Fire Detection Methods for Coal Pulverizer Systems

Apr 04, 2017· What is the health and safety problem? Detonating explosives release toxic gases, primarily oxides of nitrogen and carbon monoxide. Nitric oxide (NO) and nitrogen dioxide (NO 2) are produced by large surface blasts in which the explosive does not detonate properly.NO released by the detonation oxidizes to NO 2 as the fumes mix with the atmosphere. . Excessive NO 2 production is …

The measured carbon monoxide signal is transmitted to a derivative action controller 48 which will be sensitive to any variations in the carbon monoxide level and will effectively provide an output signal along line 50 indicative of the slope or rate of change of the carbon monoxide level in the pulverizing mill …

Carbon Monoxide - Safety Training PowerPoint Presentations

(carbon monoxide, soot, smoke, coal). This situation results in a loss of efficiency because not all of the potential energy of the coal is captured in the combustion process resulting in fuel wastes. Combustion processes that run fuel rich are "running dirty" meaning an increase in pollutant emissions.
