thermal gradient

用法例句

The vortex engine technique used in coal mine using gas to generate electricity takes advantage of the gas density lower than the other fuel,uses porous medium to premixed combustion,and then heats the air with the generated fuel gas,utilizes the air characteristics of hot-to-ascend and cold-to-descend,and cold and hot convection to form vortex which drive the turbine to generate electricity.

在煤矿瓦斯发电中的涡旋引擎技术,利用瓦斯浓度低于其它燃料的特点,使用多孔介质预混燃烧,产生的燃气加热空气,利用空气的热升冷降及冷热对流的特性,形成涡旋,带动涡轮机发电。
