DETAILED DESCRIPTION

[0016] The following is only a preferred embodiment of the present invention, and the protection scope is not limited to this embodiment. All technical solutions under the concept of the present invention should belong to the protection scope of the present invention. At the same time, it should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.

[0017] See Figures 1 to 3 As shown, a burner controller that is easy to disassemble and assemble comprises a housing 1 and a housing cover 2 hinged on one side of the housing 1, wherein a control module 12 is screwed in the housing 1, and the control module 12 comprises at least a PLC controller, an electronic ignition module, a flame monitoring module, a two-stage power switching module, a valve driving module, a storage module and a communication module;

[0018] Specifically, the PLC controller coordinates and controls the flame monitoring module, the two-stage power switching module, the valve drive module, etc. to realize intelligent control of the burner. The storage module is used to record the data of combustion and flame detection. The communication module is used to connect with the control terminal signal in real time to realize remote control.
