Deaerator is one of the open type contact feed water heater used in boiler water treatment. It is the device that is widely used for the removal of oxygen and other dissolved gases from feed water supply to boiler. The presence of dissolved gases like oxygen and carbon-dioxide in water makes the feed …

Ideal Rankine cycle with reheat and open feedwater heater

WebOpen Feedwater Heater. Steam at 350 o C and 650 kPa is mixed with subcooled water at 30 o C and 650 kPa in an open feedwater heater ( FWH) as a way to produce saturated liquid water at the same pressure. Assuming the open FWH is adiabatic, determine the mass flow rate of steam required per kilogram of subcooled liquid water fed to the open … 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.
