This paper, by Klaus S. Feindler, is a good contribution to the understanding of two-stage municipal combustors. He has mixed and quartered the ash from the one-half inch by one-half inch under stream in accordance with ASTM-D346-78. It is suggested that this mixing and quartering procedure be used earlier in the field processing procedure. Also, with a high level of consistently good annual performance, why was there such a concern with the month-to-month SAR? There is hardly any mention of the fact that continuously-fired, two-stage combustors produce a heavy loading of fixed carbon in the furnace residue and a high unburned combustible loss. Rather, the paper draws a number of conclusions from a small amount of test data. In addition, some of the data appear to have been incorrectly interpreted. Additional information is requested on the following: mass balancing of the facility; ash sampling; correlation of operational data to lab data; ash model/solid waste model calibration/validation; and improvement/Test I data. This article also contains the original author`s reply to the comments and questions.
