Industries improve their efficiency with steam from food waste
The shown steam generator unit is installed at a waste food treatment plant in the UK.
The steam generator recovers the exhaust gas heat of two 1,5 MWel engines. The exhaust gas flows through two totally separated exhaust gas paths. About 570 kWth of exhaust gas heat is used to produce steam, which is supplied to an industrial complex next to the waste food treatment plant which is using the provided steam for their processes.
If the steam is not needed on site, it will be condensed by using a steam condenser which is also part of the APROVIS scope of supply. In this process heating water is generated. The complete steam generator and condenser unit was delivered as containerized version to minimize installation expenses and time. Furthermore no investments for buildings were necessary.
The installation also has an APROVIS FriConPlus for drying the biogas which leaves the fermentation process at 100% relative humidity. The gas is cooled and reheated inside the FriConPlus. Like this the relative humidity can be reduced to around 40%. The FriConPlus is an important part of the gas treatment system, which ensures high efficiency and high reliability of the whole plant.
