Industrial Boiler Efficiency Calculation & Factors
This is why oil fires operate at higher efficiency levels than natural gas. Turndown. Turndown is the ability of the boiler to achieve a wide range (from low to high) of output. If a boiler has a high turndown ratio, then it is able to supply steam at lower rates without shutting down and restarting.

Natural Gas Vs Fuel Oil Vs Propane: The
In other words, natural gas (methane) is to gas fossil fuels what lignite is to coal. But, for the 50 years prior to 2008, natural gas was always more expensive, considerably, than fuel oil. Only with advancements in hydrofracking technology and massive drilling efforts through the Mountain West and Desert Southwest since 2005 did that change.
