Abstract: 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.

Abstract: An electric control box (100) for an air conditioner and an air conditioner with the same are provided. The electric control box includes a housing (1); a cooling fin (2) running through the housing (1) and having a part located inside the housing (1) and another part located outside the housing (1); an inner water-guiding part (3) located inside the housing (1) and below the cooling fin (2); an outer water-guiding part (4) located outside the housing (1) and below the inner water-guiding part (3), the inner water-guiding part (3) and the outer water-guiding part (4) defining a water guide passage (a) configured to guide water (b) inside the housing (1) to the outside of the housing (1).

Abstract: An outdoor unit for a central air conditioner and a central air conditioner having the same are provided. The outdoor unit includes a unit body and at least One panel. One side of the unit body is open, and the panel is arranged on the side of the unit body to open and close the unit body. One end of the panel is pivotally and detachably connected to the unit body through a pivot structure. The pivot structure includes a base provided on the unit body and a pivot seat provided on the panel. A top of the base has a pivot shaft spaced apart from the unit body and extending upward, and the pivot seat is provided with a pivot hole having an open bottom and configured to be detachably fitted with the pivot shaft.

Abstract: An outdoor unit for an air conditioner and a housing of the outdoor unit are disclosed. The housing includes a cabinet body, a side-by-side door and a door-latching assembly. The side-by-side door is used to open and close the cabinet body, and includes a first door body and a second door body which are opened side by side. The door-latching assembly includes a cabinet-locking member provided on the cabinet body, a door-locking member provided on the first door body and a latch member provided on the second door body. The latch member is movable with respect to the second door body between a locked position where the latch member cooperates with both the cabinet-locking member and the door-locking member in a locked manner and an unlocked position wherein the latch member is separated from both the cabinet-locking member and the door-locking member.
