PDF 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.

Fluidized Bed Combustion FBC Boiler - Boilersinfo

" (FBC) Fluidized bed combustion is a combustion technology used to burn solid fuels in steam boilers." In Fluidized Bed Combustion Boiler technology When air or gas is passed through an inert bed of solid particles such as sand supported on a fine mesh or grid, the air initially will seek a path of least resistance and pass upward through the sand.

Design methodology of heat recovery steam generator in

Heat transfer is dependent on the mass flow of hot gases, mass flow of water or steam, temperature difference and surface area. A single-pressure HRSG can recover heat up to a specific level. If more heat is to be recovered, then the area of the heat exchanger increases, which soon becomes economically unfeasible.

Heat Exchanger - Real World Physics Problems

Note that a counterflow heat exchanger is more efficient than a parallel flow heat exchanger. It takes a smaller heat transfer surface area A s to achieve the same heat transfer rate q as a parallel flow heat exchanger, with all else being equal. But despite this there may be advantages to using a parallel flow heat exchanger instead of a
