The small household garbage incinerator comprises an incinerator body and a feeding device, an incineration hearth and a reburning hearth are arranged in the incinerator body, and the tops of the incineration hearth and the reburning hearth communicate with each other; a first air distribution system is arranged on the lower portion of the incineration hearth and used for feeding hot air to serve as primary air so as to blow household garbage to be in a rotating state and provide oxygen. A second air distribution system is arranged in the middle of the incineration hearth and used for feeding hot air to serve as secondary air so as to push combustible materials to continue to rotate and supplement oxygen. The upper part of the incineration hearth is connected with a tertiary air pipe which is used for feeding gasified garbage water as tertiary air so as to burn out combustible components in the garbage water; a spiral protruding edge is arranged on the inner side wall of the reburning hearth from top to bottom and used for guiding smoke to spirally descend. Conditions can be provided for garbage burnout in a small space, combustible materials enter the reburning hearth in the tangential direction to be continuously burnt after being heated and burnt in the burning hearth for a period of time, auxiliary fuel is saved, and the burning cost is reduced.

The invention discloses a hearth structure of a circulating fluidized bed boiler for purely burning furfural residues, and solves the problems of how to ensure sufficient burning of burning materials and how to avoid smoke return and fire channeling phenomena when the furfural residues enter the hearth, and how to ensure that slag is easy to form on a heating surface in the hearth and how to avoid the occurrence of the phenomena of smoke return and fire channeling when the furfural residues enter the hearth. A secondary air lower annular air bellow (13) and a secondary air upper annular air bellow (14) are respectively arranged on the outer side wall of the hearth (2) at the dense-phase area (11); the air distribution quantity of a secondary air lower branch air pipe (15) is equal to that of the secondary air upper annular air bellow (14); the ratio of the secondary air distribution quantity to the primary air distribution quantity in the hearth is 55: 45; a furfural residue feeding port (17) is arranged on the outer side wall of the hearth (2) between the secondary air lower annular air bellow and the secondary air upper annular air bellow, the shrinkage ratio of the hearth on the dense-phase area (11) is 40%, and the pressure intensity at the furfural residue feeding port in the dense-phase area of the hearth is zero by setting the air inducing capacity of an induced draft fan (19).

The present invention discloses a burner, comprising: a shell, the interior of which has an annular outer fire cavity; an ejection pipe, comprising an ejection section and a redirection section arranged along the gas path, the ejection section is used to eject air from an air inlet and mix it with the gas; the redirection section is used to change the gas path direction and make the ejection direction of the gas outlet tangent to the outer fire cavity. The present invention also discloses a gas stove having the burner. The present invention has the beneficial effect of extending the flow path length of the mixed gas, thereby improving the distribution uniformity, thereby improving the combustion uniformity of the outer fire ring.

The utility model provides an environment-friendly flare iron tower, which belongs to the technical field of flare iron towers and comprises a bottom plate, a flare tower body, a protective iron tower, a combustion furnace, a wind shield, a support rod and a rainproof and dustproof component. A flare tower body is fixedly installed in the center of the upper surface of the bottom plate, a protection iron tower is fixedly arranged on the outer side of the flare tower body, a combustion furnace is fixedly arranged in the center of the top of the flare tower body, a wind shield is fixedly arranged at the top of the flare tower body, and a plurality of air inlet holes are formed in the upper surface of the wind shield in a penetrating mode. The air inlet hole penetrates through the lower part of the inner side surface of the wind shield; by arranging the wind shield and the rainproof and dustproof assembly, the wind shield shields the combustion furnace, prevents the combustion furnace from being extinguished due to wind blowing and ensures combustion of flammable waste gas, and the n-shaped pipe on the rainproof and dustproof assembly can shield the upper part of the combustion furnace, so that the situation that the combustion furnace is extinguished due to the fact that the combustion furnace is wetted by rainwater is prevented; and normal combustion of waste gas is ensured.

The utility model discloses a welding torch head structure, including the gun body, telescopic gas nozzle and oxygen nozzle, the gas nozzle is connected with the gun body end hinged seat through the damping hinged connection, and is provided with the adjusting handle of drive gas nozzle swing up and down. The gas nozzle is connected through multistage telescopic sleeve between the hinged seat, and this sleeve contains one -level fixed sleeve, two -level movable sleeve and three -level movable sleeve, realizes the accurate telescopic of gas nozzle and locking, adjusting handle and gas nozzle parallelly arranged, through the linkage adjustment of driving link, the up and down angle of gas nozzle is adjusted, makes welding flame can be fully mixed with oxygen under 30 to 60 angle of inclusion, ensures that combustion is full, reduces carbon deposition. Further, the welding torch of the utility model still includes the control switch of being located on the gun handle and is used for adjusting the swing component of gun handle left and right swing angle, effectively reduces the operator fatigue in the welding operation and improves the working stability.
