTION:On the holding part of a holding member for a catalyst 1 is provided a closed container in which a space S for introducing leakage gas at the holding part is formed to surround the holding part. And, an outlet 7a for the leakage gas is formed at a suitable position of the closed container 7. The base end of a pipeline 5, whose fore end is connected to the intake side pipeline of an engine 3, for guiding the leakage gas to an engine intake side, or effective utilization of heat energy existing in the leakage gas is connected to the outlet 7a. Thereby, flowing out of the leakage gas into the atmosphere is avoided while attempting miniaturization and cost cutting of the device, so that a problem of air pollution can be resolved. Further, heat energy existing in the leakage gas is effectively utilized in engine operation to cause an energy saving effect.

摘要： PURPOSE:To reduce the amt. of noble metals required for a catalyst and to successively and surely purify the exhaust gas from a gas engine for a long time by incorporating catalytic particles having a low ratio of Rh to Pt and catalytic particles having a high ratio of Rh to Pt into the wash coating layer of a ternary catalyst. CONSTITUTION:The top of a honeycomb carrier is coated with a wash coating layer contg. Pt and Rh as active catalytic metals and Ce as a co-catalyst. At this time, catalysts different from each other in the concn. ratio of Rh to Pt are carried in the wash coating layer and the Pt, Rh and Ce contents are regulated to >=1g, >=0.2g and >=5g, respectively, per 11 apparent volume of the honeycomb carrier. By the coexistence of the catalysts different from each other in the ratio of Rh to Pt, high methane conversion activity and NO reduction activity can be ensured for the resultant ternary catalyst and NO, CO and HC are stably removed at a high rate of removal for a long time.
