COVER ASSEMBLY FOR FORMING EXHAUST GAS FLOW PASSAGE OF SUPPLEMENTARY BOILER IN MICRO COMBINED HEAT AND POWER UNIT

摘要

PURPOSE: A cover assembly for forming an auxiliary-boiler outlet of a small steam supply and power generation plant is provided to extend lifespan since an outlet is formed from a ceramic insulating material like a cover, so corrosion potential does not occur due to condensed water. CONSTITUTION: A cover assembly for forming an auxiliary-boiler outlet of a small steam supply and power generation plant comprises a sterling engine, an auxiliary boiler, and an engine head, and an outlet(246). The engine head discharges exhaust gas heated the sterling engine. The outlet 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. The latent heat exchanger is installed on the cover. The outlet is integrally formed in the cover.
