IPC: F23L1/00
Filed: 1987-12-25
Abstract: PURPOSE:To prevent or reduce a vibratory combustion by a method wherein two layers of shielding plates are arranged between an air flow regulator plate and a blower in such a way as a flow of combustion air to be forcedly supplied from an outlet port of the blower into a combustion air supplying chamber just above the blower is deflected at both ends within the combustion air supplying chamber. CONSTITUTION:Air blown by a blower 13 passes through an air inlet port 12, flows between a shielding plate A16 in a blowing direction of the blower 13 and a lower part of a combustion case 11 and flows between a shielding plate A16 and a shielding plate B17. After this operation, a part of the air flows between the shielding plate B17 and an air flow regulating plate 14 and supplied into a burner 15 as a combustion primary air together with gas discharged from a nozzle 18. The remaining air passes through slits of the air flow regulating plate 14 and used within a combustion chamber 19 for a combustion as a secondary combustion air for the burner 15. A discharged gas after combustion passes through a heat exchanger 20 and is discharged from a discharging cylinder 21. With such an air supplying configuration, a variation in air pressure of the blower 13 is not directly transmitted to a combustion reaction surface of the burner 15, but is made uniform and then a local vibratory combustion at the combustion reaction surface is prevented.

Abstract: PROBLEM TO BE SOLVED: To enable washing treatment of a separation membrane with high washing efficiency by passing air from the secondary side of a membrane module to the primary side to perform washing treatment of the membrane module in the case of performing filtration by the membrane module by utilizing suction pressure through suction of the secondary side. SOLUTION: In this filtration method of polluted water, a hollow yarn membrane module is immersed into a filtration tank and the secondary side of the membrane module is sucked by using a pump P to perform filtrating treatment. In this case, filtrating treatment by the membrane module is performed for 30 minutes e.g. in a constant flow rate of 40L/hr and thereafter a valve communicating the pump P with the filtration tank is closed to stop filtrating treatment. Then, a compressor C is used and air is passed from the secondary side of the membrane module to the primary side at about 7kg/cm<2> pressure for 30 seconds to perform washing treatment of the membrane module. By this method, increase of suction pressure is little and filtration of polluted water is stably performed for a long time.
