摘要： PROBLEM TO BE SOLVED: To increase vapor latent heat to be recovered in combined cycle or melting furnace and to utilize it effectively by throwing masses or fine particles of ice into exhaust gas and condensing vapor in the exhaust gas around the ice or the melted water utilizing the latent heat at the time of melting ice. SOLUTION: Refrigerant compressed adiabatically by a compressor 4 is cooled and liquefied by a condenser 3 and then expanded adiabatically by a pressure reducing mechanism 5 to produce cryogenic refrigerant. The cryogenic refrigerant is introduced to an evaporator 6 in order to cool it and then returned through a pipe 8 back to the compressor 4. When water is fed to the outer surface of the evaporator 6, the water is frozen and the ice thus produced is scraped and thrown into a hopper 11 and then fed to a duct 10 through a rotary valve 15. The ice 12 is heated with exhaust gas 300 to produce water 13 and the vapor in the exhaust gas 300 is condensed with the latent heat around the ice 12 or the water 13. The water 13 is stored in a water collector 106 comprising a pit 14 and then fed to a water tank 18 by driving a pump 17 and utilized effectively.

摘要： PURPOSE:To improve heat efficiency, by having exhaust from a steam power engine subjected to isobaric cooling by means of a cooler, and, for condensation, allowing a part of a pneumato-hydro mixture under condensation to be subjected to adiabatic compression to a steam power engine inlet pressure by means of a compressor, before introduced to the inlet of the steam power engine. CONSTITUTION:A steam fluid 2 subjected to adiabatic expansion within a steam power engine is introduced into a steam condenser so as to be completely cooled into condensation 3, while a pneumato-hydro mixture 2C of a dryness 0.7-1 is introduced into a compressor and subjected to adiabatic compression so as to be changed into a condition 1C. Further, the pneumato-hydro mixture in said condition 1C is subjected to isobaric heating to be turned into a heating steam 1, and said heating steam 1 is caused to be introduced into the steam power engine. The aforesaid constitution will lead to improved heat efficiency by several to scores of percentage points, compared with a conventional steam cycle.

摘要： PURPOSE:To greatly enhance the thermal efficiency of a steam powr plant as a whole, by performing the turbine drive (speed control) of auxiliary machinery to save the motive power of the plant, and by recovering the waste latent heat of an auxiliary machinery drive turbine, which would be conventionally abandoned into cooling water. CONSTITUTION:A part of the condensate at the outlet port of a condensate pump 3 is returned to a condensate line (outlet port of a second heater 6) through a boosting pump 28 to recover heat to diminish the quantity of condensate which is sent to heaters 4, 6. As a result, the quantity of bled steam to be consumed to heat the condensate is curtailed so that the quantity of steam for generating electricity can be increased. The thermal efficiency is thus improved. Exhaust gas, which has a temperature of about 140 deg.C and whose pressure is raised through a dust collector 16, an induced draft fan 17 and a pressure-raising fan 18, heats a condensate having a temperature of about 35 deg.C, to about 120 deg.C in a low-level economizer 30. The heat of the exhaust gas is thus recovered into the condensate line. The exhaust gas of about 40 deg.C in a desulfurizer 20 is heated to an anti-white-fuming temperature (about 95 deg.C) by a steam heater 31 and then released into the atmosphere. The waste energy (latent heat in the main) of an induced draft fan drive turbine is thus utilized to heat the exhaust gas.

摘要： PURPOSE:To improve the thermal efficiency of the titled engine by a method wherein overheated steam extracted from steam turbines is cooled by heating feed water and the resultant cooled steam is compressed by a steam compressor so as to be combined with the cycle of the conventional engine. CONSTITUTION:The overheated steam in a condition 8 which is extracted from steam turbines is cooled by heating feed water, the resultant cooled steam is compressed by a steam compressor R5 and combined with the conventional regeneration cycle of 1 7 9 10 1. In operation, a circulation pump R7 is rotated and an evaporating water pipe R8 is heated so as to generate from an operating fluid in a boiler R6 high pressure steam at a flow rate in a condition 5. The high pressure steam thus generated is then heated by a heater R9 to produce the overheated steam with which the steam turbines R11-R13 are rotated and the exhaust steam from the turbines is condensed by a condenser R15 to thereby obtain condensed water in a condition 1.
