Thermoeconomic Performance, Exergy, Boiler System & Exergetic Efficiency 1.Introduction A boiler is a device used to convert water to steam. The water to be converted to steam comes from two major sources: (1) Condensed steam returned from the processes. (2) Makeup water.
a reliable steam$ worst, this suggests some managers are oblivious to the opportunities to control steam system operating costs~ However, the optimization ofindustrial steam systems is a worthwhile pursuit that returns real value to the asset owners. In order to achieve this, steam systems will require
flow of steam leaving the boiler drum. Maintaining liquid level in the boiler steam drum is the highest priority. It is critical that the liquid level remain low enough to guarantee that there is adequate disengaging volume above the liquid, and high enough to assure that there is water present in every steam generating tube in the boiler.
H= Enthalpy of steam (Kcal/kg) h= Enthalpy of water (kcal/kg) GCV= Gross calorific value of the fuel. Indirect Efficiency. The indirect efficiency of a boiler is calculated by finding out the individual losses taking place in a boiler and then subtracting the sum from 100%. This method involves finding out the magnitudes of all the measurable ...
