A low-NOx ammonia-coal stable combustion swirl burner relates to the field of clean combustion of coal with low carbon and low NOx. This invention addresses the problems of ammonia slip and high NOx emissions in existing ammonia-coal co-combustion technologies. In this invention, a primary air / pulverized coal duct is fitted onto a central NH3 duct, forming a primary air channel between them. An outer NH3 duct is fitted onto the primary air / pulverized coal duct, forming an NH3 channel between them. An inner secondary air duct is fitted onto the outer NH3 duct, forming an inner secondary air channel between them. An outer secondary air duct is fitted onto the inner secondary air duct, forming an outer secondary air channel between them. Tangential and axial blades are respectively installed in the inner and outer secondary air channels. This invention is used for pulverized coal swirl combustion.

This utility model discloses a car wash bottle, which includes a bottle body and a threaded cap. The cap integrates an inflation valve, a spray connector, a pressure relief valve, and a pressure gauge. The inner bottom surface of the bottle body has an inverted frustum-shaped liquid collection groove. A filter cartridge is fixed to the bottom end of the suction tube, with its bottom surface contacting the bottom surface of the collection groove. This maximizes the absorption and utilization of the liquid inside the bottle, reducing residue. The filter cartridge effectively filters impurities and eliminates cleaning fluid foam, ensuring stable and smooth spraying. This utility model has the advantages of high liquid utilization and stable operation.

The utility model relates to the technical field of cutting torch equipment, and improves the operation safety of a cutting torch device in the prior art. The cutting torch device comprises a gas inlet pipe assembly which is configured to be connected with an external gas source and convey combustible gas and combustion-supporting gas; the mixed gas chamber is connected with the gas inlet pipe assembly and is used for realizing gas premixing and pressure balance; one end of the jet pipe assembly is connected with the outlet end of the mixed gas chamber, and a nozzle is formed in the other end and used for accelerating flowing of the mixed gas and forming stable jet flow; the one-way valve is arranged on the jet pipe assembly and used for preventing gas from flowing reversely and maintaining the system pressure stable; and the fire arresting piece is arranged on the air inlet pipe assembly and the jet pipe assembly and used for preventing flame burn-back. The device is high in integration level, forms a multiple safety protection mechanism, and remarkably reduces the operation risk.
