主权项

1. A cogeneration apparatus for generating hot water from water by use of waste heat of a prime mover, the apparatus comprising:
an apparatus casing; an airtight chamber provided within the apparatus casing and constructed to prevent exhaust gas of the prime mover from flowing out from the airtight chamber; a heat exchanger disposed within the airtight chamber, the heat exchanger communicating with the prime mover for allowing the exhaust gas to flow through the heat exchanger; a water flow path communicating with an outside of the apparatus casing and the heat exchanger for introducing the water from the outside of the apparatus casing into the heat exchanger to generate the hot water due to heat exchange between the water and the exhaust gas in the heat exchanger, and directing the generated hot water out of the apparatus casing; and a relief valve provided in the water flow path within the airtight chamber and constructed to discharge the exhaust gas, contained in the hot water flowing in the water flow path, to the airtight chamber.
