Experimental investigation on performance of non-metallic flexible fire-resistance materials in flameproof diesel engine locomotive

Abstract

The investigation was aimed at testing the performances in fire-resistance and transmission efficiency of non-metallic flexible materials in flameproof diesel engine locomotive which may replace traditional metal flame arresters with low gas transmission efficiency. On the basis of the chain reaction mechanism, the mixed gas was burnt in the experiment, and the free radical which can be absorbed by tiny pores of flexible fiber materials and quenched was released. A 9-m-long steel pipeline with an inner diameter of 110 mm was used to simulate the environment of gas transmission. The experimental results showed that flame arresters made of flexible fiber materials can improve the gas transmission efficiency about 3% to 7%, and they also have excellent performances in fire resistance.
