Combined heat and power plants and decentralised combined heat and power units

Combined heat and power plants generate electricity and heat in a cogeneration process. The cogeneration of heat and power results in a higher fuel utilisation rate than with power plants that solely produce electricity. The heat generated is used for industrial purposes or fed into district heating networks and made available as thermal energy. Depending on the intended mode of operation and the consumer situation, it may be necessary to increase the heating power by additional boilers or to store the heat, which is currently not needed, via thermal buffer storage.

BNA has provided electrical and control equipment for a large number of combined heat and power plants and decentralised combined heat and power units. The range of plants includes decentralised combined heat and power units, steam turbine plants as well as power plants with additional thermal boilers and stores.

BNA has tried and tested solutions for all potential plant combinations, for the control of individual plant parts and whole power plants whether for power- or heat-led mode operation. The company's expertise also includes electrical, instrumentation and control equipment for converter substations as well as the control and monitoring of extended district heating networks with a large number of house service connections.
