Efficient Boiler Design • Combustion Efficiency – 100 percent of efficiency minus the percentage of heat lost up the vent. • Thermal Efficiency – The combustion efficiency minus the jacket losses of the boiler. Based on ANSI Z21.13. For boilers 300,000 to 12.5 million Btu. • A.F.U.E. – The measure of annual efficiency of a boiler

What are the Differences Between Intermittent Bottom

Boiler modulation is the ability of a boiler to 'turn down' its output. That is to say if you have a 20kw boiler, but you only require 10kw of heat for the next hour, rather than outputting 20kw for 5 minutes then resting 5 minutes repeatedly, (how the older non-modulating boilers used to work) the boiler will simply turn down its flame by 50%.

The ton ratings you see here have nothing to do with the weight of the unit. In fact a ton is simply 12,000 BTUs (see BTU definition on this page). A typical home cooling/heating system uses heat pumps or air conditioners with a capacity of between 1.5 and 5 tons.

The results showed that model two provided a suitable and stable outcome without losing a lot of computational power. Moreover, the included wall capacitance is visible. The disadvantage of this model is the complexity in comparison with the current model. Keywords: Simulation, Dynamic model, Heat exchanger, Programming II
