摘要： The incineration combustion chamber has a hollow casing with top outlet (12) and closed at the bottom by a baseplate (14) with a central opening through which oxidation gas is introduced under pressure, also a series of peripheral ones for this gas (16). Heat transfer particles (32) inside the casing (12) fluidise the gas delivered, and a mechanism (28) is included for loading the refuse into it. The baseplate can be conical, enclosed in a chamber (18) to which the gas is delivered, and with a pipe (24) connected to its central opening. A smaller pipe (19) is mounted inside this one, to form an intervening annular space through which any ash etc. is discharged.

摘要： PURPOSE:To improve the contact between each of the heating pipes and fluidizing medium and to raise the collection rate of heat in a fluidized bed when heat is collected in a fluidized bed through heating pipes arranged there by a method wherein groups of heating pipes of many stages are arranged so that they are intersected at right angles in the direction of the bed height of the fluidized bed. CONSTITUTION:Groups 2 of evaporating pipes are made up by arranging a plurality of evaporating pipes 2a in parallel in a fuidized bed furnace body 1 and connecting them to a header 5. A group of evaporating pipes 4 formed similarly by arranging a plurality of evaporating pipes 4a in parallel and connecting them to a header 5 is arranged so that it falls at right angles with said group 2 of evaporating pipes. On the side of the group 4 of evaporating pipes a group 6 of overheaters is arranged so that the latter is parallel to the former. In this manner, when the supply water in the groups 2, 4 of evaporating pipes is heated and reaches a drum 13 through pipes 12a, 12b before the starting of the fluidized bed is completed, the fluidizing medium is mixed and stirred well and heating efficiency is raised because each group 2, 4 of evaporating pipes are arranged at right angles with each other.

摘要： PURPOSE:To provide a method of operating swirling jet flow bed furnace for combusting EP-ash, according to which temperature of exhaust gas at the outlet of the furnace is kept higher than the dew point of vapor of sulfuric acid contained in the exhaust gas, and the exhaust gas is cooled rapidly through detection of temperature of the subsequent exhaust gas flow, whereby it is enabled to operate the furnace in stable manner, while preventing sticking of dust to the wall of the furnace and inner surface of ducts. CONSTITUTION:EP-ash is supplied from EP-ash supplying means 8 and it is swirled forcibly together with swirling medium 10 such as sand. Combustible components in the ash are combusted and carbons contained in the ash is also combusted, so that temperature of the gas in the furnace is raised. Temperature of the combustion gas is detected by detector 12 and controlled such that it is 700-730 deg.C in the swirling jet flow bed and 650-700 deg.C at free board section 13. Combustion gas is passed through outlet 14 of the furnace and delivered into duct 15. Cooling air supplying means 16-19 are provided at the top of the furnace for cooling the combustion gas rapidly to about 500 deg.C. By the cooling the combustion gas, compounds having a low melting point, contained in combustion residue, are solidified, so that sticking of the residue to the wall of the furnace or other portions of the system can be prevented.

摘要： PURPOSE:To control the temperature in the layer of the moving layer incinerator by means of water cooling walls which surround the moving layer portion of the incinerator and water cooling pipes provided within the moving layer, thereby lowering the time constant of the incinerator and, hence, burning up the substance to be disposed effectively. CONSTITUTION:A porous plate 2 provided in the lower portion of a moving layer incinerator 1 is lined up by cooling water pipes and a moving layer 4 has cooling water pipes provided therein and also coiled water cooling pipes 8 mounted so that they will form a water cooling wall 9. Then, the temperature in the layer of the incinerator 1 is transmitted from a temperature emitter 10 to a regulating box 13, which sends signals for controlling the amount of the cooling water which flows through the cooling water pipes 6 inside the layer and the water cooling wall 9. The cooling water fed from a pump 14 flows, after regulated in the amount by a control valve 16, through the cooling water pipes 6 and the cooling wall 9 and then exhaused in the form of vapour. Accordingly, it is possible to lower the time constant of the incinerator 1 and thereby to burn up the substance to be disposed which contains nitrogen compounds such as EP ashes without producing any nitrogen oxides.

摘要： PURPOSE:To provide a swirling jet flow bed furnace for combusting EP-ash, in which height of the hollow sleeve portion of the furnace is made sufficiently high for completely carrying out combustion of ammonia and for proceeding reaction of non-reacted substances, whereby sticking of sticky substances to the wall of the furnace and inner surface of the ducts can be prevented and it is enabled to operate the furnace continuously. CONSTITUTION:In combusting EP-ash in a swirling jet flow furnace, combustion gas is made to stay long the the furnace so as to completely combust ammonia produced by decomposition of ammonium sulfate. Ammonium sulfate is decomposed into NH3 and SO3 in swirling jet flow bed 1, and NH3 is in turn decomposed into nitrogen gas and water, whereas SO3 is decomposed into SO2. Here, in order that these decomposed substances may not be re-united in the combustion gas after cooling, height of hollow sleeve portion 13 is made sufficiently high, preferably more than 5 meters, to lower the content of ammonia at the outlet of the sleeve portion 13. Further, the gas speed is designed at 0.5-1.0 m/s, preferably at 0.7 m/s, so that reaction of non-reacted substances be promoted in the sleeve portion 13.
