Question 445Steam Plants - Assistant Engineer

The correct answer is B) prevent stressing of the safety valves. Proper bracing and support of the boiler safety valve escape piping is necessary to prevent stressing of the safety valves. The safety valves are critical components that must be able to open and close freely to relieve excess pressure in the boiler. If the escape piping is not properly supported, the weight of the piping or movement could put undue stress on the safety valves, potentially compromising their function. The other answer choices are incorrect. Preventing scale buildup (A), allowing for back pressure formation (C), and preventing condensate accumulation (D) are not the primary reasons for properly supporting the safety valve escape piping.
