Atmospheric gas burner has free flow cross-section in mixer tube formed by deformable element acted upon by variable pressure medium and varied by concentrically altering pressure

摘要

The gas burner has at least one gas nozzle (1) connected to a gas line (2) and directed against a mixer tube (3), whereby primary air is sucked up by the gas pulse and the gas-air mixture thus produced is fed via the free flow cross-section (5) of the mixer tube to a burner body (4). The free flow cross-section is formed by a deformable element (6) acted upon by a medium under a variable pressure and can be varied by concentrically altering the acting pressure An Independent claim is also included for a method of controlling or regulating the primary air flow for an atmospheric gas burner.
