INFRARED HEATER AND COMPONENTS THEREOF

摘要

A new infrared heater (10) containing a gas fired burner having a metallic burner body (12) with a combustion plenum chamber (20), a matrix (30) which covers the combustion mixture plenum and a screen (42) made of fibers treated with a silicon carbide and/or oxycarbide. The screen (42) could be connected to the matrix (30) by a pressure fit. The invention also relates to a new matrix (30) that is energy efficient and made from fibers ceramic or metallic, treated with a pre-ceramic polymer containing (a) silicon and carbon and/or (b) oxycarbide to rigidize the matrix (30) and increase its emittance. The matrix (30) could also have a variety of surfaces that are also more efficient.
