Boiler Efficiency & Combustion Efficiency

Combustion efficiency – the importance of flue gas temperature and excess oxygen. The flue gas temperature across a firing range will vary from boiler to boiler. A true three pass design will generally have lower flue gas temperatures and a greater heat transfer surface. Boiler insulation will also have an impact on radiated losses.
