Abstract
A cogenerating recuperated microturbine includes a recuperator, an air compressor and a combustor. The combustor burns a fuel along with the compressed air received from the recuperator to create products of combustion. A turbine generator operates in response to expansion of the products of combustion to generate electricity. The products of combustion then flow through the recuperator to preheat the compressed air. The products of combustion then flow out of the recuperator as an exhaust flow. A heat exchanger is movable into and out of the exhaust flow to selectively heat a fluid in the heat exchanger. The heat exchanger is actuated by a piston-cylinder type actuator that operates under the influence of compressed air selectively bled from the air compressor. The actuator may be a single-acting cylinder used in conjunction with a biasing spring, or may be a double-acting cylinder.
