The invention discloses a heat accumulative
gas burner which comprises an air distribution device, a
nozzle, a gas controlling
assembly, a blocking
brick, a heat accumulator, an ignition device and a
tinder placing device, wherein the main tube of the air ignition device is connected to the right end surface of the
nozzle in a sealing manner, and two breeches tubes at the other end are respectively an air inlet tube and a
flue gas outlet tube. A
cyclone body is arranged inside the hole at the other end which is axial with the opening of the
nozzle, the residual holes are sealed by plugs, and the blocking
brick and the heat accumulator are arranged in the hole which is perpendicular to the opening of the nozzle. A ring channel is arranged inside the tube wall at one end of the ring opening of the nozzle, air hole groove openings are formed uniformly in the ring channel, and the gas controlling
assembly mounted at one end of the openings penetrate the built-in ring channel, so as to introduce gas in the ring cannel. According to the heat accumulative
gas burner provided by the invention, spiral ribs are arranged on the inner wall of the openings and the
cyclone body, so as to enable the
combustion air and the gas to generate rotational air swirl flow, and be beneficial to mixing and blending. According to the device provided by the invention, the ignition device is used to ignite at the first time, and the
tinder placing device ignites later on, the ignition is reliable, and the safety is good.
