Boiler load is the total "work" performed by the boiler. In residential application the boiler load usually refers to the total heat lost in a home on the coldest day of the year and is measured in the USA by British Thermal Units per hour.
To find the load the accepted practice is to use the "Manual 'J' method. Appropriate software and some experience is necessary to gain meaningful results and proper size a boiler to the load.
Boilers that are oversize use more fuel, suffer component failures and can create discomfort by lowering the average water temperature. Boilers sized below the load will not satisfy the thermostat on the coldest days of the year.

boiler are working on same principal but automatic and manual boiler has difference that manual boiler working at single element loop and automatic boiler work at three element loop.single loop means when fuel increase mean load increase on boiler by adjusting fuel operator has to adjust steam drum level manualy , while automatic means when load increas, fuel increase steam drum level adjust automaticaly by watching fuel consumption.
In order to determine what size boiler you need, you will need to have a Manual J Load Calculation performed on your home.
A boiler foundation is a structural base designed to support a boiler and its associated equipment. It must be robust enough to handle the weight and vibrations generated during operation, ensuring stability and safety. The foundation typically consists of reinforced concrete and is designed according to the specific load requirements and operational conditions of the boiler system. Proper foundation design is crucial for maintaining the efficiency and longevity of the boiler.

Immediately the load on Generator should be reduced to Zero n desynchronised, and the turbine be tripped.
To run a central heating boiler, a power generator with a capacity of at least 5 to 10 kilowatts (kW) is typically needed, depending on the boiler's size and efficiency. It's important to consider the boiler's electrical requirements, including any additional systems like pumps or controls. Always consult the boiler's specifications for precise power needs and ensure the generator can handle the starting load if the boiler has electric ignition. Additionally, a generator with a pure sine wave output is recommended for sensitive electronic components.
Benson point at which vertical steam separator run dry because entering water is converted completly to steam.
Boiler can be classified as below
remove load off transformer and check voltage.
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.
A high temperature in the boiler hot well can be caused by several factors, including inadequate cooling water supply, malfunctioning temperature sensors, or issues with the heat exchanger. Additionally, if the boiler is operating at a higher load than designed, it may lead to increased heat accumulation. Poor circulation of water within the system can also contribute to elevated temperatures. It’s important to monitor and address these issues to ensure safe and efficient boiler operation.
