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.******

Ceragy是一家在Sherbrooke成立的公司，可根据根据De Sherbrooke大学（UDS）许可的技术制造发动机。 Ceragy Engine有可能通过以低成本的价格与常规燃料和生物燃料一起提供高效分布的功率来减少温室气体排放。高热效率是通过UDS Rim-Rotor Rotary Ramjet发动机（R4E）得出的关键技术来实现的，该技术允许用碳纤维边缘旋转器包裹的高压装载式陶瓷叶片和紧凑的低NONOX低Nox旋转旋转旋转战斗利用浮力驱动的火焰传播的优势。在两阶段的恢复性的布雷顿周期中，使用R4E技术，预计Ceragy Engine的效率为50％，费用低于500美元/kW。与最先进的传统小规模的燃气轮机相比，效率的提高导致燃料消耗减少了30％。**拟议的研究项目的目的是优化缝制的发动机高温组件，以实现与常规燃料和生物燃料的分布式CHP高热效率。基本研究和应用研究将在蓝色发动机的关键新颖元素上进行，以最大化组合温度，即燃烧器，涡轮机和恢复器。调查结果将在三个发动机原型中进行集成和测试。同时，Ceragy将设计用于制造，进行现场测试并在第2至4年内准备制造的发动机，以在5年级推出发动机生产。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，从而招聘和培训许多加拿大高素质的人员，用于设计，测试和组装Ceragy Engine。******************************************************
