MASSIVE, VOLUMETRIC AND ENERGETIC EFFECTS OF COAL EXCHANGE BETWEEN COKE AND EXHAUST GASES AT VARIOUS LEVELS OF CUPOLA PROCESSING STACK

Formulas for the calculation of mass, volume and energetic effects bound with reaction CO(2) + C = 2 CO have been derived in the paper. The effects occur in the charge coke, which pass from the upper boundary of the heating zone to the lower boundary of the combustion zone as well as in the cupola gases generated in the combustion area and moving through the charge material stack to the upper boundary of the heating region. The formulas include the effects at the lower levels and the maximum effects i.e. occurring between the lower boundary of the combustion zone and the upper melting region. The presented example of calculations contains full information on the size of analyzed reaction effects and describes its energetic model. The work contributes to the elaboration of so far inexisting theory of thermal zone and subzone balances of cupolas as well as the method of calculation of gas temperature at the sub- and zone boundaries followed by the kinetics of zone processes, which depend on the temperature of gases
