The hanging stove in this embodiment includes: a burner; the combustion chamber corresponds to the combustor and is used for supplying gas for combustion; the flame detection needle is arranged in the combustion chamber and is used for detecting flame in the combustion chamber; wherein, examine the controller electricity in fire needle and the hanging stove and be connected, and move along a movement track in the combustion chamber, with the flame to different positions in the combustion chamber detects, and then adopt the hanging stove in this embodiment, when the flame burning condition in the hanging stove is examined to needs, the flame condition of obtaining different positions in the combustion chamber that the needle of examining of a movement track motion can be convenient in the combustion chamber, and then can acquire the different burning condition in the combustion chamber, examine more comprehensive of fire mode, the precision of examining fire has been promoted.
Specifically, the fire detection needle in the embodiment is movably installed on the combustor, the wall-mounted furnace further comprises a driving device for driving the fire detection needle, the fire detection needle moves along the track under the driving of the driving device, the fire detection needle moves relative to the combustor through the driving of the driving device, and the detection precision is higher under the condition of flames at different positions.
The physical fire detection needle is driven by the driving device to swing back and forth along the motion track.
The specific motion track is an arc track, and the fire detection needle reciprocates along the arc track.
Specifically, the driving device comprises a driving connecting rod and a driving motor, wherein one end of the driving connecting rod is matched with the fire detection needle, the other end of the driving connecting rod is hinged with the combustor, the driving motor is in transmission fit with the driving connecting rod, and the driving connecting rod in transmission fit with the driving motor swings in a reciprocating mode under the driving of the driving motor, so that the fire detection needle swings along the motion track.
As shown in fig. 2, the flame detection needle preferably moves in a range along the oblique cutting plane of the combustion chamber, so that the horizontal displacement and the height displacement of the flame detection needle relative to the combustor are different at any two positions, the flame can be detected at the horizontal position and the height position of the flame, and the detection precision is better.
Preferably, the included angle between the inclined plane of the motion track and the horizontal plane of the combustion chamber is 35-55 degrees, and the detection range is better comprehensive.
Preferably, the included angle between the inclined plane of the motion track and the horizontal plane of the combustion chamber is 45 degrees.
As shown in fig. 1, the embodiment provides a fire detection method for a wall-hanging stove, which obtains detection signals of the fire detection needle at different working positions; if the fire detection needle detects flame at a position far away from the burner, the flame is determined to have a flame-leaving risk; if the flame is not detected at the normal position away from the combustor by the fire detection needle, the flame is determined to have tempering air.
The embodiment also provides a fire detection method for the wall-hanging stove, which uses the wall-hanging stove, and comprises the following steps: acquiring detection signals of the fire detection needle at different working positions; by using the wall-mounted furnace fire detection method, more flame states can be obtained at different positions of the fire detection needle, and the fire detection precision is better.
By using the wall-mounted furnace fire detection method, more flame states can be obtained at different positions of the fire detection needle, and the fire detection precision is better.
The above detection method is exemplified below with reference to the following table. When the ion current is detected to be smaller than the normal combustion parameter. For example, the set firing current is set to 0.2 microampere, and is actually 0.15 microampere. This means that the combustion intensity is low, the flame ion concentration is low, and the combustion does not reach the normal combustion condition. And adjusting the duty ratio, increasing the rotating speed of the fan, and readjusting the opening degree of the valve by the unit. Until the ignition current reaches 0.2 or is greater than the set value. In this travel trajectory, no flame is detected at a normal distance from the burner position, meaning that the gas flow rate < the combustion speed, and most likely a flashback. Detection of a flame at a location remote from the burner means that the gas flow rate > combustion speed, and is most likely to be away from the flame.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious variations or modifications therefrom are within the scope of the invention.
