Boiler auxiliary equipment - continuous blowdown expander

Boiler auxiliary equipment - Continuous blowdown expander is connected to the continuous blowdown port of the boiler, which is used to reduce the pressure and expand the volume of the boiler's continuous blowdown. The blowdown water is adiabatically expanded and separated into secondary steam and wastewater in the continuous blowdown expander. After expansion, pressure reduction, and heat exchange in the expander, it is discharged. The secondary steam is led out by a special pipe, and the wastewater is automatically discharged through a float level valve or overflow regulating valve. The thermal energy can be recovered and reused. The continuous blowdown amount is automatically adjusted with the change of boiler feedwater load to maintain a relatively stable blowdown rate.

Product Use
The continuous blowdown expansion tank expands and separates the continuous blowdown water from the boiler, separating steam and water. The heat from the steam and water is used as a heat source for heating, improving the boiler's heat utilization efficiency.
