Equipment for regulating a combustion device includes two laminar flow resistors and an air pipe incorporating a fan with changeable RPMs to feed into a mixer.

摘要

An air pipe (1) incorporates a fan (2) with changeable RPMs that feeds into a mixer (4) and a first laminar flow resistor (5). A gas pipe (6) linked to the mixer contains a regulator (7) and a second laminar flow resistor (9). The regulator operates through pressure in the air pipe upstream from the first laminar flow resistor.
