Pain Points of Traditional Oxidation Blowers in FGD Desulfurization System

Traditional Roots blowers and ordinary centrifugal blowers are widely used in limestone‑gypsum wet flue gas desulfurization oxidation air supply, but bring obvious drawbacks for power‑plant operators:

  1. High energy consumption: large power waste under variable‑oxygen‑demand working conditions
  2. Heavy vibration & mechanical wear: frequent spare‑part replacement, high operation‑maintenance cost
  3. Lubricating‑oil leakage risk: oil contamination may affect gypsum quality and desulfurization efficiency
  4. Unstable air pressure: uneven oxidation of calcium sulfite, poor flue‑gas treatment effect
  5. High noise level, poor on‑site working environment

These long‑term pain points push energy‑intensive enterprises to upgrade toward magnetic‑levitation oxidation blowers for energy‑saving technical transformation.

Product Performance Advantages of Magnetic Levitation Oxidation Blower

1. Outstanding Energy‑saving Benefit

The magnetic levitation oxidation blower eliminates friction loss of mechanical bearings and gearboxes. Under real‑site test of the 300 kW completed project, the comprehensive energy‑saving rate reaches 20‑30%. Calculated on 8000 running hours per year, single unit can save more than 900 000 kWh electricity, greatly cutting enterprise power‑expense and supporting carbon‑reduction targets.

2. Low‑noise Stable Operation & Minimal Maintenance

Running noise ≤ 80 dB(A), which is around 20 dB(A) lower than traditional blowers, greatly improves workshop working environment.

Zero‑oil full‑life operation removes lubrication‑oil system completely. Daily maintenance only needs to replace air filter cotton periodically. Maintenance cost is reduced by over 60 %, failure rate drops by 80 %. It avoids unexpected plant shutdown caused by blower breakdown.

3. Intelligent Digital Safe Operation

Embedded digital monitoring platform tracks real‑time temperature, airflow, air pressure, rotor vibration and other core parameters. It supports fault early warning and remote operation. The blower can seamlessly connect with power‑plant DCS control system, realizing smart unmanned‑operation management, to guarantee long‑term stable FGD‑system emission compliance.
