Gas heat generator with gas/air mixture regulation has gas from gas fitting and air sucked in via small cross-section laminar flow elements with many throughflow channels

摘要

The device has a regulated gas fitting (GA), an air feed and a fan (B) that sucks in the gas (G) and air (L) and feeds them to a burner as a fuel mixture. Gas from the fitting and air are sucked in via laminar flow elements (LFEg,LFEl) with many channels of small cross-section that receive the gas and air at approximately equal pressures and end in a common plane in the fan's suction chamber (ASR. The fan works with a predeterminable vacuum
