Combustion air metering system for burners - has axially arranged components and thermostatic control system

摘要

A control device for use in the air metering of combustion air for input fuel-air mixtures, is constructed such that the individual component sections are attached in a uniaxial manner in sequence one after the other. The sections have 100 deg. of radial motion capability around the axis. A series of e.g. thermostatic controls are provided by means of which a simple on-off process, or a two stage sliding side high-low system may operate for the air metering devices. Alternatively a two stage off-low-high process may be operated to permit burner control.
