Use this record when

The decision this case can inform

Higher alternative-fuel use requires flexible backup fuel delivery and controls.

Evidence scope

Supplier-reported evidence. Results apply only to the stated equipment, conditions and observation period.

Source-supported facts

What the public record actually establishes

2 sourced points
  1. F1

    A package of fuel-system upgrades included Feedflex commissioning.

  2. F2

    The supplier reports more than 1 t/hour additional coal displacement from optimized SRF feeders and the Feedflex upgrade, beyond the pyrolyzer alone.

Structured interpretation

Facts and reported results are kept separate from the lesson a plant may choose to test.

Operating context

Higher alternative-fuel use required changes to fuel feeding and calciner operation.

02

Intervention or finding

A package of fuel-system upgrades included Feedflex commissioning.

03

Documented result

The supplier reports more than 1 t/hour additional coal displacement from optimized SRF feeders and the Feedflex upgrade, beyond the pyrolyzer alone.

04

Plant interpretation

Higher alternative-fuel use requires flexible backup fuel delivery and controls.

05

Transfer boundary

Bundled upgrades complicate attribution. This is an operating-rate claim, not a verified annual CO2 total.

Before applying the lesson

Questions to verify at your plant

These are decision checks, not operating instructions. Resolve them through local risk assessment, technical review, and authorization.

  1. 01

    Match fuel heating values and operating hours; retain fallback-fuel and blockage behavior in the case.

  2. 02

    What equipment, materials and operating conditions differ at your plant?

  3. 03

    What baseline and follow-up evidence would establish whether this change works locally?
