Hot gas generator and dosing machine
for drying of gypsum in Stadtoldendorf

Hot gas generator and dosing machine

Multigips brand is found in dry construction as well building with dry gypsum mortar. A hot gas generator including brown coal dust dosage and conveying was supplied for the plant in Stadtoldendorf. This burner is used to heat (bake) the gypsum rock. Crystallisation water is removed from the gypsum rock in this process, and can be reabsorbed when the end product is mixed with water (setting). The burner is operated with an output of 0.8 MW – 4.0 MW (natural gas) or 1.6 MW – 4.0 MW (brown coal dust) for this purpose. The hot gas temperature is in the control range of 600°C–700°C.

Our scope of delivery includes:

1 DN 1300 dosage unit with two supply outlets
1 hot gas generator including measuring and control path
1 measuring and control path for natural gas operation
Control cabinets for the controller, evaluation and control
Visualisation in the control centre and on site

Since the customer had difficulties with the brown coal dust supply to an existing burner in the past, it was integrated into our dosage system. The interface to the brown coal dust supply of this burner was realised as part of the overall order.

Putting the entire system into operation and optimising it, including the integration of the third-party burner, was realised in just 2 weeks.
