Description

Изобретение относитс  к области энергетики и может быть использовано дл  получени  пара. Известна топка, содержаща  жаровую трубу с расположенньпуги на входе горелкой, а на выходе - конфузором, снабженным завихрителем и подключенным центральным отверстием к камере дожигави  С ЗНедостатками известного устррйств  вл ютс  сложность конструкции и низ ка  эффективность сжигани  топлива. Цель изобретени  - повышение эффективности сжигани  и упрощение конструкции. Указанна  цель достигаетс  тем, что завихритель образован канавками выполненными в стенке конфузора со стороны, обращенной к полости жаровой трубы, и расположенными тангенциально к воображаемой окружности, вписанной в отверстие конфузора. Кроме того, канавки выполнены сужающимис  в направлении к отверстию конфуэора. На фиг. 1 изображена топка, продольный разрез; на фиг. 2 - завихри тель. Топка содержит жаровую трубу 1 с расположенными на входе горелкой 2, а на выходе - конфузором 3, снабженным завихрителем 4 и.подключенным центральным отверстием 5 к камере дожигани  6. Завихритель 4 образован канавками 7, расположенными тангенциально к воображаемой окружности 8. Камера дожигани  6 подклйчаетс  ДБГМОгарными трубка ли 9 к газоходу 10. Дл  отвода пара служат патрубки 11. Пунктирна  лини  12 показывает уровень воды. При работе топки топливо подаетс  в горелку и горит в жаровой трубе 1. Однако в результате охлаждени  через наружную стенку жаровой трубы 1, омываемую водой, топливо,сгорает в последней неполностью, а недогоревшее топливо через завихритель 4, образованный канавками 7, направл етс  в камеру дожигани  6, где и догорает. Продукты сгорани  проход т через дымогарные трубки 9 и удал ютс  в газоход 10. Образующийс  пар выходит в патрубки 11. Выполнение завихрител  в виде тангенциальных канавок с уменьшающимс  по ходу газа сечением позвол ет также существенно повысить эффек-. Нгивность сжигани  топлива.The invention relates to the field of energy and can be used to produce steam. The known furnace containing a flame tube is located at the inlet of the burner and at the outlet is a confuser equipped with a swirler and a central opening connected to the afterburner chamber. The disadvantages of the known devices are the design complexity and low efficiency of fuel combustion. The purpose of the invention is to increase the combustion efficiency and simplify the design. This goal is achieved by the fact that the swirler is formed by grooves made in the wall of the confuser from the side facing the cavity of the flame tube and arranged tangentially to an imaginary circle inscribed in the hole of the confuser. In addition, the grooves are made tapering towards the confueor opening. FIG. 1 shows a firebox, longitudinal section; in fig. 2 - swirl. The firebox contains a flame tube 1 with a burner 2 located at the inlet, and a confuser 3 equipped with a swirler 4 and connected by a central hole 5 to the afterburning chamber 6 at the outlet. The swirler 4 is formed by grooves 7 located tangentially to an imaginary circle 8. The afterburner 6 is connected DGMOgarny tube 9 to the flue 10. For the removal of steam are the pipes 11. The dotted line 12 shows the water level. During the operation of the furnace, fuel is supplied to the burner and burns in the flame tube 1. However, as a result of cooling, the outer wall of the flame tube 1, washed by water, is not fully burned in the latter, and the unburned fuel, through the swirler 4, formed by the grooves 7, is directed to the chamber afterburner 6, where it burns down. Combustion products pass through the smoke tubes 9 and are removed into the duct 10. The resulting steam enters the nozzles 11. Making the swirler in the form of tangential grooves with a cross-section decreasing along the gas flow also makes it possible to significantly increase the effect. Ngivnost burning fuel.
