The tail gas outlet nozzle should be tangential to allow gravity flow of the sulfur form the waste heat boiler to the inlet channel of the downstream sulfur condenser.

尾气出口喷嘴宜为正切向，从而使的来自余热锅炉硫的重力流流入下游硫冷凝器的入口通道。

Calculations showed that: with the guide vanes, the high-pressure water would have tangential velocity after it went through the nozzle and form more obvious swirling jet.

计算结果表明：使用导流叶片后，高压水通过喷嘴后具有了切向速度，并形成了较为明显的旋转射流。

In tangential combustion system, the reheat steam temperature can be adjusted by changing burner nozzle Angle to just the flame position.

在切向燃烧系统中，通过改变燃烧器喷口的角度可以调节炉内火焰中心位置，可达到调节再热汽温的目的。
