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.
1300 mmWc @ full load
Immediately the load on Generator should be reduced to Zero n desynchronised, and the turbine be tripped.
Benson point at which vertical steam separator run dry because entering water is converted completly to steam.
An auxiliary boiler is a secondary boiler used to support the main boiler in a steam power plant or marine vessel. It is often used when the main boiler is unable to meet the steam demands, providing additional steam capacity. Auxiliary boilers can also be used for heating purposes during maintenance or downtime of the main boiler.
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.
