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.
Highlights
Today, saving energy and studies on the renewable energy resources is gaining importance day by day in the face of declining fossil-based resources
In this study Fluent program was used as Computational Fluid Dynamic (CFD) program and some information was given about the details of the submodels which were used in this program
Temperature and stream function contours, velocity vectors, exhaust gas temperatures and efficiencies were determined for various loading conditions and results were evaluated
Summary
Today, saving energy and studies on the renewable energy resources is gaining importance day by day in the face of declining fossil-based resources. Studies on biomass which is one of the renewable energy sources has gained importance recently. Positive features of biomass fuels in terms of economic and environmental are among the reasons to prefer this renewable source. Boilers can be defined as closed vessels in which combustion occurs and heat from combustion is transferred to a fluid. Boilers are used for heating purposes in houses and in many industries which require energy. The energy efficiency of boilers is dependent on combustion quality and amount of the combustion energy transferred to the fluid. Flue gas emissions dependent on combustion quality, grate type, the amount of the contaminants in the fuel and operating conditions of the combustion system
