When do I repair my (human) crematory
- Hearth repairs are typically needed between 2000 and 2500 cremations depending how heavily used. The hearth will begin to wear and create a depression directly under the cremation burner. At this point it will rapidly deteriorate, become weak and a hole will develop in your hearth. Capping a hearth is not recommended as it only temporarily covers an area that could collapse and create further problems.
- Repairs ar needed when the brick on both sides of the loading door and overhead roof lentil are broken away or missing. Missing refractory around the loading and clean out doors will let to much air leak in and the heat and flame feeds off the leaking air. These areas become very hot and create to much heat stress to the metal face plate and will burn away and develop warped steel. Warped steel can cause door closer issues, sticking or not closing all the way.
- The after burner roof (in most models) can and will break away around the burner opening. This will cause the burner flame to speed to wide and direct flame impingement on the surrounding brick walls will occur. This will cause the brick to get to hot and glass over becoming very brittle and brick spalling occurs. This are should be replaced soon as the heart can reach the exterior roof metal causing additional damage.
- Your crematory should be inspected regularly by a qualified technician to avoid costly damage. Yearly tune ups and inspections will keep your retort running safely and properly. A qualified technician will advise you of any areas of concern and will recommend a solution to correct it.
- Crematory repairs and service can get very expensive. Regular maintenance and inspections will keep your unit running better longer.
