The experimental study on the electrical characteristics of flame applied to the measurement of rate of heat release in combustion

摘要

The stability and efficiency of combustion determine utility of fuel and the rate of heat release, which is used to evaluate the performance of combustion organization. However, the walls of low temperature and fire-retardant material are prone to absorb the activated molecules, leading to break of chain reaction and incomplete combustion, which is called flame quenching. This paper mainly investigates the release of CO, the distance of polar plates and value of current during the flame quenching process. In present study, electric field are exerted on the flame, measuring the variation of current and rate of heat release, in order to determine the optimum distance and maximum rate of heat release.
