By fixing the position of the three-way valve and the water flow through the pump, the inlet and outlet water temperature are defined when testing the heat exchanger. Important figures during these tests were: • Heat exchange based on a 70/90 °C water system • Back pressure on the Capstone microturbine In view of the performance and the compactness of the heat exchanger prototype, one prototype of the compact heat exchanger with extendable heat exchanging area was made of high grade material in view of the demand of a high life span. Based on prototype 1, a design was made for a second prototype. To improve the heat exchange area, flue gas and water flow, a second prototype was built (see Figure 2). Figure 2 Prototype 2 of compact heat exchanger Test results for this prototype 2 on a Capstone 60 kWe microturbine are: • Heat exchange to water phase: 118 kWth (based on 70/90 °C water system) • Approach temperature of 5 or 7 °C, depending on in coming flue gas temperature (317 and 341 °C respectively) • Maximum flue gas backpressure of 14.5 mbar. Finally, the improvement of the second prototype led to a commercial version of the heat exchanger with the following properties: • Cheap and simple design • High grade stainless steel with respect to corrosion by e.g. sulphur containing components in flue gases of the microturbine • Mounted on the exhaust of the microturbine • Small footprint, dimensions: H * W * D = 24.5 * 17.7 * 14.2” (63 * 45 * 36 cm) • Proven technology • Approach temperature of max. 5 °C, based on 70/90 °C water system: o Proven thermal capacity on top of a C60 microturbine at full load: > 118 kWth (overall efficiency: > 83%)PDF Image | DEMONSTRATION OF CAPSTONE MICROTURBINES INCLUDING HIGH EFFICIENCY HEAT EXCHANGER, GAS SAFEGUARD MODULE AND NATURAL GAS COMPRESSOR, DEVELOPED BY GASUNIE ENGINEERING & TECHNOLOGY
