How do you get good carbon monoxide

How do you get good carbon monoxide? A lot of people don't know much about carbon monoxide, and here's the introduction to it:

Carbon monoxide is a colorless, odorless, non-irritating gas. Relative molecular mass is 28.01, the density of 1.25 g/l, freezing temperature is 205.1 ℃, boiling point 191.5 ℃. The solubility in water is very low, very difficult to dissolve in water. The explosive limit of the explosive air was 12.5% ~ 74.2%. Carbon monoxide is easily combined with hemoglobin to form carbon oxygen hemoglobin, make the loss of the ability to carry oxygen and hemoglobin, suffocation of tissues, serious when death. Carbon monoxide has toxic effects on tissue cells throughout the body, especially in the cortex. There are CO in metallurgy, chemistry, graphite electrode manufacturing and domestic gas or coal stove and car exhaust.
