Specialized coal and pet-coke firing pipe design

Abstract

This paper discusses specialized coal and pet-coke-firing, viewing the design of customized combustion systems in order to meet client's specific requirements. This is an approach to combustion subject that is becoming well known and widely accepted all over the world, fitting particularly well when the combustion takes place inside a clinker rotary kiln. The best way to perform this approach is by means of dimensionless indexes, which characterize macroscopically the result of a wide variety of simultaneous chemical reactions, and phenomena of heat, mass and momentum transfer. The most significant dimensionless indexes, which help tremendously in the combustion system design, are presented and discussed.
