In a method for the combustion of a fuel, a fuel or a premixed combustible mixture is introduced into a combustion space as a combustible fluid open jet. The velocity of the open jet is selected in such a way that it is impossible for a stable flame front to form, i.e. is in any event greater than the flame front velocity, and that, on account of a jet pump effect, flue gas is mixed into the combustible fluid jet from the combustion chamber in a jet-induced recirculation internally within the combustion chamber. The admixed flue gas dilutes and heats the combustible fluid. The heating causes the spontaneous ignition temperature to be exceeded, and a low-pollutant volumetric flame is formed in a highly dilute atmosphere.

An apparatus for cooking food with infrared radiation includes an infrared energy emitter for emitting the infrared radiation, and a grid in close proximity to the infrared energy emitter. A first side of the grid can be for supporting the food at a position so that at least some of the infrared radiation will cook the food. A second side of the grid can be sufficiently close to the emitting side of the emitter for substantially restricting any airflow in any space between the second side of the grid and the emitting side of the emitter. Partitions of the grid can operatively segregate the emitting side of the emitter into segments, which can provide a substantially uniform distribution of infrared radiation.

A high-voltage circuit breaker includes two arcing contacts, which are capable of moving relative to one another along an axis, an insulating nozzle, a heating volume for accommodating quenching gas, a heating channel, and an overpressure valve.

The invention is related to a thermally insulated and moisture-repellent textile structure, consisting of 1. an inner layer (contact skin): made of moisture-absorbance and sweat-repellant ultrafine fiber; 2. a middle layer: made of thermally insulated and anti-static metal yarns combined with moisture-absorbant and sweat-repellent ultrafine fibers; 3. an outer layer: moisture-absorbant and breathable pure cotton. When such textiles are applied to apparels like underwears, sweaters or jackets, the ultrafine fibers in the inner layer can completely absorb excessive water molecules on skin surface. When these water molecules that carry body heat pass through the middle layer, through the dual functions of the metal yarns of thermal insulation and the ultrafine fibers of moisture absorbance and sweat repellency, the water molecules are completely absorbed by the outer layer of pure cotton and repelled from the body. The body heat is conserved between the middle layer and human body. Thus, when such textile is worn, besides the anti-static and anti-bacteria property of the metal yarns, body dryness and comfort can be kept at a constant body temperature. It greatly improves the textile in the effect of moisture-absorbance and sweat-repellency and thermal insulation.
