DEVICE FOR DECREASE OF THERMAL ENERGY DISSIPATION TO ENVIRONMENT

摘要

The invention relates to burners, in particular to means for concentration of thermal energy. A device for decrease of dissipation of energy of burner has a surface for heating and a screen as diffuser installed coaxially with burner. Widened part of diffuser is directed towards surface for heating. Inner surface of the screen is made reflecting. Openings for passage of air are arranged in the narrow part of diffuser with uniform spacing and have gates. The screen can be equipped with base for placement on surface of plate round the burner. The invention promotes more quick heating of surface and decrease of gas flow rate.
