OVERVIEW PROJECT SIMPLIFIED SCHEME
Requirement: Complete substitution of coal
combustion through the use of excess biogas and
waste heat from the gas engines.
Solution:
Installation of a biogas -fired thermal oil heater to
replace 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
Possible: Providing the complete Energy Demand
by Biogas!
