摘要： A steam-generating combustion system includes an oxygen enriched gas provided as at least part of an oxidant stream. A combustion chamber receives and combusts a fuel in the oxidant stream and generate steam. The combustion chamber generates flue gas having a flue gas volume which is smaller than a volume of flue gas generated by the combustion chamber when operated with air as the oxidant stream. A flue gas pollutant control system receives the flue gas from the combustion chamber and reduces at least one of particulate matter, SOx, NOx, and mercury. The reduction in flue gas volume allows the implementation of much smaller pollutant control equipment, since the size of the pollutant control units is mainly based on the volume or mass flow rate of flue gas to be treated. Moreover, the system including oxygen-enriched gas in the oxidant will lead to concentrated levels of the pollutants in the flue gas. The high concentrations of pollutants will enhance their absorption in the different pollutant control systems, improving removal efficiency for all species.

摘要： Steam generation apparatus and methods are presented that are dedicated to oxygen-enriched air combustion of a fuel, wherein the oxygen concentration of the oxygen-enriched air may range from just above 21 percent to 100 percent. One apparatus comprises an oxygen-enriched air preheater through which oxygen-enriched air flows and exchanges heat indirectly with flue gas, creating a preheated oxygen-enriched air stream. The apparatus further comprises a boiler having a radiant section and a convection section, and other heat transfer units adapted to handle reduced flue gas flow rate and higher temperature flue gases than comparable air/fuel combustion boilers, thus allowing a smaller heat transfer surface area, a more compact design and a higher efficiency.

摘要： An improved process for burning solid fuel particles in a combustion chamber and creating a flue gas is disclosed. The method comprises creating a fuel gas stream by mixing the solid fuel particles with a conveying gas, transporting the fuel gas stream through a fuel duct terminating at the combustion chamber at a fuel exit plane and injecting an oxygen stream through an injection device into said fuel gas at an oxygen injection location selected to create a mixing zone to mix the oxygen stream and the fuel gas stream immediately prior to or coincident with combustion of the fuel. Operating parameters of the process can be varied to optimally reduce NOx emissions.

摘要： An air separation unit separates air into an oxygen-rich and oxygen-deficient gas. Fuel gas and the oxygen-rich gas are preheated at heat exchangers through which hot flue gas flows. Combustion of the preheated fuel and oxygen-rich gases result in the hot flue gas. The hot flue gas is cooled at the heat exchangers and flows through a waste heat boiler. Water and/or steam flowing through the waste heat boiler absorbs energy from the cooled flue gas thereby producing heated steam. The heated steam flows through a turbine to produce power. The power is transferred to the air separation unit, thus reducing a power requirement of the air separation unit needed to separate the air.
