continuous blowdown expanders

it can retrieve partial lost quantity of heat of the continuous blowdown of boiler,increase the efficiency.

1. Overview

Continuous blowdown expanders are used to reduce pressure and dilatancy the continuous blowdown of boiler. The flash steam and waste heat water is used as heat source, it can retrieve partial lost quantity of heat of the continuous blowdown of boiler, increase the efficiency.

Explanation: according to users’ requirements, our company can specially design and make the other various models of continuous blowdown expanders for your factory. Please provide these when you order: working parameters such as working pressure, working temperature, geometric volume and so on. If you have special installation requirements, please put together.

3. Working process

The sewage water of boiler is continuous discharged into blowdown flash tank,the sewage water is tangential movement in cylinder clapboard in center of enclosure, and it is vaporized into flash steam. The flash steam after steam-water separating, then be discharged into deaerator from the exit on the top of contin blwdwn, the remaining sewerage is discharged by level control valve.
