PURPOSE:To eliminate the necessity of providing additional hot water heater for raising the temperature of a circulating hot water by arranging a heat accumulator which accumulates therein pressure water heated by the exhaust heat. CONSTITUTION:Pressure water 9 is circulated in pipes 23, 24 by opening switching valves 21, 22 and starting a pump 25, is heated directly by heat exchangers 19, 20 between an auxiliary Diesel engine 17 and a waste oil combustion furnace 18, and is indirectly heated by the thermal energy in a heating coil 10 connected to the exhaust heat section such as a boiler through a pipe 12. When the pressure of the water 9 is lowered due to the use of accumulated heat, a pressure regulating valve 16 detects it and opens it, and heating steam is supplied thereto. Accordingly, the water 9 is raised under pressure, thereby maintaining the prescribed pressure. |
