    Abstract: A combustion process for reducing nitrogen oxides in combustors is proposed wherein combustion takes place successively forming an incomplete combustion zone, a reducing combustion zone, and a complete combustion zone, respectively corresponding to primary burners, secondary burners and air ports or after-burners, successively arranged in the direction of gas stream in a furnace. According to the present invention, it is possible to reduce nitrogen oxides by improving a manner of combustion without providing any denitrating apparatuses for exhaust gas.

    Abstract: Reasons of ecology, health and prevention of corrosion require firing methods and furnaces with which the contents of soot and uncombustible gases such as carbon monoxide, hydrogen, hydrocarbons as well as nitrogen oxides and sulfur trioxides do not excess certain levels. This is obtained by a firing method in which a fuel is decomposed with deficient amounts of primary combustion air to combustible gases. Such gases are combusted by the admixture of secondary and tertiary combustion air amounts whereby a flame is obtained which is extended in space and time and, thus, the temperature of which does not rise above moderate values such as 1400.degree. centigrade. Prior to being exhausted, the combustion gases are thoroughly mixed so as to obtain perfect combustion of possibly subsisting combustible substances. Exhausting takes place with heat withdrawal so that cool and pure combustion gases enter the ambiency. The furnace suitable to carry out such method is distinguished by ceramic walls as well as a combustor at the inlet extremity of the furnace. At least one heat withdrawal means is provided downstream the combustor.

    Abstract translation: 生态，健康和防止腐蚀的原因需要燃烧方法和炉子，其中烟灰和不可燃气体如一氧化碳，氢气，碳氢化合物以及氮氧化物和三氧化硫的含量不超过某些水平。 这是通过燃烧方法获得的，其中燃料以不足量的初级燃烧空气分解成可燃气体。 这样的气体通过二次和三次燃烧空气量的混合燃烧，由此获得在空间和时间上延伸的火焰，因此其温度不会升高到中等值如1400℃以上。 在排气之前，将燃烧气体充分混合，以获得可能存在的可燃物质的完全燃烧。 通过放热进行排气，以使冷却和纯净的燃烧气体进入氛围。 适用于实施这种方法的炉子由陶瓷壁以及在炉的入口端处的燃烧器来区分。 在燃烧器下游设有至少一个取热装置。

    Abstract: Carbonaceous fuel is thermally combusted with an amount of air substantially less than that needed for complete combustion to carbon dioxide and water of all the combustible components in the fuel to produce a gaseous effluent containing a substantial proportion of carbon monoxide but little or no nitrogen oxides. Additional carbonaceous fuel is mixed with air, and at least a portion of this mixture is passed into the presence of a solid oxidation catalyst for adiabatic combustion at a temperature above the instantaneous auto-ignition temperature of the mixture but below nitrogen-oxide-forming temperatures. The first gaseous effluent and the gases exiting from the catalyst are mixed and thermal combustion takes place in this mixture to produce a completely combusted final combustion effluent which is low in atmospheric pollutants, particularly nitrogen oxides.

    Abstract: A method of controlling the operation of an oxy-fired boiler includes combusting a fuel that comprises oil heavy residues in a boiler, the oil heavy residues including hydrocarbon molecules having a number average molecular weight from approximately 200 to approximately 3000 grams per mole, discharging flue gas from the boiler, recycling a portion of the flue gas to the boiler, combining a first oxidant stream with the recycled flue gas to form a combined stream, splitting the combined stream into a plurality of independent split streams, introducing each independent split stream at a different elevation of the boiler, and controlling independently a parameter of each of the independent split streams to adjust the heat release at each respective elevation of the boiler to vary the heat release profile of the boiler by adding a second oxidant stream to each respective independent split stream to form respective independent oxygen enriched split streams.
