Title: Combustion device
Inventor: KANEZAKI KOICHI
IPC: F23N3/08
Filed: 1988-02-24
Abstract: PURPOSE:To contrive the stability of combustion, by a method wherein an internal pressure difference is detected by a pressure difference detector, communicated with the delivery port of a fan and the inside of an exhaust top, while the internal pressure difference is controlled in accordance with a load. CONSTITUTION:Gas, sent from a gas control valve 5, is mixed with air, sent from a fan 5, and mixture is injected from a burner 4 to burn it in a combustion chamber 3. Combustion gas is discharged to the outside of a device through a heat exchanger 2, an exhaust tube 1 and an exhaust top 8. The delivery port of the fan 5 and the exhaust top 8 are provided with conduits 11, 12 to detect the internal pressure thereof respectively while the conduits 11, 12 are connected to a pressure difference detecting device 10. The combustion of the burner 4 is controlled by a method wherein a load is operated in a control unit 7 by comparing the hot-water temperature signal of a hot-water delivery thermistor 13, provided at the outlet port of the heat exchanger 2, with a set temperature while the supplying amount of gas of a gas control valve 6 is determined in accordance with the load. On the other hand, the torque of a fan 5 is determined in the control unit 7 so that a pressure difference, detected by the pressure difference detecting device 10, becomes an internal pressure difference between the delivery port 14 of the fan and the exhaust top 8 in accordance with the determined output of the gas control valve 6 whereby the fan 5 is actuated to supply the combustion air.

Abstract: PROBLEM TO BE SOLVED: To prevent a deterioration in a processing solution in a transfer path by forming an air tight flow passage up to a pump and sensing gas reaching a tube, so as to control the pump. SOLUTION: Air bubbles as the gas and the processing solution 2, in the tube 4 are separated in a separating vessel 5 and then, pass through a gas sensor 6 for sensing the air bubbles, by the tube 4.

On the other hand, in the processing solution 2 and the air bubbles, the air bubbles are returned into a processing solution container 1 through a flow passage by which the air bubbles have just come, by a back flow device 7. When this state is obtained, only the processing solution 2 exists from the processing solution container 1 to a back flow vessel, that is, the absent state of the air bubbles is obtained.  The processing solution 2 from which the air bubbles are removed by the back flow device 7 is fed into the pump 9 through the tube 4 and further, into an automatic developing machine processing vessel 10 as a fixed quantity of processing solution 2.
