Waste Engergy

Waste treatment usually refers to physical, chemical, biological, physical, and biochemical methods that convert solid waste into a process suitable for transport, storage, use, or disposal. The objective of waste treatment is to detoxify, reduce, and recycle.

The followings are some of the technologies and products:

Combustion in a Rotary Kiln

The combustion in a rotary kiln is suitable for thermal treatments of solid, liquid and paste-like waste.

Typical applications are treatment plants for hospital and hazardous waste, industrial and sewage sludges as well as contaminated soil.

Depending on the application – incineration or gasification – various designs are applied like directly or indirectly fired rotary kilns.

Waste Cutter

The bulky waste cutter is used to cut pieces to an optimal size for delivery to the grate and for uniform combustion. The cutter is fed by an overhead crane system. Afterwards, the cut material falls back into the waste bunker. Due to the design of the outlet chute, the cut materials have a different route to the feeder. This process simplifies the re-feeding of large pieces.

The cutter is controlled by the crane operator and stops when it has reached the end position or when the maximum force is applied. In the second case, the cutting process is repeated automatically.

Based on various knife shapes, the range of applications is extensive. The knives are constructed in such a way that they can be interchanged easily and are re-usable when resharpened

The cutter has a capacity of about 70 m3/h of waste material and is driven by two hydraulic cylinders, which allow for optimal utilization of the shear forces.

The cutter is encased within solid steel casing, protecting all drive parts in order to ensure low wear and outstanding ease of maintenance.

Ash Discharger

The function of an ash discharger is to transport and remove the remaining slag after complete combustion. It also forms the seal between the combustion chamber (low pressure) and the environment outside the incinerator.

The air seal is guaranteed by a water bath, so air and gas leaks are prevented. The correct water level is maintained by a float switch valve.

The ash discharger is a well proven design. The drive is made by two hydraulic cylinders attached to a pusher which transfer the slag out of the water bath. The internal surfaces are lined with changeable wear plates, in order that they can be replaced if necessary, during a routine maintenance period.
