摘要： PROBLEM TO BE SOLVED: To enable discharging of an incineration discharge gas into air by subjecting a chlorine-contg. plastic waste to dry distillation, absorbing the hydrogen chloride gas produced by the dry distillation to water to collect, and incinerating the carbon residue after the dry distillation. SOLUTION: A waste of polyvinyl chloride products is put in a furnace 2 for dry distillation and incineration, then a boiler 6 and a heating furnace 8 are operated to produce an overheated vapor, which is supplied to the furnace 2 to dry distillate the waste. The discharged gas containing the overheated vapor, the gas produced by dry distillation and hydrogen chloride gas produced by dry distillation is sent through a gas cooling device 14, a hydrogen chloride concentration meter 6 and a switching valve 15 to a collecting device 3 for hydrogen chloride, where the discharged gas is successively introduced to bubble in three water tanks 16 to 18. Thereby, the overheated vapor in the discharged gas is condensed into water and recovered. The hydrogen chloride gas is absorbed by the water while the gas produced by dry distillation is passed through the water tank 18 and then supplied by a blower 24 to a burner of the heating furnace 8 with air for combustion. Thus, the gas produced by dry distillation is rendered harmless.

摘要： PURPOSE:To increase an absorbing amount of carbonic acid gas and to get hot water of which temperature is always kept at its appropriate value by a method wherein discharging gas ignited is guided from a gas burner directed downwardly in a combustion chamber toward a hot water surface in a hot water storing tank into a discharging gas passage around the combustion chamber, water is dispersed from a water dispersion header and the hot water in the hot water storing tank is circulated in the water dispersion header. CONSTITUTION:As a tap water plug 17a or a plug in a shower 17b is opened, a reduction in pressure in an outlet side hot water feeding pipe 18 is detected by a hydraulic pressure gauge 20, a hot water feeding pump 19 is energized and then hot water is supplied from the hot water storing tank to a hot water discharging pipe 18. As a hot water surface 2a of the hot water storing tank 2 is decreased less than a specified level and this is detected by the level gauge 21, water is supplied from a tap water pipe into a water dispersion header 11 through the water supplying pipe 13 and a gas burner 6 is ignited. Water droplets injected from the water dispersion header 11 are heated by the thermal transmitting plate 3 and the discharged gas B in the discharged gas passage 5. Hot water in the hot water storing tank 2 is heated by a flame A. When a reduction in temperature of hot water in the hot water storing tank 2 is detected by a water temperature meter 22, a selector valve 14 is changed over to stop water feeding, resulting in that the circulation pump 15 is energized to cause the hot water in the hot water storing tank 2 to be circulated again in the water dispersion header 11 through the circulating water pipe 16 and the outlet of the water supplying pipe 13 and then heated.

摘要： PURPOSE:To prevent sea pollution emitted from an offshore structure by forming recessed and protruding parts which fit with each other to the upper ends of support columns and the bottom surface of a platform ship. CONSTITUTION:Supports 1 are preliminarily transported to an anchoring sea area and the lower ends thereof are fixed to the bottom of the sea. After a platform ship 3 is loaded with sewage, the platform ship 3 is towed to the sea area, where the supports columns are constructed, by a tugboat. The platform ship 3 is sunk by injecting seawater ballast in a buoyancy control tank to fit the protruding parts 7 thereof into the recessed parts 4 provided to the upper ends of the support columns and fixed to the upper ends of the supports 1 in a freely detachable manner. Thereafter, sewage is treated with a sewage treatment plant 2 arranged on the platform ship 3. When treated water is discharged to the sea and the treatment of all of the sewage received in the platform ship 3 is completed, the platform ship 3 is floated to remove the protruding parts 7 from the recessed parts 4. By this method, a shortage of treatment facilities can be eliminated.

摘要： PURPOSE:To reduce thermal NOX through slow combustion by forming a flat flame inside the furnace by ejecting from ejection holes a fuel-air premix produced by mixing raw gas and primary air in the main body of a gas burner and on the other hand by ejecting into the furnace in a manner of diffusion from ejection holes the raw gas flowing through a communicating pipe and a gas chamber. CONSTITUTION:When raw gas A is blown into an outer end opening 5a from an ejection hole 13 of a primary gas nozzle 12, primary air B is drawn in by the ejector action at a venturi tube section 5. The raw gas A and the primary air B are preliminarily mixed to form a fuel-air premix C, which is ejected into the furnace 15 through premix ejection holes 11A, 11B, 11C in a secondary gas nozzle 4 to form a stabilized flat flame. With the primary air B drawn in amounting to less than the quantity required for the combustion, the combustion is thinly supplied with fuel so that the formation of thermal NOX is suppressed. The raw gas A flowing through a communicating pipe 14 from the primary gas nozzle 12 is sent into a gas chamber 8 under pressure and from hence ejected into the furnace 15 through unmixed gas ejection holes 10. The raw gas A is ejected in a manner of diffusion without being premixed with air and made to burn slowly. The combustion is slow and stabilized, free from peaks in temperature, and results in the reduction of thermal NOX.
