Back Flow The Boiler

Steam and Condensate - A basic overview of a steam

2019-11-11 · The flow of steam to the plant. When steam condenses, its volume is dramatically reduced, which results in a localised reduction in pressure. This pressure drop through the system creates the flow of steam through the pipes. The steam generated in the boiler must be conveyed through the pipework to the point where its heat energy is required.

How to Calculate Boiler Steam Flows | Hunker

This would in turn yield a total flow of 2,628.1 lb/hr of steam. Therefore, knowing the amount of combustion air flow during an hour for a given boiler, you can back-calculate to compute the steam flow. This means a boiler will produce about 2,628.1 lb/hr / 2,289 lb/hr of combustion air consumed, or about 1.15 pounds of steam for every pound of
