Advantages and disadvantages of adding fans to sulfur recovery exhaust gas
Thread Content
Dear sea friends, the sulfur recovery unit is set to have an exhaust fan added after the incinerator; the pressurized exhaust gas will then be sent to the boiler. What are the risks associated with this exhaust fan, and what precautions should be taken in the future?
What medium does the fan transport – oxygen, flammable materials, or something else? And what is it used for in the boiler?
It is essential to thoroughly demonstrate the impact of abnormal shutdown of the booster fan on production
See if it’s necessary to increase or not
If it’s burned in the exhaust, then emissions will be produced – what’s the point of sending it to the boiler?
Due to current environmental regulations, it must be sent to the boiler for desulfurization and denitration.
Temperature: 750° SO2: 0.041% CO2: 19.1% H2O: 15.8% O2: 9% N2: 55.30% Sent to boiler for desulfurization and denitration
What needs to be added? Any good suggestions?
To add fans, it is necessary to discuss this with the boiler technicians, inform them of the gas composition, and jointly analyze the impact of that composition on desulfurization and denitrification
As mentioned in the previous sections, what needs attention now is the subsequent maintenance of the fans, as corrosion is quite severe. I’m wondering if anyone has any good suggestions.
Well, in the sulfur recovery project I’m working on, the exhaust gas after passing through the incinerator enters a steam generator to recover heat, which is then used for desulfurization and denitrification; no booster fans are used. . . .
