Liquid fuel combustion flame-adjusting burner device

Abstract

The invention discloses a liquid fuel combustion flame-adjusting burner device which is characterized in that liquid fuel enters an evaporator premixing evaporation tank body through a liquid conveying pipe by a fuel supply device, and the fuel supply amount is controlled; the premixed gas flow of a gas cylinder group entering the evaporator premixing evaporation tank body is controlled by a premixed gas flow valve; all components in the fuel are vaporized by adjusting the heating temperature, and the fuel in the premixed gas is not condensed before combustion; a co-flow device and a co-flow gas flow valve are used for controlling co-flow gas so as to eliminate the influence of ambient air on combustion flames; and laminar flow and turbulent flow premixed gas combustion flames with different equivalence ratios are realized by adopting a burner outlet structure and fuel flow as well as selective matching of premixed gas types and flow. According to the liquid fuel combustion flame-adjusting burner device provided by the invention, evaporation mixing of multi-component fuel and accurate control of the premixed equivalence ratio are realized, so that the cost of the liquid burner and the difficulty of liquid fuel evaporation mixing control are greatly reduced.

Description

technical field [0001] The invention belongs to a liquid fuel combustion device, in particular to a liquid fuel combustion flame regulating burner device. Background technique [0002] Fuel modification is one of the important technical approaches to improve fuel combustion performance and reduce harmful emissions. On the one hand, fuel modification can optimize combustion, thereby reducing fuel consumption; on the other hand, fuel modification changes the physical and chemical properties of fuel. In addition, a large number of studies have shown that this is conducive to reducing harmful emissions, especially soot emissions. Therefore, fuel upgrading has been highly valued at home and abroad in recent years, and the research on its combustion and harmful emission generation mechanism has important theoretical significance and engineering application guiding value. In order to conduct an in-depth study on the influence mechanism of liquid fuel modification on the combustion...

Simultaneous realization of fuel atomization, gas-liquid mixing and stable supply in this process brings great difficulties to the design of the burner

In order to produce a stable flame and avoid the influence of ambient air and carrier airflow on flame stability, it is necessary to design the most reasonable fuel outlet and carrier gas outlet, and strictly control the flow of carrier gas and fuel supply, which greatly increases the design of the device Difficulty and cost: Due to the different gasification temperatures of the fuel components in the current burner structure, the application difficulty of multi-component liquid fuels is limited, and the liquid fuel combustion experiment cannot be effectively realized
