220kW agenitor 206 Natural Gas
2G. Technical Specifications agenitor 206 (220 kW) Natural Gas 2G. Combined Heat & Power. agenitor 206_60Hz/480V Picture: symbolic - may deviate from module described Compact CHP module ready for connection, Integrated heat recovery system assembly, mainly consisting of - Gas-Otto-engine from industrial series production - air-cooled, self-excited, brushless synchronous generator mainly consisting of - expansion tank for engine and mixture cooling circuit - exhaust gas heat exchanger integrated in primary cooling water circuit - safety valve in engine, mixture and heating circuit - filling, drain and bleeding valves - oxidizing catalyst integrated in exhaust gas heat exchanger - transfer plate heat exchanger - pumps for engine, mixture and heating circuit - oil reservoir with automatic oil top-up device - 3-way mixing valve for return temperature increase - control cabinet with programmable logi control and operating panel - gas pressure regulation and safety ramp Water and gas connections are equipped with compensators. All water-side connections above the heat recovery assembly are directed upwards. Engine and alternator are linked by a pluggable elastic metal-plastics coupling to compensate radial, axial and angular misalignment and mounted on vibration damping elements on the module base frame. Moreover the module base frame is isolated from the installation surface by anti-oscillation elements. The control cabinet is executed as a separate unit. All regulation and control functions as well as operational controls are integrated. The menu-navigated touch-screen allows to read and adjust all performance and status data. The CHP module is driven by a water-cooled, supercharged Gas-Otto engine designed for stationary continuous operation. The microprocessor-controlled ignition system ensures the optimal adaption of ignition timing and energy to the gas quality (methane no.). Lambda control is carried without lambda probe by using a calculation program, which sets the optimal lambda value for every operational status based on actual power, charging pressure and mixture temperature. The twin-stage mixture cooling with low and high temperature circuit ensures an exceptionally high electrical efficiency as well as an optimal utilization of thermal power of the mixture heat. The oil level control is carried out by a sight glass connected to the oil pan with low oil level indication. A 35 liters oil reservoir ensures automatic oil topping-up between oil changing intervals. The program especially developed by 2G renders possible oil changing intervals > 2.000 operating hours based on the observance of 2G's oil limit values as per technical instruction "2G TA10 AGENITOR Oil" which were determined through specific long term tests.
