WebTEi’s innovative Power Generation product line includes a wide variety of Main Steam Condensers, Feedwater Heaters, Moisture Separator Reheaters (MSRs) and Auxiliary Heat Exchangers.From the largest … A feedwater heater is a power plant component used to pre-heat water delivered to a steam generating boiler. Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. This reduces plant operating costs and also helps to avoid thermal shock to the boiler metal when the feedwater is introduced back into the steam cycle. http://www.ecourses.ou.edu/cgi-bin/ebook.cgi?topic=th&chap_sec=10.3&page=theory contesting a will in iowa
