These seem to be a very common style of component on Aliexpress and sometimes on eBay too.
It's a spark ignitor for gas that could be used for cooker, ovens or other applications. Unlike oil igniters or larger scale gas units, it doesn't have a continuous hot spark, but just pulses low current sparks continuously until the gas/air ratio hits the sweet spot and ignition occurs.
The design is gloriously simple due to the use of a specialist component designed almost exclusively for generating high current pulses used to drive the transformer assembly.
The format of these varies. This one appears to have three separate high voltage secondaries, which raises the intriguing possibility of wiring them in series for a single higher voltage spark.
Other versions have a common ground connection and several outputs referenced to that.
If desired, the PCB could be removed for driving your own custom transformer or pulse coil. Or alternatively you could take inspiration from its design for your own PCB design. It's a classic circuit.
The very high value resistor is a discharge resistor designed to gently discharge the main capacitor to prevent a rogue unexpected spark due to retained charge, or possibly to avoid false triggering due to leakage current on the supply circuit causing the capacitor to gradually charge up until a spark occurs unexpectedly.

coils in series for a bigger bang?
You mentioned SIDACs in a previous "deconstruction" video – and they are useful for the purpose shown – dumping a large charge from a cap in series with an inductor. I've seen these being used in other applications (particularly mains bug zappers, where the HV output is used to charge a cap. bank for an "extra juicy" spark when an "undesireable" bridges the (usually wire mesh) contacts!
This is what I kept yelling though this entire video: GET TO THE POINT.
2.88w, but only half wave, so 1.44w of dissipation, spread over 2 resistors, would approximate 700mw each… so probably the resistors current rating is being abided by. Even if other parts here aren't as per other commentors.
This is the best channel about electronics 😉
Ways to overclock it:
1- full bridge rectifier
2- bigger capacitor
3- higher frequency power suply
It sort of resembles a Thomas the train look doesn't it?
Oh it's 2:40 in the morning, I'm watching big Clive again!
BigClive vapes? Chuffa-chuffa-chuffa…
😁
nice how do comments say 3 weeks ago (patreon i saw)
So Clive got bored and dismantled his cooker..maybe next week when Clive stays at a local hotel we'll get a reverse engineered "Corby trouser press" 😁
Cool video. 👍
Watched your last night show and i'm here again – Addiction? 😁
Yessiree Bob ❤️✌️
