The next generation steamboilers

Combi waste gas boiler

In the combi waste gas boilers, steam or hot water is produced by using heat recovery from flue gases and/or process gases from gas engines, diesel engines, gas turbines or from other combustion processes.

These boilers can be used in flue gases and/or process gases with a temperature of up to 1250 °C and a flue gases mass flow of approximately 50 kg/s.

The boilers, with a workload that can reach about 50 barg, can be equipped with a burner for bite-heating or fresh air operation.

For greater efficiency, an economiser can be installed, which makes the most of the residual heat in the flue gases. This leads to remarkable improvement in efficiency and significant (cost) savings on fuels.

Combi waste gas boilers can also be equipped with a superheater, allowing a steam temperature of approximately 440 °C to be reached over a wide range.

The combination of gas boilers are very suitable for application in:
