the effective range in which it can be used; ie the temperature ranges of operation
A boiler is primarily used for heating. Water is heated and forced through pipes to heating receptacles called radiators. Giant boilers are also used for electricity. Water is heated to turn giant turbines that produce electricity.
An IK on a boiler is a Soot Blow. It is mounted on the sidewall of a boiler furnace and cleans the internal boiler parts with high pressure.
What you meant by this question is uncertain. If you are asking about the definition then Boiler steam pressure is the pressure developed by a water steam boiler, else if you are asking about the Rated boiler steam pressure then it is the safe operating pressure a boiler can operate, else if you are asking about Maximum boiler steam pressure then it is the maximum pressure that a boiler can produce with out failure.
ATMOSPHERIC BOILERa boiler on which combustion air/flue gases are drawn through the boiler without a fan.(Taken directly from the Crown Boiler Co. web-site.)
It is a type of boiler that you can use in your business. There are many different types that you can choose from.
afbc has high turn down ratio,burner arrangement is simple,low grade coal can be burnt efficiently,so2 emission can be controlled,
circulation ration of boiler is defined as ratio of Mass of Steam/water mixture to steam generation.
turndown ratio
5\9
it is ratio of maximum air to minium air
Call the water board, if you can't turn the pressure down on the boiler.
Blow down is done in the boiler in case level is high in the boiler
Of course it can fail. Look at the temperature of the water in the boiler, turn the stat up and down. You should hear a slight click when the temperature setting and the boiler water temp are appx the same if you do, the stat is probably good. You can verify this with a voltmeter.
If you are using water and not steam there should be a temperature controller mounted in the side of the boiler, that is where the start and stop point of the boiler is controlled.

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
In the combo boiler for the central heating? You need a small piece of hose (or it might have a permanent connection) to fix to the mains from the boiler. Then turn the taps near the boiler for the mains and the boiler. You want the pressure to be about 1.3 bar
