|---|---|---|
| System change | Increase oxygen concentration in the oxidant to reduce nitrogen ballast in suitable combustion systems. | Replace or supplement fuel-fired heat using electric resistance, induction, electric boilers or other electric technologies. |
| Evidence required | Furnace duty, fuel, oxygen supply, exhaust composition, heat transfer, product quality, emissions and burner design. | Duty and temperature profile, connection capacity, tariff, load flexibility, equipment efficiency, electricity factor and backup requirement. |
| Principal constraint | Oxygen cost, flame conditions, materials and emissions must be assessed by the combustion-system designer. | The result depends on the electrical system and reporting boundary; it is not automatically lower-cost or lower-carbon. |

Use measured surface area, temperature and operating hours to calculate heat loss from boilers, kilns, heat exchangers, valves and pipework. Inzonex supplies removable modular insulation for equipment that requires maintenance access.
Do not add a calculated reduction to an emissions report until the reporting boundary, factor, implementation date and verification method have been approved.
