Use the heat in exhaust air economically

You can use the exhaust air from microturbine CHP plants for drying processes directly, without expensive or complicated intermediate steps. Due to the almost complete combustion of the gas, the exhaust air of microturbine CHP plants contains only small fractions of carbon monoxide and formaldehyde. In addition, the exhaust air still contains a residual oxygen content of around 18 %.

Digested residues (digestate), paper, grain, gravel, clay, sewage sludge and much more - except food - can be easily dried with microturbines at temperatures up to 309 °C without a downstream catalyst. By directly using the waste heat for drying, microturbines are particularly economical to operate. The overall efficiency of a microturbine CHP plant is 94 % and is maintained over a large scope, even within the partial load range.

Under the amendment to the German renewable energy law (EEG), in 2012 biogas plant operators will receive a remuneration for heat utilisation of at least 60 %. A requirement, which our microturbine CHP plants definitely fulfil.
