Steam Radiators vs. Hot Water Radiators - The Spruce

Steam is driven through it, fills the radiators, and then condenses and runs back down that same pipe in the form of water. The water is recycled and used again in the next cycle. Two-Pipe System: In the two-pipe radiator system, one pipe delivers steam to the radiators and a second pipe separately returns condensed water to the furnace.

Steam and Condensate - A basic overview of a steam system

Steam passes from the boiler into the steam mains. Initially the pipework is cold and heat is transferred to it from the steam. The air surrounding the pipes is also cooler than the steam, so the pipework will begin to lose heat to the air. Insulation fitted around the pipe will reduce this heat loss considerably.

BASIC WATER TREATMENT OF STEAM BOILERS

of the makeup water. For example, the makeup water chloride concentration is 10ppm so the boiler chloride concentration must never exceed 100ppm. The only way to control the cycles of concentration in boilers is to remove (blow down) some of the highly concentrated boiler water. Makeup water replaces blow down and dilutes the remaining boiler water.
