Severe ash accumulation is present behind the induced draft fan in the flue of the atmospheric and vacuum distillation heating furnace
Thread Content
Today I visited a vacuum distillation unit that was under maintenance; the fuel for its heating furnace is ethylene tar. The duct behind the exhaust fan had been opened, and I saw black ash mixed with white and yellow substances, with in some areas these three elements (black ash, white substances, yellow substances) having condensed into very hard lumps. How was it formed? And how can it be prevented? I would be very grateful if the expert could provide an explanation. Thank you!
It’s the same – the impurities that are produced after combustion cannot be prevented when using oil, nor is it necessary to try to prevent them. Due to environmental concerns, burners that use oil will soon be converted to those that use gas, and fuel burners will hardly be seen in the future
Is it exported to the low-temperature anti-corrosion heat exchanger? The temperature is low after the replacement, and this kind of thing may occur
