Study Notes
Boiler Requirements
- A feedwater regulator is not required for a hot water heating boiler.
- Feedwater regulators can reduce the amount of water wasted and the amount of energy wasted.
ASME BPVC IV Requirements
- ASME BPVC IV does not require a stop valve in the steam outlet for single steam heating boiler systems.
Boiler System Operation
- Low-pressure steam heating boilers controlled by an outside air temperature sensor may cycle on and off frequently during the spring or fall months.
- A vacuum breaker in a boiler system prevents the formation of a vacuum, which can cause damage to the boiler.
- A drum vent valve is typically located in the top of the boiler drum.
- The drum vent valve releases non-condensable gases and prevents a buildup of pressure in the boiler drum.
- Non-condensable dissolved gases entering the main steam system can reduce the efficiency of the system and cause damage to the equipment.
Boiler Fittings
- A stop valve in the return pipe connection for single steam heating boiler systems prevents water from flowing back into the boiler when the system is shut down.
- An air separator in the supply line to the heating system for hot water heating boilers removes air from the system, which can cause noise and reduce efficiency.
- A non-code fitting for a hot water heating boiler is a fitting that is not required by the ASME BPVC IV.
Low-Pressure Steam Heating Boiler Requirements
- Low-pressure steam heating boilers are not required to have a steam separator.
Function of a Vacuum Breaker
- A vacuum breaker prevents the formation of a vacuum, which can cause damage to the boiler.
Where is a Drum Vent Valve Located?
- A drum vent valve is typically located in the top of the boiler drum.
Function of a Drum Vent Valve
- The drum vent valve releases non-condensable gases and prevents a buildup of pressure in the boiler drum.
