制御装置を得ることをその目的とする。However, in the case of exhausting to the outside through a common exhaust pipe, one exhaust affects the other exhaust, and the balance between the fuel amount and the air amount is lost, so that the optimum combustion is performed. Is not obtained. For this reason, for example, Japanese Patent Laid-Open Publication No. 64-38516 has previously proposed an apparatus in which two supply cylinders are connected to each other by a connecting pipe for connecting the two supply cylinders so as to prevent the influence of exhaust gas on the other side as much as possible.
However, in this case, since a part of the air with the higher air pressure flows to the other side, the amount of the air with the higher air pressure is reduced, which is disadvantageous. Further, there is also known an apparatus in which a predetermined air volume is obtained for each combustor by feedback control, but this apparatus not only requires an air volume sensor for each combustor, but also requires complicated control means. There is a problem such as becoming. An object of the present invention is to obtain a combustor air volume control device free of such a problem.

可能である。For example, the room temperature detected by the temperature detecting means 8 is lower than the temperature set by the temperature setting means 7, and the stage 3 of the fuel supply amount to the combustor A is selected.
Since the floor heating panel temperature detected by the temperature detecting means 8 is relatively higher than the temperature set in the step (b), when the stage 1 of the fuel supply amount to the combustor B is selected, each blower 3 is selected. The predetermined rotation speed, that is, 2,000 rotations in the combustor A,
In the combustor B, the blower 3 rotates at 1400 revolutions. The amount of air blown by the number of rotations is the number of rotations of the blower, which is determined in advance by experiments in consideration of the mutual exhaust,
That is, since the amount of air is blown in each of the combustors A and B in consideration of the influence on each other's exhaust, the amount of air supplied in each of the combustors A and B is correct according to the amount of fuel, and stable combustion is obtained.
In the above-described apparatus, the blower 3 is provided on the supply side of the combustors A and B, but may be provided on the exhaust side. Further, the above-described embodiment shows an example in which air is supplied from the outside and exhausted to the outside, but it is needless to say that the present invention can be applied to a type in which only exhaust is performed by a common exhaust cylinder. Further, as the fuel supply means 1, instead of the electromagnetic pump 2, a head-type fuel supply means for supplying fuel using a head can be used, and the head-type fuel supply means and each of the combustors A, B An electromagnetic flow control valve is provided in a passage connecting the electromagnetic flow control valve and the throttle amount of the electromagnetic flow control valve is adjusted according to the deviation between the temperature setting means 7 and the temperature detection means 8 so that the fuel amount is controlled. Is also good.
Note that the matrix data map can be multiplexed, and in that case, more complicated processing using a plurality of variables can be performed. For example, in addition to the above, in addition to the above, a matrix data map in which a change in air pressure or a change in combustion air temperature (air temperature) or the like is created and stored in the storage means 11, and a change in air pressure or combustion air temperature (air temperature) is stored. It is also possible to take into account the correction due to the change in the rotation speed of the blower. Further, it is also possible to increase the number of combustors exhausted to the exhaust stack 5.
