bypassed flue gas stream. Thus, this slipstream reactor can be well insulated so that the temperature drop across the SCR slipstream reactor isbelow 20 ºC. The area of the inside pass is 0.152 by 0.152meter, and the outside pass isa 0.01 meter slot around the inside square. The total height of the reactor is 6.6 meter.

REC Silicon's fluidized bed reactor (FBR) process - REC .

REC Silicon has developed the unique Fluidized Bed Reactor (FBR) silicon refining process, a next-generation method of refining silicon. With the FBR process, we can produce solar-grade silicon at a lower cost, while using 80-90 percent less energy than the traditional Siemens method for converting silane gas to high purity silicon.

5410 Fluidized Bed Reactors - Parr Instrument Company

Fluidized Bed Reactors Parr Fluidized Bed Reactors are used extensively in the chemical process industries. The distinguishing feature of a fluidized bed reactor is that the bed of solid particles or catalyst is supported by an up flow of gas. This reactor provides easy loading and removal of catalyst. This is advantageous when the solids [.]
