Energy in fuel enters the boiler (energy input 100 percent). From the boiler, 4 percent of heat loss is through radiation and convection, 18 percent is in flue gasses and 3 percent is in blowdown. Energy in heating medium (e.g. steam) exits the boiler. Energy output (boiler thermal efficiency) is between 75 and 77 percent.Get Price
The "A" design has two small lower drums and a larger upper drum for steam-water separation. In the "D" design, which is the most common, the unit has two drums and a large-volume combustion chamber. The orientation of the tubes in a "D" boiler creates either a left or right-handed configuration. For the "O" design, the boiler tubeGet Price

Boiler Systems Pump Selection Typical modern boilers will fire natural gas as the primary fuel, with a percentage of these using #2 fuel oil as a backup fuel. A system designer should be aware of a couple of key points when in-volved with boiler fuel oil systems. 1) Most boilers firing fuel oil will have their own fuel oil pump.Get Price
