摘要： PURPOSE:To eliminate the variation in the air-fuel ratio caused by the change in the preheating temperature of combustion air by calculating the ejector air flow rate necessary in accordance with the temperature detected value of combustion air of the title burner. CONSTITUTION:In a method of controlling the combustion of a suction type radiant tube burner 2 used for heating a material to be processed in a heat processing furnace, the temperature of combustion air on the inlet side of the burner is detected by a temperature meter 20. A control operating apparatus 21 calculates an ejector air flow rate from a relation formula of a ratio between a predetermined combustion air and air (ejector air flow rate/fuel flow rate) from the detected temperature. Based on this calculated value, the ejector air flow rate is controlled. As a result, it is possible to eliminate the variation in the fuel-air ratio caused by the variation in the preheating temperature of combustion air.

CONSTITUTION:A steel sheet 11 is continuously annealed in the continuous annealing furnace consisting of the preheating furnace 2, a direct-fired oxygen free furnace 1 and a furnace 4 contg. gaseous atmosphere. When the annealing is stopped due to a line trouble, the furnace pressure controlling damper 7 provided in a waste gas flue 14 of the preheating furnace 2 is closed. The cutoff valve 24 for a gaseous fuel to be supplied to the direct-fired furnace 1 and a cutoff valve 25 for a combustion air are simultaneously closed to stop the fuel combustion in the furnace 1, an inert gas such as N2 is supplied from pipelines 17 and 19 to prevent the formation of a negative pressure in the gaseous atmosphere in the annealing furnace, and the oxidation of the steel sheet 11 by the atmosphere intruding from the outside of the furnace is obviated. Conversely, when the furnace pressure is abnormally increased, the increase is detected by a furnace pressure detector 23, the furnace pressure controlling emergency damper 20 provided to the preheating furnace 2 is opened, and the pressure of the atmosphere in the annealing furnace is held at an appropriate positive pressure.

摘要： PURPOSE:To inject fluid in the uniform and laminar state in slit nozzle opening part by providing a flow regulating chamber formed of a pressure equalizing chamber, flow rectifying reinforcing plates and flow rectifying plates within the slit nozzle header of an injector for fluid. CONSTITUTION:Liquid such as cooling water enter the inside of a slit header 2 from a lead-in pipe 1, passes through plural pieces of outflow holes 4 provided at random in a pressure equalizing plate 3 and ejects into a pressure equalizing chamber 5. Here, the dynamic pressure of the fluid decreases and the fluid is uniformalized of mixed dynamic and static pressure, after which it passes flow rectifying reinforcing plates 6 and enters a flow rectifying chamber 7. In the chamber 7, the disturbance of the liquid flow produced by the plates 6 is regulated by flow rectifying plates 8 and is injected uniformly in the laminar flow state from a slit 9. Since the fluid is rectified of flow, there is no uneven rate of injection, the shape is compact, the strength of the nozzle part is high and fluid injection is accomplished efficiently.
