| Abstract | Small-scale downdraft biomass gasification is a promising technology for off-grid combined heat and power generation utilizing Canada’s vast biomass resources. As small-scale gasifiers are currently emerging into the Canadian market, the current study investigates the required feedstock characteristics for stable operation using Canadian softwood, along with the quality of the biochar produced as a byproduct. It was found that reducing feedstock moisture from 20 to 9% increased overall system efficiency from 8.2 to 12%. Equilibrium simulations were utilized to evaluate the deviation from ideal conversion when using feedstock outside the gasifier feedstock specifications. These showed the gasifier was operating close to equilibrium, with the lower heating value of the actual producer gas deviating by an average of 9% from simulated results. This study provides a novel methodology for the quantification of reliability and efficiency of these systems which can be used to evaluate the economic benefit of these systems in Canada. |
