Definitions

  • the present invention relates to a method in accordance with the preamble of claim 1.
  • the invention also relates to a gas appliance in accordance with the preamble of claim 4.
  • Such a method and gas appliance are known from document DE 100 01 251 A1 .
  • the gas is fed to the burner/burners via calibrated holes or orifices which, in combination with the value of the pressure at the outlet of the gas valve, define the correct gas flow rate corresponding to the appliance working power.
  • the calibrated hole or orifice is normally an independent component which is added to the gas feed line or directly to the burner, such that it can be replaced if the appliance is to be adapted to a different fuel gas type.
  • the need for the orifice or calibrated hole arises mainly because of the need to adapt the gas outlet pressures (from the burner feed lines) to the normal operating ranges of commercially available gas valves, because of the normal presence of a pressure regulation downstream of the cylinder in the case of LPG gas, because of the need to obtain correct gas-air mixing (by virtue of a predefined gas exit velocity from each individual orifice) and because of the impossibility of traditional systems to assess the respective situation.
  • An object of the present invention is to provide a method and an appliance in which this method is implemented, which represent improvements on corresponding known methods and appliances.
  • a particular object of the invention is to provide a method for controlling a gas appliance which enables this latter to be used with any type of gas, without it being necessary to "mechanically” modify or adapt said appliance (or boiler) to a particular gas or gas family.
  • Another object is to provide a method of the stated type by which the boiler can operate in accordance with optimal combustion parameters for every type of gas and enables combustion situations with parameters not accepted by regulations to be avoided, but always with parameters such as to achieve a non-pollutant combustion.
  • a further object is to provide a method of the stated type which enables the boiler to operate correctly and safely.
  • Another object is to provide a gas appliance or boiler in which the aforeindicated method is implemented and which has low production and installation costs.
  • FIG. 1 shows a simplified block diagram of some elements (useful for understanding the present invention) of a gas boiler or appliance formed in accordance with the invention.
  • the boiler comprises a burner 1 in proximity to which an electrode (or equivalent member) 2 is positioned to sense the flame level of the burner 1.
  • This sensing electrode or member 2 is associated with its own known electronic circuitry (not shown), and operates by generating an electrical signal corresponding to the combustion "quality", i.e. by sensing if it takes place without generating pollution and is within regulation limits.
  • the electrode 2 is connected to a preferably microprocessor unit 5 adapted to control the correct operation of the boiler. More specifically, this control by the unit 5 takes place via the flame signal (originating from the electrode) used as feedback for a control loop which also comprises an actuator 6 for a modulating valve 7 (i.e. for shut-off and/or turndown) for the gas flow towards the burner and positioned in a gas feed line 8 to the burner.
  • This feed line 8 is connected to one or more gas feed conduits (not shown) associated with the burner.
  • Each gas feed line is without orifices specifically arranged for a particular gas type with which the boiler can operate. If the burner is provided with a plurality of gas feed lines, all of them are not provided with specific gas orifices, but instead comprise a simple calibrated hole usable with any gas fed to the burner.
  • the method of the invention comprises activating a combustion control algorithm (block 11). This control is implemented, in known manner, on the basis of monitoring the flame via the electrode 2.
  • control can also be carried out in accordance with PCT application No. PCT/IT2010/000126 in the name of the same Applicant, according to which the control unit 5 cooperates with a memory unit (not shown) in which a plurality of optimum boiler working conditions are stored, conditions which are functions of characteristics related to the flame, to the thermal power and to the lambda value, and are represented on operating curves.
  • the boiler operating point is determined on one of these curves, the combustion air/gas ratio is modified starting from a current operating value, displacing this operating point along the curve, checking if that ratio variation arrives at a predefined value, and if this is the case then restoring a preceding air-gas ratio of correct operation, whereas if this is not the case the gas flow is modified to achieve an optimal combustion ratio.
  • the subsequent block 12 evaluates whether combustion has started and is within the parameters and is non-polluting or whether it is found to be outside these parameters.
  • the gas flow to the burner is increased by acting via the unit 5 on the valve 7 (block 13) to at most a predetermined maximum value, and the process then terminates (block 14).
  • the gas flow is decreased (block 15) and it evaluates whether a minimum flow value has been reached (block 16). If it is in this condition, possibly after a succession of flow modifications, the burner is halted (block 17), because a malfunction condition is sensed such as to make it opportune to block or halt the appliance to avoid potential damage or danger, and maintenance is requested. If it is not in this condition and the gas flow reduction by the actuator 6 of the valve 7 brings the boiler into an operating condition within accepted limits, the achieved situation is maintained as operation is taking place correctly. The procedure hence terminates (block 14).
  • the control unit 5 maintains the valve 7 in the attained position as long as the gas within the system or appliance remains at a flow rate such as to enable correct combustion with the passage of time.
  • the same boiler model or a defined power of a gas appliance can be used for all gas types, without the need to modify the orifices on the basis of the gas fed to the appliance.
  • the interchangeable orifices are totally replaced by substituting them with a simple calibrated hole on the gas feed side to obtain maximum cost advantage during boiler production.
  • an automatic combustion control system controlling the air/gas ratio
  • the presence of a different gas type during installation can be indicated by monitoring the gas valve control parameters or the flame signal dynamics, based on a definite working power or combustion value (greater or lesser gas valve opening to obtain the same combustion datum or greater or lesser flame signal dynamics for equal working conditions), so warning the installer of the need to modify the gas family configuration parameter.
