(54) ТОПКА ПАРОГЕНЕРАТОРА(54) STEAM GENERATOR TOP

1one

Изобретение относитс к конструкци м топочных устройств и может быть использовано в топках парогенераторов с П-образной компановкой.The invention relates to the design of furnaces and can be used in furnaces of steam generators with a U-shaped arrangement.

Известны топки парогенераторов, содержащие экранированную вертикешьную . призматическую камеру с расположенными на ее боковых стенках горелками, а на задней стенке окном дл выхода .Known furnaces of steam generators containing screened vertical. a prismatic chamber with burners located on its side walls, and an exit window on the rear wall.

Недостатком данных устройств sjaл етс неравномерна температура газа на выходе из топки (поверхность теплообмена половины топки со стороны окна меньше, чем поверхность теплообмена другой половины, в которую вход т потолочные экраны).The disadvantage of these devices is the uneven gas temperature at the exit from the furnace (the heat exchange surface of the furnace half of the window is smaller than the heat exchange surface of the other half, which includes ceiling screens).

Известна также топка парогенератора, содержаща экранированную вертикальную призматическую камеру с расположенными на ее боковых стенках горелками, а на задней стенке - окном дл выхода .A steam generator furnace is also known, which contains a shielded vertical prismatic chamber with burners located on its side walls and a window for exit on the rear wall.

Равномерность температуры на выходе из топки достигаетс тем, что в горелки , расположенные в половине камеры со стороны окна дл выхода газа, подаетс меньше топлива, чем в горелки, расположенные в другой половине.The uniformity of the temperature at the outlet of the furnace is achieved by the fact that less fuel is supplied to the burners located in half of the chamber on the side of the gas outlet window than to burners located in the other half.

Недостатком данного устройства вл етс сложность ведени процесса, что приводит к снижению экономичности, а также необходимость применени нескольких типов горелок.Цель изобретени - повышение экономичности .The disadvantage of this device is the complexity of the process, which leads to lower efficiency, as well as the need to use several types of burners. The purpose of the invention is to improve efficiency.

Указанна цель достигаетс тем, что горелки, расположенные в половине камеры со стороны окна дл выхода газа, установлены ниже горелок, расположенных .в другой ее половине, на рассто ние, составл ющее 0,2-1,5 ширины кал1еры.This goal is achieved by the fact that the burners, located in half of the chamber on the side of the gas outlet, are installed below the burners, located in its other half, by a distance of 0.2-1.5 caliper widths.

На чертеже изображена топка, продольный разрез.The drawing shows the furnace, a longitudinal section.

Claims

The firebox contains a shielded vertical prismatic chamber 1 with front, side, rear and ceiling walls 2-5, respectively. The burners 3 b and 7 are located on the side walls 3, and the rear wall 4 HQ has a window 8 for the exit of gas. Burners 6, located in half of chamber 1 on the side of window 8 for the exit of gases, are installed below burners 7, located in the other half of chamber I, at a distance of 0.2-1.5 times the width of chamber 1 The furnace works as follows. The fuel with air through the burners 6 and 7 enters the volume of chamber 1, where it burns. The flue gases generated during this move to the upper part of chamber 1, to the output window 8, giving its heat to the walls of chamber i, the flue gases of the torches of the burners 6 give up heat is half of the side walls 3 and the rear wall 4, and the ropertoK 7 flares - the other half of the side walls 3, the pedal wall 2 and the ceiling wall 5. Due to the location of the burners 6 below the burners 7 at a distance of 0.21, 5 the width of chamber 1, the heat-receiving surface for gas f kelov burners 6 equal on the heat-transmitting surface for gas torches of the burners 7, which provides the same f < ffluorine gas at the outlet of chamber 1. 35 Since the burners 6 and 7 receive fuel at the same rate, combustion management is facilitated, which makes it possible to burn fuel with the lowest mechanical and chemical losses and, consequently, increase the efficiency of the furnace. The invention of the steam generator Firebox, containing a shielded tical prismatic chamber with burners located on its side walls and a window for gas outlet on the back wall, so that, in order to increase efficiency, burners located in half of the chamber on the side of the gas outlet window, are installed below the burners, located in the other half, at a distance of 0.2-1.5 chamber widths.
