FIELD: gas supply.
SUBSTANCE: method consists of IR source and reflector. Heat flow from reflector is determined as difference between heater heat flow and IR source heat flow for IR source with radiation wave length from 0.5 to 7mcm at constant suspension height. Maximum heat flow from reflector is defined. Dependence of maximum reflector heat flow at angle deviation from normal line to the exposed surface and reflector edge height is also calculated. Optimal angle corresponding to maximum heat flow is defined. Height of reflector edges is increased at optimal angle to the sizes when temperature at low reflector edge is equal to ambient temperature. Heat flow density on the exposed surface is reduced by changing angle between normal line to exposed surface and reflector edge plane from 0° to optimal α=αopt angle value or from α=αopt to 90°.
EFFECT: change of heat flow density from IR source.
