OVERVIEW PROJECT SIMPLIFIED SCHEME

Requirement: Complete substitution of coal combustion through the use of excess biogas and waste heat from the gas engines.

Solution: • Significantly reduced power consumption by highly

efficient process heating plant.

• Installation of a biogas -fired thermal oil heater toreplace the existing high-temperature heaters.

• Installation of an additional low-temperature air preheater with associated low-temperature thermal oil circuit. The engine waste heat can be optimally utilized in this manner to pre-heat the process air

Result: The amortization is taken place by the saved fuel costs in less than 12 months

Optimized Energy Efficiency of Agricultural Production Plants, for Example Tapioka.
