Description

The invention relates to furnace technology and can be used in industrial heat and power engineering.

A device for burning fuel in a pulsating stream, co. an injector-supplied chamber of ignition with a diffuser outlet section connected to the resonance tube, and air inlets connected to the diffuser section of the chamber and placed at an angle to its axis D1}.

However, the device has insufficient thermal power.

The purpose of the invention is to increase the thermal power of the device by means of intensifying the primary mixture formation.

The goal is achieved by the fact that the air inlet nozzles are set tangentially to an imaginary circle located in the chamber of ignition, and the angle between the axes of the latter and the said nozzles is 15-75 °. In addition, the air inlets are provided with inlet and outlet confused ports.

FIG. 1 shows the proposed device, a general view; in fig. 2 view A in FIG. one.

The device for burning fuel in a pulsating flow comprises an ignition chamber 1 with a nozzle 2 and a diffuser outlet section 3 connected to a resonant tube 4 to which air inlet nozzles 5 are connected, placed at an angle (15-75) to the axis of the ignition chamber 1 and installed tangentially to an imaginary circle 6 located in the ignition chamber 1. Air inlets 5 are made with confused inlet and outlet sections 7 and 8, respectively. The device works as follows. A pilot light is introduced into the ignition chamber 1, and fuel is supplied to the nozzle 2. Due to the presence of the resonant tube 4, a self-oscillating flow of gas with pulsations of gas pressure and its velocity is established. Air into the ignition chamber 1 is supplied through nozzles 5. Air is introduced into the atomized fuel flow, simultaneously creating a rotating vortex inside chamber 1, which leads to intensification of mixing, shortening of the flare, stabilization of the pulsation mode, and, as a result, increase of the thermal power of the installation.

The device almost completely avoids underburning and reduces

0 coefficient of excess air to 1,021, 05, as well as increase the heat output by 10-20%.
