This heat supply system (1) is provided with: an exhaust gas economizer (14) for collecting heat from exhaust gas that has been selected in a mutually exclusive manner from exhaust gas of a prime mover (11) which is installed in a ship and provides propulsion to the ship or exhaust gas of an incinerator (12) that burns combustibles produced inside the ship, said combustibles including impurities, etc., separated from fuel oil before consumption by the prime mover (11); a steam-separating drum (15) for separating water vapor from water in a liquid-gas state by using heat collected by the exhaust gas economizer (14); and a compressor (17) for compressing the water vapor separated by the steam-separating drum (15) and raising the temperature thereof. The water vapor compressed by the compressor (17) is supplied to heat-using devices (18). When the ship moves at a normal speed and the load of the prime mover (11) is larger than or equal to a predetermined threshold, the exhaust gas of the prime mover (11) is delivered to the exhaust gas economizer (14). When the ship stops or moves at a very slow speed and the load of the prime mover (11) is less than the predetermined threshold, the exhaust gas of the incinerator (12) is delivered to the exhaust gas economizer (14). |
