    Abstract: PURPOSE: A method is provided to prevent corrosion of utility boiler side walls and generally to reduce the rate of side wall corrosion of a coal-fired utility boiler. CONSTITUTION: A method of reducing the rate of side wall corrosion in a coal-fired utility boiler while maintaining reduced NOx emission levels, the coal-fired utility boiler comprising a plurality of walls interconnected to form an enclosure, wherein at least one of the walls includes a plurality of burners for introducing a mixture of pulverized coal and primary air into the boiler, the coal-fired utility boiler additionally comprising at least one overfire air port for introducing overfire air into the boiler; the method comprising: providing a plurality of curtain air ports in at least one of the walls; injecting a stream of pulverized coal and a sub-stoichiometric amount of primary air into the boiler through the burners; combusting the stream of pulverized coal and primary air in the boiler; introducing overfire air into the boiler through the at least one overfire air port, wherein the overfire air comprises between about 5% and about 20% of the total air provided to the boiler; introducing curtain air into the boiler through the curtain air ports, wherein the curtain air comprises between about 5% and about 20% of the total air provided to the boiler; and balancing the flow of air through the overfire air port(s) and the curtain air ports such that the ratio of curtain air to overfire air is small enough to maintain combustion staging and assure NOx emission levels of less than about 0.50 lbs. per 10¬6 Btu, yet is large enough to maintain a fuel mixture ratio of less than about 115% of the stoichiometric ratio in the atmosphere adjacent to the walls.

    Abstract translation: 目的：提供一种防止公用锅炉侧壁腐蚀的方法，一般来说降低燃煤电力锅炉侧壁腐蚀的速度。 构成：一种在维持降低的NOx排放水平的同时降低燃煤电力锅炉中的侧壁腐蚀速率的方法，所述燃煤公用锅炉包括互连以形成外壳的多个壁，其中至少一个壁 包括用于将粉煤和一次空气的混合物引入到锅炉中的多个燃烧器，所述燃煤公用锅炉还包括至少一个用于将过热空气引入到锅炉中的过火空气口; 该方法包括：在至少一个壁中提供多个帘式空气端口; 通过燃烧器将粉煤流和次化学计量的一次空气注入锅炉; 在锅炉中燃烧粉煤和一次空气流; 通过所述至少一个过火空气端口将过高的空气引入所述锅炉，其中所述超燃空气包含提供给所述锅炉的总空气的约5％至约20％; 通过帘式空气端口将帘式空气引入到锅炉中，其中帘式空气包括提供给锅炉的总空气的约5％至约20％; 并且平衡通过过火空气端口和帘式空气端口的空气流，使得帘式空气与过热空气的比例足够小以保持燃烧分级并且确保小于约0.5lbs的NOx排放水平。 每10 -6 Btu，但足够大以保持在邻近壁的气氛中的化学计量比小于约115％的燃料混合比。

    Abstract: An arrangement and method in a boiler using fluidized-bed technology. The arrangement comprises a first space (1) of a furnace that comprises means for forming a fluidized bed (21), a second space of the furnace that does not comprise means for forming a fluidized bed, means for feeding fuel into the first space (1) of the furnace, a partition wall (3) that is at least mainly vertical and arranged between said spaces (1, 2) of the furnace to separate them from each other, the arrangement further comprising a roof structure (5) arranged above the first space of the furnace to separate the first space (1) of the furnace from parts of the second space (2) above it, the first space (1) of the furnace being connected to the second space (2) through a flow path (18), which flow path (18) is arranged on the side of the first space (1) of the furnace to lead gases (G) rising from the fluidized bed to the second space (2) of the furnace.

    Abstract: A method of combustion and an apparatus therefor in which separate streams of very lean and very rich fuel/oxidant mixture are combusted separately, the products of combustion therefrom being thoroughly mixed before final combustion takes place. The lean/rich primary combustion minimises combustion temperatures and pollutant formation, whilst the final combustion is substantially stoichiometric.
