DISPOSITIVO PE REGOLARE L'ALIMENTAZIONE DI UN GAS E PER REGOLARE UNA PRESSIONE DI LAVORO AD UN DISPOSITIVO DI COTTURA A GAS CON BRU- |
摘要 |
<p>The invention is directed to an arrangement for adjusting a pressure-fluctuation free supply of gas and for controlling an operating pressure of an air/gas mixture to a radiation-gas burner of a gas cooking apparatus. The radiation-gas burner has a burner chamber and is mounted in a housing below a cover plate. The arrangement includes a gas supply conduit connectable to a gas source for receiving the gas and a pressure controller is mounted in the gas supply conduit for controlling the pressure of the gas to a constant operating pressure of at least 2.5 mbar above atmospheric pressure. A control unit is connected to the pressure controller for receiving the pressure-controlled gas and for metering the gas to the radiation-gas burner. The control unit includes a valve block having at least one exchangeable nozzle adapted to the type of gas from the gas source and a feed conduit has a clear cross-sectional area and communicates with the burner chamber. The feed conduit has an inlet opening adjacent the nozzle. A blower blows air into the apparatus to generate an overpressure whereby the gas metered by the control unit through the nozzle entrains air to form an air/gas mixture entering the feed conduit. An insert is mounted in the feed conduit for reducing the cross-sectional area of the feed conduit. The insert is selected so as to reduce the cross-sectional area to enable the radiation-gas burner to operate at a predetermined efficiency irrespective of the fluctuations in the pressure of the gas and the changes in type of the gas.</p> |
