摘要： PURPOSE:To obtain the instantaneous weight and flow rate of pulverized coal by measuring the pressure loss and carrier air flow rate of a fuel supply pipe. CONSTITUTION:The flow rate Ga of carrier air is obtained by an air flow meter 11 and the pressure loss DELTAPc of a feed air pipe 4 due to a pulverized coal flow is obtained by pressure detectors 12 and 13 and a differential pressure gauge 14. The pressure loss DELTAPa only due to a carrier air flow is calculated from the flow rate Ga of carrier air. A function equation f(Ga) used for this conversion is derived from measuremen data obtained previously while only the carrier air flows. Then, the pressure loss ratio alpha=DELTAPc/DELTAPa is calculated from the pressure loss DELTAPc and pressure loss DELTAPa. Then, the ratio of said flow rates Gc and Ga of the pulverized coal and carrier air, i.e. solid-gas ratio m=Gc/Ga is calculated from m=(alpha-1)/K. This constant K is calculated previously from measurement data in the flow rate of the pulverized coal. Then, the flow rate Gc of pulverized coal is found from Gc=m.Ga.

摘要： PURPOSE:To suppress the transient rise in nitrogen oxide of the exhaust gas by changing forcibly the ratio of the combustion air in two stages for a certain time at the time of starting or stopping a coal pulverizing machine or at the time of changing the grain size of the pulverized coal. CONSTITUTION:The flow rate (TS flow rate) of the combustion air in the second stage is measured by a sensor 1 and its output is compared with a set value by a comparator 2 and the deviation is calculated by a proportional integrator 3 and it is supplied to a damper 4 as an operation value by the TS flow rate control. The set value is given through a change rate limiting device 8 after the TS flow rate set value is corrected by a correction section 7 given by a function generator 6 based on the whole air flow rate instruction value from an instruction section 5 is corrected by a correction section 7. The correction data supplied to the correction section 7 is the data given by correcting the set value outputted from a TS ratio setting section 9 by a correction section 10, and, for example, the starting and stopping of four coal pulverizing machines are detected by a detector 12 and they are generated from a function generator 13. And, an increase or decrease in change-overs of the coal pulverizing machine is detected by a detector and a correction data is generated from a function generator 16. A balance between the air and coal is maintained and a rise in the concentration of NOx is suppressed.

SOLUTION: A power plant is provided with boilers, steam turbines, steam lines, and fuel lines. The supplied quantity of steam to each steam turbine is decided based on the power load allocation corresponding to the power demand.

The required pressure of each boiler which secures the generated quantity of steam of each boiler is calculated and each boiler is controlled based on the required pressure. The required pressure of each boiler is calculated from the formula, where αB(i), αT(i), and fB(i) respectively represent the generated steam allocation ratio, supplied steam allocation ratio, and generated steam allocation and fT(i), f(i)(i+1), and R respectively represent the supplied steam allocation, inter-boiler flow rate, and pipe resistance. In addition, PB(1) and RB(1) respectively represent the set steam pressure and pipe resistance of a reference boiler.
