Crematory Furnace Efficiency
Crematory systems operate under repeated thermal cycling. Each cycle introduces heat-up delays, uneven temperature distribution, and ongoing stress on refractory surfaces. Over time, this leads to longer cremation cycles, higher fuel usage, and inconsistent performance inside the crematory furnace.
Improving output is not typically limited by burner capacity. It is driven by how effectively heat is absorbed and distributed within the chamber.
Cremkote, a high emissivity coating developed by Emisshield, is designed to improve how heat moves inside the crematory furnace without requiring changes to the system itself.
Where Performance Is Lost Inside the Crematory Furnace
During operation, radiant energy from burners and hot gases is not fully utilized. Portions of that energy are reflected or unevenly distributed, creating localized hot and cold zones within the chamber.
This leads to:
- Longer time to reach operating temperature
- Inconsistent burn conditions
- Increased fuel demand to maintain setpoints
These inefficiencies compound across every cycle.
How Cremkote Changes Heat Behavior
When applied to the hot face of refractory surfaces, Cremkote increases the amount of radiant energy absorbed at the surface. That energy is then re-radiated more evenly throughout the chamber.
Instead of heat concentrating in specific areas, the crematory furnace operates with a more balanced temperature profile.
This shift in heat behavior leads to:
- Faster heat-up times
- More consistent internal temperatures
- Reduced reliance on excess fuel to maintain performance
Operational Impact Over Time
As temperature distribution becomes more uniform, the effects show up in daily operation:
- Shorter cremation cycles, often reduced by 20–30%
- Lower fuel consumption across each burn
- Faster cool-down between cycles
- Increased daily throughput without added strain on the system
At the same time, more even heat reduces thermal stress on refractory materials, helping extend service life inside the crematory furnace.
Application Within Existing Systems
Cremkote is applied directly to refractory or metal surfaces during scheduled maintenance. The process is straightforward and does not require major system changes or extended downtime.
Once applied, the coating begins influencing heat transfer immediately, improving performance from the first operational cycle.
