Title:
RANKINE CYCLE (RC) OR ORGANIC RANKINE CYCLE (ORC) FOR UTILIZING WASTE HEAT FROM BIOMASS COMBUSTION FOR GENERATING ELECTRICITY AND CORRESPONDING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2011/045047
Kind Code:
A3
Abstract:
The invention relates to a Rankine cycle (RC) or an organic Rankine cycle (ORC) for utilising the waste heat from biomass combustion for generating electricity as well as to a corresponding system. In order to achieve an improvement of the overall energy efficiency such that the overall efficiency of the biomass utilisation is enhanced, it is proposed, according to the invention, to design the evaporator so as to correspond exactly to the targeted difference in enthalpy on the boiling curve pre and post evaporation, by means of connecting to this end a controllable heat exchanger upstream of the evaporator, which heat exchanger is regulated to the difference in enthalpy between the pump and the entrance into the boiling curve of the evaporator.
