Combustion furnaces

 The heart of every plant is of course the combustion chamber, with its grate and combustion system philosophy.

One burner system for the main combustion chamber and one burner system for the afterburner chamber.

Burner test

The afterburner chamber is divided into two chambers.

Depending on the setting, the combustion chamber temperature is 850 - 950 °C in the main combustion chamber and 950 - 1150 °C in the afterburner chambers.

The firing temperatures are automatically controlled according to local specifications.

An emergency system (pressure and temperature dependent) is available.

We took a closer look at these problems and created a new type of combustion grate that is easy to maintain and favourable in its manufacture and replacement, as combustion gratings are wearing parts.

Ventilation is provided by one or more combustion air fans, the control of which is regulated by corresponding oxygen measurements to ensure sufficient oxygen enrichment and thus complete combustion.

The ash is removed manually via 3 large ash removal doors or optionally via an automatic wet ash removal system. 

Each plant is designed to meet the specific requirements and of course the highest environmental standards. 

We have a wide range of solutions available for this purpose.

Filter systems (bag filter or ceramic filter systems),

Suction and fresh air blower,

Sensors and control systems,

Conveyor belts,

Exhaust gas monitoring system,

and other plant components,

partly included, partly optional, depending on the individual configuration of a plant.
