According to principles of cogeneration, the Spanner Wood Cogeneration System converts wood chips into biomass electricity and warmth with high efficiency. The systems are run using natural wood chips and provide attractive cost advantages and/or increased power yields according to location and legal conditions. Hundreds of our systems are used in Europe, Asia and North America in agriculture and forestry, hotels, restaurants and heat grids, powered with biomass electricity and warmth from wood gasifier.
The newly developed, compact wood cogeneration systems HV30-V1.1 and HV45-V1.1 make it possible to fit the systems in rooms with a minimum standard ceiling height of 2.50m. Besides heat insulation, all the heat-carrying components are covered with a resistant coating. A more efficient generator is used for the CHP, which further increases the efficiency of the overall system.
With respect to internal values, such as for process leading and its components, this has provided great results for hundreds of operators over a total of several million operating hours: a compact reformer, condensate-free wood gas purification and intelligent, fully-automated process regulation. The performance sizes of 30 kWel or 45 kWel have proved themselves, as these dimensions have proven as particularly good in covering base loads for heating grids. If necessary, several systems can be combined seamlessly.
The heart of the wood cogeneration plant is an efficient, robust combined heat and power system (CHP). The plant consists of an innovative reformer and a CHP, powered by the system of wood gasification.
Depending on the system of wood gasification, the plant generates biomass electricity between 30 and 45 kWel and a total heat power of 80 to 120 kWth. Wood chip consumption is between 30 and 45kg/h equalling consumption of approx. 1kg/h wood chips per kWel electric output, powered by wood gasifier.
