    摘要： An oxygen fired power generation system is disclosed. The power generation system has a high pressure combustor having a water recycle temperature control subassembly, and an intermediate pressure combustor having a CO2 recycle temperature control subassembly. Thus, a first energy cycle utilizes a first energy source operatively associated with a corresponding first heat sink, and a first inert agent to provide energy transfer therebetween and temperature control during operation of the first energy source. In like fashion, a second energy cycle utilizes a second energy source operatively associated with a corresponding second heat sink, and a second inert agent to provide energy transfer therebetween and temperature control during operation of the second energy source. The first and second energy sources are not identical, the first and second heat sinks are not identical and the first and second inert agents are not identical. The first and second energy cycles are configured in combination to provide a power generation unit.

    摘要： A process for burning a sulfur-containing fuel to produce a flue gas. The process includes introducing a sulfur-containing fuel into a combustion chamber, introducing an oxidant stream into the combustion chamber and mixing it with the sulfur-containing fuel to define a combustion zone, and introducing potassium carbonate into the combustion chamber. The sulfur-containing fuel is burned to produce the flue gas and potassium sulfate.

    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 improved process for burning a fuel to produce a flue gas is disclosed. The fuel is burned in a main combustion zone in the presence of a main combustion oxidant to produce combustion products. The combustion products are mixed in a post-combustion zone positioned downstream from the main combustion zone. The post-combustion zone is provided with a recirculation zone positioned proximate to the main combustion zone and an injection zone positioned downstream from the recirculation zone. An post-combustion oxidant is injected into the combustion products in the injection zone. At least one of (a) the residence time of the combustion products in the post-combustion zone, (b) the temperature range of the combustion products contained within the injection zone and (c) the oxygen content of the oxidant is controlled to optimize the level of CO and NOx in the flue gas.

    摘要： Combustion process especially applicable to cement works, in which process it is desired to use fuels which are difficult to ignite. To do so, a flame comprising a primary zone and a secondary zone is created. The hot primary zone is created using an oxy-fuel flame, which makes it possible to preheat the fuel which is difficult to ignite so as to raise it to the suitable temperature in the secondary zone where it burns, with air, in order to create the main flame. Applications: cement, metallurgy, glass, etc.

    摘要： A kiln adapted to recycle kiln dust includes a recycle dust pipe in fluid communication with an oxidant stream to increase the concentration of oxygen in the fluidized recycle dust before the recycle dust stream is directed into the kiln flame. Increasing the oxygen concentration in the recycle dust stream improves the efficiency of the recycling process. A supplemental fuel stream may be introduced into the recycle dust stream to provide an additional flame to preheat the recycle dust stream before the recycle dust stream is directed into the kiln flame.
