This development is an innovative combined heat and power plant consisting of a steam generator with a steam engine for generating electricity. The system is characterized by a high degree of green fuel flexibility. This means that low-quality combustibles with increased water content can also be burned. This means that wood chips with a water content of up to 35%, harvest waste such as maize cobs or straw can be used as fuel. The fuel heat output is approx. 170 kW and the nominal output (thermal + electrical output) approx. 150 kW.
