Abstract

1. Дежурная горелка, содержащая сопло, узел ввода газовоздушной смеси, узел ввода дополнительного воздушного потока, корпус камеры смешения с боковым отверстием, полость которого соединена с полостью корпуса форкамеры через проходное отверстие, в котором установлен электрод искрового запальника, отличающаяся тем, что форкамера размещена внутри камеры смешения, узел ввода газовоздушной смеси соединен с корпусом камеры смешения и с корпусом форкамеры через боковое отверстие в корпусе камеры смешения, которое разделено верхним краем кольцевого выступа проходного отверстия корпуса форкамеры, и который с наружной стенкой корпуса форкамеры, внутренней стенкой корпуса камеры смешения и с конусной поверхностью сопла для ввода дополнительного воздушного потока в полость корпуса форкамеры, образует круговой канал для подачи в полость корпуса форкамеры газовоздушной смеси, а электрод искрового запальника выполнен в виде трубки, соединенной с узлом ввода дополнительного воздушного потока и проходящей соосно сквозь камеру смешения, форкамеру и сопло, образуя круговой искровой зазор между срезом сопла и трубкой.2. Дежурная горелка по п. 1. отличающаяся тем, что в круговом канале в месте подачи газовоздушной смеси в полость корпуса форкамеры установлена кольцевая система сопел, которая с наружной стороны сопряжена с основанием корпуса форкамеры, а с внутренней стороны сопряжена со срезом сопла, причем оси огневых отверстий кольцевой системы сопел могут располагаться как угодно в полости форкамеры относительно ее оси.3. Дежурная горелка по п. 1. отличающаяся тем, что размер искрового зазора от поверхности трубки электрода искрового за1. An on-site burner containing a nozzle, an air-gas mixture inlet unit, an additional air stream inlet unit, a mixing chamber body with a side hole, a cavity of which is connected to a chamber cavity of the prechamber through a passage in which a spark ignition electrode is installed, characterized in that the prechamber is located inside the mixing chamber, the gas-air mixture input unit is connected to the mixing chamber housing and to the prechamber housing through a side opening in the mixing chamber housing, which is divided by the upper edge of the mixing chamber the central protrusion of the passage opening of the prechamber housing, and which with the outer wall of the prechamber housing, the inner wall of the mixing chamber housing and the conical surface of the nozzle for introducing additional air flow into the chamber cavity of the prechamber, forms a circular channel for supplying a gas-air mixture to the chamber chamber and the spark electrode the igniter is made in the form of a tube connected to an additional air flow input unit and passing coaxially through the mixing chamber, prechamber and nozzle, forming a circular spark th gap between the nozzle exit and the tube. 2. The duty burner according to claim 1. characterized in that in the circular channel at the place of supply of the gas-air mixture into the cavity of the prechamber housing, an annular nozzle system is installed, which is externally coupled to the base of the prechamber housing, and on the inner side is interfaced with a nozzle cut, and the axis of the fire the holes of the annular system of nozzles can be positioned as desired in the cavity of the prechamber relative to its axis. 3. The duty burner according to claim 1. characterized in that the size of the spark gap from the surface of the tube of the spark electrode

Claims
