FIELD: power engineering.SUBSTANCE: invention relates to devices intended for overheating of water steam at organizing of working process of steam, gas-vapour power units and gas pumping units. The countercurrent hydrogen-oxygen combustor contains igniter, fuel nozzles, flame conic stabiliser and base steam separation circuit. In the end part of the base steam separation circuit the low-temperature flow is divided into three channels - base steam supply circuit, mixing circuit and conic stabiliser cooling circuit. The countercurrent hydrogen-oxygen chamber also has the system of tangential twisting devices, compensator of thermal expansion of flame tube, throttle regulator, pre-mixing chamber in the igniting device, collector of uniform distribution of fuel among the nozzles, and collector of oxidizing agent distribution in the mixing circuit.EFFECT: invention is aimed at decrease of hydraulic losses in the component supply system, possibility of maintaining of initial degree of twisting along the length of flame tube, compensation of a thermal expansion of flame tube and regulation of oxidizing agent flow rate, decrease of non-uniformity of fuel distribution among nozzles, non-uniformity of concentration of oxidizing agent in the mixing circuit, decrease of probability of occurrence of explosive situation.7 cl, 4 dwg |
