Consulting Services - Power Generation

Reducing O&M Costs and Improving Unit Availability

  • Gas-Side Flow Patterns - Measurement and Visualization
  • Flow Modification - Systematic Redistribution of Gas and Gas-borne Ash (particulate) to uniform Levels.
  • Reduce Pressure Part Failures due to Fly Ash (Particulate) Impact Erosion
  • Reduce O&M Costs and Improve Unit Availability

Since 1998 DE has provided engineering services to measure, visualize and modify boiler gas-side flow and fly ash (particulate) distributions. Flow adjustments can prevent pressure part and structural support failures and increase process efficiency.
