Performance Analysis of a Biomass ORC Poly-generation System

This paper shows monitoring results of the operation of a biomass fuelled combined heat and power (CHP) plant using the Organic-Rankine-Cycle (ORC) technology and a district heating network as a heat sink. Furthermore a decentralised thermal cooling system, connected to the district heating is being described. Annual analyses focus on the performance of the facilities and the optimisation potential. Monitoring data from the control system and various sensors in the cycle are assessed over several annual periods. The results give an overview of the economic and ecologic performance of the facility. Auxiliary energies are discussed in detail. Economical and ecological aspects of the system are discussed.
