70% to passThe time taken to raise steam on a cold boiler should always be _______________.
Anot less than a full 24 hours
Bthe time specified by the boiler manufacturer
Cnot more than 1 full hour
Das short as possible to avoid excessive thermal expansion
AI Explanation
The correct answer is B) the time specified by the boiler manufacturer. The time taken to raise steam on a cold boiler should be the time specified by the boiler manufacturer. This is because the boiler manufacturer has carefully designed the boiler and determined the appropriate time and procedure for safely raising steam pressure from a cold start. Rushing the process (option D) or arbitrarily setting a 24-hour minimum (option A) could lead to excessive thermal expansion or other issues that could damage the boiler. Option C of limiting to 1 hour is too restrictive and may not allow for the proper, safe boiler warm-up as specified by the manufacturer.
