Structural issues of the waste heat boiler tubes in the semi-dry acid production process
Thread Content
Gentlemen: Are there any good solutions to the problem of scale formation on the tubes of semi-dry exhaust heat boilers? The furnace tube is 9.5 meters long, and using mechanical descaling methods is currently time-consuming and labor-intensive.
Chemical cleaning methods can be tried to address the problem of scale buildup in furnace tubes. The specific method is as follows: 1. Add a cleaning agent to the boiler, such as an acidic or alkaline cleaning agent, using the proportions specified in the agent’s instructions. 2. Heat the boiler to allow the cleaning agent to circulate within it; this agent can dissolve and remove the scale buildup inside the furnace tubes. 3. After cleaning is complete, thoroughly clean the interior of the boiler and completely drain the water containing the cleaning agent to prevent environmental pollution. Additionally, it is possible to consider installing anti-scaling equipment and using scale prevention agents regularly to reduce the occurrence of scaling in the furnace tubes. .
It is recommended to try using a vertical water-tube boiler, with water flowing inside the tubes and flue gas flowing between them
