carbon monoxide explosion in coal mill

· monitoring of carbon monoxide (CO) in coal bunkers and coal mills is extremely important. CO is an odorless and very toxic gas and imposes a serious explosion threat at levels

CO Measurement in Coal Fired Plants

Measuring carbon monoxide (CO) can help to determine the excess oxygen setpoint. CO is the most sensitive indicator of incomplete combustion. As the amount of excess O 2 is reduced, the emergence of CO will occur before

Experimental and simulation studies on the influence of

In underground coal mines, methane is the primary explosive gas. Other gases, such as carbon monoxide (CO), ethane, or hydrogen, produced from the spontaneous combustion of coal, can also affect the explosion characteristics of methane (Li and Si, 2010, Peng et al., 2011, Wang et al., 2011, Huang et al., 2012). Previous studies

At which temperature does carbon monoxide explode?

At a wide range of temperatures. If mixed with air in a proportion between 12 and 75% it is explosive (assuming a there is an ignition source) I think this is at standard temperature and pressure 273K, 0.1 MPa. Note that 1% of CO in air will cause death within 3 minutes due to its toxic effects. Share. Improve this answer.

Generation rate of carbon monoxide from burning charcoal

For each sample, four independent variables the mass of the sample, the flow rate of the exhaust gas, CO concentration in the exhaust gas and the combustion time of the sample were measured, and the CO generation rate was calculated. The generation rate of CO from the charcoal was shown to be 137185 ml/min/kW.
