Modelling of an Improved Biomass Cook Stove for Rural Application

Abstract

AbstractBiomass fuel is essential for both domestic and industrial heating. Biomass is an efficient alternative to our energy crisis now. Normally, harmful pollutants are released during inefficient combustion of biomass due to the poor design of the cook stove in many rural areas. The daily energy crisis in the rural area may be overcome by employing biomass as a cost-effective alternative source of thermal energy and the proper design of cook stove. The initial stage of the work involves modelling of various heat losses from the combustion chamber as well as the temperature variations in different sections of the combustion zone of an improved cook stove. The water boiling test (WBT) is an important tool for evaluating a biomass cook stove's performance. Water boiling tests can be used to figure out the rate of emissions and the efficiency of the cook stove. The numerical analysis helps to investigate the various chemical reactions on various stages that occur inside the biomass cook stoves. In order to increase the overall performance and efficiency and less amount of pollutant, the present study was undertaken. AutoCAD and ANSYS software were used for the design and simulate of the project. The highest thermal efficiency of the present model was estimated as 44.8%, and the lowest efficiency was 23.2% for different fuel bed conditions and firepowers. This present design was compared with the available improved biomass cook stove, and it showed better overall thermal efficiency compared to the previously available designs.KeywordsBiomassCook stoveOverall efficiencyPerformanceDesign
