Abstract: A method of operation of a thermal power plant having an air separation system with a plurality of air storage unit (ASU) compressors and a liquid oxygen / liquid air (LOX/ LA) storage facility for oxyfuel firing of fossil fuel and a power plant having a control system to perform the same are described. The method is characterized by the step of controlling the net power output of the plant in response to short term variations in grid demanded net plant output by dynamically adjusting the works power of the ASU compressors preferably in conjunction with co-ordinated changes in firing demand. The method is in particular a method to produce an improved primary and secondary response to transient changes in grid demand and to provide accurate response to load dispatch ramps.

Abstract: The present disclosure relates to heat transfer methods and apparatus. The method comprises evaporating a first working fluid in an evaporator in the presence of a second working fluid thereby absorbing heat from circulating water within the process, transporting a mixture of first working fluid and second working fluid to a condenser/absorber where a third working fluid is added and whereby the third working fluid dissolves the second working fluid from the first working fluid causing the first working fluid to condense and transmitting heat to a heat sink, transporting the first working fluid back to the evaporator, transporting the mixture of the second and third working fluids to a separator wherein separation of said second and third working fluids from one another takes place, transporting said second working fluid to the evaporator and transporting said third working fluid to the condenser/absorber. The separation of second and third working fluids may be assisted by injecting of a pressurised gas and use of desiccants. Apparatus to accomplish the method are also disclosed.

Abstract: 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.
