Problems solved by technology

The above three conclusions are obtained after studying the effect of ferrocene on the premixed and diffusion flames of gas phase combustion. Whether ferrocene has the same fire extinguishing effect on liquid phase or solid phase combustion flames is not very sure. It is very unfavorable to expand the application range of ferrocene

Embodiment 1

[0022] The ferrocene fire extinguishing experimental system of the present invention comprises a ferrocene evaporation device and a fire extinguishing platform, wherein the ferrocene evaporation device includes a carrier gas source 1, a constant temperature water bath 2, a constant temperature oil bath 3 and a ferrocene evaporation chamber 4, The carrier gas source 1 is connected to the constant temperature water bath 2 to preheat the carrier gas, the constant temperature water bath 2 is connected to the constant temperature oil bath 3, the ferrocene evaporation chamber 4 is placed in the constant temperature oil bath 3, and the constant temperature oil bath 3 heats the carrier gas; The constant temperature water bath 2 and the constant temperature oil bath 3 are respectively connected to the digital display temperature controller 15. A rotameter 16 is installed between the constant temperature water bath 2 and the constant temperature oil bath 3 to control the flow of the carr...

Embodiment 2

[0033] The experimental system is the same as in Example 1.

[0034] Pre-pass the carrier gas before the experiment and use the rotameter to fix the flow rate of the carrier gas at 1.0m 3 / h, heat the water bath to 70°C, since the boiling point of glycerol is 290°C, the temperature of the oil bath can be changed to obtain different concentrations of ferrocene.

[0035] From the experiment, the concentration changes of oxygen, carbon dioxide and carbon monoxide in the flue gas under the action of different concentrations of ferrocene, the mass change and combustion efficiency of the fuel during the combustion process, and the heat release of the fuel can be calculated according to the mass change and combustion efficiency of the fuel rate.

Embodiment 3

[0037] The experimental system is the same as in Example 1.

[0038] Pre-pass the carrier gas before the experiment and use the rotameter to fix the flow of the carrier gas. Since the range of the rotameter is 0-2.5m3 / h, the flow of the carrier gas can be changed to obtain the oxygen and carbon dioxide in the flue gas at different flow rates of the carrier gas. and the concentration change of carbon monoxide, the mass change and combustion efficiency of the fuel during the combustion process, and the heat release rate of the fuel can be calculated according to the mass change and combustion efficiency of the fuel.
