摘要： PROBLEM TO BE SOLVED: To prevent the filling of the circulating tank of an absorbing tower with fine air bubbles when salts are conc. in the absorbing tower or the diameter of the absorbing tower is contracted or the amt. of an absorbing soln. is increased and to keep a liquid surface level constant. SOLUTION: A wet exhaust gas desulfurizing method wherein the combustion exhaust gas discharged from the combustion device of a boiler or the like is brought into contact with an absorbing soln. in an absorbing tower 2 to treat sulfur oxide in the exhaust gas and the absorbing soln. having absorbed sulfur oxide is stored in the circulating tank 7 of the absorbing tower and, after a defoaming agent is supplied to the absorbing soln. during the storage of the absorbing soln., the absorbing soln. is again brought into contact with the combustion exhaust gas, there is no special limit as the defoaming agent, it is pref. to use a defoaming agent based on a higher alcoholic surfactant. It is unnecessary to make the concn. of the defoaming agent in the absorbing soln. too high and, if the defoaming agent is supplied so that the concn. thereof is set to 3-50 ppm, effect is obtained.

摘要： PURPOSE:To prevent the fusion sticking of low melting point compounds on account of dust deposition in a duct by cooling exhaust gases after incineration of heavy or crude oil ash. CONSTITUTION:Heavy or crude oil ash is carried from an ash storage tank 2 to an incinerator 3 by air supplied by a Roots-blower 1. In the incinerator 3, heavy or crude oil ash is incinerated with combustion air supplied by a forced ventilator 7. Cooling air from a cooling ventilator 8 and water from a cooling water pump 10 are sprayed from the top of the incinerator 3 into the furnace and cool hot combustion gases in the incinerator 3. If water or steam alone is used to cool combustion gases as the combustion gas cooling medium sprayed from the top of the incinerator 3, it has sufficient cooling effect without increasing the quantity of exhaust gases after being cooled too much. Gas temperature about 700-800 deg.C in the incinerator 3 is cooled to 300-400 deg.C at the outlet of the incinerator 3 by water or steam and cooling air sprayed from the top of the incinerator 3. By doing so, sticking of low melting point compounds to exhaust gas ducts and dust collectors can be prevented.

摘要： PROBLEM TO BE SOLVED: To provide a shot cleaning apparatus and its operation method, in which a flow rate of shots of steel balls is easily variable in response to load change or increase of pressure loss in a GGH (gas-gas heater) without upsizing the apparatus.
SOLUTION: Dust adhered to heat transfer pipes 5 is removed by scattering shots from a feeder 1 on the pipes 5 which performs heat exchange between the inner fluid and dust-containing gas. Shot circulation in the apparatus is controlled by varying the shot-transfer speed of the feeder 1 by employing a controllable motor, e.g. provided with an inverter. The shots are spontaneously dropped all the time as required from a bypass chute 11 provided in the feeder 1. Further, a specified amount of shots are added all the time from a feeder 10 of a shot tank 9 in the outside of the system to the shot circulation system. In this case, operation is kept in a constant speed (maximum capacity) in the shot-transfer system including a shot-transferring bucket-conveyor 8, a shot distributor 4, a dust separator 6 and a shot discharger 7, etc.
