An inner ring of an annular shell of the big fire burner is an inverted frustum which forms an angle between 20 and 80 DEG with a horizontal plane, and 1 to 5 fire exhaust holes are formed on the inner ring. One end of the mixing tube of the big fire burner is connected with the annular shell and communicated with an inner cavity of the annular shell, while the other end is communicated with a big fire nozzle which is arranged on the lower part of the water collector. The small fire burner comprises a frustum cap shell and an inner cavity of the frustum cap shell, wherein 1 to 5 fire exhaust holes are formed on external side face of the frustum cap shell, and the inner cavity of the frustum cap shell is communicated with a small fire nozzle which is positioned on the lower part of the water collector by a mixing tube of the small fire burner. The inner flame energy-concentrating riser pipe type gas burner has the advantages of reasonable structure, high thermal efficiency, material conservation, convenient processing, excellent energy-saving effect, less exhaust emission and the like.

The invention relates to a coal bunker. The coal bunker comprises an upper coal bunker body and a lower coal bunker body which is connected with at least one air pipe, the air pipe injects air in the lower coal bunker body from bottom to top, the air pipe is connected with an air supply device used for supplying air into the lower coal bunker body, the air pipe is provided with a control device, and the air in the air pipe enters the lower coal bunker body under the control of the control device. The coal bunker has the advantages that the air in the air supply device enters the lower coal bunker through the air pipe under the control of the control device, coal blocked in the lower coal bunker body can be loosened by means of kinetic energy produced by the air flowing from bottom to bottom, continuity of coal feeding of a boiler is guaranteed, combustion conditions of the boiler are stabilized greatly, work intensity is reduced, safety is good, and manpower is saved.

The invention discloses a suspension three-cavity aluminum burner, and relates to the technical field of combustors. The suspension three-cavity aluminum burner is composed of a burner main body, a mixing cavity and a burner cap; the interior of the burner main body is provided with the mixing cavity, and the burner cap is installed on the surface of the mixing cavity; the burner main body is composed of an outer ring body and a center ring body; the mixing cavity is composed of an outer ring mixing cavity, a middle ring mixing cavity and a center mixing cavity, the outer ring mixing cavity isarranged on the inner side of the outer ring body, the middle ring mixing cavity is arranged on the inner side of the center ring body, and the center mixing cavity is arranged in the center of an inner ring of the center ring body; and the outer surface of the outer ring body is fixedly connected with an outer ring arc pipe. According to the suspension three-cavity aluminum burner, a nozzle andan injection pipe are arranged above a combustor panel or a water pond, primary air, secondary air and third air required from combustion are guided in from the upper portion of the panel or the waterpond, the problem that injection of the combustor is conducted from the interior of a bottom shell is solved, and complete upper air feeding combustion is achieved.

The invention discloses a system for automatically controlling garbage feeding. The system comprises a first radio frequency admittance material level switch, at least one second radio-frequency admittance material level switch and an ultrasonic sensor, wherein the first radio frequency admittance material level switch is provided with a low material level switch and a high material level switch;the low material level switch and the high material level switch are arranged on a drum feeding port material well wall from bottom to top; a flange sleeve is arranged at the mounting position of thefirst radio frequency admittance material level switch; a first radio frequency admittance material level meter is fixed on the flange sleeve and can be movably adjusted; the second radio-frequency admittance material level switch is arranged on the drum discharging port material well wall, and stops upper and lower feeding and sending an alarm of a high material level at the lower position underthe condition of high material level; and the ultrasonic sensor comprises a first ultrasonic sensor and a second ultrasonic sensor.
