How Do Steam or Hot Water Furnaces Work? | AirNow HVAC

When circulation was started by initial firing or the circulating pump, the cold-water interface is moved upward through the walls, rapidly cooling the tubes. As the cooler water moves up the furnace its temperature gradient is decreased and as such the rate of cooling is decreased, therefore reducing damage higher in the furnace.

Converting steam systems to hot water – a new approach

A high pressure watertube boiler (also spelled water-tube and water tube) is a type of boiler in which water circulates in tubes heated externally by the fire. Fuel is burned inside the furnace, creating hot gas which boils water in the steam-generating tubes.In smaller boilers, additional generating tubes are separate in the furnace, while larger utility boilers rely on the water-filled tubes

Boiler Cycling Considerations - Babcock & Wilcox

Circulation refers here to the flow of water, steam, or their mixture around the steam—water circuit in a boiler. In early days of boilers, steam was generated in a large vessel. The vessel was heated from outside, which would create a convective current within the large body of water. This process did not pose any threat to the safety of the boiler. So a detailed knowledge of steam—water circulation or flow …
