Creativity Workshop to Optimise Waste Heat Recovery

热捕集器为能源密集型行业设计、安装和维护废热发电装置，使公司能够从原本会损失的热量中产生低碳、更便宜的电力。我们的热捕集技术使用热交换器捕获废热，并使用有机朗肯循环发电，然后供工业现场使用。该技术不仅可以让客户节省电力成本，而且还提供了满足欧洲能源效率指令严格要求的机制之一，从而避免了对非Heatcatcher正在英格兰东北部Thrislington的Steetley Dolomite旋转煅烧石灰窑建造其第一个废热发电项目，并将于9月投入使用2013.该系统从窑炉的废气中提取4 MW的废热，并使用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Guertz国际公司建造的4 MW热交换器进行回收。热交换器配有机械操作的钢丝刷装置，连续操作以避免在热交换器的管道上积聚石灰粉尘。Thrislington项目是欧洲石灰和水泥制造商大型余热发电项目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，工业界关心的是工业过程中断的风险，并且还关心系统的废热到电的转换效率，被捕获，产生的电力更少。Heatcatcher认识到，围绕换热器技术开发知识产权是其在该行业竞争优势的关键。因此，Heatcatcher希望开发创新理念，以解决与换热器相关的以下一个或多个问题：制造、安装和持续维护成本确保良好的传热避免高粉尘含量时的积聚/堵塞降低背压阻力抗颗粒磨损耐腐蚀

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
