Abstract

The invention provides a design method of a secondary air inlet barrel and a combustor system thereof. Two ends of a secondary air inlet cylinder are opened, one end of the secondary air inlet cylinder is connected to the large diameter end of a transitional barrel to form a diffused combustion space and the other end of the secondary air inlet cylinder is connected to the large diameter end of a third-time air inlet transitional ring to serve as a diffused combustion exhaust channel. The secondary air inlet barrel is characterized in that multiple rows of air inlet holes are formed in the secondary air inlet cylinder, and the inner diameters of the air inlet holes are increased and decreased successively in a direction from the transitional barrel to the third-time air inlet transitional ring. By means of change of the inner diameters of the air inlet holes, the flow of combustion air changes axially regularly according to the fuel combustion condition in the secondary air inlet cylinder, so that the combustor achieves the optimum combustion efficiency.

Description

technical field [0001] The invention belongs to the technical field of combustion, and in particular relates to a burner for an auxiliary start-up warmer of a power transmission device. Background technique [0002] my country has a vast territory, complex climate and topographical environment, and the power transmission system of special vehicles faces unfavorable factors such as friction pair lockup in extremely cold environments, poor lubrication, reduced battery power supply capacity, and engine ignition difficulties in low-pressure environments, which greatly reduces the reliability of vehicles. sex. As a combustion heat exchange device, the heater transfers heat through the coolant, and can heat the cooling system, lubrication system, transmission system, power system, etc. of the vehicle in extreme environments, so that each system can reach the best working condition. Eliminate the unfavorable factors faced by the vehicle starting. At the same time, the light weight...
