Reasons for corrosion in Luchie furnaces
Thread Content
In large-scale coal-to-gas production, Lurgi boilers are currently used for processing soybeans. Among the plants in operation today, corrosion of these boilers has become a problem. What do you think are the root causes of this issue?
1. The proportion of various elements in different coal types； 2. Cladding alloy is considered for the inner wall of the gasifier.
For furnaces that have already been built, carrying out such treatment is not only time-consuming but also costly. Impatience is a common problem among domestic enterprises, and due to this issue, lining the inner walls with weldments is not considered. For newly built furnaces, lining the inner wall with weldments is also one option to consider. However, doing so increases the cost of the gasification furnace significantly; in an environment where funding is limited, how many companies can afford such expenses?
This requires thorough preparation in advance to avoid the embarrassment of having to seek medical attention when sick; it’s always good to exercise regularly
