PURPOSE:To greatly increase the volume of steam generated by the heat of exhaust gas from a main engine, by recovering heat by means of a low pressure side gas-water separator and a vacuum drain cooler in addition to heat-recovery by means of a three-stage pressure type exhaust gas economizer system. CONSTITUTION:High, middle and low pressure side evaporating pipes 5 through 7 are disposed in an exhaust gas discharge pipe 1 from a main engine 2. High temperature cooling water from the cylinder head section 2a of the main engine 2 is led into a low pressure side gas-air separator 14 in order to recover heat. Steam drain discharged from a general steam consumption installation 44 is led into a drain cooler 56 to increase the coefficient of utilization, and as well is cooled within the drain cooler 56 by condensate from the steam turbine 47. With this arrangement, the amount of steam generated by the heat of exhaust gas from the main engine is greatly increased so that fuel may be saved. |
