To convert boiler heating surface to horsepower, you can use the formula that one horsepower is equivalent to approximately 10 square feet of heating surface. Therefore, you would divide the total heating surface area (in square feet) by 10. For example, if a boiler has 100 square feet of heating surface, it would be equivalent to about 10 horsepower. Keep in mind that this is a rough conversion, as actual performance can vary based on boiler efficiency and other factors.
Pump efficiency can not be taken as given.
A 5-ton boiler refers to a steam or hot water boiler's capacity to produce 5 tons of steam or heated water per hour. This measurement indicates the boiler's efficiency and output, with one ton of steam being equivalent to 2,000 pounds of steam per hour. Such boilers are commonly used in industrial applications for heating, power generation, or process heating. The term "ton" is derived from the amount of cooling or heating capacity required to raise or lower the temperature of water in a specified time.
For a Worcester oil boiler with an output of 140,000 BTU, you typically need a nozzle size of around 0.85 to 1.0 gallons per hour (GPH), depending on the specific model and efficiency requirements. It's essential to consult the boiler's manual or a heating professional to determine the exact size and type of nozzle required for optimal performance. Proper nozzle selection ensures efficient combustion and helps maintain the boiler's efficiency and longevity.
Boiler can be classified as below
boiler efficiency is how much water is converting to steam.
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.
Boiler power is not determined in megawatts. A boiler horsepower is determined as 33000 btus. That is equivalent to 34.5 pounds of steam from and at 212 F. Conversion of boiler conditions (factor of evaporation) output and horsepower to atmospheric steam conditions is the norm for determining boiler horsepower. The ASME code contains several methods for determining boiler horsepower. Megawatts are a determination of turbine-generator output.
Boiler feed is the fresh or treated water to replenish the water loss though evaporation or leak
There are many factors. First of all, there is the temperature of the water. Next, the is the volume of water. Next there is the amount of pressure gradually built up in the boiler. Next you have the amount and speed at which heat is transferred to the water.

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 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.
