<p>The present invention relates to a heat supply apparatus that generates medium temperature hot water through heat exchange using steam discharged from a boiler or the like. The present invention includes: a main heat exchanger that generates medium temperature hot water through heat exchange between the steam discharged from the boiler and water recovered from a unit where heat is used; and a pre-heating heat exchanger that pre-heats the water recovered from the unit where the heat is used before the water is supplied to the main heat exchanger. A steam discharge line for steam discharge is connected to the boiler. A distributor is disposed in the steam discharge line. TAhe distributor are connected to a first steam supply line that supplies a part of the steam to the main heat exchanger and a second steam supply line that supplies the rest of the steam to a turbine.</p> |
