Abstract
Устройство для дожигания газов в твердотопливных котлах длительного горения относится к способам сжигания топлива и конструкциям печей и может быть использовано для сжигания любого вида топлива. Представляет собой цилиндрический корпус с топочной камерой, в которой размещена теплообменная секция с камерой дожига и цилиндрический конвективный блок. Внутри цилиндрического корпуса котла находится водяная рубашка, топка, зольник, колосники, камера дожигания газов, обмурованная огнеупорным материалом, с установленной в ней трубкой Вентури. Цилиндрический топочный блок соединён с цилиндрическим конвективным блоком патрубком, в который впрессована трубка Вентури, в которой происходит второй этап дожига газов и снижение выбросов оксида азота и оксида углерода. Снаружи находятся загрузочная дверца, дверца зольника, манометр и термометр выходящей воды, труба подвода воздуха, труба отвода горячей воды, труба подвода обратной воды. Цилиндрический корпус топочной камеры соединён с цилиндрическим конвективным блоком, в котором находится дымоход и трубы подвода обратной воды. Снаружи находятся боковая дверца прочистки, верхняя крышка прочистки дымоходных путей, дымоход, труба подвода обратной воды. Сущность изобретения характеризуется техническим результатом: для выравнивания температуры в топке и в камере дожига последняя обмурована огнеупорным материалом; для снижения избытка воздуха в камере дожига внедрён второй этап дожига газов.A device for afterburning gases in solid fuel boilers for long burning relates to methods of burning fuel and furnace designs and can be used to burn any type of fuel. It is a cylindrical body with a combustion chamber, in which a heat exchange section with a afterburner and a cylindrical convection unit are placed. Inside the cylindrical body of the boiler there is a water jacket, a furnace, an ash pan, grates, a gas afterburner chamber, surrounded by refractory material, with a venturi installed in it. A cylindrical furnace block is connected to a cylindrical convective block by a nozzle into which a Venturi tube is pressed in, in which the second stage of gas afterburning and reduction of emissions of nitric oxide and carbon monoxide take place. Outside, there is a loading door, an ash pan door, a pressure gauge and a thermometer for outgoing water, an air supply pipe, a hot water discharge pipe, and a return water supply pipe. The cylindrical body of the combustion chamber is connected to a cylindrical convective block, in which there is a chimney and pipes for supplying return water. Outside, there is a side door for cleaning, the top cover for cleaning chimney paths, a chimney, a pipe for supplying return water. The invention is characterized by the technical result: to equalize the temperature in the furnace and in the afterburner, the latter is lined with refractory material; To reduce the excess air in the afterburner, a second stage of gas afterburning was introduced.
