Experimental study and mechanism analysis on low

Dec 31, 2020 · When the flue gas temperature falls below the dew point (temperature below which condensation of moisture takes place). Which leads to a severe corrosion problem at the cold end of the boilers. ie., air pre-heater installed just before the flue gas exit to the stack or induced draft fans. Prevention Methods

Water Handbook - Preboiler & Industrial Boiler Corrosion

Aug 21, 2009 · In order to avoid or reduce the cold end corrosion the gas temperature leaving the heat transfer surface in boiler is kept around 150 degrees centigrade, ranging from 120 to 155. It is very important that the metal temperature of the tubes is always kept above the condensation temperature.

Boiler Cold End corrosion - Mechanism and prevention methods

Liming 17:46:57. The sulfuric acid corrosion of the heating surface (economizer and air preheater) is caused by flue gas and the lower tube wall temperature at the tail heating surface, so which is called low temperature corrosion. The sulfur in the fuel burns to produce sulfur dioxide, and sulfur dioxide is further oxidized to produce three sulfur oxides under the action of the catalyst, and steam of sulfuric acid is

What is the difference between a conventional, low

Unfortunately, you cannot directly monitor the pH inside the heat of the boiler. Rather, you must measure pH from a cooler, lower-pressure side stream. Monitoring the water and steam for sodium will also help you prevent corrosion by finding out if you need to control for the mineral presence in the system.

Caustic Corrosion - an overview | ScienceDirect Topics

The solution. Protecting a central heating system and all of its component metals against these kinds of corrosion is as simple as follows: Ensure careful and correct installation and commissioning (or maintenance) of the system to minimise issues of contamination such as flux residues or existing corrosion deposits.
