INCREASING ENERGETICAL EFFICIENCY OF HEAT-TECHNOLOGICAL PLANTS ON BASE OF DEVELOPING AND OPTIMIZING REGENERATIVE HEAT EXCHANGERS

The work covers the heat exchangers for regenerative heat use of the waste gases from heat-technological plants. The aim is to increase the energetical efficiency of heat-technological plants on base of renegerating waste gas heat. The mathematical descriptions of the conjugated heat exchange in the recuperators at presence of the transients and heat- and mass exchange in the contact heat exchanger at presence of the film draining of over channel walls have been drawn up. The new designs have been developed, and the mathematical models of heat exchangers have been drawn up. The heat exchangers have been introduced in the enterprises, the mathematical models have been used at designing.
