摘要:
Heat and electricity for the consumption in industry systems may be purchased at the market or generated internally within the industry. The analyzed industrial energy system consists of a steam boiler, turbine and a heat pump. A linear programming model is presented to determine the optimal strategies for the selection of the optimal energy consumption of heat and electricity that minimize the overall cost of energy. Charts are derived for the selection of the optimal energy supply to the industry system that could be equipped with two types of condensing turbines: with a single steam extraction and without a steam extraction. Results of optimization show that maximally costs saving is up to 88 % for the system with condensing turbine without steam extraction and up to 60 % in the system with turbine with steam extraction.
