Description

Уже известны устройства дл  ввода вторичного воздуха под давлением в топку парового котла с жаровой трубой дл  завихрени  газов за пределами топочной камеры .Devices are already known for introducing secondary air under pressure into the furnace of a steam boiler with a flame tube for the turbulence of gases outside the combustion chamber.

Отличительна  особенность предлагаемого устройства состоит в том, что в нем подача вторичного воздуха дл  завихрени  газов осущег ствл етс  в пределах топочной камеры над слоем топлива в зоне высоких температур.A distinctive feature of the proposed device is that in it the supply of secondary air for the turbulence of gases is carried out within the furnace chamber above the fuel layer in the high temperature zone.

Дл  этого в устройстве, 1схематн,чески изображенном на фиг. 1-3;в трех проекци х, применены распо;ложенные по бокам а олоспиковой решетки две трубы / и со щел ми 2.For this, in the device, 1 schematically, as shown in FIG. 1-3; in three projections, two pipes located at the sides of the Olospik lattice / and with slot 2.

Через трубы / и 5 в топку котла подаетс  под давлением подогретый воздух. Струн воздуха, выход щие из щелей 2 трубы /, направл ютс  вверх по касательным к поверхности жаро-вой трубы.Through pipes I and 5, heated air is supplied under pressure into the boiler furnace. The air strings extending from the slots 2 of the pipe / are directed upwards along the tangents to the surface of the heat pipe.

Натолкнувшись на стенку топки, воздух движетс  вдоль нее по винтовой линии, увлека  за собой топочные газы. Струи воздуха, выход щие из щелей 2 трубы 3, направл ютс  параллельно слою топлива. Таким образом, в топке происходит непрерывна  циркул ци  газов под действием т ги по винтовой линии. При этом увеличиваетс  путь прохождени  газов в топке, улзчшаетс  их перемешивание 1 уменьшаютс  потери тепла вследствие химической и механической неполноты сгорани .Having encountered the wall of the firebox, the air moves along it along a helical line, carrying the flue gases with it. Air jets emerging from the slots 2 of the pipe 3, are directed parallel to the layer of fuel. Thus, in the furnace, the gases are continuously circulating under the action of helium through the helix. In this case, the path of passage of gases in the furnace increases, their mixing is improved; 1, heat loss due to chemical and mechanical incomplete combustion decreases.

Предмет изобретени Subject invention

Устройство дл  ввода вторичного воздуха под давлением в топку парового котла с жаровой трубой, о Тг л п ч а ю щ е е с   прпмепением расположенных вдоль топки по бокам колосниковой решетки двух труб со щел ми, направл ющими струк воздуха из одной трубы параллельно слою топлива, а из другой-вверх по касательным к поверхности жаровой трубы.A device for injecting secondary air under pressure into the furnace of a steam boiler with a flame tube, about a lamber, with the two pipes arranged along the side of the grate, with air pipes from one pipe parallel to the fuel layer and from the other upwards tangential to the surface of the flame tube.
