SYSTEM DESCRIPTION
**************************************************************************
NOTE: Select the applicable paragraph(s) from the
following:
**************************************************************************
**************************************************************************
NOTE: Use these paragraphs for multitube collectors
150 mm 6 inch diameter collecting tubes may cause a
plugging problem. Designer must investigate flue
gas particulate size, distribution and tendency of
particulates to adhere to each other for the
specific project before selecting diameter of
collector tubes.
**************************************************************************
**************************************************************************
NOTE: The third sentence of this paragraph shall be
used only when dust collector is used with spreader
stoker-fired boiler.
**************************************************************************
[Dust collector(s) shall be multitube, mechanical cyclone type, having
collector tubes in accordance with ICAC M-2, ICAC M-4, ICAC M-5, and ICAC
M-6. Collector(s) shall remove fly-ash from flue gas produced by a
[pulverized coal-fired boiler] [spreader stoker-fired boiler] [underfeed
stoker-fired boiler] [No. 6 fuel oil fired boiler] [refuse fired waste
disposal incinerator of water wall furnace design]. [There shall not be
any reinjection from dust collector hopper(s) into spreader stoker-fired
boiler.] Collector(s) shall be designed for [indoor] [outdoor]
installation and located in the flue-gas system between [_____] outlet and
[_____] inlet [existing] locations. Provide necessary gas distribution
devices in the ductwork ahead of and at the entrance of the dust
collector(s) to ensure even gas flow into the dust collector(s).]
**************************************************************************
NOTE: Use this paragraph for 600 mm 24 inch or
larger diameter cyclone collectors. A choice of
diameter is dependent upon design parameters that
must be analyzed.
**************************************************************************
[Dust collector(s) shall be high-efficiency, mechanical cyclone-type, [600
mm] [24 inch] [_____] diameter centrifugal cyclone body with tangential
entry having arrangements of one, two, four, or more parallel unit
combinations in accordance with ICAC M-2, ICAC M-4, ICAC M-5, and ICAC M-6.
Collector(s) shall remove fly ash from flue gas produced by a refuse fired
waste disposal incinerator of the no-boiler furnace design. Collector(s)
shall be designed for [indoor] [outdoor] installation and located in the
flue gas system between [_____] outlet and [_____] inlet [existing]
locations. Provide necessary gas distribution devices in the ductwork
