Energy saving transformation of fly ash reuse
Background of Technical Renovation: The original 3 # dust removal and return system was powered by a 18.5KW Roots blower to transport fly ash to the boiler. In order to save energy consumption, the original 3 motors were temporarily stopped (standby) and replaced with axial flow compressors for compressed air blowing, effectively improving the efficiency of ash return and reducing the use of energy and electricity.
The discontinuation of the original fan greatly saved electricity consumption and daily maintenance costs, saving about 222 kWh per unit and shift, and saving an annual electricity fee of 101232 yuan, which saved costs for the workshop. After experimental verification, it has been proven that the effect is significant. The blowing device of the fly ash re ignition system for boilers 1 and 2 has also been upgraded and transformed to compressed air assisted blowing, reducing power consumption and lowering production costs.
