| Compression of bio / landfill gases and other non inert gases |
|
The specific utilization of bio – and landfill gases contributes to reduce the emissions of gases which are dangerous for the climate by generating power. In block-type thermal power stations (BHKW) current is produced in gas motor – generator aggregates. The waste heat arising during combustion is supplied via heat exchangers to a further utilization. Concerning gas exhaust and admission pressure production for block-type thermal power station and flare unit, gas compressors are used. Aerzen gas units are designed for the conveyance and compression of landfill - and biogas as well as natural - or town gas. The blowers can be operated with differential pressures up to 700 resp. 1000 mbar depending on blower size and intake pressure. |
