What is the maximum output for an electric boiler that has one safety valve?

  1. Less than 500 kW

  2. Less than 1100 kW

  3. Less than 1500 kW

  4. Less than 2000 kW

The correct answer is: Less than 1100 kW

The maximum output for an electric boiler that has one safety valve is less than 1100 kW. This limitation is established to ensure safe operation and proper handling of the pressure generated by the boiler. The reason for this restriction is primarily related to safety and regulatory standards that are designed to mitigate the risks associated with high-pressure steam systems. When a boiler operates above certain output thresholds, it becomes necessary to implement additional safety systems and protocols, including multiple safety valves, to manage the potential hazards effectively. A boiler with a single safety valve is typically constrained in capacity as a precautionary measure to minimize the risk of overpressure situations. Operating an electric boiler under the limit of 1100 kW with one safety valve allows for a balance between efficiency, safety, and compliance with industry regulations. This ensures that the system can operate reliably without excessive risk to personnel or infrastructure.
