Premixed pre-evaporation Bunsen burner combustion test device using aviation kerosene as fuel

Abstract

The invention discloses a premixed pre-evaporation Bunsen burner combustion test device using aviation kerosene as fuel, which belongs to the field of energy and environment. Two electric heating devices are added respectively before the fuel inlet and air inlet of a Bunsen burner. Through stored program control of the power of a fuel electric heater, liquid aviation kerosene is fully heated intogaseous fuel, and the gaseous fuel is thoroughly mixed with heated air in the mixing chamber of the Bunsen burner to form flammable mixed gas. Premixed pre-evaporation combustion flame is acquired atthe outlet of the Bunsen burner. The flame temperature or gas composition is measured by a designed thermocouple or sample tube. At the same time, the system uses an air pump and a program-controlledmicro-injection pump to precisely control the air flow and fuel flow. By adjusting the flow ratio of two pumps and by controlling the Reynolds number of the outlet of a lamp tube, two different formsof combustion flames: laminar flame or turbulent flame can be acquired. Diversified flame compensates for the shortcoming of singular flame of the existing Bunsen burner.

Description

technical field [0001] The invention belongs to the field of energy and environment, and relates to a premixed and preevaporated Bunsen burner combustion test device capable of directly burning liquid aviation kerosene. Background technique [0002] In the field of combustion and combustion flame characteristics research, Bunsen burner is often used as a test demonstration device due to its advantages of convenient operation, simple structure, and high flame temperature, and different shapes of flames can be obtained. Bunsen burners that are widely used at present mostly use gaseous fuels such as methane as combustible gas, and the flame shape cannot be controlled. Specifically, it means that laminar and turbulent flames cannot be obtained at the same time, and there is no reference for the actual direct supply of liquid fuel combustion process. in accordance with. In addition, the flame structure of the Bunsen burner using gaseous fuels such as methane as combustible gas i...
