A comparison of the capital, consumption and operating costs for the centralised and decentralised generation variants showed that the centralised variant (partial renewal) has significantly lower annual costs than the decentralised concepts. The cost difference is around €500,000 per year.read more

The investigation created the prerequisites for a heating system dimensioned according to requirements. For example, the required heat output of the new system could be reduced from 6,000 to 4,000 kW initially. Compared to the existing heat supply contract, annual savings of more than 100,000 € were possible.read more
An economic comparison of different heat generation technologies has shown that the conversion to decentralised hot water generation with natural gas low-temperature boilers was more economical than refurbishment or replacement investment in the waste wood heating plant. In addition, a natural gas CHP plant was installed to cover the company’s own electricity requirements.read more
The investigation of the internal energy flows has shown that due to the insufficient hydraulics of the existing heating network, the already existing waste heat recovery from the cooling water circuit of the oil refinery cannot be fully utilized. The greatest cost savings were achieved by the recommended conversion to natural gas instead of heating oil.read more
Various measures for optimising insulation in the steam and condensate network (e.g. insulation for steam and thermal oil fittings) were developed and economically evaluated. A catalogue of measures with investments, savings and amortisation periods was drawn up.read more
