1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS

1. ENERGY PERFORMANCE ASSESSMENT OF BOILERS Bureau of Energy Efficiency 1 1.1 Introduction Performance of the boiler, like efficiency and evaporation ratio reduces with time, due to poor combustion, heat transfer fouling and poor operation and maintenance. Deterioration of fuel quality and water quality also leads to poor performance of boiler.

Combined Heat and Power | CHP | Cogeneration | Cogen

Combined heat and power (CHP) is the simultaneous cogeneration of electricity and heat. Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40% compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler.. If the fuel for the gas engine is renewable such as biogas
