摘要：
A small-size experimental platform was developed to study the effect of ignition position on horizontal flame spread of 2 cm thickness latex foam. The ignition position was 0 (x1), 3.54 cm (x2), 7.08 cm (x3), 10.62 cm (x4), 14.16 cm (x5) and 17.70 cm (x6) from the center point of the material surface. The characteristic parameters, such as surface temperature, mass loss, flame height and flame spread speed were measured during the tests. The results showed that the average flame spread rate is 0.24, 0.23, 0.19, 0.31, 0.42 and 0.51 cm•s-1 for the tests that the ignition position is far from the center point of the material. At the x3 ignition position condition, the average flame height and mass loss rate was lower and the combustion time was longer than the other tests due to the difference of the heat transfer mode. Then the heat transfer mechanism of the combustion process with different ignition position was analyzed. © All Right Reserved.
