In this application, a multi-layer spiral airflow will be formed in the combustion tube, thereby increasing the contact area between fuel and air, reducing the influence of turbulent air flow in the combustion tube on fuel combustion, and finally achieving the effect of increasing fuel combustion sufficiency.

The invention discloses an installation structure facilitating to increase an air increment of an engine. The installation structure comprises an intake manifold arranged on a combustion chamber of the engine for feeding air into the combustion chamber, and an air increaser, wherein one end of the air increaser is communicated with the intake manifold, and the other end is connected with one end of an air inlet pipe; the other end of the air inlet pipe is connected with an air outlet of an air filter; a fan is arranged in the air increaser; and when the engine works, the fan works to suck filtered air in the air inlet pipe into the intake manifold so as to enter the combustion chamber. The installation structure facilitates to largely increase the intake increment of the combustion chamber, improves the combustion sufficiency of the combustion chamber, and facilitates to fully exert the engine power.

The invention discloses a petroleum heat extraction multiple thermal fluid generation system adopting petroleum coke as fuel, and belongs to the technical field of petroleum heat extraction. The petroleum heat extraction multiple thermal fluid generation system comprises a slurrying device, a stirring tank, a high-pressure pump, a combustor, a high-temperature separator and a slag storage tank, and the combustor is overall vertically arranged, comprises a combusting chamber and a vaporizing chamber formed in the lower part of the combusting chamber, and further comprises an atomization spray gun, a cyclone and an auxiliary ignition device which are arranged at the top of the combusting chamber. The top swirling combustor cooperates with the auxiliary ignition device, thus water-coke slurryand a combustion improver are mixed and then subjected to high-pressure swirling spray combustion, it is ensured that the water-coke slurry and the combustion improver are sufficiently mixed and atomized, swirl combustion is formed by the cyclone to enhance homogeneous charge compression ignition of the water-coke slurry, the homogeneous charge compression ignition time is prolonged, sufficient combustion of the water-coke slurry is ensured, coke embers and the carbon content of fly ash are reduced, thus the petroleum coke becomes possible for serving as the fuel of a multiple thermal fluid generator, and the cost of multiple thermal fluid thickened oil miming is lowered.

The invention relates to a combustor used for a gas stove. The combustor comprises a big fire cover, a small fire cover and a base, and is characterized in that fire outlet holes, air supply passageways and gas mixing cavities are formed in the big fire cover, fire outlet holes are formed in the small fire cover, a base inner ring and a base outer ring are arranged on the base, and gas mixing cavities and air supply passageways are formed in the base outer ring. The air supply passageways of the big fire cover are matched with the air supply passageways in the base outer ring to form integral air supply passageways. The gas mixing cavities in the big fire cover are matched with the gas mixing cavities of the base to form integral gas mixing cavities. According to the combustor, mixed gas is mixed in the mixing cavities and combusted in the fire outlet holes of the fire covers, sufficient air supply is conducted through the air supply passageways, and therefore the mixed gas can be sufficiently combusted, and the technical effects of improving the heat flux and the heat efficiency of the combustor are achieved.

The invention discloses water gap baking equipment. The water gap baking equipment comprises a furnace body, and the furnace body is provided with a baking chamber for baking a water gap. A combustorfor providing fuel gas through a fuel gas supply pipeline assembly is arranged on the baking chamber, and a smoke exhaust pipe is arranged at the top of the baking chamber. The furnace body further comprises a combustion aiding air preheating chamber which is located at the top of the baking chamber and wrap the circumferential direction of the smoke exhaust pipe, and an air inlet and an air outlet are formed in the combustion aiding air preheating chamber. The air outlet communicates with the combustor, and the fuel gas supply pipeline assembly is connected with a gas pressurizing assembly for increasing the flowing speed of the fuel gas. According to the water gap baking equipment, combustion aiding air is preheated through smoke generated by fuel gas combustion, and meanwhile the flowing speed of the fuel gas is increased through the gas pressurizing assembly. More combustion aiding air can be driven to get into combustion, the combustion sufficiency is improved effectively, and thebaking temperature is improved; and the energy utilization rate is increased, it is ensured that the baking temperature of the water gap meets the needs, and the continuous casting quality is guaranteed.
