THE STRUCTURE OF EXHAUST GAS FLOW PASSAGE OF ENGINE IN MICRO COMBINED HEAT AND POWER UNIT

摘要

PURPOSE: An emission structure of an engine outlet at a small heat supply and power generation plant is provided to induce side-stream heat exchange on the side rather than the central part and maximize heat exchange efficiency since exhaust gas is diffused with curvature. CONSTITUTION: An emission structure of an engine outlet at a small heat supply and power generation plant comprises a sterling engine, an auxiliary boiler, an engine head, and an outlet. The engine head discharges exhaust gas heated the sterling engine. The path connects the engine head to a latent heat exchanger. The outlet is formed so that exhaust gas flows from the upper part to the lower part of the latent heat exchanger for heat exchange. A slope inclined to the latent heat exchanger is formed on the upper end of the outlet. A plurality of partitions are installed on the discharge end of the outlet in the length direction of the outlet.
