we can increase boiler efficiency by recovering the heat which is being carried by flue gases.by incorporating different things like Economizer, Air pre-heater , Super-heater and feed-water heater, we can there ll be notable increase in efficiency of boiler.

How is boiler efficiency calculated?
Boiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
What is efficiency of boiler?

What is the ratio of a boiler burner indicates the flexibility of the burner to cope with variations of boiler load without losing efficiency of atomisation?
turndown ratio
How do you increase the efficiency of a engine?
Lower it!
What leads to technology?
an increase to efficiency
What is the use of economiser in boiler?
The economizer is used to raise feedwater temperature up to nearly the temperature of the boiler to avoid thermal shock and improve the boiler's efficiency. Every 11 degrees Fahrenheit increase in feedwater temperature yields a 1% increase in boiler efficiency.
What is boiler combustion efficiency?
boiler efficiency is how much water is converting to steam.
How is boiler efficiency calculated?
Boiler efficiency is calculated by determining the steam value per hour and dividing it by the amount of fuel which is consumed per hour. By doing this one can determine the efficiency of a boiler.
How to increase a Thermal efficiency of rankine cycle?
-increase the temperature of the super heated steam -lowering the condensing pressure -increasing the boiler pressure (Reheating, regeneration...)
Difference between boiler mountings and accessories?
Boiler mountings are different fittings and devices which are necessary for the operation and safety of a boiler .e.g. pressure gauge, safety valves , steam stop valve etc Normally these device are mounted over boiler shell .Boiler Accessories are auxilary plants or parts required for steam boilers for their proper operation and to increase efficiency of the boiler .e.g.feed pumps, super heater , economiser etc

What is the function of economizer in bent tube boiler?
The flue gases, after leaving the main boiler and the superheater, will still be hot. The energy in these flue gases are used to preheat the already preheated feed water once more by means of the economizer. The economizer is a heat exchanger mounted in the first part of the chimney to improve the thermal efficiency of the boiler. In broad terms a 10°C increase in feed water temperature entering the boiler will give an efficiency improvement of 2% of last mentioned.
Why economiser is used in boiler?
An economizer is used to heat boiler feedwater up closer to the temperature of the boiler water, using heat from the boiler exhaust gases, heat that would otherwise be wasted. The main reason is to improve the efficiency of the boiler. For every 44 degree F drop in exhaust gas temp. there is an 11 F rise in feedwater temperature and a 1% gain in boiler efficiency.
Why boiler is operated close to critical temperature?
Greatest efficiency at that temperature.
