Creativity Workshop to Optimise Waste Heat Recovery

为能源密集型行业设计、安装和维护废热发电装置，使企业能够从原本会损失的热量中产生低碳、更便宜的电力。我们的热捕获技术使用热交换器来捕获废热，并使用有机朗肯循环来发电，然后供工业现场使用。这项技术不仅使客户节省了电费，而且还提供了一种满足欧洲能源效率指令严格要求的机制，从而避免了对违规行为的经济处罚。Heatcatcher正在英国东北部Thrislington的Steetley Dolomite旋转白云石石灰窑建设其第一个废热发电项目，预计将于2013年9月投入使用。该系统从窑炉废气中提取4MW的废热，并利用GE热回收解决方案有机朗肯循环技术将其转化为0.5MW的低碳电力。废热利用荷兰格尔茨国际公司制造的4MW热交换器回收。热交换器配有机械操作的刷丝装置，连续运行以避免白云石石灰粉尘积聚在热交换器的管上。Thrislington项目是欧洲石灰和水泥制造商将余热转化为电力项目的大型销售管道中的第一个。尽管这似乎是一个非常明确的商业案例，但行业仍然担心工业过程中断的风险，以及系统将废热转化为电能的效率，因为无效的传热将导致捕获的废热减少，发电量减少。Heatcatcher认识到，围绕热交换器技术开发知识产权是其在该领域竞争优势的关键。因此，捕热器希望开发创新的想法来解决与热交换器相关的以下一个或多个问题：制造，安装和持续维护的成本确保良好的热传递在存在高水平灰尘时避免积聚/堵塞减少背压阻力耐颗粒磨损耐腐蚀

Heatcatcher designs, installs and maintains Waste Heat to Power installations for energy intensive industries allowing companies to generate low carbon, cheaper electricity from heat that would otherwise be lost.Our heat capture technology uses a heat exchanger to capture waste heat and an Organic Rankine Cycle to generate electricity which that then be used by the industrial site. The technology allows customers to not only save on the cost of electricity but also provides one of the mechanisms of meeting the strict requirements of the European Energy Efficiency Directive and hence avoids financial penalties for non-compliance.Heatcatcher is building its first waste heat to power project at Steetley Dolomite’s rotary dolomitic lime kiln at Thrislington in the North East of England and is due for commissioning in September 2013. The system extracts 4MW of waste heat from the exhaust of the kiln and converts it to 0.5MW of low carbon electricity using GE Heat Recovery Solutions Organic Rankine Cycle technology. The exhaust heat is recovered using a 4MW heat exchanger built by Guertz International in Holland. The heat exchanger is fitted with a mechanically operated wire brushing device, continuously operating to avoid the build-up of dolomitic lime dust on the tubes of the heat exchanger. The Thrislington project is the first of a large sales pipeline of waste heat to power projects for manufacturers of lime and cement across Europe.Despite what may appear to be a very clear business case, industry is concerned about the risk of disruption to an industrial process and also about the efficiency of conversion of waste heat to electricity of the system since ineffective heat transfer will result in less heat waste heat being captured and less electricity being generated. Heatcatcher recognises that developing intellectual property around heat exchanger technology is the key to its competitive advantage in the sector.Heatcatcher would, therefore, like to develop innovative ideas to solve one or more of the following issues that relate to the heat exchanger:Cost of manufacturing, installation and on-going maintenanceEnsuring good heat transferThe avoidance of build-up/clogging when high levels of dust are presentReducing back pressure resistance Resistance to particle abrasionResistance to corrosion
