1. The feeding system for low-pressure lighting-up oil burners is designed especially for dynamic gas burners in coal boilers. At the input, the system has a self-operating pressure-reducing valve, by-passed with a cut-off valve. At the output, it has a damping element located between two valves and equipped with a by-pass with a cut-off valve. Characterized in that: the by-pass of the self-operating pressure-reducing valve (6) is equipped with an automatically-controlled cut-off valve (7), while it has a non-return valve (8) at its output (3). |
