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.
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.

The SEER metric is used to measure a heating and cooling systems performance, which is determined largely by the HVAC equipment operating efficiency. SEER stands for Seasonal Energy Efficiency Rating.
boiler efficiency is how much water is converting to steam.
The SEDBUK rating is an energy efficiency rating developed by the UK government and used in the boiler industry. It is used to provide a comparison between different models of boilers and different manufacturers.
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.
Efficiency rating: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G

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.

There is a wide variety of electric boiler ratings. This is because an electric boiler rating is based on the square foot area of the heating coils. The larger the system the more heating power will be needed.
Efficiency rating: ((PTS + REB + AST + STL + BLK) - ((FGA - FGM) + (FTA - FTM) + TO)) / G
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.
