AFUE and Real Boiler Efficiency | Annual Fuel Utilization Efficiency

There's virtually no energy left to waste. Thermal purge must be combined with a low mass boiler (not a cast iron boiler), so there's not too much heat energy left in the boiler when the burner finishes running. This type of thermal purge anticipates the end of the

Stratification most commonly occurs in sloped tubes (Figure 14-7) located away from the radiant heat zone of the boiler, where heat input is low and positive circulation in the tubes may be lacking. Examination of the affected tubes usually reveals a prominent water line with general thinning in the top area of the tube or crown.

Waste heat recovery | energy.gov.au

Waste heat as low as 45°C can easily be recovered by special heat pumps to produce output temperatures in excess of 100°C, suitable for commercial and industrial applications traditionally dependent on gas for heating. Use of heat pumps may even prove a stepping stone towards complete replacement of boilers and steam systems in the long term.
