🔍 Key Concepts

• Thermal stress in boiler pressure parts when heating too quickly • Role of the boiler manufacturer’s procedures and manuals • Why slow, controlled warming is important for a cold boiler

💭 Think About

• Which option best reflects a controlled, safe, and manufacturer‑based procedure rather than an arbitrary time limit? • What could happen to boiler drums, tubes, and stays if steam is raised too quickly from cold? • Does any choice mention a source that would normally define safe warm‑up rates and procedures for that specific boiler design?

✅ Before You Answer

• Check which answer places emphasis on following documented, specific procedures instead of a fixed generic time. • Eliminate any option that could encourage rushing steam raising from a cold condition. • Consider which choice aligns with standard practice in reducing thermal shock and protecting boiler structure.
