Description

Изобретение относится к области энергетики, в частности к топочным камерам котельных агрегатов. *The invention relates to the field of energy, in particular to the combustion chambers of boiler units. *

Известна топочная камера котельного агрегата, содержащая холодную воронку с наклонными скатами и размещенный'под последней шлаковый комод, в одной из стенок которого установлены воздушные сопла, наклонные под углом, равным углу наклона противолежащего ската воронки fl ].A furnace chamber of a boiler unit is known containing a cold funnel with inclined slopes and a slag chest placed under the last one, in one of the walls of which there are air nozzles inclined at an angle equal to the angle of inclination of the opposite slope of the funnel fl].

Недостаток этого устройства - боль шие потери тепла с механическим недожогом топлива в шлаке при сжигании пыли, содержащей крупные фракции.The disadvantage of this device is the large heat loss with mechanical burning of fuel in the slag during the combustion of dust containing large fractions.

Целью изобретения является повышение эффективности сжигания топлива путем дожигания крупных фракций.The aim of the invention is to increase the efficiency of fuel combustion by burning large fractions.

Для достижения этого топочная камера снабжена дополнительными воздушными наклонными соплами, установленными на противолежащей стенке шлакового комада и в шахматном по2 рядке относительнс основных воздушных сопл, причем угол наклона дополнительных сопл равен углу наклона про тиволежащего ската воронки.To achieve this, the combustion chamber is equipped with additional air inclined nozzles mounted on the opposite wall of the slag comad and staggered in relation to the main air nozzles, the angle of inclination of the additional nozzles being equal to the angle of inclination of the opposite slope of the funnel.

На фиг. 1 изображена описываемая камера, общий вид; на фиг. 2 - сечение А-А на фиг. 1.In FIG. 1 shows the described camera, General view; in FIG. 2 is a section AA in FIG. 1.

Топочная камера 1 содержит холод-, ную воронку 2 с наклонными скатами и шлаковый комод 3, в одной из стенок которого установлены воздушные сопла 4, наклонные под углом, равным углу наклона противолежащего ската воронки 2.The combustion chamber 1 contains a cold, funnel 2 with inclined slopes and a slag chest 3, in one of the walls of which there are air nozzles 4 inclined at an angle equal to the angle of inclination of the opposite slope of the funnel 2.

Топочная камера 1 снабжена дополнительными воздушными наклонными соплами 5, установленными на противолежащей стенке шлакового комода 3 и в шахматном порядке относительно основных сопл 4, причем угол наклона сопл 5 равен углу наклона противолежащего ската воронки 2.The combustion chamber 1 is equipped with additional air inclined nozzles 5 mounted on the opposite wall of the slag chest 3 and in a checkerboard pattern relative to the main nozzles 4, and the angle of inclination of the nozzles 5 is equal to the angle of inclination of the opposite slope of the funnel 2.

Устройство работает следующим образом. В топочную камеру 1 поступают воздух и пыль, крупные фракции которой сепарируются и выпадают на скаты холодной воронки 2, где попадают в поток горячего воздуха, выходящего из сопл 4 и 5, установленных в верхней части комода 3 на двух противоположных стенках его в шахматном порядке, причем угол наклона сопл 4 и 5 равен соответственно углу наклона противолежащих скатов воронки 2.The device operates as follows. Air and dust enter the combustion chamber 1, large fractions of which are separated and fall onto the slopes of the cold funnel 2, where they fall into the stream of hot air leaving the nozzles 4 and 5 installed in the upper part of the chest of drawers 3 on two opposite walls in a checkerboard pattern, moreover, the angle of inclination of the nozzles 4 and 5 is equal respectively to the angle of inclination of the opposite slopes of the funnel 2.

При активном омывании горячим воздухом и увеличенном времени пребывания- в пределах топочной камеры 1 сепарирующиеся крупные фракции топлива выгорают, вследствие чего тепловые потери котлоагрегата с механическим недожогом топлива снижаются .With active washing with hot air and an extended residence time, large fuel fractions burn out within the combustion chamber 1 and burn out, as a result of which the heat losses of the boiler with mechanical underburning of fuel are reduced.

Claims

The invention relates to the field of energy, in particular to the combustion chambers of boiler units. The furnace chamber of the boiler room A.G. is a regatta containing a cold funnel with inclined slopes and a slag chest placed under the latter, in one of the walls of which air nozzles are mounted inclined at an angle equal to the inclination angle of the opposite slope of the funnel 1 j. The disadvantage of this device is the greater heat losses due to mechanical underburning of fuel in the slag during the combustion of a ditch containing large fractions. The aim of the invention is to increase the combustion efficiency of the fuel by post-burning coarse fractions. To achieve this, the furnace chamber is equipped with additional air-inclined nozzles mounted on the opposite wall of the slag comad and in staggered order relative to the main air nozzles, the angle of inclination of the additional nozzles being equal to the angle of inclination of the opposite slope of the funnel. FIG. j depicts the camera described, general view; in fig. 2 is a section A-A in FIG. 1. The furnace chamber 1 contains a cold funnel 2 with inclined slopes and a slag chest of drawers 3, in one of the walls of which air nozzles 4 are installed, inclined at an angle equal to the angle of inclination of the opposite slope of the funnel 2. Tube chamber 1 is equipped with additional air nozzles 5, mounted on the opposite wall of the slag dresser 3 and in staggered order relative to the main nozzles 4, the angle on the “claw of the nozzles 5 being equal to the angle of inclination of the opposite slope of the funnel 2. The device works as follows. Air and dust enter the combustion chamber 1, large fractions of which are separated and fall out onto the) cold funnel 2, where the flow is in a stream of hot air, out of nozzles 4 and 5, installed S of the upper part of the chest 3 aa of two opposite walls e in a checkerboard pattern, with the angle of inclination of the nozzles 4 and 5 being equal, respectively, to the angle of inclination of the opposite slopes of the funnel

2. With the active omission of hot air and an extended residence time — Within the furnace chamber 1, the separated large facies of fuel burn out, due to the heat loss of the boiler unit due to under-burning of the fuel. Claims of the invention A boiler chamber furnace containing a cold funnel with 74 inclined slopes and a slag chest placed under the latter, in one of the walls of which is installed, eject nozzles that are inclined at an angle equal to the inclination angle of the opposite slope of the funnel, which is different from increase the efficiency of fuel combustion by afterburning large fractions; it is equipped with additional air inclined nozzles mounted on the opposite wall of the slag chest and in chess order relative to main air nozzles, and the angle of the additional nozzles is equal to the angle of inclination of the opposite slope of the funnel.
