Modelling experiments indicate that the new concept is able to enhance the bottom pressure in hearth so as to make the longitudinal pressure distribution more uniform.
模拟实验表明：新方案可以提高炉膛下部的压力，使炉长方向压力分布趋于均匀。
When the compression stroke is finished, the longitudinal pressure relief grooves are communicated with the air exhaust hole to release the high pressure.
当压缩行程完成时纵向泄压凹槽与排气孔相通，实现高压被释放的目的。
