Solid/liquid combustion reactor for flame disturbance observation

Abstract

The invention discloses a solid / liquid combustion reactor for flame disturbance observation. A sample disc, a left disturbance disc and a right disturbance disc are arranged in the reactor, disc holesare formed in the peripheries of the left disturbance disc and the right disturbance disc, a sample inlet hole is formed in the bottom of the sample disc, a sample inlet hole valve and a temperaturedetector are assembled in the sample inlet hole, and an oil pool is arranged on the sample disc. A side hole is formed in the side wall; an ignition agent spray pipe, an electric spark igniter and twopairs of thermocouples are arranged at the periphery of the oil pool; wherein the side hole is used for controlling the relative height of the disturbance disc and the oil pool and the rotation angleof the disturbance disc. A range finder is arranged on the bottom surface of the top cover and is used for detecting whether the disk hole of the disturbance disk is coaxial with the oil pool and monitoring the thickness of the oil pool. According to the invention, setting, transformation and combination of various disturbance conditions in combustion of the liquid fuel and the solid fuel can berealized, the experimental environment is closed, convection is low, multiple experimental preparatory works of the liquid fuel are realized, the solid / liquid combustion flame is effectively observed,and related data of the solid / liquid fuel combustion flame state and flame propagation in the disturbance state are enriched.

Description

technical field [0001] The invention belongs to the field of burners, and relates to a burner for scientific research with a movable disturbance disc and a fuel support surface for observing combustion flames of solid and liquid fuels. Background technique [0002] Combustion and flame are currently one of the research directions that are focused on in the fields of combustion, chemistry, energy engineering, environmental science and engineering. In most cases, combustion refers to a physical / chemical coupling phenomenon that occurs in a high-temperature plasma state, and flame is a phenomenon in which combustible gases emit intense light, generate heat, and rise with the flow field in the combustion state. Combustion and flame phenomena are relatively complex as a whole, involving variable fluid mechanics and chemical reaction kinetics factors. Using high-speed cameras to directly capture the flame shape and intuitively obtain the combustion state is one of the widely used ...

AI Technical Summary

Problems solved by technology

At present, the research on the disturbance of solid fire / liquid fire flame spread and stable combustion flame is still quite limited. The convection of the open combustion oil pool is seriously affected, and the large-scale combustion equipment and thick oil pool involve the influence of various parameters. Suitable for current targeted research on disturbance

[0005] It can be seen that there is still a lack of effective reaction devices and observation equipment for the research of liquid fuel and solid fuel under disturbance state, and the research of liquid fuel and solid combustion under disturbance state is related to fuel transport research, fire spread research and fire research. It is one of the important directions for future research on liquid fuel and solid fuel combustion.
