Description

Изобретение относитс  к области 9Hej тетики и может быть использовано на теп ловых электростанци х, содержащих Kqгельные агрегаты с регенеративными воз духоподогревател ми.. Известны котельные агрегаты, соде1 жащие тр&кт рециркул ции дымовых газов с дымососом и регенеративный воздухоподогреватель , воздушный отсек которого в зоне аксиальных уплотнений снабжен отводом перетечек ClJНедостаток такого агрегата - низка  экономичность, так как улавливаемый отводом перетечек воздух не используетс  дл  сгорани  топлива. Цель изобретени  - повышение экономичности . Это достигаетс  тем, что отвод перетечек подключен к дымЬсосу. На фиг. 1 изображена принципиальна  схема котельного агрегата; на фиг. 2 разрез А-А на фиг. 1. Котельный агрегат содержит топоЧную камеру 1 с горелка1 и 2, конвективный газоход 3 и регенеративный воздухоподогреватель 4, соединенный газоходом 5 отход щих дымовых газов, включающим тракт 6 рециркул ции, с дымососом 7, Регенеративный воздухоподогреватель 4 разделен радиальными плитами 8 на воздушный 9 и газовый 10 отсеки. Воздушный отсек 9 включен в воздуховод 11, на Й1ходе которого установлен дутьевой вентил тор 12, а выход соединен с горелками 2. Газовый отсек 10 включен в газоход 5 отход щих дымовых газов. Регенеративный воздухоподогреватель 4 соде} жит систему радиальных 13, периферийных 14 и аксиальных 15 уплотнений, преп тсгвующщс перетечкам воздуха и газа. Воздушный отсек 9 в зоне аксиальных уплотнений 15 снабжен отводом 16 перетечек, подключенным к дымососу 7, Котельный агрегат работает следующим образом. . Гор чие дымош 1е газы, образующиес  в топочной камере 1,. подвод тс  газохоThe invention relates to the field of 9Hej tetics and can be used on thermal power plants containing Kqgel units with regenerative air heaters. Known boiler units containing flue gas recirculation with exhaust fan and a regenerative air heater, the air compartment of which is in the area Axial seals are provided with diversion of ClJ overflows. The disadvantage of such a unit is low profitability, since the air caught by the diversion of overflows is not used to burn fuel. The purpose of the invention is to increase efficiency. This is achieved by the fact that the diversion of overflows is connected to the smoke pump. FIG. 1 is a schematic diagram of a boiler unit; in fig. 2, section A-A in FIG. 1. The boiler unit contains a top chamber 1 with a burner 1 and 2, a convective duct 3 and a regenerative air heater 4 connected by a duct 5 of exhaust flue gases, including a recirculation path 6, with a smoke exhauster 7, the regenerative air heater 4 is divided by radial plates 8 into air 9 and gas 10 compartments. The air compartment 9 is included in the air duct 11, on whose entrance there is a blower fan 12, and the outlet is connected to the burners 2. The gas compartment 10 is included in the duct 5 of the exhaust flue gases. Regenerative air heater 4 contains a system of radial 13, peripheral 14 and axial 15 seals, which prevents the flow of air and gas. The air compartment 9 in the zone of axial seals 15 is provided with a branch 16 of the overflows connected to the exhaust fan 7, the boiler unit works as follows. . Hot smoke 1e gases formed in the combustion chamber 1 ,. gasho is supplied
