Oxygen enhances the combustion of all fuels enabling improved burning zone control greater kiln stability and lower emissions By increasing the oxygen concentration of combustion air through the addition of relatively pure oxygen flame temperatures rise heat transfer rates improve and overall combustion efficiency increases
read the restUpdraft kilns are those in which the flame is introduced into the bottom of the kiln at or below floor level and exhausted out the top Although an updraft kiln tends to be less fuel efficient than a downdraft kiln most commercially built fuelburning kilns are updrafts This is mainly due to their simplicity to build pack and ship 02
read the restThe heat created from this burning produces steam which is then used to turn a generator to produce electricity But coal also has many other uses In manufacturing processes it is used as a source of heat Bricks and cement are made in kiln ovens heated by the combustion of a jet of powdered coal
read the restToday nearly all new kilns installed have precalciners They represent the final improvement in efficiency and hold out the prospect for nearly total elimination of heat wastage from cement kilns The precalciner system is a suspension preheater in which in addition to the kiln flame extra fuel is burned in the base of the preheater The
