FIELD: power industry.SUBSTANCE: mixing head of the methane-oxygen steam generator contains jet nozzles, an ignition device, a housing and a fire bottom. The mixing head has two cascades of fuel nozzles which are located at different radial distances. The fuel nozzles of the first cascade are designed in such a way that crossing of their axes with the longitudinal axis of the oxidiser nozzle is located from the fire bottom at the distance 5÷7 output diameters of the oxidiser nozzle, and the fuel nozzles of the second cascade are located from the fire bottom at the distance 10÷15 output diameters of the oxidiser nozzle.EFFECT: invention allows to increase efficiency of burning, service life of the mixing head and the steam generator in general.4 dwg |
