40 CFR § 76.2 - Definitions. | CFR | US Law | LII / Legal

The principal pollutants from coal-fired boilers, which have been targeted by local and federal regulatory agencies are SO2, NOX and PM 10 particulates. The particular pollution control equipment for a given installation is dependent on the combustion system, the chemistry of the fuel being burned and the applicable regulations.

Pulverized Coal-Firing Boiler Improvement

Tangentially fired boiler means a boiler that has coal and air nozzles mounted in each corner of the furnace where the vertical furnace walls meet. Both pulverized coal and air are directed from the furnace corners along a line tangential to a circle lying in a horizontal plane of the furnace. Turbo-fired boiler means a pulverized coal, wall

Application Note: Flue Gas Analysis as a Boiler Diagnostic

Abstract In this paper, a novel methodology is proposed for the online monitoring of the air-fuel ratio in large pulverised-fuel boilers at the burner level. Using standard measurements, this parameter can only be estimated, as the fuel distribution between burners is generally missing. The detailed air flow distribution to the burners can also be unknown depending on the available measurements.
