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 efficiency rating of your boiler can typically be found on the manufacturer's label or in the user manual, which often specifies the Annual Fuel Utilization Efficiency (AFUE) percentage. You can also check online for the model number to access detailed specifications. Additionally, energy performance certificates or service records may provide insights into the boiler's efficiency rating. If in doubt, consulting a qualified technician can help determine its efficiency.

This question can't be answered. It is unclear what you mean by back pressure. Maximum Allowable Working Pressure in a boiler is calculated using the rules for construction of high pressure boilers and construction of heating boilers in the ASME Code sections 1 and 8.
boiler efficiency is how much water is converting to steam.
Pump efficiency can not be taken as given.
The efficiency of the boiler is calculated as the ratio of useful energy output (100J) to the total energy input (111J), which is then multiplied by 100 to get the percentage. So, efficiency = (100/111) * 100 = 90.09%.

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.

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.
To choose the best Combi Boiler, consider efficiency, output, and warranty. Boiler Hut can help you select the right one.
Back boilers are outdated and no longer recommended. Boiler Hut advises installing a modern boiler for better efficiency and safety.
The full form of BECR in the context of boilers is "Boiler Efficiency and Combustion Research." This term typically relates to studies and analyses aimed at improving the efficiency and effectiveness of boiler operation, focusing on combustion processes and overall energy utilization.
