摘要： PURPOSE:To facilitate the transfer of a culture bed to a prescribed position even if the detection of the bed position is difficult, by detecting a culture bed with a sensor directly detecting an object, holding the detected bed and transferring to a position recognized by a rotary encoder and a pulse counter. CONSTITUTION:A transfer apparatus 1 moves at a high speed toward a target culture bed 4 while measuring the distance from a standard point defined by a rotary encoder. The motion of the apparatus 1 is slowed down near the culture bed 4 and a signal transmission route is switched from an optical sensor 8 to a control device. When the culture bed 4 is detected with the optical sensor 8, the transfer apparatus is stopped and a rod 19 is lowered with an electric cylinder 18 until it is engaged with the culture bed 4. The signal transmission route is switched from the rotary encoder to the controlling device and the culture bed is transferred by the signal transmitted from the rotary encoder until the distance of the transfer apparatus from the standard point reaches a prescribed level.

摘要： PURPOSE:To improve a function by a method wherein a feed rate of dust supplying to an incinerator is controlled and the proper amount of evaporation is reset when a deviation is generated between the amount of the average dust treatment at a given time during an optional period and the amount of the standard dust treatment. CONSTITUTION:The proper amount of evaporation is obtained from the amount of the standard dust treatment and the heat release value of the dust and is set to a control meter 17, then, it is compared with the amount of the proper evaporation by measuring of the amount of evaporation in boiler 20. According to this method, the feed rate of the dust supplying to the incinerator is controlled, and the deviation generated between the amount of the dust treatment at the passage point of the given time during the optional period and the amount of the dust treatment estimated based on the amount of standard dust treatment is computed by a comparison operator 25c. When the deviation thereof is larger than a predetermined value, the amount of average dust treatment at the remaining 8 hours is obtained again from the expected dust residue and the actual amount of the dust remaining in a dust pit 2, thereafter, the value thereof may be reset as the amount of standard dust treatment.

摘要： PURPOSE:To prevent production of NOX, by a method wherein the air fed to a fluidized-bed combustion furnace is divided into a primary air and a secondary air. CONSTITUTION:A furnace is provided with a first flow meter 12 for measuring the flow rate of a primary air, a second flow meter 14 for measuring the flow rate of a secondary air, an oxygen concentration meter 16 for measuring oxygen concentration in exhaust gas, and a computing part 17 which, based on output signals from the flow meters 12 and 14, and the oxygen concentration meter 16, computes an xygen concentration condition on a fludizied bed surface 18. A first regulating part 19 outputs a control signal which regulates the flow rate of a primary air, based on a deviation between an oxygen concentration condition outputted from the computing part 17 and a previously set oxygen concentration condition on the fluidized bed surface 18. A second regulating part 20 outputs a control signal which controls the flow rate of a secondary air so that an output signal from the oxygen concentration meter 16 attains a previously set value. This prevents production of NOX.

The combustion air 8-1 is blown into the upper part of the incinerator 1, and the blowing amount is adjusted by the adjusting damper 81. The furnace pressure is detected by a detection end 9 provided on the upper part of the incinerator 1, the detection output is inputted into an operator 61 by means of a transmitter 10, the operation output is inputted into the adjusting damper 81 to control the furnace pressure. As a result, in the case the furnace pressure is increased, the fluidizing amount of the combustion air is restricted to slow fluidization.

摘要： PURPOSE:To maintain substantially constant the state of combustion regardless of the variation in the charge to be incinerated that is charged into a furnace by changing the volume of air that is sent into a furnace from below its fluidized bed so as to maintain the temperature of the fluidized bed in a specified range of temperature by the output of furnace bed temperature detection means. CONSTITUTION:A calculator 11 carries out the calculation Y1 to calculate a fluidizing air volume setting value, SV1 from its brightness signal PV0. A calculator 12 carries out the calculation Y2 to calculate a fluidizing air volume setting value, SV2 from its fluidizing air volume setting value SV1 and furnace bed temperature detection signal PV1 of a furnace bed temperature detection end 6, and outputs the calculation result to a flow rate control regulator 13. A flow rate control regulator 13 outputs control signal MV to control a bypass control valve 3 to a bypass control valve 3 from a fluidizing air volume setting value SV2 and a fluidizing air detection signal PV3 for the fluidizing air volume that is sent into a fluidized layer 4 from a fluidizing air detection end 7, and controls the volume of air that bypasses to the free board 2 and controls the volume of the fluidizing air that is sent into the fluidized layer 4. With this arrangement the combustion quantity can be maintained substantially constant regardless of a change in the charge to be incinerated that is charged into the furnace.

摘要： PURPOSE:To control the pressure of a boiler drum without the generation of visible smoke and nitrogen oxide by selecting a control system whose output is smaller out of two control systems based on the application of a low selector and operating a dust collector. CONSTITUTION:Generally, there is only available a pressure control system which controls the quantity of dust based on the pressure of a boiler, directly manipulating a dust collector. However, the characteristic difference between the pressure of a boiler and the concentration of combustion waste gas oxygen will induce the generation of visible smoke in the shortage of oxygen. To solve this problem, attempts are made to cascade set a predetermined value of a forced air flow rate controller 18 based on an operation output MV01 and a reference value, compare it with a setting value V06 of a hearth oxygen concentration controller 21 through arithmetic operations and thereby obtain an operation output MV06. A low selector 28 selects a lower output out of the two operation outputs MV01 and MV06 and obtains an operation output Y04. This construction makes it possible to maintain the pressure of a boiler drum within a specified range and the concentration of waste gas oxygen within a proper range as well based on the control of the quantity of dust collection.
