Environmental Protection Industry - Exhaust Gas Treatment System Regeneration Fan

Regenerative fans are mainly used for exhaust gas treatment, energy recovery and process optimisation.
Core Functions
1. Flue gas recirculation
Reintroducing some of the low-temperature flue gas into the combustion system lowers the combustion temperature, suppressing the formation of nitrogen oxides (NOx) while also improving fuel efficiency. This technology can reduce NOx emissions by 30%-50% and reduce fuel consumption by 5%-10%.

2. Catalyst regeneration assistance
In processes such as catalytic cracking, fluidising air or oxidising air is provided to the regenerator to burn off coke on the catalyst surface to restore activity and provide heat energy for the reaction. For example, the catalytic cracking regenerator must maintain a high temperature environment of 650-750°C.

2. Typical Application Scenarios
2. Environmental protection and emission reduction
Power plants and steel mills use flue gas recirculation technology to meet environmental regulations. A typical case shows that the annual electricity consumption of a chemical plant decreased by 20%.

3. Petrochemical industry
In catalytic cracking units, the high-temperature air (>600°C) from the regeneration blower can process sulfur-containing flue gas and requires a design with corrosion-resistant materials.

4. Energy recovery

In a circulating fluidised bed boiler, the regeneration fan works in conjunction with the primary/secondary fans to achieve staged fuel combustion and waste heat utilisation.

Q: How can I keep up with the product progress if I don't go to your company?

After placing an order, we will report the production progress regularly

Q: What information do I need to provide to get an accurate quotation?

The operating conditions for the gas to be delivered include flow rate (m3/h), total pressure (Pa), temperature (℃), gas density (kg/m3), and the altitude of the usage location (m); the material of the fan; the voltage, frequency, protection level, explosion-proof level, and whether the motor is variable frequency or not.

Q: Can your packaging ensure the safety of the product?

We wrap the inlet and outlet of the fan, as well as the motor, with stretch film and then secure the fan in a wooden box, which can fully protect the product during transportation and handling.
