年内，化石燃料价格的不断上涨不断增加了偏远矿山的运营成本。 在过去二十年里。因此，矿业公司不断寻找机会来削减这些成本。 柴油发电机组排气余热回收利用及现场开采 因此，运营可以提供一个独特的机会。这项技术的发展将导致更低的 运营成本和采矿作业的较小碳足迹。 Cubit Power正在研究新技术，以帮助其矿业客户发电 更高效，并最终降低采矿作业中的发电成本。其中一个 开发这种系统的主要问题是需要相对昂贵和笨重的热交换器来 从排气液中取出热能。Cubit Power及其采矿业客户 对柴油发电机组余热回收的预可行性进行了一年多的审查，但在这方面的研究 这一地区是迫切需要的。麦吉尔的研究人员和Cubit Power的专家认为，使用热量 从热风流废气中回收热的管式机组是解决这一问题的可行方案。 因此，Cubit Power要求麦吉尔大学的研究人员帮助他们进行 对该技术进行了技术经济分析。Cubit Power有兴趣实施这一结果 在远程采矿作业中的项目。 本研究项目探讨了利用热管技术进行回收的技术经济可行性。 柴油发电机组热排气余热。它将研究余热的热物理特性。 采矿用柴油发电机组的流向及各种参数对经济性的影响 回去吧。通过评估可回收余热的数量和价值，本研究将估计 通过回收柴油废气可以获得的经济效益和环境效益。

Escalating price of fossil based fuels has continuously increased the operational costs of remote mines during the last two decades. Therefore, mining companies are constantly looking for opportunities to cut these costs. Recuperating waste heat of the exhaust streams of a diesel generator and using its energy on-site mining operation can provide a unique opportunity as such. The development of this technology will result in lower operational costs and smaller carbon footprint of mining operations. Cubit Power, is working on novel technologies to help its customers in mining industry with generating power more efficiently and ultimately with lowering the cost of power generation in mining operations. One of the major issues with developing such a system is the relatively expensive and bulky heat exchangers required to remove the heat energy from the exhaust fluid. Cubit Power and its clients from mining industry have examined the pre-feasibility of recuperating waste heat of diesel gen-sets for over a year, yet research in this area is urgently required. Researchers at McGill along with experts at Cubit Power believe that the using heat pipe units for heat recovery from hot air stream exhaust gases is a viable solution to resolve this issue. Therefore, Cubit Power has asked researchers at McGill University to help them with conducting the techno-economic analysis of this technology. Cubit Power is interested in implementing the result of this project in remote mining operations. This research project investigates the techno-economic feasibility of using heat pipe technology for recovering waste heat of hot exhaust gases of diesel gen-sets. It will study the thermo-physical characteristics of waste heat streams of diesel gen-sets used in mining operations and effects of various parameters on the economic rate of return. By assessing the amount and the value of the recoverable waste heat, this study will estimate the economic and environmental benefits which can be gained by recovering diesel exhaust streams.
