Question

Why pressure gauge and safety valve are made use of in the Schmidt-Hartmann boiler?

(a) Safety against fire causes

(b) To control the burst/blast of the boiler due to variance in pressure

(c) Safe guard against leakage accidents

(d) Act as controller against overheating of water in the boiler and boiler tubes

I got this question in homework.

My question comes from Types of High Pressure Boilers topic in section Steam Generators & Accessories of Energy Engineering

Answer 1

The correct choice is (c) Safe guard against leakage accidents

To explain I would say: In normal circumstances, replenishment of distilled water in the primary circuit is not required as every care is taken in the design and construction to prevent leakages. But as a safeguard against leakage accidental loss, a pressure gauge and safety valve are fitted in the Schmidt-Hartmann boiler’s circuit.
