A biomass fuel power generation device

Abstract

The present invention relates to a biomass fuel power generation device. When the device needs to be used for power generation, the biomass fuel can be put into a feeding mechanism, and the biomass fuel is ignited by an ignition component. At the same time, an exhaust fan discharges the exhaust gas through an air outlet, and introduces new air through an air inlet. Then, the flame generated by the biomass fuel heats a heat conducting rod, and then the heat conducting rod transfers the heat to a heat receiving chamber. Then, the heat on the heat receiving chamber is transferred to a temperature equalizing plate through a heat conducting plate, so that the temperature equalizing plate transfers the heat evenly to one side of a thermoelectric power generation sheet. At the same time, a heat dissipating component dissipates the heat from the other side of the thermoelectric power generation sheet. Then, the electric energy generated by the thermoelectric power generation sheet is converted into effective electricity through a booster plate and transmitted to a power receiving body, thereby reducing fuel costs, using biomass fuel for combustion power generation, reducing noise and vibration, and the overall equipment has a simple structure, low cost, and is easy to maintain.
