The demand for efficient, clean energy has encouraged wider use of natural gas and a renewed interest in surface combustion. The sintered metal fiber burner is a permeable surface medium for surface combustion of premixed gas and air. Its potential of handling radiant modes of up to 5,000 kW/ m{sup 2} (1.6 million Btu/h{center_dot}ft{sup 2}) allows for a powerful radiant flux with efficiencies up to 60% in a very compact and durable design. It has found ready acceptance in applications such as drying, curing, baking, grilling, and other processes where direct radiant heat is an immediate benefit. Now, a new generation of metal fiber burners has been developed: the knitted metal fiber burner. This new type of burner combines the excellent combustion performance of the sintered mat with the advantages of a textile. It is flexible, easy to mount, and offers total thermal expansion control. It handles a span of firing intensities from 100 kW/m{sup 2} (32,000 Btu/h{center_dot}ft{sup 2}) in radiant mode up to 5,000 kW/m{sup 2} (1.6 million Btu/h{center_dot}ft{sup 2}) in blue flame mode. This span of outputs is achieved with very low NO{sub x} (less than 20 ppm at 0% O{sub 2}) and CO (less than 30 ppm at 3,500 kW/m{sup 2} [1.2 millions Btu/h{center_dot}ft{sup 2}] combustion intensity at 0% O{sub 2}) emissions. The easy and compact burner design allows for immediate applications in fire tube boilers, steam generators, water heaters, hot air generation, and process heaters.
