Heat Recovery Boiler - an overview | ScienceDirect

The steam flow from a heat recovery boiler can usually be increased by the addition of an economizer to preheat the feedwater before it enters the evaporator. The impact of adding an economizer to the evaporator previously analyzed in Fig. 3.1 is shown in Fig. 3.2.The gas temperature leaving the system is reduced substantially and the steam flow is increased approximately 75%.

Steam - Wikipedia

2020-7-2 · Steam is water in the gas phase. It is commonly formed by boiling or evaporating water. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses.. The enthalpy of vaporization is the energy required to turn water into the gaseous form when it increases in volume by 1,700 times
