Insulation solves conduction. But in equipment running above 900 °C, conduction isn't the dominant mechanism. Radiation is.
And radiation is governed by a parameter almost nobody measures: the emissivity of the working layer.
Conventional ceramic fibre sits at ε = 0.2–0.3. In practice, that means the lining reflects most of the incident radiation, the combustion gases absorb that energy, and it leaves through the stack.
With a 𝑅𝐴𝐺 𝑇𝑒𝑐ℎ® ℎ𝑖𝑔ℎ-𝑒𝑚𝑖𝑠𝑠𝑖𝑣𝑖𝑡𝑦 𝑐𝑜𝑎𝑡𝑖𝑛𝑔, the surface moves to ε = 0.85–0.95. The wall stops reflecting and starts re-emitting back into the process.
The numbers behind it:
→ 50 µm average thickness. No penalty to chamber volume.
→ Service temperature up to 1700 °C, thermal shock validated from -200 °C to 1500 °C.
→ Less ceramic fibre devitrification and fewer contraction-expansion cycles: the lining lasts longer.
→ Better combustion → lower NOx, CO and CO₂.
𝑊ℎ𝑒𝑟𝑒 𝑤𝑒 𝑖𝑛𝑠𝑡𝑎𝑙𝑙 𝑖𝑡 𝑚𝑜𝑠𝑡:
Reheat and heat treatment furnaces — walking beam, batch and continuous
Tunnel and intermittent kilns — ceramics, brick, refractories
Fired heaters and process furnaces — hydrocarbon and chemical
Glass melting furnaces, ports and regenerators
Biomass boilers, waste incinerators and gas-fired boilers
Burner components — tips, swirlers, radiant tubes and pre-coated OEM parts
One honest caveat: not every asset is a candidate. That's why the process always starts with an inspection of the existing lining and a technical questionnaire on operating conditions — not with a quote.
Because at PROYCO we don't sell a bucket of coating. We engineer the complete lining — working layer, insulating layer and emissive layer — and we specify the solution around your process, not around a manufacturer's catalogue.
