Effect of low-concentration coal dust on gas explosion …

 · As the coal dust concentration increases, the maximum EFPS descends gradually because of two reasons: First, the amounts of coal dust and gas in the system are limited. With part of coal dust and gas already consumed in the previous explosion, the amounts of coal dust and gas are reduced, so are the heat release and the EFPS.
