But for an instantaneous fuel consumption rate, the thermal efficiency may be better. The theoretical limit for a conventional furnace's instantaneous efficiency is 100%, whereas a heat pump used for building heating may exceed 100%. For example, a COP of 1.5 is equivalent to 150%. Heat pumps are readily available for electric and gas sources. [3]
FI = emissions intensity of fuel = 50 kg(CO 2)/GJ for natural gas, 73 for heating oil, 0 for 100% renewable energy such as wind, hydro, photovoltaic or solar thermal; AFUE = furnace efficiency ≈ 95% for a modern condensing furnace; COP = heat pump coefficient of performance ≈ 3.2 seasonally adjusted for northern US heat pump
An oil burner is a part attached to an oil furnace, water heater, or boiler. [1] It provides the ignition of heating oil/biodiesel fuel used to heat either air or water via a heat exchanger . The fuel is atomized into a fine spray usually by forcing it under pressure through a nozzle which gives the resulting flame a specific flow rate, angle ...
#2 Heating oil price, 1986–2022 Kerosene inventory stock levels (United States), 1993–2022. Heating oil is known in the United States as No. 2 heating oil. In the U.S., it must conform to ASTM standard D396. Diesel and kerosene, while often confused as being similar or identical, must each conform to their respective ASTM standards. [3]
R-410A is a mixture of 50% HFC-32 and 50% HFC-125. HFC-32 has a 4.9 year lifetime and a 100-year GWP of 675 and HFC-125 has a 29-year lifetime and a 100-year GWP of 3500. [ 10 ] [ 11 ] The combination has an effective GWP of 2088, higher than that of R-22 (100-year GWP = 1810), and an atmospheric lifetime of nearly 30 years compared with the 12 ...

The emissions from ships have generally been controlled by the following sulfur caps on any fuel oil used on board: 3.50% on and after 1 January 2012 and 0.50% on and after 1 January 2020. [25] Further removal of sulfur translates to additional energy and capital costs [26] and can impact fuel price and availability. If priced correctly the ...
