Crematory High Emissivity Coating: 21% Energy Savings with Cremkote
| Industry | Crematories |
|---|---|
| Asset | Cremation unit, main and afterburner chambers |
| Customer or location | Cremation facility |
| Products used | Cremkote® |
| Headline metric | 21% energy savings |
| Secondary metric | Faster cycle times |
| Also measured | ROI under one year |
| Also measured | 1,850°F (1,010°C), natural gas |
A cremation facility applied Cremkote to the crown and walls of the main chamber and the walls of the afterburner chamber of its natural-gas cremation units, on refractory brick with the hearth left uncoated. Energy use fell 21%, cycle times shortened, and the project returned its cost in under a year.
01
What was the challenge?
Gas cost per cremation and cycle time on units operating at 1,850°F.
02
What was applied?
Cremkote on the main chamber crown and walls and the afterburner chamber walls; substrate firebrick and refractory brick; hearth not coated.
03
What were the results?
| Metric | Before | After |
|---|---|---|
| Energy consumption | Baseline | −21% |
| Cycle time | Baseline | Faster |
| Return on investment | Less than one year |
04
Why did it work?
Coated chamber surfaces absorb burner energy and re-radiate it uniformly into the chamber instead of losing it to the flue, so the unit reaches and holds temperature on less gas and completes each cycle sooner. See Crematories.
