Abstract
An air quality control system (AQCS) 14 useful for treating flue gas FG, such as flue gas FG produced by a fossil fuel fired boiler 12 is described. The AQCS 14 is equipped with a dust separator 37. The dust separator 37 is useful under relatively high dust load conditions downstream from a dry scrubber reactor 36 with limited equipment wear and limited space requirements. As such, the dust separator captures particulate matter with a dust trap that intercepts the flow of particulate matter for collection of the particulate matter in a hopper.
Claims15
An air quality control system for treating flue gas produced in a combustion process to produce cleaned flue gas comprising:
- a dry scrubber reactor with a distribution device therein for dispersal of a moistened reducing agent in a flue gas flowing therethrough;
- a dust separator for capture of particulate matter from the flue gas flowing therethrough;
- and
- a particulate removal device for capture of particulate matter from the flue gas flowing therethrough to produce a treated flue gas for release through a stack.
A dust separator for use in treating flue gas produced in a combustion process to produce cleaned flue gas comprising:
- a dust separator housing fluidly connected to a dry scrubber reactor having a distribution device therein for dispersal of a moistened reducing agent into a flow of flue gas, for capture of particulate matter from the flue gas flowing therethrough from the dry scrubber reactor.
A method of using an air quality control system for treating flue gas produced in a combustion process to produce cleaned flue gas comprising:
- dispersing a moistened reducing agent into a flue gas flowing through a dry scrubber reactor using a distribution device;
- capturing particulate matter from the flue gas using a dust separator;
- and
- producing treated flue gas for release through a stack by capturing particulate matter from the flue gas using a particulate removal device.
