摘要： A pressurized internal circulating fluidized-bed boiler is incorporated in a combined-cycle electric generating system in which a fuel such as coal, petro coke or the like is combusted in a pressurized fluidized bed and an exhaust gas produced by the combusted fuel is introduced into a gas turbine. The pressurized internal circulating fluidized-bed boiler includes a pressure vessel, a combustor disposed in the pressure vessel and a main fluidized bed combustion chamber provided with an air diffusion device. A thermal energy recovery chamber is partitioned from the main combustion chamber by an inclined partition wall. A fluidized medium flows into and out of the main combustion chamber and the thermal energy recovery chamber. A free board is provided integrally above the main combustion chamber and the thermal energy recovery chamber so that combustion gas from the main combustion chamber and the thermal energy recovery chamber is mixed in the free board.

摘要： A method of combustion of pulverized coal in two stages of combustion to reduce the amount of NOx produced by combustion. In a first stage, exhaust gas is added to air for combustion in a proportion of 35-60% of the air necessary for carrying out combustion. In a second stage, air for combustion is supplied in a proportion of 25-35% of the air necessary for carrying out combustion. In this method of combustion, the pulverized coal is combusted slowly at low temperature with the formation of a flame of low brightness to produce in large amounts activated intermediate components responsible for denitration reaction to promote reduction of produced NOx, and the concentration of CO produced can be reduced by abstaining from using the minimum air necessary for combustion.
摘要翻译：一种在两个阶段的燃烧中的粉煤的燃烧方法，以减少由燃烧产生的NOx的量。在第一阶段，将排气添加到用于燃烧的空气中，以进行燃烧所需的空气的35-60％的比例。在第二阶段，用于燃烧的空气以进行燃烧所需的空气的25-35％的比例供应。在这种燃烧方法中，粉煤在低温下缓慢燃烧，形成低亮度火焰，大量生成负责脱硝反应的活化中间成分，促进生成的NOx的还原，生成的CO浓度减少使用燃烧所需的最低空气。

摘要： A pulverized coal burner including a primary throat having at its forward end a swirler for feeding pulverized coal and primary air in vortical flow, a secondary throat located outside the primary throat for supplying secondary air and a burner throat located outside the secondary throat for supplying tertiary air, the secondary and burner throats being located concentrically with the primary throat having at its forward end a flame sustaining plate diverging outwardly to cause the secondary and tertiary air to flow away from the primary throat along the inner surface of the outwardly diverging forward end portion of the burner throat, to thereby avoid mixing of the secondary and tertiary air with the pulverized coal air in a primary flame region in which the pulverized coal burns slowly and produces NOx in reduced amount. The secondary throat can be moved to adjust the spacing between its forward end and the flame sustaining plate, to adjust the amount of the secondary air and the flow of the secondary and tertiary air. Unburned components of pulverized coal from the primary flame region can be mixed with the secondary and tertiary air in a secondary flame region downstream of the primary flame region and burned at a slow speed at low temperature to reduce the amounts of NOx produced.
摘要翻译：一种粉煤燃烧器，其包括主喉道，其前端具有用于将粉煤和一次空气用于涡旋流的旋流器，位于初级喉部外部用于供应二次空气的次级喉部和位于次级喉部外部的燃烧器喉部，用于提供第三级空气中，次级和燃烧器喉部同心地位于主喉部的前端，火焰维持板向外发散，使得第二和第三空气沿着向外发散的前端部分的内表面从主喉管流出从而避免二次和三次空气与煤粉空气在粉煤燃烧缓慢的一次火焰区域中混合并产生减少量的NOx。次级喉道可以移动以调节其前端和火焰维持板之间的间距，以调节二次空气的量和二次和三次空气的流量。来自主火焰区域的粉煤的未燃烧组分可以与主火焰区域下游的二次火焰区域中的二次和三次空气混合，并在低温下以低速燃烧，以减少产生的NOx的量。
