Delivery

In the delivery area, newly arrived waste is weighed, registered and tipped into the refuse pit, where it is mixed and temporarily stored. In terms of size, the refuse pit is designed to hold sufficient fuel for several days of c... More

Service/Technology Image

Feeder

A crane system lifts the waste from the refuse pit and transports it to the feed chute, which consists of a hopper and a chute shaft. The feed rams push the waste from the feed chute onto the grate. The waste column in the chute s... More

Combustion system

The combustion system, consisting of the grate system and furnace, forms the technological focal point of waste-to-energy plants. Various combustion concepts are available to achieve the best possible burnout at low flue gas flows... More

Reverse-acting grate Vario

The combustion of residual waste is a complex process since the composition, heating value and ash content of the fuel is very heterogeneous. As a result, operators of waste-to energy plants face an enormous challenge: Given a ser... More

Service/Technology Image

Horizontal grate

The MARTIN horizontal grate consists of alternating rows of fixed and moving grate bars. Neighbouring moving grate bar rows move in opposite directions, therefore effectively transporting and mixing the fuel to ensure good burnout... More

Flue gas recirculation

As an alternative to secondary air systems using only fresh air, we also offer flue gas recirculation. This process involves extracting flue gases downstream of the dedusting unit and returning them to the furnace to replace some ... More

SYNCOM process

The limit values for emissions applicable to waste-to-energy plants are more stringent than those applying to any other type of industrial plant. Irrespective of this, the trend to further minimize pollutant emissions is contin... More

Service/Technology Image

SYNCOM-Plus process

Landfilling of untreated residual waste is prohibited in many countries. Combustion has become a common method of treatment for such waste. The political goal of 'landfill-free' waste management has also been promulgated, that is ... More

Service/Technology Image

Discharger

For decades, the MARTIN discharger has proven to be a compact, reliable and cost-effective device. The hot, burnt-out bottom ash is transported from the grate end to the discharger's water bath where complete quenching occurs. The... More

SNCR process

In waste-to-energy plants, the nitrogen content and chemical compounds of the waste are the crucial factors for the formation of nitrogen oxides (NOx) in the flue gas. By means of flue gas recirculation, catalytic denitrification ... More

Service/Technology Image

Energy recovery

Thermal treatment of waste releases energy that can be employed to generate electricity, heat for district heating purposes or process steam, and various combinations of all three. The first step is to generate steam in suitable b... More

Service/Technology Image

Flue gas cleaning system

During combustion, pollutants are formed or, if they are contained in the waste, are released and pass into the flue gases. These pollutants must be removed before the flue gas can safely be allowed to enter the atmosphere. A flue... More

MICC system

Modern power plants are operated fully automatically and hence facilitate the minimization of the extent to which they require manual intervention. All processes are therefore designed thus that normal operation is maintained in a... More

Dry discharge system

In times of diminishing resources and increased environmental awareness, the bottom ash that remains on the grate after combustion should be recycled, in particular with respect to the ferrous and non-ferrous metals contained ther... More
