What is the relationship between the number of quick-opening dampers, burners, and nozzles in a heating furnace?

For example, is the number of quick-opening dampers equal to the number of burners? Does a burner have multiple nozzles? That’s very unintelligent. Thanks
The number of burners’ nozzles can be many, depending mainly on the operating conditions. The principle relating the number of dampers to be opened to the amount of combustion is as follows: First, consider the design principles to determine whether full-load operation can be achieved under natural ventilation conditions. 2 If the previous principle is applied, the suction force can overcome the pressure drop from the quick-open damper to the end of the burner. 3 Generally speaking, the total opening size of the quick-opening damper only needs to be roughly equal to the total opening area of the burner. The numbers are not the same.
