What are try cocks used for in steam boilers?

• A. Regulate steam pressure
• B. Find the height of water in the boiler
• C. Test boiler efficiency
• D. Check boiler temperature

Answer: (B)

Try cocks are vital components in steam boilers used specifically to measure the water level inside the boiler. By opening a try cock, a technician can observe the water level directly through the valve. This is crucial for ensuring that the water level is within the safe operating range; too little water can lead to overheating and damage to the boiler, while too much water can cause inefficient steam production and even water carryover. This direct measurement method provides an immediate way to assess the boiler's water level, which is essential for safe and efficient boiler operation. The other options focus on aspects like steam pressure regulation, efficiency testing, and temperature monitoring, which are not the primary functions of try cocks.
