The hotter flue gas then deposits material in the next section of the boiler, which is usually the generator bank. Since this area is more closely spaced on the assumption that it will never receive these deposits, it lodges solidly with ash, such that sootblowers cannot remove the deposits effectively.

Water Handbook -Boiler Deposits: Occurrence And Control | SUEZ

The nature of the scale formed depends on the chemical composition of the concentrated water. Normal deposit constituents are calcium, magnesium, silica, aluminum, iron, and (in some cases) sodium. The exact combinations in which they exist vary from boiler to boiler, and from location to location within a boiler (Table 12-1).

Boiler feed water - Lenntech

Proper treatment of boiler feed water is an important part of operating and maintaining a boiler system. As steam is produced, dissolved solids become concentrated and form deposits inside the boiler. This leads to poor heat transfer and reduces the efficiency of the

Experimental Investigation of Ash Deposit Shedding in a Straw …

Straw is used as fuel in grate boilers in Denmark to produce heat and electricity. One of the technical problems in these biomass boilers is the formation of an alkali-rich ash deposit, which may seriously affect heat transfer to the plant steam cycle and cause degradation of steam tubes by corrosion. While the processes of boiler ash deposit formation for both coal and biomass have been the
