The Province of Manitoba is taking significant steps to reduce emissions resulting from the generation of space heat by legislating the mandatory abandonment of coal and petroleum coke fuels. With the impending absence of coal as a fuel, biomass conversion is being encouraged by the government and can be subsidized with eligible biomass products including agricultural residue, forestry residue and purpose-grown crops. Although government support toward capital costs provides a key incentive for switching to biomass, it is critical that the heat generation from biomass is achieved as efficiently as possible. The overall impact will be two-fold; lower operating costs, which will help make biomass appear especially attractive to those adopting biomass conversion, and a reduction in emissions, which will enhance the original goals set out by the government regarding pollution control. As the importance of biomass furnace conversion is now established, further improvement of this technology is still required. There are several elements which contribute to the overall performance of a biomass heat generator, such as consistent fuel feed rate, combustion chamber design, air injection/distribution, air/fuel ratio, boiler configuration and feedstock flexibility. All these factors have a degree of interdependency which makes further development of this technology challenging. The proposed research uses computational fluid mechanics (CFD) tools to gain far greater insight into the fundamental mechanisms responsible of converting biomass fuel into usable thermal energy. The ultimate goal of this CRD research is to develop advanced knowledge to further improve thermal efficiency and reduce pollutant emissions of grate firing biomass furnace technology. Development of these systems for agricultural residue-based fuels will unleash a major source of revenue for agricultural industry by allowing clean and efficient green energy production. It will increase revenues for farmers by selling agricultural crop residues for fuel instead of burning them in the fields; while at the same time it increases the market share of biomass combustion technology.

曼尼托巴省正在采取重大步骤来减少由太空热量产生的排放，并立法放弃煤炭和石油焦炭燃料。由于即将出现的煤炭作为燃料，政府正在鼓励生物质转换，并可以通过合格的生物量产品进行补贴，包括农业残留物，林业残留物和目的种植的农作物。尽管政府对资本成本的支持为改用生物质提供了关键的激励措施，但至关重要的是，从生物质产生的热量至关重要。总体影响将是两个倍；较低的运营成本将有助于使生物质显得对采用生物质转化的人特别有吸引力，并减少排放，这将增强政府对污染控制的原始目标。 由于现已确定生物质炉转换的重要性，因此仍然需要进一步改进该技术。有几个元素有助于生物量加热器的整体性能，例如一致的燃料进料速率，燃烧室设计，空气注射/分配，空气/燃料比率，锅炉配置和原料弹性。所有这些因素都具有一定程度的相互依存，这使得该技术具有挑战性。 拟议的研究使用计算流体力学（CFD）工具，可以更深入地了解将生物量燃料转化为可用热能的基本机制。这项CRD研究的最终目标是发展高级知识，以进一步提高热效率并减少炉排发射生物质炉技术的污染物排放。开发这些系统用于农业残留物燃料，将通过允许清洁有效的绿色能源生产来释放农业产业的主要收入来源。它将通过出售农作物残留物来增加农民的收入，而不是在田间燃烧它们。同时，它增加了生物质燃烧技术的市场份额。
