    The next process 2-3 takes place in the boiler. The energy balance in the boiler can be expressed as the change in enthalpy of the fluid from the "before" state (compressed liquid) to "after" state (superheated steam): Q in = H 3 − H 2. Where Q in is the heat used by the boiler. This heat is supplied to the boiler from the solar concentrator.

  • Feed water: Why water Treatment is Necessary for Boiler

    The economizer is the section of a boiler used to preheat feedwater before it enters the main boiler system. Preheating the water increases boiler system efficiency. This heat exchanger transfers heat from the stack gases to the incoming feedwater. The economizer is usually located close to the stack gas outlet of the boiler. Get A Quote

    Process Description. Boiler feed water is preheated in a heat exchanger called an economizer before entering the steam drum. The economizer uses hot combustion gases to preheat the boiler feed water in order to minimize the amount of heat lost to the stack. Saturated steam is generated in the risers of the boiler.
