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 discloses a pellet roasting device, which comprises an upper combustion chamber, a lower combustion chamber and a roasting beaker, wherein the upper combustion chamber, the lower combustion chamber and the roasting cup are connected sequentially from top to bottom and are in a cylindrical shape integrally. According to the provided pellet roasting device, a structure is improved, so that the combustion sufficiency of gas is improved, the radiating and edge effects of the roasting beaker are reduced, energy is saved, the problem of large quality difference of pellets on upper side, lower side, edges and central position of the roasting beaker caused by non-uniform flame and large edge effect during roasting tests of the pellets is solved, and the stable and effective condition is created for the roasting tests and study of the pellets.
