   However, the variable price of oil on world markets leads to erratic and high prices compared to some other energy sources. Institutional heating systems (office buildings or schools, for example) can use low-grade, inexpensive bunker fuel to run their heating plants, but capital cost is high compared to more easily managed liquid fuels.

   In the United States, federal licensure is generally handled by EPA certified (for installation and service of HVAC devices). Many U.S. states have licensing for boiler operation. Some of these are listed as follows: Arkansas [46] Georgia [47] Michigan [48] Minnesota [49] Montana [50] New Jersey [51] North Dakota [52] Ohio [53] Oklahoma [54 ...

4. Condensing boiler - Wikipedia

   en.wikipedia.org/wiki/Condensing_boiler

   Condensing boiler manufacturers claim that up to 98% thermal efficiency can be achieved, [3] compared to 70%–80% with conventional designs (based on the higher heating value of fuels). Typical models offer efficiencies around 90%, which brings most brands of condensing gas boiler in to the highest available categories for energy efficiency.

8. Boiler - Wikipedia

   en.wikipedia.org/wiki/Boiler

   Early boilers provided this stream of air, or draught, through the natural action of convection in a chimney connected to the exhaust of the combustion chamber. Since the heated flue gas is less dense than the ambient air surrounding the boiler, the flue gas rises in the chimney, pulling denser, fresh air into the combustion chamber. [citation ...

9. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   The steam piping (with steam flowing through it) is directed through the flue gas path in the boiler furnace. This area typically is between 1,300–1,600 °C (2,372–2,912 °F ). Some superheaters are radiant type (absorb heat by thermal radiation ), others are convection type (absorb heat via a fluid i.e. gas) and some are a combination of ...
