Difference between natural gas in gas stove pipeline and canned liquefied gas

Gas stove pipeline natural gas: the main component is methane, which will not be poisoned.

Canned liquefied gas: the main component is carbon monoxide, which can cause gas poisoning. The heat provided by one liter of combustion is about half that of the same volume of natural gas (calculated according to the general civil purity).

The reason is that carbon monoxide will firmly combine with hemoglobin of human red blood cells, making it impossible to exchange oxygen molecules.
