Description
Изобретение относитс к теплоэнергетике и может быть использовано в воздухоподогревател х котельных агрегатов .This invention relates to a power system and can be used in air preheaters of boiler units.
Известны воздухоподогреватели, содержащие последовательно уставовленные по ходу дымовых газов секции и.предвключенный по воздуху калорифер , включенный в паровой контур СИAir heaters are known that contain sections sequentially installed along the flue gas and an air-heated heater included in the SI steam circuit.
Недостаток известного воздухоподогревател состоит ,в низкой эконсмичности , вследствие уменьшени расхода пара через цилиндры низкого .давлени турбины.A disadvantage of the known air preheater is, at low exonomicity, due to a reduction in steam consumption through low pressure turbine cylinders.
Наиболее близким из известных технических решений к предлагаемому вл етс воздухоподогреватель, содержащий последовательно установленные в газоходе теплообменныё секции, сообщенные по воздуху переточными коробами и подключенные по схеме противотока к подающему воздуховоду с установленньлм в нем калорифером, греюща лини которого соединена с вод ным контуром, снабженным насЬсом и теплообменником 2).The closest of the known technical solutions to the proposed invention is an air heater containing heat transfer sections sequentially installed in a duct, communicated through the air by overflow ducts and connected in a flow pattern to a supply duct with a heater installed in it, the heating line of which is connected and heat exchanger 2).
Недостаток известного воздухоподогревател заключаетс в низкой ступени защиты от коррозии теплообменных секций, что уменьшает экономичность его работы.A disadvantage of the known air preheater is the low degree of corrosion protection of the heat exchange sections, which reduces the efficiency of its operation.
Цель изобретени - повышение экономичности .The purpose of the invention is to increase efficiency.
Поставленна цель достигаетс тем, что теплообменник вод ного контура установлен в переточном коробе, соедин ющем две последние по ходу воздуха секции.The goal is achieved by the fact that the heat exchanger of the water circuit is installed in the overflow duct connecting the last two along the section air path.

На чертеже схематично изображен предлагаемый воздухоподогреватель.The drawing schematically shows the proposed heater.
Воздухоподогреватель содержит последовательно установленные в газоходе 1 теплообменные секции 2, сооб-15 щенные по воздуху переточными коробами 3 и подключенные через последнюю по ходу газа секцию по схеме противотока к подающему воздуховоду 4 с установленным в нем калорифером 5, The air heater contains heat exchanging sections 2 sequentially installed in the duct 1, communicating by air with overflow ducts 3 and connected through the last section along the gas flow in a countercurrent circuit to the supply duct 4 with the heater 5 installed in it,
20 греюща лини которого соединена с вод ным контуром 6, снабженным насосом 7 и теплообменником 8. Теплообменник 8 установлен в переточном коробе 3, соедин ющем две последние 25 по ходу воздуха секции 2.A heating line 20 of which is connected to a water circuit 6, equipped with a pump 7 and a heat exchanger 8. A heat exchanger 8 is installed in a transfer box 3 connecting the two last 25 along the air path of section 2.
Воздухоподогреватель работает следующим образом.The air heater works as follows.
Холодный воздух подают в воздуховод 4, где в калорифере 5 воздух 30 дредварительно подогреваетс водойThe cold air is supplied to the duct 4, where in the heater 5 the air 30 is pre-heated with water.
