The heart of an industrial boiler system is a hot water or steam boiler operated with a certain kind of fuel. The boiler heats up or evaporates the water inside it, which is then transported to the consumers via pipe systems. In case of hot water the transport energy is generated by pumps, in case of steam the transport is based on inherent pressure.
Dirty boiler tubes can also affect the operation of a plant. Slag buildup on tubes will act as an insulation protecting the tube from the heat of the boiler, requiring more fuel to reach the same

Those boilers might be twice as large as a Midwest plant built to burn western coal and three or four times as large as plants built to burn eastern coal, many of which are being decommissioned
When a turbine becomes fouled with water-soluble salts as a result of boiler water carryover or attemperating water contamination, turbine capacity can often be restored by water washing. Because it can cause severe turbine damage, water washing should be supervised carefully and the recommendations of the turbine vendor should be followed.
Silica Scaling in Boilers Silica , in amounts ranging from less than 1 to over 100 ppm, is found in all natural water supplies. In rain hail and snow, silica content range from 1 to 2.8 ppm.
Steam boilers operate like a tea kettle. As water heats to a boil it builds pressure as it reaches the state of steam. Unlike hot water boilers which rely upon a pump to circulate the hot water, steam boilers use this pressure to move the steam through the piping system. The piping system of a steam boiler is usually a one-pipe or two-pipe system.
If a high degree of construction cleanliness is maintained, a water flush of condensate and feedwater systems may be used, along with an alkaline boil-out followed by a steam blow of the steam generator. This can provide sufficient cleaning in most boilers that operate at less than 900 psig.

A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam locomotives,
