Definitions
- the present invention relates to a heating device with gas burners.
- Gas burners are widely used today, especially for air heating, especially in livestock buildings. Disadvantage major of these burners lies in their reduced power range. Indeed, their operation, based on the ignition of an air / gas mixture, requires a compliance with the proportions of the components in the mixture. It is therefore impossible to vary significantly the amount of gas in the mixing without risking extinguishing the flame. Therefore, the trend today is to use powerful burners which are frequently switched between on and off positions for temperature regulation. It results from user comfort problems due to the inertia of its burners.
- a heating device To be able to cover a large power range without having to have powerful burners, a heating device has been devised several gas burners of the same power.
- the burners are divided into a burner, called a master, equipped with a device of ignition of air / gas mixture and in burners, called slaves, free of such device.
- the transition from one power stage to another is carried out by ignition of the burner immediately adjacent to the burner previously lit. This results in the obligation to carry out the lighting of said burners in an order predetermined according to the relative positioning of the burners on the pipe common gas supply.
- this solution may cover a large power range, the number of power stages is reduced and the stages between power stages are of constant value. This is due to fact that the gas burners used are all of the same power and that only ignition of a burner, immediately adjacent to a previously burner on, can be considered. Burner combinations are therefore limited.
- An object of the present invention is to overcome the aforementioned drawbacks by offering a heating device whose design allows variation power over a wide range, the value of the steps between stages of power can be freely chosen by the user so as to offer a great number of possibilities to the latter.
- Another object of the present invention is to provide a heating device whose number of burners, although reduced, allows a variation of power within a wide range while ensuring operation optimal and perfectly safe flame control device.
- Another object of the present invention is to provide a heating device simple in design and the number of parts can be reduced without affecting the safety of the whole.
- Another object of the present invention is to provide a heating device having a large number of power stages for a given number of burners, each power stage corresponding to a combination predetermined burners arranged in any manner in the device.
- the invention relates to a heating device of the type constituted at least three burners, respectively connected to a common line gas supply, itself connected to a gas supply source, each burner can be independently supplied with gas by via a lockable link with controlled opening / closing between the gas supply source and the burner, the burners being at least two types differing in their heating power, these burners being associated according to different selectable combinations corresponding each with a power stage, the control means opening / closing of the link of each controlling burner, when transition from a power stage N to a selected power stage P, the opening of the link of the burner (s) to light on the power stage P selected and at least the opening of the connections of all the burners separating a burner lit on the power stage N from a burner to be lit at the power stage P to allow automatic ignition of the flame of each burner by contact with the air / gas mixture expelled from said burner with the flame of an adjacent burner until the burner ignites at stage P selected then selective closing of burner connections not included in the combination corresponding to the power stage P selected,
- the device flame control can be common to all burners and activated by any of the burners due to the fact that when passing through a stage of power to another, all burners work.
- a release of sufficient heat to guarantee continued operation of the flame control in the case of a device operating by infrared either the temperature rise of the probe in the case of a control device of the flame operating by ionization.
- This ignition of all burners during the transitional period thus makes it possible to pass from a stage of power to another without having any common burner lit between the two stages thus increasing the number of combinations and as a result of power possible.
- the heating device is consisting of burners 1 connected to a rigid gas supply pipe 2, generally metallic, itself connected to a power source 3 gas which can be any.
- the whole forms what one could call a gas burner burner 1.
- the burners 1 act conventionally by combustion of an air / gas mixture.
- These burners 1 can be of the type atmospheric or dynamic. In such a device, these burners 1 will be at fewer than three.
- Each burner 1 comprises, per se known, a duct comprising at least one combustion air inlet primary and containing at least the gas injector and a mixing chamber air / gas, this conduit opening into a combustion chamber of the mixture air / gas.
- the duct contains, between the injector and the air / gas mixing chamber, a venturi element. The detail of such burners will not be provided because many examples of embodiment of burners can be found in the literature.
- the heating device object of the invention, there is preferably a distinction two types of burners, namely a so-called master burner, fitted with a device 4 of the air / gas mixture ignition and of the burners 1, called slaves, which differentiate from the master burner by the fact that they are device-free ignition of the air / gas mixture.
- the device 4 for igniting the mixture air / gas will not be described in detail since it can be constituted in itself known from an electrical device of resistance, sparks or other type, from a night light or the like.
- Each burner comprises at least one device 11 for flame control. This flame control device 11 is thus common to all burners.
- This flame control device 11 can be consisting of an optical device, an ionization device, a infrared or any other means which ensures, when the flame, closing the supply to the common supply line gas from the gas supply source by means of a valve appropriate closure.
- this device 11 is a device to ionization consisting of a probe and a metal rod coming to cap the middle burner and extending along each of the burners adjoining this median burner. The cooperation of this flame control device 11 with the burner control means will be described below.
- Each burner 1, master or slave, is connected to the power source 3 in gas via the common gas supply line 2 and a tap on said pipe 2.
- Each connecting portion 5, produced between the source 3 of gas supply and a burner 1 is provided with a member 6 such that a solenoid valve ensuring the opening or closing of the link 5 between the burner 1 and source 3 of gas supply.
- This opening / closing of the link 5 is controlled by means of a suitable control device in depending on the power stage selected.
- the heater comprises a plurality of burners 1. Among these burners, there are at least two types of burners 1 differentiated by their heating power. Of preferably, the lower power burner 1 is placed between two other burners 1.
- burners are associated in operation according to combinations any predetermined randomly selectable for example by means of a programmer, each combination corresponding to a power stage. So it can be imagined a device heater with four burners with heating output differentiated.
- the first stage corresponds to the operation of the master burner of lower power
- the second power stage to the combination of lower power burner with power burner immediately above ...
- the top floor corresponding to a combination where the whole burners are working, i.e. are lit.
- the heating device therefore further comprises means for selecting a power stage corresponding to a predetermined combination of burner (s) in operation from a plurality of stages.
- selection means can be constituted by a programmer.
- it can be chosen, for a heating device comprising four burners, respectively called B1, B2, B3, B4, to define a first power stage corresponding to a supply of air / gas mixture of B1, the connections of the other burners remaining closed.
- a second power stage can be defined in which only the burner B3 of a power different from the burner B1 is lit.
- Other combinations can thus be defined, the total number of combinations being at most equal to 2 x , x corresponding to the number of burners in the installation.
- the means 7 for controlling the opening / closing of the connection of each burner control when passing from a power stage N to any new power stage P selected at any point, the opening of all the connections 5 of the burners 1 to allow, by automatic ignition of the flame of a burner by contact of the air / gas mixture expelled from the burner with the flame of an adjacent burner, the ignition of all the burners then the selective closing of the burner links 5 not included in the combination corresponding to the new selected power stage.
- This solution makes it possible to dispense with means of memorizing the combinations of burners coupled to means 7 for controlling opening / closing links. Thus, between each passage of a stage of power to another, all the burners are put into operation by automatic opening of links 5. On the other hand, this solution allows guarantee activation of the flame control device 11 by one any of the burners, regardless of the power level selected.
- the controlled opening / closing shutter member 6 of the link 5 between a burner 1 and the gas supply source 3 is a solenoid valve.
- the opening / closing of the solenoid valves can be controlled by means of electrical signals emitted from information emanating from a central control, such as a microprocessor. This central manages information relating to the power stage selected to determine the connections in front be open or closed respectively.
- the interval between two adjacent burner heads is chosen so as to allow self-ignition two adjacent burners in less than a tenth of a second.
- the burners 1 are arranged at at least partially inside a combustion chamber 8, itself housed inside a box 9 of a temperature-controlled air generator, this box 9 also containing at least one fan 10 for propelling in a room, at the desired temperature, the air circulating in the box 9.
- This air can thus be brought to temperature by conduction in contact with the walls of the combustion chamber 8.
- the exhaust air can consist exclusively of this air heated in contact with the walls of the combustion chamber 8 or also consist of the fumes from the combustion chamber 8.
