助燃气体 combustion-supporting gas
- 此外,必要的助燃气体必须预热,以减少车间必须处理的气体量。
In addition, the required combustion air is preheated to reduce the gas volume that the plant must handle. - 通过预热助燃气体,用于维持燃烧室出口温度的可燃气体逐渐增加。
By preheating the combustion air, the amount of fuel gas required to maintain the combustion chamber outlet temperature decreases. - 但倘若隧道中发生火灾,沥青路面在汽油的助燃下会产生大量的有毒气体和黑烟,因此研究适用于隧道的阻燃抑烟环保沥青混凝路面可明显提高隧道的防火能力。
The asphalt pavement is more suitable in tunnel but the asphalt with burning oil release more toxic gas and smoke. It is very necessary to research a flame retardant asphalt for the tunnel.
