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 relates to an apparatus for producing syngas, typically from municipal waste. In particular, a gasifier is used in combination with a plasma furnace. The system is configured so that non-airborne char generated in the gasifier is removed from the system prior to delivery to the plasma furnace. This enhances the energy efficiency of the system whilst still yielding excellent yields of syngas.

Methods and systems are provided for two-stage treatment of contaminated particulate material, such as soil, sediment, and/or sludge. The methods and systems utilize a thermal desorption process combined with a smoldering combustion process. The contaminated particulate material is first exposed to thermal desorption at high temperatures (e.g., greater than 150° C.) to form a heated contaminated particulate material. Next, a smoldering combustion process is initiated by introducing a combustion-supporting gas. The combined process can take place in the same or different treatment units. Treating the particulate material with a thermal desorption process prior to a smoldering combustion process enhances the completeness and throughput compared to operating these processes separately.

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 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.
