Conversion furnace temperature control system that enters mouth

The utility model provides a conversion furnace temperature control system that enters mouth, including cold by -pass and the bypass temperature control pipe way (7) that is used for adjusting the self -modulation valve control of conversion furnace inlet temperature, follow water gas is drawn forth to medium temperature converter pipeline (1) bypass temperature control pipe way (7), the other end of bypass temperature control pipe way (7) with conversion furnace entry pipeline (3) intercommunication, adjusting valve (7.1) are installed to bypass temperature control pipe way (7). The advantage does: (1 )The inside catalyst of control change stove does not have super temperature phenomenon and takes place at the application temperature at the initial stage of driving, has prolonged catalyst life, and economic benefits is fairly obvious. (2 )Have to original device reform transform less, the disinvestment, but reach the advantage of actual effect. 本实用新型提供种变换炉入口温度调节系统，包括用于调节变换炉入口温度的自调阀控制的冷副线以及旁路温控管道(7)；从所述水煤气向中温
