The Basics of a Boiler Stack Economiz

Normally in the 2.0 – 4.0% range. In the case where there is a cold water makeup stream (50-55 deg. F°) of at least 25% of the boilers’evaporation rate, the efficiency gain can be more. To figure this, you begin by calculating the flow to the economizer. Use 34.5 pounds of steam per boiler horsepower and a gallon of water weighs 8.3 pounds.

Efficiency of new steam boiler vs. old — Heating Help: The .

If the boiler is square, its efficiency will probably be better. If the burner is a high-efficiency model and the installer placed suitable baffles in the boiler's flue passages, you might see a high-70's efficiency. Once the boiler has generated the steam, its job is done. From that point, the system must move the heat to the radiators.
