Abstract

The combustion gas temperatures in the free board of an internal fluidized-bed furnace using livestock wastes as fuel are experimentally and numerically investigated. Broiler excrements and mixtures of broiler-swine excrements are provided as the fuel. The gas temperatures in the free board are measured at several locations. The exhaust gas temperature is found to be above 1,000 K even for the mixed fuels whose moisture content is 40 wt%.
Three-dimensional combustion simulations based on k-ε techniques are performed in the free board. The calculated gas temperatures in the free board reasonably agree with the experimental ones. The calculations show that the fuel gases are completely burned, maintaining the free board at high temperatures.
