Definitions
- the invention has for its object to provide a generic device with which the combustion air flow rate can be changed proportional to the fuel gas flow rate, in such a way that the air ratio is kept sufficiently constant under all operating conditions.
- a force acts on the setting element 4 which results from the combustion air stream 1.
- a fuel gas pressure adjusting device 8 is provided according to the invention. This is connected to the line 6 for supplying the fuel gas stream 7 in front of the gas nozzle.
- An actuator 9 is connected to the fuel gas pressure adjusting device 8, the arrangement and design always being such that the adjusting element 4 is adjusted with sufficient accuracy to the predetermined air ratio via this actuator 9. This is first explained in more detail below with reference to FIGS. 1 and 2.
- the control membrane 13 is located in a manometer housing 14. Its top side is pressurized with the pressure of the fuel gas stream 7 in front of the gas nozzle and its underside with the combustion air pressure, which is essentially determined by the chimney draft.
- the slip gap 15 is necessary for the smooth movement of the swing flap 4; it is kept as small as possible to avoid a significant influence on the air flow.
- the effective areas F L and F G and the lever arms r G and r L are to be coordinated with one another in such a way that the swing flap 4 adjusts itself to the “fully open” position when the device is subjected to maximum heat and the smallest possible chimney draft.
- FIG 3 the combustion chamber 3 of a space heater with direct chimney connection (without flow protection) is shown schematically, to which the combustion air stream 1 is fed through a controlled pendulum flap 4, on the one hand through an unchangeable passage opening 11 of the pendulum flap 4 and on the other hand by one of the Pendulum flap 4 and a stop ring 16 formed variable flow cross-section 5, the size of which depends on the position of the pendulum flap 4.
- the position of the pendulum flap 4 is determined by the differential pressure acting on it between the outside air pressure and the air pressure in the room, which is enclosed by the pendulum flap 4 and the walls of the air supply and the combustion chamber 3, and by the one hand with the gas pressure in front of the gas nozzle of the Fuel gas consumer 2, on the other hand controlled with the aid of the air supply tube also serving as actuator 4 with the pressure in the combustion chamber 3, which is essentially determined by the chimney draft, controlled control membrane 13.
- This pressure also acts on a compensating membrane 17, which on the other hand is acted upon by the chimney suction.
- This arrangement of the membranes 13, 17, 22 compensates for the differential pressure at the setting member 4 between the pressure after the heat exchanger 23 and the chimney suction and the actuator 9, which influences the free flow cross section 5 in the flow path of the exhaust gases 21 with the setting element 4, from the pressure difference on Heat exchanger 23 and the differential pressure ⁇ P ⁇ controlled.
- the actuator 9 consists of an actuator rod on which the diaphragms 13, 17, 22 on the one hand and the adjusting element 4 on the other hand are fastened.
- the heat exchanger 23 (in the event of a change in heat load) acts in a similar way to a flow resistance with turbulent flow characteristics in the cold combustion air stream 1.
- the above-mentioned adjustment of the flow characteristics can take place by appropriately designing the gas outlet opening (for example in the form of a slot nozzle).
