Is there any evidence of the carbon monoxide then, coal burning without excess oxygen can result in 50% CO, and lots of black smoke.
In the 1930s, I lived next to a coal mine and about an acre of coal piled on the ground about 8 feet high. Areas of that were smoldering with smoke visible but no flames. The wispy smoke had to be mostly CO, there is no way to get enough excess oxygen into the pile to burn to CO2, the part burning is at the bottom where the pressure is and the coal is not cooled by air.
