boiler efficiency is how much water is converting to steam.
A damper in a boiler is a device that regulates air flow into the combustion chamber. It helps control the amount of oxygen available for combustion, thereby maintaining the desired temperature and efficiency of the boiler. By adjusting the damper, the operator can fine-tune the combustion process for optimal performance.
Cfbc stands for circulating fludised bed combustion where as afbc is for atmospheric fluidise bed combustion afbc bed fluidising velocity is approx 4 m/s and in cfbc boiler fluidising velocity is 9-10 m/s. cfbc having low SOx & NOx comparative with afbc cfbc having higher efficiency up to 98.5 % then afbc boiler,cfbc boiler power consumption is more comparative to afbc.
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.
No, a boiler is not an internal combustion engine. A boiler is a closed vessel that uses heat to generate steam or hot water for heating or power. Internal combustion engines, on the other hand, are machines that generate power by burning fuel within a combustion chamber.

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.

Atmospheric Fluidized Bed Combustion Boiler (AFBC boiler) is a type of operational boiler. In a AFBC boiler a little more fluidized bed combustor is added than a conventional shell 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.
