Synergy effects of Novec 1230 and venting on ethanol-gasoline vapor explosion inhibition

This paper studied the characteristics parameters of gasoline vapor explosion through experiments in aφ0.48m * 28.69m long straight pipeline inerted by CO2. By changing the CO2, O2and gasoline vapor concentration, variation laws of gasoline vapor explosion characteristic parameters were explored and analyzed in this paper. Studies have shown that the decrease of oxygen concentration could not only reduce the explosion range, but also change the explosion pressure peak and peak times significantly.

Explosion Process

In this paper, experimental study on gasoline vapor explosion was conducted with data acquisition technology of high-speed camera. In the experiments, the flame behaviors and the flow field movements were shot by the high-speed camera, the space pressure were recorded by high-speed dynamic tester, and the explosion process were analyzed refinedly and intuitively. Studies have shown that according to variations of flame behaviors and pressure characteristics, process of gasoline vapor explosion can be divided into four stages: the ignition stage, the development stage, the intensification stage and the plume stage.

Pressure Characteristics

In this paper, the pressure characteristics of gasoline vapor explosion under weak restrictions was investigated experimentally. The experimental studies have shown that explosion pressure maximized when Rs/R0 was in the range of 1.5~2.0, and when Rs/R0 > 1.5, pressure was proportional to the 2.45 power of the initial radius, and attenuated with the extended distances from the explosion center according to the rule of negative exponent.
