Fully premixed burner and gas water heater

Abstract

The utility model belongs to the technical field of heating, specifically discloses a kind of full premix burner and gas water heater, the full premix burner, including gas supply pipe and porous medium body, the gas supply pipe one end is closed, the other end is equipped with air inlet, the outer periphery of the gas supply pipe has gas outlet area, the gas outlet area is equipped with the gas outlet hole in the communication in the gas supply pipe inside, the open hole rate of the gas outlet area of the closed end of the gas supply pipe is less than the open hole rate of the gas outlet area close to the closed end of the gas supply pipe;Porous medium body, the porous medium body covers the gas outlet area, it can effectively solve the problem that the surface gas temperature of full premix burner is not uniform and is easy to generate nitrogen oxide.
