Liquid fuel combustion device used for combustion experiment

Abstract

The invention relates to a liquid fuel combustion device used for a combustion experiment. The combustion device comprises a combustor shell and a floater chamber which are vertically arranged in parallel; the combustor shell is internally provided with an upper layer disc and a lower layer disc from top to bottom sequentially, wherein the upper layer disc and the lower layer disc are both made of porous media; the combustor shell is internally provided with a lamp tube vertically; the upper end of the lamp tube sequentially penetrates through the upper layer disc and the lower layer disc to extend out of the combustor shell; the lower end of the lamp tube penetrates through the bottom of the combustor shell an is communicated with the floater chamber; the lamp tube is internally providedwith a lampwick capable of floating up and down inside the lamp tube; an oil tank is arrange above the floater chamber and communicated with the floater chamber; the floater chamber is internally provided with a floater; and the bottom of the combustor shell is provided with a shielding gas inlet. The invention can generate stable adjustable laminar diffusion flame with better axial symmetry, prevent interferences of surrounding airflow, and maintain flame stability; and meanwhile, the invention can also control fuel oil consumption accurately and be used for mechanism researches of combustion process and development of source codes.

Description

technical field [0001] The invention belongs to the technical field of laboratory equipment, and relates to a combustion device used in a laboratory, in particular to a liquid fuel combustion device used for combustion tests. Background technique [0002] The understanding and understanding of the combustion process is inseparable from the real-time observation and diagnosis of the combustion process. Optical visualization technology has the characteristics of not disturbing the measured object, high test accuracy and fast time response, especially in recent years with the development of laser and CCD technology, visualization technology has become an important means in combustion research. The optical visualization test itself is a very precise and meticulous process, which requires a lot of preliminary work to debug the system and verify its effectiveness. Therefore, before the formal test, a preliminary test is carried out on the burner. The burner can produce a stable l...

AI Technical Summary

Problems solved by technology

[0003] The current burners mainly use gaseous fuel, and there are few studies on liquid fuel burners. The main problem is that the fuel consumption cannot be controlled, the flame is difficult to stabilize under the same conditions, and the repeatability is poor. Furthermore, the wick of the oil lamp burner uses Fibrous material, the irregular shape makes the axial symmetry of the flame not good, and it is continuously consumed during the combustion process, causing the flame to be unstable, which limits the research on the combustion process of liquid fuel
