减温减压装置是将蒸汽压力和温度降低至规定数值的一种（压力管道元件组合）装置。将高压蒸汽通过减压蒸汽调节阀进行节流调节，使蒸汽压力降至生产所需；将减温水雾化后喷入蒸汽中进行降温，使蒸汽温度降低至工艺要求。

It is a type (pressure pipe component combination) device that reduces the steam pressure and temperature to a specified value.

The high pressure steam is throttled through a vacuum steam regulating valve to reduce the pressure to the production; the desuperheated water is atomized and sprayed into the steam to cool down, so that the temperature is lowered to the process requirements.
