Abstract

The invention provides a diffusion combustion chamber and a combustor system comprising the same. The diffusion combustion chamber comprises a transition cylinder, a secondary air inlet barrel and a tertiary air inlet transition ring, wherein the rear end of the transition cylinder is connected with one end of the secondary air inlet cylinder, and the other end of the secondary air inlet cylinder is connected with the first end of the tertiary air inlet transition ring; and first air inlets are formed in the transition cylinder, second air inlets are formed in the secondary air inlet cylinder, and third air inlets are formed in the tertiary air inlet transition ring. The combustor system comprising the diffusion combustion chamber has the characteristics of being high in combustion efficiency and volumetric power density, reliable in ignition, suitable for various limit environments, and high in heat utilization rate.

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...
