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.
