CHAPTER 3 STEAM DISTRIBUTION SYSTEMS
EXTERIOR STEAM DISTRIBUTION SYSTEMS
Underground and aboveground.
Their high cost of installation.
High cost of maintenance.
INTERIOR STEAM DISTRIBUTION SYSTEMS
Inhibits emission of heat from the heating system.
A return trap system has a gravity return and a condensate pump
system has a forced return.
Withdraws air and water from the system, separates them, expels
the air, and pumps the water back to the boiler.
STEAM DISTRIBUTION SYSTEM COMPONENTS
Fin-tube and cast iron.
10°F or lower than that of the water.
Upright or standard, and inverted.
The bellows develops holes.
