摘要： This invention pertains to a discharge restrictor secured to the lower end region of impingement members installed in the flue gas path of a circulating fluidized bed boiler. The discharge restrictor incorporates a pivotable baffle plate that prevents the flue gas from bypassing the impingement members yet allows the particles that are collected to gather in an adjacent storage hopper. The baffle plate is normally biased to block access to the storage hopper until a sufficient mass of particles collect on the baffle plate thereby overcoming this bias. In doing so, the plate temporarily pivots to the open position enabling the particles to advance towards the storage hopper.

摘要： A method and apparatus for controlling the combustion of multiple fuels, especially fuels having diverse combustion air requirements. A heating rate demand signal indicative of the heating rate desired is generated and is compared with a fuel based fuel heating rate signal. The larger of the two signals is selected to be an air demand signal that serves as set point for a combustion air controller. The flow rates of each of the fuels being burned is monitored and the resulting signals are scaled and summed to produce the heating rate signal. The fuel signals are also scaled by factors reflecting the combustion air requirements of the fuels. The signals are summed and combined with the fuel heating rate signal to produce a feedforward signal which in turn is combined with a signal reflecting the measured combustion air flow to produce an equivalent air heating rate signal. This latter signal is communicated to the combustion air controller and if different than the air demand signal causes an adjustment of the combustion air controller. The equivalent air signal is also compared with the heat demand signal and the lower of these two signals is communicated to a fuel heating demand subsystem which controls the metering of the fuels. An 0.sub.2 set point generator modifies the feedforward signal should a deviation occur between the 0.sub.2 set point and the measured 0.sub.2 content of flue gas exhausted by the combustion process.
摘要翻译：用于控制多种燃料的燃烧的方法和装置，特别是具有不同燃烧空气要求的燃料。产生指示所需加热速率的加热速率要求信号，并将其与基于燃料的燃料加热速率信号进行比较。两个信号中的较大的信号被选择为用作燃烧空气控制器的设定点的空气需求信号。监测每个被燃烧的燃料的流量，并将所得到的信号进行缩放和相加以产生加热速率信号。燃料信号还通过反映燃料的燃烧空气需求的因素来缩放。将信号相加并与燃料加热速率信号组合以产生前馈信号，该前馈信号又与反映测量的燃烧空气流的信号组合以产生等效的空气加热速率信号。后一个信号被传送到燃烧空气控制器，并且如果不同于空气需求信号导致燃烧空气控制器的调节。等效空气信号也与热需求信号进行比较，并且这两个信号中的较低的信号被传送到控制燃料计量的燃料加热需求子系统。 02设定点发生器修改前馈信号，如果在02设定点和被燃烧过程排出的烟道气测量的O2含量之间发生偏差。

摘要： Apparatus for separating solids from flue gas in a circulating fluidized bed (CFB) boiler comprises plural vertical, impact type particle separators located within the CFB in a plurality of staggered rows. The impact type particle separators employ hung elements supported from fluid-cooled tubes which form a collecting channel, typically U-shaped, which separates particles from flue gases conveyed across the particle separators. By separating the support function from the collection shape required by functional performance considerations, the strength requirements of the material used to form the collection shape are reduced and the strength of the material from which the fluid-cooled support is made is much higher due to the lower operating temperature of the material comprising the fluid-cooled support, thereby permitting the use of lower cost materials.

摘要： An improved CFB reactor or combustor arrangement has at least a first and a second group of impact type particle separators or U-beams with cooling surfaces located adjacent and immediately upstream of the second group of U-beams which serve to cool flue gas/solids flowing through the CFB before it reaches the second group of U-beams. By reducing the gas temperature in the vicinity of and entering the second group of U-beams, the U-beams can be made of less expensive materials and are thus less expensive to produce and maintain. The heat absorbed by the local cooling surfaces can be applied to heat a working fluid supplied to a turbine or other process.

摘要： A circulating fluidized bed (CFB) boiler has one or more bubbling fluidized bed enclosures containing heating surfaces and located within a lower portion of the CFB boiler to provide a compact, efficient design with a reduced footprint area. The heating surfaces are provided within the bubbling fluidized bed located above a CFB grid and/or in a moving packed bed below the CFB grid inside the lower portion of the CFB boiler. Solids in the bubbling fluidized bed are maintained in a slow bubbling fluidized bed state by separately controlled fluidization gas supplies. Separately controlled fluidization gas is used to control bed level in the bubbling fluidized beds or to control the throughput of solids through the bubbling fluidized beds. Solids ejected from the bubbling fluidized beds can be returned directly into the surrounding CFB environment of the CFB boiler, or purged from the system for disposal or recycle back into the CFB. Solids which are recycled back to the CFB have less heat and can be used to control the temperature of the fast moving bed in the CFB.
摘要翻译：循环流化床（CFB）锅炉具有一个或多个含有加热表面并且位于CFB锅炉的下部内的起泡流化床外壳，以提供紧凑，有效的设计，减少占地面积。加热表面设置在位于CFB格栅上方的起泡流化床内和/或在CFB锅炉下部的CFB格栅下方的移动填充床中。鼓泡流化床中的固体通过单独控制的流化气体供应维持在缓慢的起泡流化床状态。单独控制的流化气体用于控制鼓泡流化床中的床层或控制通过鼓泡流化床的固体的通过量。从起泡流化床喷出的固体可以直接返回到CFB锅炉的周围CFB环境中，或者从系统中清除，以便将其回收回CFB。循环回CFB的固体具有较少的热量，可用于控制CFB中快速移动床的温度。

摘要： A circulating fluidized bed processor has a processor enclosure at least partially defined by a front wall and a rear wall spaced away from the front wall. A bottom wall is connected between the front and rear walls and a mechanism is provided for supplying primary air through the bottom wall for fluidizing a circulating bed in the enclosure. Another mechanism is provided for recirculating the bed from a top of the enclosure back to the enclosure. One or more secondary air plenum(s) are provided in the enclosure between the front and rear walls for supplying secondary air into the fluidized bed, above the bottom wall, so that secondary air reaches deep into the enclosure. The plenum(s) are formed of a waterwall which has a plurality of openings therein to allow communication of gases and solids therethrough from one side of the waterwall to the other.
