An experimental study on metal fibre burner used for gas water heater and gas kitchen range for Chinese food is carried out,and the relationship between harmful substances(CO and NO_x) emissions from two kinds of metal fibre burners and factors,including thermal intensity of burner port,air coefficient,distance of metal fibre surface from surface heated(height from pot bottom) etc.

The characteristics and working principle of metal fibre burner are introduced.

The research scheme on pressure loss performance of metal fibre burner was put fouward, and experimental installation was set up.

Category and component of porous media for combustion of metal fiber burner,as well as fundamental construction and properties of the metal fiber burner were introduced.

As a newly born surface-combustion radiant gas burner, the metal fiber burner has gained great attention and will be widely used because of its good properties.

The bubble pore size and diameter distributing of rigid porous filter media are studied in the paper,such as metal silk screen,metal fiber sintered felt,ceramic membrane and so on.

On the optimization of sound absorption characteristics of porous sintered fibrous metal

Focusing the attention on a sintered fibrous metal sample,the sound absorption properties under different temperatures(from 20 ℃ to 500 ℃) and temperature gradients(-2.
