For HTAC (Hight Temperature Air combustion) technology, pressure control and pressure fluctuation during combustion switchover are very important to the furnace reliability and stability.

蓄热式燃烧技术中，炉压控制和换向时造成的炉压波动是一个非常重要的问题。

In technology, the pressure and the hight of interface between oil and water are required to keep a certain value.

这在工艺上，要求其油水界面高度及罐顶压力保持一定数值。
