摘要： PURPOSE:To remove almost completely, as well as phosphoric acid ion responsible for the occurrence of red tide, such harmful substances as COD, heavy metals (mainly iron), etc., present in chemical cleaning waste waters including citric acid cleaning liquid for the removal of scale and the phosphoric acid rest-proofing liquid to within the effluent standard values. CONSTITUTION:Calcium hydrozide or calcium oxide is added to waste water to make it alkaline, whereupon heavy metals (mainly iron), citric acid, and phosphates present in the waste water are precipitated in the forms of heavy metal hydroxides, calcium citrate, and calcium phosphate. Furthermore, a persulfate is added to the supernatant liquor of the waste water in another container in an amount more than equivalent of COD present in the liquor to decompose the COD components by oxidation. In this method, since calcium citrate is hard to sediment completely because of its comparatively high solubility, the citric acid as a COD component in the waste water is oxidized by a perfulfate for decomposition. Thus, harmful substances can be removed to within the effluent standard values as shown in the table.

摘要： PURPOSE:To prevent the loss of an SOx gas resulting from the condensation of moisture so that a sample gas can be stably supplied to an analyzer (SOx meter) by effectively removing dust and waste combustion gas of a pressurized fluidized bed boiler under a high-temperature and high-pressure condition simultaneously with the sampling of the gas. CONSTITUTION:Firstly, the pressure of a sampling system is adjusted to the pressure in the furnace A of a pressurized fluid bed boiler. Secondly, the temperatures of a gas sampling probe 1, ball valve 3, ball-filled filter 4, precision filter 7, and dehumidifying unit 11 are raised to such a temperature that does not allow moisture to condense by heating 10 a heat insulating member 9. Then an air compressor 11b which is the high-pressure air generating source of the unit 11 and a gas analyzer 12 are operated. Thereafter, the pressure of the sampling system is adjusted to the pressure of a gas introduced to the unit 11 by operating a pressure regulating valve lid for the unit 11 after fully opening the valve 3 and a stop valve 6. The dust-free, dehumidified high-temperature and high-pressure clean waste combustion gas is stably supplied to a gas analyzer 12 at a flow rate of 1-3l/min after the pressure of the gas is reduced to the atmospheric pressure through a pressure reducing valve 8.

摘要： PURPOSE:To reduce the emission of nitrous oxide (N2O) in the exhaust gas from the combustion in a pressurized fluidized bed boiler. CONSTITUTION:Air for combustion (or oxygen) 19 is injected from nozzles (for air for combustion) 18 toward the surface of a fluidized bed 1 and toward bubbles where they burst so that fine particulates of unburned carbon discharged from the fluidized bed 1 undergoes combustion. The surface temperature of the fluidized bed 1 is adjusted to a range of 900 to 1,000 deg.C so as to make N2O easily decomposable under heat.

摘要： PURPOSE:To accomplish the quality improvement of gas in high efficiency with energy saving by burning part of a gas comprising tar, ammonia and a combustible gas produced by gasifying hydrocarbons followed by decomposing both the tar and ammonia through catalytic reaction. CONSTITUTION:A combustible gas comprising (A) a combustible gas such as CO, H2 and CH4 produced by gasifying hydrocarbons, (B) tar and (C) ammonia is incorporated with (oxygen enriched) air or oxygen to burn part of said gas followed by contact at >=800 deg.C with a catalyst containing at least one substance selected from Ni, Cr and Fe. Thereby the tar is decomposed into CO and H2 and the ammonia into N2 and H2, thus accomplishing the quality improvement of the combustible gas.

摘要： PURPOSE:To simply and safely treat waste gas containing ammonium by connecting an exhaust gas pipe from an inner equipment to the additive air piping of a boiler fire furnace, in a power plant using simple substance or mixture of ammonium as operating fluid. CONSTITUTION:Nitrogen gas contained in a vessel 21 is guided out to a piping 12 by means of a pump 18 and then exhausted to out of the line via an evaporator 1, a turbine 5, a condenser 7 and a piping 24. After the air in the line is substituted by the nitrogen gas, liquid ammonium and the like in a vessel 14 is compressed by a pump 15 and supplied to the evaporator 1, the turbine 5 and the condenser 7 in sequence. Thereafter, aqueous ammonium which is condensed by the condenser 7 into fluid is returned to the inside of the vessel 14 by means of the pump 9. In this case, noncondensable gas remaining in the condenser 7 and containing ammonium is supplied by a pump 17b i.e., noncondensable gas extracting means 17 via an extraction steam pipe 17a to the additive air piping 30 of a boiler fire furnace line B so that it is burned in a fire furnace 32.
