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.
