COGENERATION IN ORGANIC RANKINE CYCLE BOILER BASED
Abstract
With the upsurge of the energy efficiency on municipal heating boiler-houses using the organic Rankine cycle computational studies of thermal schemes for low boiling point working medium have been performed. As an object of study the PTVM-100 boiler-house in the city of Kharkov has been chosen. With regard to this boiler-house the possibility of flue gas heat recovery and the partial screening of heat from water network for the use of ORS cycle has been considered. Depending on the applied thermal circuit and the parameters of the used heat the power characteristics of a steam turbine has been obtained. The consumption effect of low boiling point working fluid in the ORC cycle for the occurrence of additional losses in the air condenser has been revealed. It has been also discovered that the use of the closed cycle steam turbines for the low boiling point working bodies allows to implement the principles of cogeneration boiler houses without significant changes in the technological scheme of production of thermal energyKey words: energy conservation, secondary power resources, co-generation, low boiling working fluid, thermal circuit, hot water boiler, water network, flue gases.Downloads
