Carbotechnik products for drying gypsum stone in Stadtoldendorf

VG-Orth GmbH is a company with over 125 years of experience in industrial gypsum production. Its successful Multigips brand is used in both drywall construction and in construction projects involving gypsum dry mortars. A hot gas generator, including lignite powder dosing and conveying systems, was delivered to the plant in Stadtoldendorf. This burner is used to heat (calcine) gypsum rock. During this process, crystal water is removed from the gypsum rock, which can be reabsorbed when the final product is mixed with water (setting). For this purpose, the burner is operated at a capacity of 0.8 MW – 4.0 MW (natural gas) or 1.6 MW – 4.0 MW (lignite powder). The hot gas temperature typically ranges from 600 °C to 700 °C.

Our scope of supply includes

– 1 DN 1300 dosing unit,
– 1 DN 500 top-mounted filter,
– 1 hot gas generator including measurement and control system,
– 1 measurement and control system for natural gas operation,
– Control cabinets for control, regulation, and evaluation,
– visualization in the control room and on-site

In addition, an existing burner was integrated into our metering system. The interface for the BKS supply to this burner was implemented as part of the overall contract.

Commissioning and optimization of the entire plant were completed in just 2 weeks.
