AI Technical Summary
Existing biomass boiler economizers suffer from slow spray cooling and corrosion problems due to poor solubility of dilute hydrochloric acid and dilute sulfuric acid, resulting in a shortened service life of the equipment.
The system combines high-temperature and low-temperature control components. The high-temperature section uses a closed-loop condensation heat exchanger, while the low-temperature section dissipates heat through air. The reciprocating screw of the heat dissipation component drives the cooling fan and the serpentine pipe layout to achieve targeted and localized enhanced heat dissipation and avoid the formation of dilute acid.
It effectively avoids dilute acid corrosion, extends the service life of the equipment, and improves the efficiency and stability of flue gas temperature regulation.
