Question 398Steam Plants - Assistant Engineer
70% to passWhich of the stated pressure conditions identifies the boiler design pressure?
AThe pressure specified by the manufacturer as a criterion for boiler design.
BThe pressure at which a boiler is operated during overload conditions.
CThe same pressure as the boiler operating pressure at full power capacity.
DA pressure lower than boiler operating pressure.
AI Explanation
The correct answer is A) The pressure specified by the manufacturer as a criterion for boiler design. The boiler design pressure is the maximum pressure the boiler is designed to withstand, as specified by the manufacturer. This is a critical parameter in the boiler's construction and safety. The boiler operating pressure at full power (option C) may be lower than the design pressure, while the pressure during overload conditions (option B) would exceed the normal operating pressure. Option D, a pressure lower than the operating pressure, does not accurately reflect the boiler design pressure.
