An open heat exchanger is one in which extracted steam is allowed to mix with the feedwater. This kind of heater will normally require a feed pump at both the feed inlet and outlet since the pressure in the heater is between the boiler pressure and the condenser pressure. Ver mais 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 … Ver mais A widely use Code for the procedures, direction, and guidance for determining the thermo-hydraulic performance of a closed feedwater heater is the ASME PTC 12.1 Feedwater Heater … Ver mais The American Society of Mechanical Engineers (ASME), publishes the following Code: • PTC … Ver mais The energy used to heat the feedwater is usually derived from steam extracted between the stages of the steam turbine. Therefore, the steam that would be used to perform … Ver mais An economizer serves a similar purpose to a feedwater heater, but is technically different as it does not use cycle steam for heating. In fossil … Ver mais • Fossil fuel power plant • Thermal power plant Ver mais • Power plant diagram • High pressure feedwater heaters Ver mais WebDiscussion: Thus we find that the open feedwater heater did in fact raise the efficiency from 40% to 42%. This may not seem like a significant amount, however all the basic components were already in place, since without a de-aerator the dissolved oxygen and carbon dioxide in the feedwater will cause serious corrosion damage in the boiler.
