New York Low Pressure Boiler COF Practice

If an electric boiler is operating at a maximum of 1100 kW, how many safety valves must be installed?

1. 1

2. 2

3. 3

4. 4

The correct answer is: 2

The correct answer reflects the safety requirements for boiler systems, particularly in New York. When calculating the number of safety valves needed, it is important to consider the maximum output capacity of the boiler, which in this case is 1100 kW. According to regulatory guidelines, a boiler operating within certain capacity thresholds requires a specific number of safety valves to ensure safe operation. Each safety valve is required to relieve excess pressure and maintain system integrity, particularly under maximum operational loads. For electric boilers, the rule typically states that for every 1000 kW of output capacity, a certain number needs to be installed. Since the boiler in question is rated at 1100 kW, it generally falls into a category where two safety valves would be mandated to provide adequate safety coverage. This number helps ensure that if one valve fails, the second valve can still provide the necessary pressure relief, thereby preventing potential overpressure situations that could lead to hazardous conditions. Understanding these requirements is vital for compliance with safety regulations and ensuring the reliability of the boiler operation.
