Abstract:
Boilers are vital components in any industry. Usually, a fluid like water is used to generate high pressure steam for the heating purposes. In a food industry, there is a large requirement of this high-pressure steam. Boiler is one of the main equipment that requires high fuel consumption. Therefore, fuel optimization is very significant for efficient processing. The aim of this project is to optimize fuel consumption in saturated steam boiler. For this purpose preheated air is fed to the furnace and excess air is controlled to enhance the boiler efficiency by minimizing the losses, thus leading to fuel optimization. Moreover, the make-up water is also preheated in condensing economizer to reduce the energy requirements in the boiler.
Saturated steam boilers use heat from the furnace to generate steam. Major components of the fired tube boiler are economizer i.e. a tubular type heat exchanger which preheats the BFW to economize the process. A furnace with convective and radiative zones, in which the combustion takes place. Economy is the most important factor in the industry so fuel consumption is optimized by certain methods which is the main focus of this project.
