During a bottom blowdown, the boiler should be under light load and the water level should be at the NOWL. 8-The quick-opening valve is opened first when a quick-opening and slow-opening valve are used.The slow-opening valve is opened slowly to the full open position. The slow-opening valve takes the wear and tear of blowdown.

Use these valves for boiler maintenance and other low-pressure plumbing applications. They gradually open and close with multiple turns of the wheel handle to adjust and regulate flow. All have a rising stem that lifts as the valve opens and lowers as the valve closes to provide a visual indication of whether flow is on or off.. Flow coefficient (Cv) is the amount of water (in gallons per

Boiler Safety - OSHA

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of

A pipe near the bottom of the blowoff tank maintains a water level below the blowdown entry point and allows cooler water remaining from earlier blowdown events to drain from the tank first. Two bottom blowdown valves are often used in series to minimize erosion. One valve serves as the sealing valve, and the other as the blowdown valve.
