New York Low Pressure Boiler COF Practice

What is the steam pressure limit related to the combustion regulator in a low pressure boiler?

1. 10 psig

2. 12 psig

3. 15 psig

4. 20 psig

The correct answer is: 15 psig

In a low pressure boiler, the steam pressure limit set by the combustion regulator is typically established at 15 psig. This is due to regulatory standards and safety protocols that govern the operation of low pressure steam systems. The combustion regulator is crucial for controlling the amount of fuel being supplied to the burner based on the steam pressure within the system. Operating at or below this pressure limit ensures that the system remains within the safe operating parameters, reducing the risk of over-pressurization and potential hazardous situations. Keeping the steam pressure at or below 15 psig helps maintain efficient combustion while safeguarding the structural integrity of the boiler and associated piping systems. Understanding these limits is essential for anyone managing or operating a low pressure boiler, thereby ensuring compliance with safety regulations and effective system performance.
