This invention relates to the field of burner technology, specifically a burner for a gas-fired wall-hung boiler, comprising a rear mounting bracket and a venturi tube mounted on its front side. The front side of the venturi tube is connected to the front mounting bracket, and a temporary storage frame is fixed to the front side of the front mounting bracket. A burner head of the venturi tube is mounted above the venturi tube. In this burner, when the rotating rod drives the convex column to rotate, the convex column intermittently applies a downward thrust to the convex block. This causes the convex block to drive the piston assembly to intermittently reciprocate within the gas storage pipe. Therefore, the piston assembly reciprocates to draw gas and air from the main pipe into the gas storage pipe and then discharges the gas and air from the gas storage pipe. This repeated operation allows for thorough pre-mixing of the pre-mixed gas and air, improving the completeness of subsequent combustion, reducing exhaust emissions, and lowering gas consumption, thus achieving excellent energy-saving and gas-saving effects.
