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。

The flue gas residual swirling at furnace outlet is considered as an essential problem for tangential firing boiler.
炉膛出口气流残余旋转被认为是切向燃烧锅炉的固有问题。

It is confirmed that, the operation level of stoker boilers can be improved such as enhancing the combustion intensity, boiler thermal efficiency and flue gas temperature of furnace outlet.
