(Industrial Application Field) The present invention relates to a method and mechanism for regulating the amount of heat of generated gas. (Prior Art) The gas generation process is accompanied by a process of adjusting the amount of heat by mixing the generated gas with an operating fluid such as a high-calorie gas. Therefore, the conventional method and mechanism for adjusting the amount of heat were developed.
This will be explained using figures. Reference numeral 1 is a gas generation process, 2 is a generated gas path, 3 is an operating fluid path, 4 is a mixing section, and 5 is a mixed gas path. Paths 2 and 3 are provided with flow rate sensors 6 and 7, respectively, and path 5 is provided with flow rate sensors 6 and 7, respectively.
A calorie sensor 8 is provided, and a calorie controller 9 whose input is the output of the calorie sensor 8 is provided. Further, a flow rate control valve 10 is provided in the path 3, and a flow rate control loop 12 is constituted by this flow rate control valve 10, the flow rate sensor 7, and the flow rate controller 11, and the flow rate setting value of the flow rate rate meter 11 is as follows. In the calculator 13, the flow rate of the generated gas measured by the flow rate sensor 6 is multiplied by a coefficient derived from the calorific balance equation in mixing, and the operation output of the calorific value controller 9 is added to this. are derived and set. Now, the respective flow rates of the generated gas and the operating fluid are F A ,
When F B and the respective calorific values are Q A and Q B , and the desired calorific value of the mixed gas is Q S , the following calorific balance formula holds true. Q S =Q A F A +Q B F B /F A +F B ...(1) Then, the required flow rate of the operating fluid can be determined by the following equation, which is a modification of equation (1). F B = Q S −Q A /Q B −Q S F A ...(2) Conventionally, the coefficient γ B (=(Q S −Q A )/
(Q B −Q S )) is multiplied by the flow rate F A of generated gas measured by the flow rate sensor 6, and then added to this by the calorific value controller 9.
Calculation is performed in the computing unit 13 to add the manipulated output MV of F B ′=γ B F A +MV ……(3) This value F B ′ is set in the flow rate controller 11 to control the flow rate of the manipulated fluid. By doing this, the amount of heat is adjusted. Conventionally, the coefficient γ B has been treated as a constant, that is, the coefficient γ B is calculated based on the calorific value of the generated gas at a process operating rate of 100%, and is a constant. (Problem to be Solved by the Invention) As mentioned above, in the past, the coefficient γ B was calculated by assuming that the calorific value of the generated gas was constant, but in the actual process, the calorific value of the generated gas was
As shown in the figure, it fluctuates depending on the operating rate. Therefore, if the operating rate of the process fluctuates and a difference occurs between the amount of heat of the generated gas when the coefficient γ B is set as a constant and the amount of heat of the actual gas generated, the coefficient γ B is used. There is a difference between the required amount of operating fluid obtained by The desired amount of heat Q S
It deviates from the The correction operation for this deviation has to be carried out only by detecting the deviation in the calorific value of the mixed gas using the calorific value controller 9 and varying the aforementioned operational output MV. There is a problem that the heat amount adjustment of the mixed gas has poor followability with respect to fluctuations in the amount of heat, and changes in the amount of heat are likely to occur. The present invention aims to solve the above problems. (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention first provides a method for mixing generated gas and operating fluid in a gas generation process, by adjusting the flow rate of the generated gas and the amount of heat in the mixing. In the method for adjusting the amount of heat, the value obtained by multiplying the coefficient derived from the balance equation and adding the operating output of the amount of heat amount controller to this value is set as the set value of the flow rate controller that constitutes the flow rate control loop of the operating fluid. The coefficient is
The gist of the present invention is a method of adjusting the amount of heat, which is derived as a function of the operation rate, based on the correspondence between the operation rate of the process and the amount of heat of the generated gas. In addition, the present invention configures a mixing system for the generated gas and operating fluid in the gas generation process, multiplies the calorific value of the gas generated gas by a coefficient derived from the calorific balance equation in mixing, and multiplies the calorific value of the gas generated gas by a coefficient derived from the calorific balance formula in mixing, a first computing unit that derives a setting value of a flow rate controller constituting the flow rate control loop for the operating fluid by applying the operating output; Another gist is a heat amount adjustment mechanism provided with a second arithmetic unit that outputs an output to the arithmetic unit. The second arithmetic unit that derives the generated gas calorific value from the operating rate of the gas generation process is provided with means for storing the correspondence between the operating rate and the calorific value as a data table or as a relational expression. By using it in calculations, the amount of heat can be derived from the operating rate. (Function) In the above configuration, the present invention multiplies the flow rate of the generated gas by a coefficient derived from the calorific balance equation in mixing during the operation of the gas generation process and the accompanying calorific value adjustment process. The amount of heat is adjusted by setting the value obtained by adding the operation output of the heat amount controller to the set value of the flow rate controller that constitutes the flow rate control loop of the operating fluid. At this time, the coefficient is derived as a function of the operation rate based on the correspondence between the operation rate of the process and the calorific value of the generated gas. Therefore, when the operating rate of the process fluctuates and the amount of heat of the generated gas changes, refer to the correspondence between the operating rate and the amount of heat that has been obtained through prior measurement and stored. The actual calorific value of the generated gas can be derived from the operation rate,
By deriving the aforementioned coefficient based on the calorific value of the generated gas derived in this way, and multiplying this coefficient by the flow rate of the generated gas, a flow rate of the operating fluid that is equal to or close to the true required amount is obtained. be able to. In this way, by lowering the ratio of the operation output of the calorific value controller to the set value of the flow rate controller, it is possible to improve the followability of the calorific value adjustment of the mixed gas to fluctuations in the operating rate. Even when the operating rate fluctuates, the amount of heat in the mixed gas can be stabilized. (Example) Next, an example of the present invention will be described with reference to FIG.
In FIG. 1, the same reference numerals are given to the same components as those in FIG. 2. In FIG. 1, reference numeral 1 is a gas process, 2 is a generated gas path, 3 is an operating fluid path, 4 is a mixing section, and 5 is a gas process.
is the mixed gas path. Paths 2 and 3 are provided with flow rate sensors 6 and 7, respectively, and path 5 is provided with a calorie sensor 8, and a calorie controller 9 whose input is the output of this calorie sensor 8. Further, a flow rate control valve 10 is provided in the path 3, and a flow rate control loop 12 is constituted by this flow rate control valve 10, a flow rate sensor 7, and a flow rate controller 11.
The flow rate setting value of 1 is determined by the first calculation unit 14,
The flow rate of the generated gas measured by the flow rate sensor 6 is multiplied by a coefficient derived from the calorific value balance equation in mixing, and the operation output of the calorific value controller 9 is added to this to derive and set. ing. The flow rate of the generated gas used for deriving the coefficient in the first calculator 14 is derived from the operating rate of the process 1 in the second calculator 15 and outputted to the first calculator 14. The coefficients are derived using That is, in the same way as described above, the respective flow rates of the generated gas and operating fluid are F A and F B and the respective calorific values are Q A and Q B , the desired calorific value of the mixed gas is Q S , and the calorific value controller 9 is Letting the operating output of MV be MV, the flow rate controller 11 is set to a value F B obtained by the following equation. F B = Q S −Q A (LA)/Q B −Q S・F A +MV ……(4) In equation (4), Q A (LA) is the generation as a function of the utilization rate LA. It represents the flow rate of gas.
As mentioned above, Q A (LA) in equation (4) is derived from the operation rate LA of process 1 in the second computing unit 15,
Then, the set value F B is derived in the first arithmetic unit 14 using the Q A (LA). As an example, there is a correspondence relationship between the operating rate LA of the process 1 and the calorific value Q A of the generated gas as shown in FIG. If you do so, the second
The computing unit 15 can derive the amount of heat by inputting the operation rate. The correspondence relationship can be stored as a data table or as a function expression. Next, the operation of the present invention and the conventional method will be explained with reference to specific numerical examples. In other words, the operating rate in process 1
The correspondence between LA and generated gas calorific value Q A is shown in Figure 3, and the operation when the operating rate changes from 100% to 80% will be explained. Occupancy rate is 100% and 80%
The conditions for this are shown in the table below.

The set value of the operating fluid excluding MV can be made equal to the true required amount regardless of fluctuations in the operating rate, and the value of MV can be minimized, so the calorific value of the mixed gas can be adjusted to the desired value Q. It can be stabilized in S. Of course, there may be an error between the calorific value of the generated gas derived from the operating rate in the second computing unit and the actual calorific value of the generated gas due to approximation of the correspondence relationship, but such error is small and therefore The above is not a problem and can be improved by performing more accurate approximation.

The setting value of the operating fluid other than , will deviate from the true required amount when the operating rate changes, and in the heat balance equation (1) mentioned above, the setting value of the operating fluid will be set as a heat amount different from the desired heat amount of the mixed gas. Therefore, such a deviation in the amount of heat must be corrected by MV, so the followability of the amount of heat adjustment is poor and fluctuations in the amount of heat in the mixed gas are likely to occur. (Effects of the Invention) As described above, the present invention, in mixing the generated gas and the operating fluid in the gas generation process, multiplies the flow rate of the generated gas by a coefficient derived from the heat balance equation in the mixing, and In the method of adjusting the amount of heat, the value obtained by adding the operation output of the amount of heat amount controller to the operating output of the amount of heat amount controller is set as the setting value of the flow rate controller constituting the flow rate control loop of the operating fluid, the coefficient is determined based on the operating rate of the process and the generated gas. Since it is derived as a function of the operating rate based on the correspondence relationship with the calorific value of can be set to a value equal to or close to the required amount, and the operation output can be minimized, resulting in the effect that the amount of heat of the mixed gas can be stably adjusted to a desired amount of heat. Note that the present invention can also be applied to processes other than continuous processes.
