Power and spectral characteristics of radiation of a porous torch with the converter on a basis of ceramic-metal Ni-Al compounds were investigated. It is established that the general radiant conversion efficiency of a torch, working with natural gas, reaches 60% from caloric content of fuel, and power density of a stream of radiation, 30 Vt/sm2. It is shown that up to 65% of energy of radiation is concentrated in a wavelength range of 3-11 microns. From the analysis of the received data it follows that streams of radiation from a firm surface of the converter and from gaseous products of burning have comparable values. The parity of streams varies depending on a configuration and geometry of the converter and speed of supply of a fuel mix that is accounted by changes the thermal mode of the filtration burning wave. Here, the effective radiating temperature of products of burning and a firm surface are defined by power exchange of parameters between the gas stream and the converter.
