Abstract:
Co-firing of biomass with coal in traditional coal-fired power plants represents is a low-cost option for a fast introduction of renewable energy on a large scale. However there are some technical issues associated with biomass co-firing such as fuel flexibility of the plant, combustion efficiency impacts on the ash marketing, fouling of the boilers, etc. The combustion efficiency is highly affected by the physical combustion properties of the biomass and coal, and the residence time in the reactor. Many researchers have used drop tube furnace DTF to study the combustion efficiency of coal and biomass (torrefied biomass), as the main parameters like heating rate and working temperature are close to the actual furnace. In this paper, the detailed description of the setup and the preliminary experimental results with saw dust and coal combustion with air at different particle size, and residence times will be presented.
