Description

Известны способы защиты рекзператоров промышленных печей от воздействи  газов высоких температур путем использовани  предвключенных поверхностных теплообменников, размещаемых в газоходах печей дл  снижени  температуры газов- Однако такие способы недостаточно экономичны.Methods are known for protecting industrial furnaces from exposure to high temperature gases by using upstream surface heat exchangers placed in furnace gas ducts to reduce the temperature of gases. However, such methods are not economical enough.

В описываемом способе дл  повышени  экономичности и производительности печей теплообменник включают в контур с принудительной циркул цией воды в системах теплопотребителей, которую направл ют на вход в теплообменник через дроссельную шайбу дл  обеспечени  т;осто нного сопротивлени  теплообменника при любых колебани х тепловых нагрузок.In the described method, in order to improve the efficiency and productivity of the furnaces, the heat exchanger is included in a circuit with forced circulation of water in the systems of heat consumers, which are directed to the heat exchanger through the throttle washer to ensure heat resistance of the heat exchanger during any fluctuations in thermal loads.

На фиг. I изображена схема включени  теплообменника; на фиг. 2 - установка дроссельной шайбы во входной камере теплообменпика .FIG. I shows the heat exchanger switching circuit; in fig. 2 - installation of the throttle washer in the inlet chamber of the heat exchanger.

Способ защиты рекуператоров промышленных печей состоит в том, что непосредственно в газоходе / между печью 2 и рекуператором 3 включают теплообменник 4. В теплообменник 4 насосами 5 по трубопроводу 6 подают воду, а паровод ную смесь по трубопроводу 7 направл ют в котел-утилизатор 8. После отделени  пара от воды последнюю снова направл ют в циркул ционную систему, а пар через перегреватель 9 Котла 5 отвод т и подают дл  технологических и нужд. С помощью дроссельной шайбы 10, установленной во входной камере // производ т автоматическое регулирование температуры газэв перед рекуператором 3. Кроме дроссельной щайбы 10, на входе теплообменника устанавливают также фильтр 12.The method of protecting recuperators of industrial furnaces is that directly in the gas duct / between the furnace 2 and the heat exchanger 3 a heat exchanger 4 is turned on. Water 5 is supplied to the heat exchanger 4 by means of the pipeline 6, and the steam-water mixture is sent through the pipeline 7 to the heat exchanger 4. After the steam is separated from the water, the latter is again sent to the circulating system, and the steam through the superheater 9 of the Boiler 5 is removed and supplied for process and needs. Using the throttle washer 10 installed in the inlet chamber //, the temperature of the gasev before the heat exchanger 3 is automatically controlled. In addition to the throttle plate 10, a filter 12 is also installed at the inlet of the heat exchanger.

Описываемый способ позвол ет исключить необходимость в подаче воздуха дл  разбавлени  газового потока, поступающего к рекуператору , сократить размеры элементов газового тракта (рекуператоров, боровов, дымовой трубы, дымососа), задерживать окалину застревающую Б сетке труб теплообменника, что вследствие ее гранулировани The described method eliminates the need for air supply to dilute the gas flow to the heat exchanger, reduce the size of the gas duct elements (heat exchangers, hogs, chimney, smoke exhauster), delay the scale of the sticking heat exchanger pipe B, which is due to its granulation

резко уменьшает загр зн емость рекуператоров и повышает выход гор чего воздуха, и утилизировать тепло.dramatically reduces the pollution of recuperators and increases the yield of hot air, and recycle heat.

Испытани , проведенные в трубосварочном цехе Чел бинского трубопрокатного завода, подтвердили промышленную полезность описываемого способа.Tests carried out in the pipe-welding shop of the Chel Beansky Pipe-Rolling Plant confirmed the industrial usefulness of the described method.

Предмет изобретени Subject invention

Способ зашиты ре куп ер атворов промышленных печей от воздействи  газов высоких температур путем использовани  предвключенных поверхностных теплообменников, размешаемых в газоходах печей, дл  снижени  температуры газов, отличающийс  тем, что, с целью повышени  экономичности и производительности печей, включают теплообменник в контур с принудительной циркул цией воды или другой жидкости в системах теплопотребителей, которую направл ют на вход в теплообменник через дроссельную шайбу дл  обеспечени  посто нного сопротивлени  теплообменника при любых колебани х тепловых нагрузок.The method is sewn up by the reverser of industrial furnaces from high-temperature gases by using upstream surface heat exchangers stirred in the furnace gas ducts to reduce the temperature of the gases, characterized in that, in order to improve the efficiency and productivity of the furnaces, the heat exchanger is incorporated into a circuit with forced circulation water or other liquid in the systems of heat consumers, which is directed to the entrance to the heat exchanger through the throttle washer to provide constant resistance to heat bmennika with any fluctuations in thermal loads.
