The paper deals with new melting technology of chemical agents with antireflection liquid phase by means of light radiation. A method of melting is proposed, based on the light radiation effect. Emitter design based on halogen lamps is developed and used as a nozzle to the contact heater. The lamps are placed into individual transparent cases which gives the possibility to align the temperature distribution on the emitter surface and avoid excessive heat of the lamps. Such emitters were used for melting of synthetic fatty acids used in the production of detergents. Previously developed calculating methods for the melting process velocity of the combined influence of light radiation and thermal power released on the surface of the transparent case on the melting agents are used in the process of emitter designing. The number of emitters and the distance between them are determined in view of calculations and data of light and thermal characteristics of emitters. Experimental verification showed the possibility of channel depth melting equal to 1 m in 5-6 hours. This is three times less than it is necessary for channel melting by contact heater. At the same time energy consumption is increased only by 7 % as compared with that one of the contact heater. Furthermore, the channel melted down has got a diameter larger than by using only a contact heater.
