ENERGY STORAGE TECHNOLOGY FOR DEMANDED SUPPLY OPTIMISATION

摘要

A comburant gas supply system for a combustion boiler/turbine of a thermal power plant, a combustion boiler/ turbine system and a thermal power plant including the same are described. The gas supply system has an air separation module to separate and output an oxygen rich gas from an input air supply; a comburant gas storage module fluidly connected to the output of the air separation module for storage in liquid state of separated oxygen rich gas; a comburant gas supply module to supply the oxygen rich gas to the combustion boiler selectively from the air separation system and/ or the comburant gas storage system. It is characterized in that the air separation module has an oxygen rich gas output capacity that is determined from a demand rating for the combustion boiler/ turbine adjusted with reference to a load factor across a predetermined operating period and/ or the ASU size is increased to provide longer term energy storage capacity than previous sizing based on load factor.
