Boiler Efficiency Improvement - ChemEnggHelp

Oct 07, 2020 · Boiler Efficiency. In coal fired boilers steam generation (kg steam/kg coal) depends on coal GCV (gross calorific value). For higher GCV coal we get more steam generation per kg of coal and vice versa for low GCV coal. In a boiler we can estimate efficiency by two method, first is direct and second is indirect method. Direct Method

Coal fired boiler: How to derive optimum efficiency

Boiler efficiency is based mainly on the quantity of loss suffered by the system. In case of pulverized, high-capacity coal fired boiler, loss amounts to approximately 12-14 percent. 50 percent of losses are governed by different fuel properties such as moisture present in fuel, hydrogen in fuel including ambient air conditions.The remaining 50 percent losses are attributed to dry gas loss and
