Description

101 The invention relates to devices: for burning toppia and may be. Used by DP teppovyh power plants. Known furnaces dp natural gas combustion, containing shielded prismatic combustion chamber with bitters 13 The disadvantage of these devices is the low reliability and formation in the combustion products of oxides of nitrogen due to the high temperatures of the gas flue. Fireboxes for burning natural gas are also known, which contain a shielded vertical adalatic combustion chamber with burners and installed above the double-sided shields, forming recirculation channels with the front wall of the furnace and communicating with the upper and lower sections of the combustion chamber 2. The disadvantage of this device is poor heat exchange between screens and torches due to weak luminosity. ti last. The goal invented - the intensification of heat transfer. The goal is achieved by those. that in the furnace for burning natural gas containing a shielded vertical prismatic combustion chamber with burners and two-light shields installed above the NIMV, forming two-light shields that recycle lUUOHHbie with the front wall of the goshsie, the upper and lower sections with the combustion chamber are equipped with a secondary - mi supply of natural gas. The axis of the burners can be placed 6t of the upper edge of the double-lighted screen 72 on. | The condition is 0.2-O, 3 height of the combustion chamber. The drawing shows a firebox, a longitudinal section. The fire chamber of a natural gas combustible contains a shielded vertical PriA 1 static combustion chamber 1 with burners 2 and installed above the last two-light shields 3, to form; With the front wall, 4 fireboxes, the recirculation channels 5, communicated with the upper and lower sections, respectively, with windows 6 and 7 with the combustion chamber 1. The recirculation channels 5 in the upper part are provided with natural gas supply nozzles 8. The axes of the burners 2 can be placed from the upper edge of the double-lighted screen 3 at a distance, composition. It is 0.2-0, .3 height of chamber 1 burned. The firebox works as follows; The gas-air mixture expired from the burners 2, ejects high-temperature flue gases from 1 sr) through window 6 to the upper part of the re-. circulation channels 5, where through the pipe 8 pfdatch natural gas. High temperatures and low oxygen content in the recirculation gases create conditions for the decomposition of methane and other hydrocarbons of natural gas with the release of soot particles, which act together with the gas-air mixture through the window 7 into the combustion chamber 1 to increase the luminosity of the flame, which contributes to the intensification of heat exchange. Studies have shown that the greatest effect of the decomposition of natural gas is achieved by placing the burner axes from the upper edge of a double-lined screen at a distance of 0.2-0.3 of the height of the combustion chamber.

Claims (2)
