Abstract (en)
[origin: EP2287531A2] The method involves premixing air and combustion gas, and adjusting outlet pressure (Pout) of the combustion gas equal to a reference pressure (Pref) before admission into a mixing space of a gas valve in two stages by a zero-pressure control valve (5) that is provided with servo pressure regulator valve unit (5a). Input side pressure (Pi) of combustion gas is reduced in one of the stages to a reference pressure (Pref) and a predetermined pressure portion (Px). The pressure is reduced to reference pressure constantly around the pressure portion in another stage. An independent claim is also included for a combustion system with a combustion gas-air-mixing device.
