Which boiler chimneys require online monitoring?

Which chimneys require online flue gas monitoring? Do gas boilers need online monitoring or sampling ports?
It has nothing to do with the type of fuel, right? It should be related to the output or thermal power. Personal opinion.
It is necessary to install online monitoring or sampling points at the emission outlet; if there is exhaust gas treatment, such points should be placed at the emission outlet at the rear end of the exhaust gas treatment equipment.
Standards do require the establishment of monitoring points, but currently the environmental protection agency focuses on coal-fired boilers; there are no mandatory requirements for gas-fired ones.
Standards vary from place to place; there is currently no mandatory requirement for gas, while installation for coal is required
Typically, boilers with a capacity of 20 t/h or 14 MW and above require the installation of online flue gas monitoring systems
Under which standard can it be found?
May I ask in which specification this can be found?
