B&L Cremation Systems, Inc. | Burners And Relays FAQ

1. What is the average cubic feet of gas consumed during the average cremation, and do all models have the same burner placement?

The average fuel consumption of our systems is 700 to 1000 cubic feet per hour.  This, of course, is dependent on the amount of cremations being processed and the average air temperature.  All of our models have top-fired burners.

2. What is the difference between burner placement pros and cons?

Most modern retorts have overhead burners.  This feature prevents fluids and debris from entering the burner port, while eliminating the need for a steel plate being placed over the burner during the retrieval of the remains.  The only disadvantage of the overhead system is flame erosion of the hearth due to flame impingement.  To help combat this problem, we fire our cremation burner at a 15 degree angle so the flame does not make direct contact with the hearth.

3. Can the burners be replaced?

Yes, however the style of cremation burners we use in our system have no moving parts, and therefore, do not need to be replaced.
