🔍 Key Concepts

• Function of a bottom blow on a boiler and why it’s done quickly or slowly • The sequence of valves in a boiler blowdown line: drum → first valve → second valve → overboard/skin valve • Difference between guarding valve and blow down valve in terms of safety and operation

💭 Think About

• Which valve is closest to the boiler pressure source, and how does that affect how you operate it? • In a bottom blow, do you want full, rapid flow right at the boiler, or do you first control flow further downstream? • Think about which valve is normally left open or closed in service, and which one is actually ‘cracked’ or spun during a blowdown.

✅ Before You Answer

• Verify the order of valves from the boiler water drum to overboard (first, second, last). • Confirm which valve is primarily used to control the blowdown flow vs. which acts mainly as a safety/isolating valve. • Check standard practice: which specific valve is explicitly described as being opened quickly and closed quickly during a bottom blow.
