Continuous Blowdown Expansion Tank

The continuous blowdown flash tank is connected to the boiler’s continuous blowdown outlet and serves to reduce the pressure and expand the volume of the boiler’s continuous blowdown before discharging it. The secondary steam is routed through a dedicated pipeline, typically to the deaerator, while the waste hot water is automatically discharged via a float‑type level control valve or an overflow‑adjustment valve, usually into a fixed‑drain flash tank, allowing the thermal energy to be recovered and reused. The continuous blowdown flow rate is automatically adjusted in response to changes in the boiler feedwater load, maintaining a relatively stable blowdown rate. By utilizing the secondary steam and waste hot water as heat sources, a portion of the heat lost in the boiler’s continuous blowdown can be recovered, thereby improving boiler efficiency.

Regular blowdown expansion tank

The periodic blowdown expansion tank reduces the pressure and expands the volume of boiler blowdown water, thereby separating secondary steam from waste hot water. The secondary steam is discharged to the atmosphere or utilized as a heat source, while the waste hot water is typically routed to an effluent cooling pond and then discharged into the groundwater system.

Good News

Good News: The high‑frequency start‑stop high‑pressure heater, low‑pressure heater, and headless built‑in deaerator equipment we designed and supplied for the South African Redstone 100 MW concentrated solar power project have successfully achieved stable full‑load operation at a net output of 100 MW, with all system parameters meeting excellent performance standards. This marks another milestone breakthrough for our company in the African CSP market, following our earlier successes on Morocco’s Noor 200 MW and 150 MW CSP projects.
