Ammonia torch burner

Abstract

The invention relates to an ammonia torch burner which comprises a gas inlet barrel, a pilot burner ignition assembly, a fuel gas conveying part, a premixer and a combustion chamber. The premixer comprises a mixing cavity and an expanded cavity which is formed at the upper end of the mixing cavity and is communicated with the mixing cavity; the mixing cavity is formed at the upper end of the gas inlet barrel and is communicated with the gas inlet barrel; the upper end face of the gas inlet barrel extends into the mixing cavity; the combustion chamber is formed at the upper end of the expanded cavity and is communicated with the expanded cavity; the fuel gas conveying part comprises a fuel gas conveying main pipe, a fuel gas ring-shaped pipe communicated with the fuel gas conveying main pipe, and a plurality of fuel gas output tubes which are peripherally distributed on the fuel gas ring-shaped pipe and are communicated with the fuel gas ring-shaped pipe; the fuel gas ring-shaped pipe sleeves the periphery of the gas inlet barrel; spray nozzles of the fuel gas output tubes are radially inclined towards the axis of the gas inlet barrel and axially extend upwards into the mixing cavity; the spray nozzles adopt a necking-down form. The ammonia torch burner can realize complete combustion of ammonia and avoid the environment problem caused by residual ammonia.

Description

technical field [0001] The invention relates to a combustion device, in particular to an ammonia torch burner. Background technique [0002] The existing ammonia torch burner adopts a straight-through structure, the flame spreads and burns on the burner, the degree of mixing with air is poor, and the combustion is insufficient, resulting in environmental pollution problems; the head has poor corrosion resistance and high temperature resistance, resulting in maintenance high cost. Contents of the invention [0003] In view of the above-mentioned technical problems, the object of the present invention is to provide an ammonia torch burner with stable combustion, which can completely mix ammonia and air to achieve full combustion. [0004] The technical solution adopted by the present invention to solve the technical problems is: an ammonia gas torch burner, including an air intake cylinder, an ignition lamp assembly, a fuel gas delivery part, a premixing chamber and a combu...
