Short-flame and large-diameter diesel burner

Abstract

The invention relates to a burner, in particular to a short-flame and large-diameter diesel burner. The short-flame and large-diameter diesel burner comprises a burner shell, an ignition rod and a diesel sprayer, wherein the ignition rod and the diesel sprayer are arranged in the burner shell. The burner shell is a spiral volute, an air inlet is formed in one side of an outer ring of the volute, an air outlet is formed in an inner ring of the volute, the direction of the air inlet is coincident with the tangent direction of the volute, the position of a diesel spraying nozzle of the diesel sprayer corresponds to the position of the air outlet of the volute, and the ignition position of the ignition rod is located above the diesel spraying nozzle and the air outlet. According to the short-flame and large-diameter diesel burner, the burner shell is designed into the volute, air enters the burner in the tangent direction of the volute, the air and diesel are mixed and burnt through centrifugal force, the structure is simple and attractive, the air and the atomized diesel can be more sufficiently mixed, losses of the atomized diesel can be reduced, the diameter of a hearth can be reduced, the size of a boiler can be reduced, and the burning cost can be reduced.

Description

technical field [0001] The invention relates to a burner, in particular to a short-flame large-diameter diesel burner. Background technique [0002] Diesel burners are used for boiler combustion. The mixing degree of air and atomized diesel oil in diesel burners and the shape and diameter of combustion flames of diesel burners can affect the design of the overall structure of the boiler. At present, the air and atomized diesel oil of ordinary diesel burners All have to go through several steps of pre-mixing before igniting and burning. This structure makes the overall structure complex and requires a larger boiler design; moreover, the mixing route is long, which will easily lead to the loss of atomized diesel oil, and the diameter of the combustion flame is small, requiring a larger design. The diameter of the furnace; it is also necessary to configure an independent flame stabilization plate to stabilize the flame, thereby increasing the cost. Contents of the invention ...
