摘要： A method and an apparatus for determining the calorific value parameter describing the calorific value of a gaseous fuel. The apparatus comprises a test burner with a test combustion chamber. An air ratio sensor is arranged in an exhaust gas duct of the test burner and measures an air ratio signal that corresponds to the air ratio of the exhaust gas. As a function of the received air ratio signal, at least one setting signal is generated for a test supply unit via a test control unit. The setting signal controls the amount and/or the proportion of a gaseous fuel or an oxygen-containing gas that is supplied to the test combustion chamber. A calorific value sensor arrangement is provided in the combustion chamber and has an ionization sensor and, a temperature sensor. The sensor signal of the calorific value sensor is transmitted to a determination unit.

摘要： Provided is a method for operating a non-condensing boiler at maximum non-condensation efficiency, and more particularly a method for operating a non-condensing boiler, capable of supplying an appropriate amount of excess air for combustion of a burner, avoiding damaging a heat exchanger due to the condensed water generated at the heat exchanger, and effectively improving the heat efficiency. The method comprises the steps of: sensing a temperature of exchange water introduced into a heat exchanger and a temperature of supply water discharged from the heat exchanger and calculating an average temperature from the two temperatures to obtain a maximum concentration of CO using information stored in a controller; calculating a ratio of excess air (λ) from the maximum concentration of CO using a combustion equation chosen depending on a fuel used; checking from a combustion characteristic curve whether or not the excess air ratio (λ) is within a stable combustion region; when the excess air ratio (λ) is within the stable combustion region, setting this excess air ratio to the control target value, and when the excess air ratio (λ) is less than a lower limit of the stable combustion region, setting a minimum excess air ratio of the stable combustion region to the control target value; calculating a target value of air flow suitable for the current consumption amount of fuel based on the set excess air ratio; and performing feedback control with respect to the air flow target value and a value input from an air flow sensor. With this configuration, no condensation takes place during operation of the non-condensing boiler, so that the boiler can have increased durability, be easily assembled at inexpensive production costs, be made compact, and obtain maximum heat efficiency under a non-condensation condition.

摘要： A method for maximizing the power in regard to the fuel quality when burning solid fuels, especially biomass and peat. The maximizing of the power is performed within the limits for the plants maximum permitted power production, and at the same time with regard to the maximum achievable power with the fuel quality in use. The maximizing of the power with regard to the fuel may either be controlled by the temperature changes in the fuel gas emerging from the fuel bed or by the fuel moisture content with regard to the fuel actually processed in the gasifier. The maximum allowable gasification air flow in regard to the fuel quality can either be theoretically or empirically evaluated.

摘要： A sensor for determining an air ratio of a fuel gas/air mixture, wherein a housing is formed, which delimitates a measuring space. The housing has on one side a diffusion passage for coupling with a fuel gas/air mixture flow, wherein the diffusion passage is formed by a gas-permeable separating agent. An electrically operated excitation element is arranged for energy supply into the measuring space in order to induce a chemical reaction of a fuel gas/air mixture in the measuring space. At least one optical detection device is directed into the measuring space with its detection area, wherein the at least one optical detection device detects the intensity of radiation from the reaction position in at least a first wavelength range and produces a signal being allocated to the detected intensity, from which the air ratio is inferable.

摘要： A grounded burner, actuators adjusting the supply of fuel and air to the burner, an ionization electrode in the flame region, a flame amplifier at the ionization electrode generating an ionization signal, and a final control device are included in a burner system. During air ratio control mode, the final control device sets a first actuator and adjusts a second actuator. During voltage control mode a voltage regulator controls the AC voltage source using the AC voltage measured by the voltmeter, in conjunction with an ionization current amplifier. The voltmeter is connected in parallel with a sequence of the ionization electrode, the flame region, the burner and the input of the ionization current amplifier. The voltage regulator is connected to the voltmeter such that, during voltage control mode, the time-averaged current caused by the voltmeter through the connection is less than 5% of the time-averaged current through the ionization electrode.
