zone ( 44 K). This results in a deterioration of the heat transfer from the gas to the kiln feed, and the gas temperature at the kiln inlet rises by 10 K. Increased recirculating dust systems lead to the establishment of higher temperatures than in the reference condition, especially in the upper part of the preheater.

Heat balances are used in engineering for the analysis of thermal processes occurring in, for example, steam boilers, furnaces, and heat engines. A heat balance may be expressed in units of energy, such as joules or calories, or in percent of the total amount of heat per unit output, per hour of operation, per time period (cycle), or per kilogram of material used.

Sidefired kilns are used to anneal tall pieces or to slump or fuse on multiple layers within the kiln. Zone Control allows each section of the kiln to fire independently of the other. Therefore, if the kiln is firing unevenly, sections can turn on or off to balance the heat. These kilns also have balanced elements.

Kiln Wikipedia

A kiln is a thermally insulated chamber, a type of oven, that produces temperatures sufficient to complete some process, such as hardening, drying, or chemical changes. Kilns have been used for millennia to turn objects made from clay into pottery, tiles and bricks. Various industries use rotary kilns for pyroprocessing—to calcinate ores, to calcinate limestone to lime for cement, and to transform many .

These two zones serve to increase the temperature of the pellets prior to the kiln, and here the main part of the oxidation to hematite takes place [9]. Oxidation of the pellets releases a large amount of heat – this is the main heat source in the process[5]. The heated pellet bed then enters the rotary kiln, shown schematically in Figure
