Thermal utilization
of residues
Oschatz has specially
developed a plant
concept for the paper
industry with its high
energy consumption
Thermal utilization
of biomasses
Plants for optimal
combustion of renewable
materials
Thermal utilization
of solid residues
Oschatz offers plants for
utilization of solid residues
as a complete- or a
component-based solution
Direct fired boiler
systems
Plants for utilization of
gaseous by-products
from chemical processes
• Thermal utilization of resulting paper materials
and paper sludge by using an underfeed stoker
and a downstream turbine
• Conditioning of the low-calorie residues
• Utilization of gas-turbine waste gases as
combustion air for the simultaneous pre-drying of
the residues
• Conversion of the energy from the high-pressure
steam into electrical energy in a steam turbine
• Flue gas cleaning according to the legislation
• Utilization of residues from combustion (slag)
and the flue gas cleaning (gypsum) as reusable
materials
Thermal utilization of the residues in a
power-heat-coupling process
In this process, the residues are thermally utilized
by incineration in a firing and boiler plant.

Process summary:
Power Plant Industry
Fuel range (extract):
Biomasses from farming and forestry as well as
industrial processing contain a great
amount of thermally usable energy.
The use of this energy is a sensible,
environmentally friendly and a CO2-neutral method
of utilization.
