2015-9-24 · Steam Blow-out procedure Operation of the boiler in sliding-pressure against the atmosphere. Steam-pressure emerges from loss of pressure of the super-heater system and the temporary steam blow piping system. Operating parameters: Steam-pressure between about 15 and 35 bar. Steam blow temperature should be between 480 and 525 °C.

Prevent boiler scale deposits and sediment buildup with these valves that meet ANSI and ASME standards for boiler drainage applications. They gradually open and close to prevent system damage from suddenly starting or stopping flow. Wheel handles open and close with multiple turns, providing more controlled, shock-resistant flow than lever handles.

In these cases, multiply the boiler pressure by 1.15 to calculate the blowdown rate from Figure 3.14.1. Blowdown lines over 7.5 m can be read straight from this graph. Example 3.14.1: For a boiler pressure of 10 bar g, an equivalent 40 mm blowdown line length is calculated to be 10 m, consequently, the blowdown rate is 6.2 kg/s (see Figure 3.14.1).
