Abstract :
Mathematical model for heat-impulse-mass transfer in vessel is proposed. Theory of similarity is applied to transfer in vessel. Kinetic coefficient of stone growth have no significant dependence on geometry of growth zone but depends on solution physical properties and temperature difference between neighbor stone´s faces. The phenomena of seed location influence on quartz growth rate are discussed. Optimum location of baffle plate in respect to isotherms is estimated
