Boiler ratings and boiler load - SlideShare

Sep 02, 2012· Boiler Ratings and Boiler Load The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam

Condensing Boilers Efficiency | U.S. Boiler Company

There are other requirements as well. Gas-fired boilers cannot have a pilot that constantly burns, and hot water boilers must be able to automatically adjust the water temperature to match the heat load. Another factor that impacts efficiency ratings depends on whether the boiler is a condensing model or a conventional non-condensing model.

Condensing Boiler - AHRI

Condensing boilers can achieve greater efficiencies because they capture more heat from the exhaust gases than a conventional boiler. To do this, a condensing boiler has a larger heat exchange surface to enable it to transfer as much heat as possible from the boiler's burner into usable heat, thereby allowing less heat to escape as exhaust gases.

Sizing a Steam Boiler | U.S. Boiler Company

Dec 05, 2017· Last month we discussed sizing a hot water boiler with a heat loss calculation. Unlike a hot water boiler, a steam boiler is sized by determining the square foot of radiation connected to the steam system. Once thats been determined, you can accurately select a boiler thats large enough to heat the connected load (radiation).
