摘要： A high velocity absorber has a lower larger diameter tank section for receiving a slurry at a liquid level in the. tank section, an upper smaller diameter absorber section where liquid scrubbing agent is mingled with flue gas from which impurities are to be absorbed, and a low pressure drop inlet assembly having a transition structure between the tank section and the absorber section for closing a gas flow path and a liquid flow path between the tank section and the absorber section. An inlet housing is connected to and communicates with the transition structure for inlet of flue gas into the transition structure between the tank section and the absorber section.

摘要： A modified air heater gas inlet plenum for a tubular air heater which permits retrofit installation of additional flue gas environmental treatment equipment. A divider plate is located within the inlet plenum to subdivide it into first and second flue gas passages. The first flue gas passage created by the divider plate merely conveys the hot flue gas through the inlet plenum and into flues which convey the flue gas to the new equipment. Return flues convey the flue gas back to the second flue gas passage created in the inlet plenum which, in turn, conveys the flue gas into the tubular air heater heat exchanger tubes. By taking advantage of the large size of a conventional air heater gas inlet plenum, the first and second flue gas passages created by the divider plate still have sufficient cross sectional area so that acceptable flue gas velocities are preserved. One particular application of the modified air heater gas inlet plenum is to permit retrofit application of selective catalytic reduction (SCR) systems for treating flue gas to existing steam generators or boilers.

摘要： A method and apparatus for supporting headers within a tower from adjacent headers thereby reducing the amount of support members needed. In this configuration, the headers, which extend from opposing sides of the tower, are interspaced within the same generally horizontal plane in the tower. Support for the cantilevered end of each header is supplied by the self-supporting capabilities of adjacent headers near their support point with the tower wall. This significantly reduces the loaded span of support members to the distance between such adjacent headers as well as reduces the load upon such support member.

摘要： A spray level arrangement for spraying a liquid absorbent into flue gas flowing through a flue gas desulfurization absorber tower having a shell, includes a pair of elongated headers each having an inlet end for receiving liquid absorbent outside the shell, and an opposite end supported by a shell support at the inner surface of the shell. Each header extends through a penetration port of the shell and into the interior of the shell for supplying the liquid absorbent to the tower. A plurality of elongated branch lines are secured to each header and extend within the tower, each branch line having a supply end connected to the header and an opposite end supported on their own shell supports at the inner surface of the shell. A plurality of nozzles are secured to each branch. The nozzles are configured to spray the liquid absorbent into the flue gas within the tower. A beam in the shell has straps for further supporting the headers in the shell, if required.

摘要翻译： 用于管状空气加热器的改进的空气加热器气体入口增压室，其允许改进安装额外的烟道气环境处理设备。 分隔板位于入口通风室内，以将其分成第一和第二烟道气通道。 由分隔板产生的第一烟道气通道仅将热烟道气输送通过入口集气室，并将烟道气输送到新设备。 回流烟道将烟道气输送回到在入口增压室中产生的第二烟气通道，其又将烟道气输送到管状空气加热器热交换器管中。 通过利用大尺寸的常规空气加热器气体入口增压室，由分隔板产生的第一和第二烟道气通道仍然具有足够的横截面积，从而保持可接受的烟道气体速度。 改进的空气加热器气体入口增压室的一个特殊应用是允许改造选择性催化还原（SCR）系统，用于将烟道气处理到现有的蒸汽发生器或锅炉。

摘要： An anvil arrangement for receiving rapper impacts and transmitting them to a discharge electrode of a precipitator has an electrode tube made of deformable material, having an open end and forming part of the discharge electrode. An anvil having a head and a shank is connected to the head and the shank has a size for insertion into the open end of the tube. The head is larger than the tube for engagement against the open end of the tube. The shank has a recess therein and at least one crimp in the tube near the open end thereof and in the vicinity of the recess of the shank for retaining the anvil to the tube. An alternate embodiment receives the electrode tube therein and engages the tube with an angled groove.

摘要： A forced flow vapor generator wherein at least one of the upright boundary walls of the furnace has upper and lower portions formed of panels of upwardly extending laterally spaced tubes rigidly united throughout most of their length. Some of the panels of the upper and lower wall portions have segments thereof interlaced and coextensive with each other, the interlaced segments being rigidly united to transmit the load of the lower wall portion to the upper wall portion.
