Abstract
A method is proposed for regulating a firing device taking into account the temperature and/or the burner load, in particular with a gas burner, comprising the regulation of the temperature (Tactual) produced by the firing device using a characteristic which shows a value range corresponding to a desired temperature (Tdesired) dependent upon a first parameter (mL,VL) corresponding to the burner load (Q), wherein when representing the characteristic, a second parameter, preferably the air ration (λ), defined as the ratio of the actually supplied quantity of air to the quantity of air theoretically required for optimal stoichiometric combustion, is constant.
Claims11
A method for controlling a firing device, in particular a gas burner, wherein
- when a parameter which corresponds to the burner load is changed from a start value to a target value, the supply of fuel to the firing device is adapted by a change to the opening of the gas valve from a first to a second opening value specifying a desired value which is dependent upon the parameter, the second opening value lying between an upper and a lower limit value, and during the transition of the opening of the gas valve from the first to the second opening value, no regulation of the supply of fuel being implemented, and after the target value of the parameter, which corresponds to the burner load, has been reached, regulation of the operating parameters of the firing device being implemented.
A firing device, in particular a gas burner, comprising:
- a gas valve for setting the supply of fuel to the firing device;
- a storage unit for storing desired values which are dependent upon a parameter which corresponds to the burner load and upon upper and lower limit values:
- a device for controlling the opening of the gas valve which, when a parameter, which corresponds to the burner load, is changed from a start value to a target value, adapts the opening of the gas valve from a first to a second opening value according to a stored desired value, the second opening value lying between a stored upper and a lower limit value, and during the transition of the opening of the gas valve from the first to the second opening value no regulation of the fuel supply being implemented;
- and
- regulating means which, after reaching the target value of the parameter, which corresponds to the burner load, regulate the operating parameters of the firing device.
