A comprehensive utilization system for high-temperature gasification and low-nitrogen combustion of biomass comprises a gasifier, a boiler and a burner installed on the boiler. The outlet of the gasifier is connected to a fuel inlet of the burner. The boiler is provided with flue-gas exhaust ports connected to a chimney. Regenerative heat exchangers are provided between the flue-gas exhaust ports and the chimney, preheating air pipes are connected to the regenerative heat exchangers and then to an auxiliary mixing chamber. The auxiliary mixing chamber is provided with a first outlet connected to the inlet of the mixer, and a second outlet connected to the high-temperature air inlet of the gasifier and the second combustion-air inlet of the burner. An outlet of the mixer is connected with the first combustion-air inlet of the burner. The chimney is connected with the flue gas inlet of the gasifier through pipes and fans.

The invention discloses a vacuum cracking apparatus for a power battery and a cracking method thereof. The cracking device comprises a cylinder and further comprises a rolling device, a first sealing device, a cracking device, a second sealing device, a pyrolysis device and a third sealing device which are arranged from top to bottom. The cracking device for the power battery of the present invention is equipped with the first sealing device, the second sealing device and the third sealing device to isolate the cracking device from the pyrolysis device and be capable of realizing material transmission and gas isolation without interference with each other, so that gas stirring between an anaerobic zone and an aerobic zone is avoided; and by combing battery cracking and battery pyrolysis, with cracked gas discharged after cracking as a fuel for cracking and pyrolysis or preheating a pyrolysis device, resources are fully used.

The invention provides a thermal cracking system which comprises a reactor, and a feed module or a solid product discharge module. The feed module transports a feed material from the outside environment to the reactor. While being transported, the feed material is heated by the feed module to become molten and fills up the interior of the feed module, thereby preventing air from entering the reactor. The solid product discharge module transports a solid product from the reactor to the outside environment. One end of the solid product discharge module is connected with the reactor. The other end of the solid product discharge module comprises a first opening interfacing with the outside environment. When the solid product is transported to the outside environment, the opening size of the first opening is selected such that the speed at which the solid product is entering the solid product discharge module form the reactor is equal to or greater than that at which the solid product is leaving the solid product discharge module, through the first opening, and into the outside environment. Benefit of the invention includes a higher production efficiency and enhanced safety for a thermal cracking system at industrial scale.

A system for inerting a biomass feed assembly the system including a combustion chamber operably connected to the biomass feed assembly to receive a biofuel, the combustion chamber operable to combust the biofuel and generate a flue gas therefrom and a conduit operably coupled to at least one of the combustion chamber and an inert gas source, and the biomass feed assembly, the conduit operable to carry a gas to the biomass feed assembly. The gas sweeps dust generated in at least the gravity chute assembly toward the combustion chamber and the gas maintains an oxygen partial pressure or concentration in the at least a portion of the biomass feed assembly below a selected threshold sufficient to suppress ignition.

Refractory tile for protecting a wall of energy recovery tubes. A hot face of the tile is to be exposed to the interior of the furnace. A cold face, opposite the hot face, defines: a groove extending over the entire length of the tile and to receive one the tubes, and a fastening receptacle configured to receive a retaining member to immobilize the tile with respect to the tube. The tile has, in a transverse section plane, at least at each position between the position of the groove and the position of the fastening receptacle, a non-zero material thickness. The thickness is measured between the transverse profile of the hot face and a straight segment, which is referred to as the base and links the ends of the transverse profile of the hot face. The positions are determined along the base.

A nozzle (1) is configured to deliver gas into an incinerator such as a waste incinerator (3). The nozzle includes a nozzle pipe (20) and a swirl generator (21). The swirl generator includes a plurality of angularly spaced vanes (24) that are attached to an inner surface (19) of the pipe. The vanes terminate radially inwardly at respective vane inner surfaces (36). A continuous central passage (25) extends axially between the vane inner surfaces. Utilization of the swirl nozzles in connection with an incinerator provide improved gas mixing and avoid having regions with insufficient air to achieve complete combustion.
