High Emissivity Coatings for Fired Heater and Process Furnace Applications
Emisshield and its Strategic Partners have years of experience improving fired heater and process furnace performance in hydrocarbon and chemical operations. With this experience, we analyze specific unit conditions, provide solution-based high emissivity coating technologies, and apply them with professional precision.
Our high emissivity refractory and metal coatings for fired heaters and process furnaces in the hydrocarbon and chemical industry reduce downtime, minimize coking, increase productivity, and lower overall carbon footprint by improving radiant heat transfer and promoting uniform temperature distribution. These qualities are critical to maintaining fired heater efficiency and overall refinery furnace performance.
Emisshield coatings are engineered to strongly adhere to refractories and metals at high operational temperatures commonly found in fired heaters and high-temperature process furnaces.
Applications:
Emisshield high emissivity coatings are engineered for high-temperature fired heater and process furnace environments, including:
- Fired Heaters
- Primary and Secondary Reformers
- Cracker Furnaces
- Sulfur Recovery Units (SRU)
- Waste Incinerators
- Thermal Oxidation Units
- Burners
- Flares
Emisshield products can be applied in the field during operational shutdowns on existing fired heaters, process furnaces, refractories, and metal surfaces. Our partners’ ability to retrofit these high-temperature furnace systems makes the technology ideal for plants seeking to minimize shutdown duration while maximizing operational efficiency.

High temperature fired heaters and process furnaces are used in a wide range of hydrocarbon and chemical processing operations. A key factor in fired heater efficiency and process throughput is efficient radiant heat transfer from flames to the process material or process tubes.
For gas-fired furnaces, conventional furnace refractories tend to reflect a majority of arriving radiant energy back into the furnace flue gas at the same spectral wavelength at which it is emitted. This energy is then absorbed again by the flue gas, limiting the amount of energy transferred to the process tubes or materials.
Emisshield coatings on furnace walls absorb more of the incident radiant energy and reemit this energy across the wavelength spectrum, including emission through transparent windows in the spectrum. This spectral redistribution of emitted energy allows more radiant energy to pass through the flue gas and be transferred to the process surface.
Introducing our sustainability-focused products for fired heater and refinery furnace applications is one way we continue advancing high emissivity coating technology. These solutions focus on reducing carbon emissions and supporting refinery efficiency without major capital upgrades.
