The second major water-related boiler problem is corrosion, the most common example being the attack of steel by oxygen. This occurs in water supply systems, preboiler systems, boilers, condensate return lines, and in virtually any portion of the steam cycle where oxygen is present. Oxygen attack is accelerated by high temperature and by low pH.Get Price

The hot fire in a boiler is a reaction between natural gas and oxygen — the units burn methane (CH4) or propane (C3H8) and oxygen (O2) to produce H20 (water) and CO2 (carbon dioxide). But the hot flame also sucks in atmospheric nitrogen, which makes up 70% of the atmosphere, and the fire is hot enough to force the nitrogen to react with oxygen.Get Price
Causes, and prevention of corrosion in boilers, type of corrosion. Corrosion is the reversion of a metal to its ore form. Iron, for example, reverts to iron oxide as the result of corrosion. The process of corrosion, however is a complex electro chemical reaction and it takes many forms.Get Price

Blowdown in Boiler Definition. Blowdown in Boiler, Usually, water which is fed to the boiler contains high Total Dissolved Solids (TDS) content as well as other dissolved and undissolved solids in it. On heating water or converting water to steam, these dissolved solids do not evaporate and gets separated from water or steam and settled at the bottom of the shell.Get Price
