Heating Efficiency | EGEE 102: Energy Conservation and

The federal minimum-efficiency standards for furnaces and boilers took effect in 1992, requiring that new furnace units have an AFUE of at least 78 percent and new boiler units have an AFUE of at least 80 percent. In comparison, many old furnaces and boilers have AFUE ratings of only 55 to 65 percent.

Boilers - Reducing Fuel Costs In A Steam-Generating System

BOILERS REDUCING FUEL COSTS IN A STEAM-GENERATING SYSTEM savings and water conservation are more important to a facility's economics than ever before. Energy costs typically ac-count for as much as 60% of a facility's overhead, and the largest energy con-sumer is often the steam generating plant. Therefore, economics demand

Spray water group mass flow. Normally the mass flow rate of superheated steam (live steam) is known. Thus, mass flow rate calculations start usually by calculating the mass flow rate of spray water to the last spray water group (which is in this example between the second and third superheater stages).

How to Calculate Boiler Heat Input Rate | Sciencing

The boiler's heat input rate is proportional to the rate at which the temperature of the water within it rises. The factor relating these rates is the specific heat capacity of water. Subtract the water's initial temperature from its temperature at the end of the period whose input rate you are calculating.
