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.
I believe that is 15 PSI on a low pressure steam boiler
Typical heating boiler setpoint is around 180*, if you are looking to economize, look into having a reset control installed. The reset control will adjust the boiler setpoint based on outdoor air temperature. On a 70* day you would have 70* boiler water temp with a reset schedule of 1.5, for every degree outdoor temp drops below 70 the boiler temp would rise 1.5* so on a 0* day, boiler temp would be 175*. The reset schedules are adjustable.
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
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.
Of course it can fail. Look at the temperature of the water in the boiler, turn the stat up and down. You should hear a slight click when the temperature setting and the boiler water temp are appx the same if you do, the stat is probably good. You can verify this with a voltmeter.
