it is ratio of maximum air to minium air
Turn down ratio is the maximum to minimum heat output.Turn down ratio for direct gas fired burners is 25:1, which means that the burner can modulate from 4% to 100% of full fire. Indirect gas turn down ratio is typically 2:1, which limits the heat output from 50% to 100% of full fire. Mukesh Yadav

The paddle wheeled river boats of Twain's day were wood fired steam boats, The wood was cut and piled near landings by local contractors. The boats were interesting sas the engineers on board were always screeing down the safeties on the boilers (no fire tubed boilers back then) and as a consequence the boilers, engineers and their boas would often explode.

It depends on what you wish to turn it into!
Yes, larger tires are harder to turn.
This is a number that indicates what range the transmitter will work correctly. This will depend on how strong the transmitter is.
Typically a transformer is designed for a specific turn ratio x:y the fact is that is only true if the power is held as designed for that ratio
In New Jersey, you can typically turn off your boilers during the warmer months, usually around late spring to early summer, once outdoor temperatures consistently remain above 60°F. However, local regulations may vary, so it's essential to check with your municipality or utility provider for specific guidelines. Additionally, ensure that you have adequately prepared and maintained your heating system before shutting it down for the season.
To turn a mixed number into a ratio, you must divide each number into a common denominator.
