Abstract

In the article an analysis on possible ways of low-temperature waste heat utilization is performed. If well designed, this could contribute to increase efficiency of CHP plants without introducing many complex changes to the whole system. The main analyses were focused on the location of the regenerative heat exchanger in the facility. This could differ with varying temperatures of working media in the system. The base for investigations was a 100 MW power unit operating in off-design conditions and supplied with steam from an OP-430 boiler. Modifications to the model were made using commercially available software and by applying the Stodola equation and the SCC method. It allowed determining the most suitable position for installing the low-temperature heat exchanger. According to performed calculations for off-design conditions, after performing some modifications in the system, both heat and electricity generation could be increased due to addition of a low-temperature heat exchanger.
