condensing boiler formula

Condensing boiler - Wikipedia

Condensing boiler. Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation,

Choosing A New Boiler - SimplifyDIY - DIY and Home

Condensing boilers Available as both regular and combination boilers, condensing boilers are more energy efficient than standard boilers as less heat is lost through the flue to the outside. They operate in exactly the same way as a regular boiler, and require the same fixings/equipment/treatment as a regular boiler.

Boiler Horsepower - Engineering ToolBox

Boiler horsepower - a power unit from the 19 th-20 th centuries - was used to rate the capacity of a boiler to deliver steam to steam engines.. A common definition of one boiler horsepower is the amount of energy required to produce 34.5 pounds (15.65 kg) of steam per hour at pressure and temperature 0 psig (0 bar) and 212 o F (100 o C) - with feed water at pressure 0 psig and temperature 212 o F.

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.

Maximizing Small-Boiler Efficiency | HPAC Engineering

The second point relates to the fact that the efficiency of a condensing boiler increases as load decreases. A boiler receiving 90-F return water and operating at 100-percent load has a thermal efficiency of about 90 percent (Figure 1). For the same boiler operating at 25-percent load, efficiency increases to nearly 97 percent.
