Burner Tube and Space Heater Employing the Tube

摘要

A pressurized space heater for burning gaseous fuel has as its main component a generally conical burner tube that receives at its narrow end a combustible mixture of fuel and primary air. Complete combustion in the tube is enhanced by two sets of holes disposed along the tube for admitting secondary air. The location, number and sizes of the holes are so chosen as to ensure complete combustion and to avoid the production of noxious substances.
