The invention relates to a method for evaluating a quasi-steady-state pressure difference in a gas-fired boiler which can be obtained by a sensor, the sensor being a differential pressure sensor or a mass flow sensor, the gas-fired boiler having a mixing device (4), a blower (5), a main flow limiter (3), a regulating valve (2) and a safety valve (1), the mixing device is used for mixing fuel flowing in from a fuel inlet (G) and air flowing in from an air inlet (L) to form a fuel-air mixture, the air blower is used for sucking the fuel and the air passing through the mixing device, and the main flow limiter (3) is used for limiting the mass flow of the fuel in the mixing device (4). The regulating valve (2) is arranged upstream of the main flow limiter (3) and is used for regulating the mass flow of the fuel entering the mixing device (4), and the safety valve (2) is arranged upstream of the regulating valve (2) and is used for interrupting the mass flow of the fuel; wherein the sensor detects a pressure diffe
