Based on research by energy industry experts in the healthcare sector,
1.1.2 Boiler " A boiler generates steam at the desired pressure and temperature by burning fuel in its furnace. Boilers are used in both fossil-fuel and nuclear-fuel electric generating power stations. A boiler is a complex integration of furnace, super heater, reheater, boiler or evaporator, economizer, and air
device is located on the boiler breeching (the large pipe which connects the boiler to the chimney). In larger heating plants, installation of this device is required by the Department of Environmental Protection - Bureau of Air Resources. It is my opinion that all oil fired heating systems, regardless of size, should be equipped with this device.
The principal cause of mineral scale formation in boilers is the fact that scale-forming salt solubility decreases with increasing temperature. Thus, as boiler water is heated, the solubility of scale-forming salts is exceeded and crystallization takes place on the boiler heating surfaces.
