Abstract

1. Конструкция котла с циркуляционной схемой горения, выполненная таким образом, что подаваемые топливо и воздух для горения в топочную камеру из горелок, расположенных у множества положений на стенках топочной камеры, образующих прямоугольное сечение, в процессе горения образуют вихревой поток, ! в которой подающие воздух компоненты расположены около подвергающихся воздействию пламени участков поверхностей стенок топочной камеры, к которым приближаются или входят с ними в контакт факелы пламени, создаваемые соответствующими горелками, для создания областей с более высокой концентрацией воздуха, чем на периферии этих областей. ! 2. Конструкция котла по п.1, в которой области с более высокой концентрацией воздуха создают так, чтобы перекрыть зону горения в восстановительной атмосфере внутри топочной камеры в вертикальном направлении. ! 3. Конструкция котла по п.1, в которой подающие воздух компоненты вводят вторичный воздух низкого давления из смежных горелок через перепускные каналы. ! 4. Конструкция котла по п.1, в которой подающие воздух компоненты расположены вокруг удаляющих шлак сопел. ! 5. Конструкция котла по п.2, в которой подающие воздух компоненты вводят вторичный воздух низкого давления из смежных горелок через перепускные каналы. ! 6. Конструкция котла по п.2, в которой подающие воздух компоненты расположены вокруг удаляющих шлак сопел. ! 7. Конструкция котла по п.3, в которой подающие воздух компоненты расположены вокруг удаляющих шлак сопел. 1. The design of the boiler with a circulating combustion circuit, made in such a way that the supplied fuel and combustion air to the combustion chamber from burners located at many positions on the walls of the combustion chamber, forming a rectangular section, form a vortex flow during combustion,! in which the air supply components are located near the exposed parts of the surfaces of the walls of the combustion chamber, which are approached or come into contact with flame torches created by the respective burners to create areas with a higher air concentration than at the periphery of these areas. ! 2. The design of the boiler according to claim 1, in which areas with a higher concentration of air are created so as to block the combustion zone in the reducing atmosphere inside the combustion chamber in the vertical direction. ! 3. The design of the boiler according to claim 1, in which the air supply components introduce secondary low-pressure air from adjacent burners through the bypass channels. ! 4. The design of the boiler according to claim 1, in which the air supply components are located around the slag-removing nozzles. ! 5. The boiler design according to claim 2, in which the air-supplying components introduce low-pressure secondary air from adjacent burners through the bypass channels. ! 6. The boiler design according to claim 2, in which the air supply components are located around the slag-removing nozzles. ! 7. The boiler design according to claim 3, in which the air supply components are located around the slag-removing nozzles.
