The utility model discloses a control valve driving device, a flame control system and a gas furnace, the control valve driving device comprises a control module, a temperature detection module, a valve driving module and a power supply module, and the valve driving module comprises a first interface and a driving circuit. The control module compares the temperature collected by the temperature detection module with the set temperature so as to calculate a pulse width control signal needing to be output, and the pulse width control signal provides corresponding driving current through the valve driving module so as to achieve the effect of linearly controlling the switching value of the proportional control valve. And therefore, the air inlet amount and the flame size are finely adjusted so as to more accurately control the temperature of the gas furnace. 本实用新型公开一种控制阀驱动装置、火焰控制系统及气炉，包括控制模块、温度检测模块、阀门驱动模块及电源模块，阀门驱动模块包括第一接口及驱动电路。控制模块将温度检测模块采集的温度与设定温度进行比较，以计算需要输出的脉宽控制信号，脉宽控制信号经阀门驱动模块提供对应的驱动电流，以实现线性控制比例控制阀开关量的效果，从而
