Why domestic gas burns with a blue flame?
The hotter a hydrocarbon gas burns, the bluer the flame. An orange flame indicates a cool flame with incomplete combustion since soot (unburnt carbon) glows orange. Hydrogen gas burns so completely and so hot that it emits light in the ultraviolet. You cannot see a hydrogen gas flame. Alcohol fires, similarly, tend to burn very efficiently and are nearly invisible--as anybody who watches NASCAR races knows.
