Description
Предметом кзсбретени вл етс воздухоподогреватель дл паровозного котла, отличительна особенность которого состоит в том, что передача тепла от уход щих газов к воздухоподогревателю производитС при помощи пара, производимого в парогенераторе, размещенном в дымовой коробке.The subject of an exclusion is an air preheater for a locomotive boiler, the distinguishing feature of which is that heat transfer from the flue gases to the air preheater is carried out with steam produced in a steam generator located in a smoke box.
На чертеже приведена принципиальна схема описываемого ниже воздухоподогревател .The drawing is a schematic diagram of the air heater described below.
Воздухоподогреватель 1 (ребристый ) размещаетс недалеко от зольника. По трубе 2 к нему подводитс смесь пара и гор чей воды из парогенератора 3, расположенного в дымовой коробке и выполн ющего одновременно роль искрогасител . Из воздухоподогревател 1 охлажденна вода по трубе 4 циркул ционным насосом 5 вновь подаетс в парогенератор 3При размещении воздухоподогревател 1 выще парогенератора 3 циркул ционный насос 5 может отсутствовать .Air heater 1 (ribbed) is located near the ashpit. The pipe 2 supplies the mixture of steam and hot water from the steam generator 3, located in the smoke box and simultaneously playing the role of a spark arrester. From the air preheater 1, the cooled water through the pipe 4 by the circulation pump 5 is again supplied to the steam generator 3. When the air preheater is placed 1 above the steam generator 3, the circulation pump 5 may be absent.
Давление нара и воды в системе (батаре воздухоподогревател 1, змеевик парогенератора 3 и трубы 4 и 2) автоматически поддерживаетс в пределах 10-12 ат. Увеличение этого давлени нецелесообразно, такThe pressure of the pump and the water in the system (the battery of the air heater 1, the coil of the steam generator 3 and the pipes 4 and 2) are automatically maintained within 10-12 at. An increase in this pressure is impractical, so
как оно приводит к уменьшению перепада температуры от газов к воде, наход щейс в парогенерато )ре.as it leads to a decrease in the temperature difference from gases to water in the steam generating unit.
Подогретый в воздухоподогревателе / воздух пароструйным насосом 6 нагнетаетс в закрытый зольник . Дл работы пароструйного насоса 6 может быть использован пар, получаемый выпариванием продуваемой воды или же отработанный пар от машины паровоза (в момент малых нагрузок котла).Heated in the air preheater / air with a steam jet pump 6 is injected into a closed ash pan. For the operation of the steam jet pump 6, steam obtained by evaporating blown water or the exhaust steam from a steam engine machine (at the moment of low boiler loads) can be used.
В зольнике создаетс давление больше атмосферного на величину, примерно равную сопротивлению сло топлива на колосниковой решетке .In the ash pan, a pressure is created greater than atmospheric by an amount approximately equal to the resistance of the fuel layer on the grate.
Вода между воздухоподогревателем / и парогенератором 3 циркулирует в замкнутом контуре, что исключает возможность загр знени теплонередающих поверхностей системы накипью.The water between the air heater / and the steam generator 3 circulates in a closed circuit, which eliminates the possibility of contamination of the heat transfer surfaces of the system with scale.
