Ignition circuit

Номер: CN116026199A

Автор: AO XIAOQIANG, ZENG MING, SUN ZHE, WANG XIAOFEI

Принадлежит:

The invention relates to an ignition circuit. The ignition circuit comprises a synchronous step-down control circuit used for outputting an output voltage from an output end of the synchronous step-down control circuit; the electric heating wire is provided with a first end and a second end which are connected with the output voltage; and the feedback circuit is connected between the second end of the electric heating wire and the feedback end of the synchronous step-down control circuit and is used for feeding back the synchronous step-down control circuit based on the output current of the synchronous step-down control circuit. Therefore, by adopting a synchronous voltage reduction mode to be matched with current feedback, the ignition operation can be realized through constant-current and constant-voltage control, so that the influence of the resistance change of the heating wire on the ignition function can be effectively reduced, and the ignition reliability is improved.

A high-temperature sampling probe and high-temperature gas analysis system

Номер: CN0101551306A

Автор: AO XIAOQIANG, CHEN HUASHEN, XIAOQIANG AO, HUASHEN CHEN

Принадлежит:

The embodiment of the present invention provides a high-temperature sampling probe and high-temperature gas analysis system. The high-temperature sampling probe is used to sample the gas in the pipeline. This probe may include: The installation tube accessible to the pipeline, and the probe tube that is inserted into the installation tube and of which end sticks into the pipeline. The probe tube and the installation tube are fixed with a flange and made from material that resists high temperature. The high-temperature sampling probe provided by the embodiment of the present invention doesn't need a cooling chamber. The probe not only has a simple structure but also no longer needs other extra auxiliary cooling devices. Moreover, as the structure is relatively simple, the failure rate is very low and no moving device that move in and out the probe is needed. This saves cost. The cost of the high-temperature gas analysis system with this high-temperature sampling probe is reduced due to the ...
