Abstract
A new infrared heater containing a gas fired burner having a metallic burner body with a combustion plenum chamber, a matrix which covers the combustion mixture plenum and a screen made of fibers treated with a silicon carbide. The screen could be connected to the matrix by a pressure fit. The invention also relates to a new matrix that is energy efficient and made from fibers ceramic or metallic, treated with a pre-ceramic polymer containing silicon and carbon to rigidize the matrix and increase its emittance. The matrix could also have a variety of surfaces that are also more efficient.
Claims18
In an infrared heater containing a gas fired burner having a metallic burner body with a combustion plenum chamber, and a matrix covering the combustion plenum chamber wherein the improvement comprises said matrix comprising a matrix body made of fibers treated with a pre-ceramic polymer containing silicon and carbon.
A matrix for use in a radiant gas burner which comprises a matrix body made of fibers treated with a pre-ceramic polymer containing silicon and carbon and said matrix is used in a radiant gas burner and said matrix body has at least one exposed convoluted surface shape that is corrugated and having angles in the corrugate from about 60 to about 120°.
A matrix for use in a radiant gas burner which comprises a matrix body made of fibers treated with a pre-ceramic polymer containing silicon and carbon and said matrix is used in a radiant gas burner wherein the surface of the matrix is double convoluted having ridges and valleys wherein said ridges are in said valleys.
In gas infrared burner having a metallic body with a combustion plenum having a chamber and a matrix which covers the combustion mixture plenum chamber, wherein the improvement comprises a screen connected to the plenum by a press fit without additional structure being required to secure the screen into place.
A radiant gas burner matrix which comprises a matrix body made of fibers treated with a pre-ceramic polymer containing silicon and carbon and said matrix body permits a gaseous combustion mixture to pass through said matrix body and as said mixture emerges, said mixture is burned to heat emerging surface to incandescene.
