Abstract

Domestic
and industrial energy requirements since the beginning of industrial revolution
have been largely met by fossil fuels. This leads to a continuous increase in
the Earth's atmosphere of carbon dioxide and other harmful components. Also
fossil energy resources decreasing day by day and scientists have turned to new
research. In this context alternative energy sources have an important role to
reduce dependence on fossil fuels. One of the alternative energy sources is
biomass and pellet fuel is one of them. In this study, combustion
characteristics of pellet fuel in a model smoke tube boiler at different
loading conditions were investigated numerically. As a Computational Fluid
Dynamic (CFD) program FLUENT package program was used. Calculations were
performed at two dimensional conditions. According to various loading
conditions, temperature and stream function contours, velocity vectors, exhaust
gas temperatures and efficiencies were investigated and results were discussed.
