A validated computer-aided simulation of a two-stage biomass combustion system was used to analyze the effects of biomass moisture and degree of insulation around the gasifier-combustor on its turndown ratio. The size of the gasifier-combustor was also varied to examine its influence combined with other factors described earlier on the turndown ratio and heat loss from the system. The turndown ratio was found to decrease with the increase of biomass moisture. The effect of insulation was more prominent for smaller units than the larger ones. Turndown ratio was found to increase with the increase in thermal resistance. The maximum fraction of heat loss varied between 0.25 and 0.41 for biomass moistures of 0.5 and 0.1, respectively, for any size with any level of insulation. 9 refs., 5 figs., 4 tabs.
