Fuel Type: Boilers can be fueled by a variety of sources, including natural gas, propane, oil, coal, and biomass.
Heating Surface: This is the area of the boiler where heat is transferred to the water or steam. It is usually measured in square feet or square meters.
Capacity: This is the amount of steam or hot water that the boiler can produce. It is usually measured in pounds or kilograms per hour.
Pressure: The pressure inside the boiler is typically measured in pounds per square inch (psi) or kilopascals (kPa).
Efficiency: This is the percentage of the fuel energy that is converted into usable heat. Boiler efficiency can vary widely depending on the type of boiler and its operating conditions.
Temperature: Boilers can generate steam or hot water at a wide range of temperatures, depending on the application.
Safety Features: Boilers are equipped with various safety features to prevent accidents and ensure safe operation, such as pressure relief valves, low-water cutoff switches, and flame sensors.
