Oxyfuel combustion

Replacing combustion air (79% nitrogen ballast) with oxygen cuts flue-gas volume ~75%, raising efficiency and concentrating CO2 for future capture.

How it works

Mechanism & sizing

Standard in glass; growing in metals reheating. Economics = fuel saved vs oxygen cost — favourable where furnace efficiency is poor or oxygen is on-site. The concentrated CO2 stream halves future capture cost: oxyfuel is the CCS on-ramp.

Inzonex removable modular insulation on industrial equipment
Cut the tonnes at the source

Hot industrial equipment? Cut the heat loss.

Boilers, kilns, heat exchangers, valves and steam lines lose energy continuously. Inzonex makes patented (UK GB2508992.1) removable modular insulation — snap-fastened covers engineered per temperature tier, not generic off-the-shelf jackets:

  • Up to 90% less heat loss from insulated surfaces
  • Surface temperature ≤45 °C — touch-safe for workers (EN ISO 13732-1)
  • 6× faster maintenance access than fixed cut-and-weld lagging — unclips and refits in minutes, no destruction
  • Inspectable — comes off to check for corrosion under insulation, then refits like-new (generic jackets often don't survive removal)
  • Typical payback under 2 years (some 9–11 months)

FAQ

Oxyfuel combustion, answered

Why does oxygen save fuel?
No nitrogen to heat and exhaust: flue losses drop with flue volume — 10–25% fuel on typical furnace retrofits.
What's the CCS link?
Oxyfuel flue gas is mostly CO2 + H2O — dehydration yields capture-ready CO2 at a fraction of post-combustion cost.
Where is it proven?
Container and fibre glass widely; reheating furnaces and aluminium melters increasingly.
