Boiler Efficiency Stack Losses for No 2 Oil

HSB Equipment Efficiency Calculators About These Calculators

The single largest boiler efficiency loss is the heat that exits the stack. The heat loss out of the stack is directly related to the quantity of gas that exits the stack. A reduction of module is based on an assumed minimum excess air of 10% for natural gas and 15% for No. 2 oil utilizing existing equipment. New burners or controls may

Stack temperature question — Heating Help: The Wall

May 13, 2006 · Does the higher stack temp mean the water in the boiler will heat quicker and reduce burner run time? Or am I going to have increased standby heat loss which will increase fuel usage? What do you think about these numbers? old numbers o2=6.5, co2=10.7, stack=450, ea=42, draft=-0.005 new numbers o2=6.8, co2=10.5, stack=530, ea=44.7, draft=-0.09

AFUE and Real Boiler Efficiency - High Efficiency Oil and

AFUE is the prescribed method for heat only boilers, although it is not much different than combustion efficiency which measures stack related losses. Typical boiler efficiency is routinely much lower than AFUE or combustion efficiency, especially for cast iron boilers or boilers with high "mass" and less than 2" of insulation, and for

Flue Temperature - an overview | ScienceDirect Topics

The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature. • Insulate the jacket of the boiler to reduce heat losses. The improvement of the boiler efficiency depends on the surface
