Abstract

Many fossil fuel fired municipal heating plants have been upgraded to cogeneration systems through installation of biomass fired cogeneration modules. This paper shows the effects of installation of the Organic Rankine Cycle (ORC) technology based module in the plant with coal fired water boilers. Current problems related to the operation of the integrated system are presented and discussed. Special attention is given to the volatility of main operational parameters that affects economic performance of the project. In search for improvement an installation of new equipment such as heat storage and district heating water cooler are proposed and examined. Mathematical simulation model and optimization algorithm for thermal energy storage capacity sizing was developed using the commercial software EBSILON® Professional. The model was calibrated and validated with real measurement data from the SCADA system of the plant. Results of simulations revealed potential annual financial benefits related to savings of chemical energy of fuels and selling excess electricity on the balancing market. The results of this simulation prove that proposed modifications of the technological system structure can be a good option for increasing investment profitability at the current level of fuel and energy prices.
