🔍 Key Concepts

• Boiler cut-in procedures when bringing an idle boiler online with another boiler already in service • Purpose of superheater vents and air cocks during warm-up and pressurization • Why we compare pressures between the idle boiler and the header/main steam line before changing valve or firing conditions

💭 Think About

• Think about what could happen if you connect a boiler to a steam line while its pressure is still significantly different from the line pressure. Which action relates directly to safely matching pressures? • Consider the functions of the superheater vent and air cock: when are they open, and what condition must be met before you change their status? • At only about 5 psi above the pressure of the boiler already on the line, is it more important to increase firing, equalize pressure, or change venting conditions?

✅ Before You Answer

• Identify which choice directly relates to matching boiler pressure to the line/header pressure for safe connection. • Recall that vents and air cocks are typically used to remove air and prevent condensation shocks—decide at what point in the warm-up process they are usually closed. • Ask yourself which option, if done too early, could create a dangerous pressure differential or thermal stress between the two boilers.
