Development of a high-efficiency multifuel small-scale turbo generator for low-cost distributed ground combined heat and power

Ceragy是一家成立于舍布鲁克的公司，以舍布鲁克大学（UdS）授权的技术为基础，制造陶瓷部件发动机。Ceragy发动机具有降低温室气体排放的潜力，可通过传统燃料和生物燃料以低成本提供高效分布式动力。高的热效率是由来自UdS轮缘转子旋转冲压发动机（R4 E）的关键技术实现的，该技术允许高燃烧温度，即压缩加载陶瓷叶片包裹在碳纤维轮缘转子中，以及利用浮力驱动火焰传播的紧凑型低NOx旋转燃烧器。在两级回热布雷顿循环中使用R4 E技术，Ceragy发动机预计将以低于500美元/千瓦的成本实现50%的效率。与用于热电联产（CHP）市场的最先进的传统小型燃气轮机相比，这种效率的提高导致燃料消耗减少30%。 拟议研究项目的目标是优化Ceragy发动机高温部件，以实现传统燃料和生物燃料分布式热电联产的高热效率。将对Ceragy发动机的关键新元件进行基础和应用研究，以最大限度地提高燃烧温度，即燃烧室，涡轮机和回热器。研究结果将在三个发动机原型中进行集成和测试。与此同时，Ceragy将在第2年至第4年设计发动机以进行制造，进行现场测试并准备制造，以便在第5年启动发动机生产。 如果成功，该研究将为Ceragy提供比其他小型分布式发电机组制造商更明显的优势。这项研究还将推动Ceragy成为加拿大（魁北克省Sherbrooke）的世界领先发动机制造商，从而雇用和培训许多加拿大高素质的人员来设计，测试和组装Ceragy发动机。

Ceragy is a company founded in Sherbrooke to manufacture engines with ceramic components based on technologies licensed from the Université de Sherbrooke (UdS). The Ceragy engine has the potential to cut greenhouse gas emissions by offering high-efficiency distributed power at low cost with both conventional fuels and biofuels. High thermal efficiency is enabled by key technologies derived from the UdS Rim-Rotor Rotary Ramjet Engine (R4E) that allows high combustion temperature, namely compression-loaded ceramic blades wrapped in a carbon-fiber rim-rotor and a compact low-NOx rotating combustor taking advantage of buoyancy-driven flame propagation. Using the R4E technology in a two-stage recuperative Brayton cycle, the Ceragy engine is projected to achieve an efficiency of 50 % at a cost below 500 $/kW. This increased efficiency results in a fuel consumption reduction of 30 % when compared to state-of-the-art conventional small-scale gas turbines for the Combined Heat-and-Power (CHP) market. The objective of the proposed research project is to optimize the Ceragy engine high-temperature components to achieve high thermal efficiency for distributed CHP with conventional fuels and biofuels. Fundamental and applied research will be carried on the key novel elements of the Ceragy engine to maximize combustion temperature, namely the combustor, turbine, and recuperator. Findings will be integrated and tested in three engine prototypes. In parallel, Ceragy will design the engine for manufacturing, conduct field tests and prepare manufacturing during years 2 to 4 to launch engine production in year 5. If successful, the research will provide Ceragy with a clear edge over other manufacturers of small-scale distributed power generation units. This research will also propel Ceragy to become a world-leader engine manufacturer here in Canada (Sherbrooke, Québec), thereby hiring and training many Canadian highly-qualified personnel for the design, testing and assembly of the Ceragy engine.
