摘要： A feedwater heater (14) in a heat recovery steam generator (A,B) lies within a flow of hot exhaust gas. The feedwater heater (14) converts subcooled feedwater into saturated feedwater water, the temperature of which is only lightly above the acid dew point temperature of the exhaust gas so that corrosive acids do not condense on coils (18) of the feedwater heater (14). Yet the temperature of the saturated feedwater lies significantly below the temperature of the exhaust gas at the coils (18), so that the coils (18) operate efficiently and require minimal surface area. Pumps (26, 28, 30) elevate the pressure of the saturated feedwater and direct it into an economizer (64, 90) where, owing to the increase in pressure, the water is again subcooled. The economizer (64, 90) elevates the temperature still further and delivers the higher pressure feedwater to evaporators (34, 70, 78) that convert it into saturated steam that flows on to the superheaters (50, 78, 84). Higher pressure pegging stem admitted to the feedwater heater (14) controls the pressure—and temperature—of saturated steam and water in the feedwater heater (14).
摘要翻译：热回收蒸汽发生器（A，B）中的给水加热器（14）位于热废气流中。给水加热器（14）将过冷的给水转化成饱和给水水，其温度仅轻微高于废气的酸露点温度，使得腐蚀性酸不会在给水加热器（14）的线圈（18）上冷凝，。然而，饱和给水的温度明显低于线圈（18）处的废气温度，使得线圈（18）有效地工作并且需要最小的表面积。泵（26,28,30）提升饱和给水的压力并将其引导到节能器（64,90）中，其中由于压力的增加，水再次被过冷。节能器（64,90）进一步升高温度，并将较高压力的给水输送到蒸发器（34,70,78），蒸发器将其转化成饱和的蒸汽，其流过过热器（50,78,84）。进给给水加热器（14）中的较高压力的栓钉控制给水加热器（14）中的饱和蒸汽和水的压力和温度。

摘要： A feedwater heater for a steam generator or heat recovery boiler or waste heat boiler through which hot gases pass includes two sections which are located side by side so that the temperature of the hot gases at the upstream face of each section is essentially the same. The feedwater flows through a heat exchanger before entering the first section, and here it is heated by water flowing from the upstream face of the first section to the downstream face of the second section. The arrangement is such that all tubes in the two sections remain above the dew point of the hot gases, so that water does not condense on the tubes and unite with oxides of sulfur to form sulfuric acid which will corrode the tubes, yet substantial temperature differentials exist between the water in the sections and hot gases as the gases pass through the sections.
