Design and modifications of boiler mounting device in Asmara brewery factory

Abstract

Energy and environment are closely related and important issues in the present all over world. Present industrial and others organization thought the unique of energy utilization and diverse source reviles such as coal, oil, gas, nuclear, hydropower, solar, wind and biofuel. The Non-renewable energy sources are being limited in this world and energy conservation is one of growing need nowadays. The major issues in the world’s energy consumption are getting used in boilers. Thus, this energy used has to be wisely consumed with great efficiency in industries. Boilers are considered as an important and an expensive property in many industries. In addition to initial cost, boilers have high operational and maintenance cost in order to secure production in safe and acceptable working conditions. In this study concerned with an energy saving, economic and environmental analysis of the fire tube boiler in ASMARA BREWERY. In this project, we concentrated on the improvement of boiler efficiency by recovering a portion of heat content of the flue gas. This is possible due to the most dominant device which is the economizer. The preexisting boiler was designed without an economizer. The present modification involved about the design of economizer in the boiler to reduce fuel consumption and thermal shock. Furthermore, in this type of boiler attain higher efficiency and little enhancement in the efficiency of the boiler will save an outsized amount of fuel and also help to reduce CO2 emission.
