    摘要: Corrosion is avoided by using an external superheater heated by the clean gas exhaust coming from the internal combustion machine (ICM) mixed with pure air, with duct firing to adjust the steam superheating temperature, in the same way the existing natural gas/waste power plant do. The difference in the proposed patent is that the ICM is chosen not to match the steam amount produced in the waste boiler, which is superheated to a corrosion safe temperature say 400 C or less, but just to provide the plant own power consumption. We need to increase this ICM exhaust flow with pure air and use duct firing (11,12) to raise the gas mixture temperature, say between 600 C and 700 C, high enough to superheat the steam in the external superheater (3) to approximately 500 C. If we use pure air at ambient temperature, the amount of natural gas in the duct burners (11,12) will be very high decreasing the natural gas efficiency. To reduce the natural gas consumption in the duct burner (11,12) we use the hot gas leaving the external superheater (3), around 420 C, to preheat the ambient air to say 390 C, in a air/gas heat exchanger (13), before it is mixed with the ICM exhaust, increasing the mixture temperature to a value close to 400 C, reducing drastically the natural gas consumption in the duct firing (11,12).

    摘要: Provided is a reheat boiler in which the imbalance in temperature distribution of the temperature of the combustion gas at the outlet of a reheat furnace is reduced by changing the gas flow pattern in the reheat burner. A reheat boiler (10A) includes a main boiler (106) configured such that main combustion gas generated in combustion in a burner (101) flows from a furnace (102) through a superheater (104) and evaporator tubes (105), a reheat furnace (108) that is disposed on the downstream of the evaporator tubes (105) and produces reheat combustion gas by combustion in a reheat burner (107), and a reheater (109) disposed above the reheat furnace (108). A closing plate (130), serving as a drift preventing portion, is provided at a reheat furnace outlet (120) that connects the reheat furnace (108) and the reheater (109) to form a flow path for the combustion gas and the reheat combustion gas so as to narrow the cross-sectional area of the flow path for the combustion gas.

    摘要: In a heat pump system including a water purifier (1) and an evaporator (2) for evaporating feed-water (10) to produce steam (12), water (11) used for spray cooling is effectively used and productivity of purified water used for the spray cooling is increased.
    Discharged water (21) from the water purifier (1) is supplied to the evaporator (2) when water used for spray cooling is produced by use of the water purifier (1). Otherwise, drain (22) of the evaporator (2) having higher temperature is supplied to the water purifier (1) by using such a fact that in a reverse osmosis membrane type water purifier (1), the higher the temperature of feed-water (10) is, the higher the purified water productivity becomes.
