Engineering from the external provider/SBS warehouse designed:
Cement production: Secondary fuel from waste products reduce energy costs
Bad Soden, 13 May 2004.
DEUNA Zement GmbH, Deuna/Thuringia, has with the support of TRIPLAN AG (Merseburg branch) engineering specialists, designed and installed a warehouse for liquid secondary fuel. The plant successfully began operation in March with the unloading of the first tanker train.
In addition to the usual primary fuels, DEUNA Zement GmbH (a subsidiary of the Dyckerhoff Group) now uses liquid to high-viscosity secondary fuels (SBS = Sekundärbrennstoffe) from waste products to product clinker and cement. This saves the company considerable energy costs. To guarantee security of supply DEUNA had to invest in an appropriately dimensioned secondary fuel warehouse.
The engineering and IT provider TRIPLAN AG (Merseburg branch) was hired as general contractor initially for basic engineering and finally for detail engineering for the construction, electricity and MSR technology trades. The provider is also supposed to support the client in purchasing all goods and services, TRIPLAN Merseburg also provided manufacturing control services and supported the start-up process. "Total responsibility enabled us to provide optimum coordination of the construction process," says the TRIPLAN branch manager Ottomar Berndörfler.
What were the critical points when planning the secondary fuel warehouse? The main problem was the large amount of substance data and contamination of the SBS with sediment, organic compounds etc. The fuel to be stored is graded according to Hazardous Material Ordinance (Gefahrstoffverordnung = GefStoffV) 2.2.1 as combustible liquids categorised as ‚flammable‘, ‚slightly flammable‘ or ‚highly flammable‘ and also as water-hazardous liquids of hazardous classes 1 to 3.
The liquid secondary fuels are stored in three 100 m independent storage tanks of the same design. The tank provided for the high-viscosity media has an internal electrical heat register. To prevent sedimentation all storage tanks are equipped with agitators.
The burner is supplied by pumps and pipes installed on a gantry direct out of the storage tanks. Using a front-end heat exchanger the high-viscosity liquids can be heated and the viscosity then set at the appropriate level for the burner.
"This concept that we have implemented together also enables the operator to adjust firing to the needs of the process at any time without increasing the use of cost-intensive primary fuels (Primärbrennstoffe = PBS)," explained Berndörfler about a feature of the installed technology.
