Description
Изобретение относитс к энергетике и может быть использовано дл котельных агрегатов.The invention relates to energy and can be used for boiler units.
Известен котеЛ, содержащий топку с конвективным газоходом, в котором расположены теплообл енные поверхности нагрева, газоход рециркул ции с дамососом 13A well-known boiler containing a furnace with a convective flue, in which heat-cooled heating surfaces are located, is a recirculation flue gas pipe with a diverter 13
Недостатком этой установки вл етс повышенное содержание окислов азота в уход щих газах.The disadvantage of this installation is the increased content of nitrogen oxides in exhaust gases.
Известен также котел, содержащий конвективную шахту, поворотньлй газоход и подключенный одним концом к последнему байпасный трубопровод, снабженный нагнетателем и устройством дл ввода аммиака 2.Also known is a boiler containing a convective shaft, a rotary duct and connected at one end to the last bypass pipeline equipped with a supercharger and an ammonia injection device 2.
Недостатком известного котла в- л ётс сложность конструкции, приспособлений ввода аммиака, обусловленна высокой температурой газового потока и низкой эффективностью действи присадки, св занной с частичным разложением ашмиа а в пристечной зоне каналов дл подачи его в газо- , ход.A disadvantage of the known boiler is the complexity of the design, ammonia injection devices, due to the high temperature of the gas stream and the low efficiency of the additive, due to the partial decomposition of ash in the stent channels for supplying it to the gas and passage.
Целью изобретени вл етс снижение содержани окислов азота и упрощение конструкции.The aim of the invention is to reduce the content of nitrogen oxides and simplify the design.
Указанна цель достигаетс тем, что байпасный трубопровод подключен другим концом к конвективной шахте, а устройство ввода аммиака расположено перед нагнетателем.This goal is achieved by the fact that the bypass pipeline is connected at the other end to the convective shaft, and the ammonia inlet device is located in front of the supercharger.
На чертеже схематически представлен предлагаемый котел, общий йид.The drawing shows schematically the proposed boiler, common Yid.
Котел содержит конвективную шах- ту 1, поворотный газоход 2 и подклю10 ченный одним концом к последнему байПасный трубопровод 3, снабженный нагнетателем 4 и устройством 5 ввода аммиака. Байпасный трубопровод 3 подключен другим концом к конвектив15 ной шахте 1, .а устройстро 5 ввода аммиака расположено перед нагнетателем 4.The boiler contains a convective shaft 1, a rotary duct 2 and one end connected to the last bypass pipeline 3, equipped with a blower 4 and an ammonia inlet device 5. The bypass pipeline 3 is connected at the other end to the convective shaft 1, and the ammonia injection device 5 is located in front of the blower 4.
Работа котла происходит следующим образом.The work of the boiler is as follows.
2020
В дымовых газах при сжигании топлива содержатс окислы азота. При движении газов по газовсаду тракту котла они охлс1ждаютс , отдава тепло поверхност м нагрева, и при достиже25 нии ими температуры пор дка 10001050 С .кним подают газы рециркул ции по байпасному трубопроводу 3.The combustion gases contain nitrogen oxides in flue gases. When gases move along the gas channel to the boiler path, they are cooled, giving off heat to the heating surfaces, and when they reach a temperature of about 10001050 ° C. Recirculation gases are fed through the bypass pipeline 3.
С помощью устройства 5 ввод т аммиак в газы рециркул ции, который Using device 5, ammonia is introduced into the recirculation gases, which
