Reliability Modeling and Analysis of Biomass Boilers under the Extreme Operating Conditions in Northern Communities

该合作项目旨在提高生物质锅炉的运行效率，并通过在北方社区应用的背景下制定基于基准可用性的维护计划来延长其服务连续性。我们估计了一系列生物质锅炉及其部件的可靠性函数。在这样做的过程中，通过根据部件对锅炉可用性的影响来确定部件的优先顺序，从而减少过度维护，从而最大限度地减少维护成本和频率。这一方法将提高生物质锅炉的运行效率，并通过制定基于可用性的维护计划来延长其服务连续性。这反映了这样一个事实，即在加拿大北部(漫长而严酷的)冬季提供暖气和热水是生物质锅炉的一项关键操作要求。

Biomass is well positioned to assume a major share of energy sources for heating purposes in northern Canada.This partnership project aims at improving the operational efficiency of biomass boilers and extending theirservice continuity by developing a benchmark availability-based maintenance plan in the context of northerncommunity applications. We estimate the reliability functions of a range of biomass boilers and theircomponents. In doing so, the cost and frequency of maintenance will be minimized by reducing overmaintenance through prioritization of the components according to their impact on availability of boilers. Thismethodology will improve the operational efficiency of biomass boilers and extend their service continuity bydeveloping an availability-based maintenance plan. This is reflecting the fact that the availability of heat andhot water during (long and severe) winter seasons in northern Canada is a critical operational requirement forbiomass boilers.
