| PROBLEM TO BE SOLVED: To provide a separatorless boiler, in which a desired degree of dryness can be obtained while the height of an upper header is suppressed and which has a small amount of holding water.SOLUTION: The boiler includes: a boiler body 20 configured in such a manner that when combustion using a burner 30 is stopped, a water level inside a water pipe 23 is lower than an upper end of the water pipe 23; an external water level detection means 50 that is in communication with an upper header 24 and a lower header 22 and detects a water level of the inside and outside of the boiler body; and a control means 100 to control the operation of a water supply means 70 to decrease a water level inside the boiler body 20 if a detected water level by the external water level detection means 50 reaches a first set water level. The boiler includes a header water level detection means 60 for detecting the water level that exists inside the upper header 24 because the boiler water inside the water pipes 23 is forced up by air bubbles produced by the boiling of the boiler water. If the water level detected by the header water level detection means 60 reaches a second set water level, the control means 100 controls the operation of the water supply means 70 to decrease a water level inside the boiler body 20. | ||||||

| PURPOSE: To improve a controller for a water supply flow in a water supply pipe 47 of a steam generator so as to prevent a temperature of steam flowing out of a reheater surface from fluctuating largely and quickly. CONSTITUTION: A controller detects as control parameters steam enthalpy, steam temperature, thermal power transmitted to a tube 4, a ratio of feedwater flow to steam flow in a steam line 11, a ratio of injection water flow into a spray-type super heating reducer in the steam line to the feedwater flow, and residual moisture of steam in the steam line, thereby influencing the feedwater flow correspondingly.

| PURPOSE:To prevent a condenser from being thermally deteriorated by providing a supply water flow rate control circuit on an adjusting valve, and controlling said adjusting valve upon plant emergency to automatically limit water supply for assuring secondary pressure of a cooling water spray valve. CONSTITUTION:A supply water flow rate control device 27 is electrically connected to an adjusting valve 13 for a supply water flow rate. Upon plant emergency, a switching contact 26a is switched to the position of a chain line by an external signal 25, whereby an output from a limit level setting unit 24 is input into a deviation unit 21. Thereupon, said setting unit 24 has been set to a lower level than that of an ordinary level setting unit 19, so that an adjusting unit 22 is operated to close the adjusting valve 13. Hereby, supply water to be introduced into a waste heat recovery boiler 6 is automatically limited, whereby cooling water of prescribed pressure is injected into a cone- shaped temperature reducing unit 16 via a cooling water spray valve 18 without reducing the head of a water supply pump 11. Thus, any vapor flowing in, from a bypass tube 14 is cooled to prescribed temperature, whereby a condenser 10 is prevented from being thermally deteriorated. | ||||||

| PURPOSE:To reduce the influence given to a water supply system due to transient phenomena, by controlling a boiler water supply pump recirculating valve, in case when a load of a turbine generator is decreased suddenly in a heat power plant. CONSTITUTION:In case when first cut-back (FCB) suddenly decreasing a load of a turbine generator is executed, an FCB command signal is given to a boiler water supply pump recirculating valve (BFP). An output load is decreased instantaneously by the FCB command signal, and is held to a low load output. Since the FCB command signal is also provided to the BFP, too, the BPF is opened forcibly. As a result, overheat of the pump caused by a decrease of the flow rate is prevented, and a very stable and smooth control is executed. | ||||||

| The invention relates to a method for regulating the production of steam (16) from feed water (10) in an evaporator (6) of a steam plant. A state regulator (30) calculates a plurality of states of a medium in the evaporator (6) by means of an observer (42) and, on the basis thereof, determines a feed water mass flow rate (ms) as a regulating variable. In order to obtain a stable and precise regulation of the temperature of the steam, the state regulator (30) is a linear-quadratic regulator. | ||||||

The method additionally includes determining (104), via the processor (39), a measured flow rate of the fluid. The method further includes determining (106), via the processor (39), a variable multiplier based at least in part on the commanded fluid flow rate and the measured flow rate; and deriving (108), via the processor (39), a multiplied flow rate command for the industrial system (10) by applying the variable multiplier to the commanded fluid flow rate.

| [Problem] To provide a condensate flow rate control device and control method for a power plant that improve responsiveness to frequency fluctuations or requested load changes, that can reduce frequency fluctuations with precision, or that can improve the precision with which the output power conforms to requested load instructions. [Solution] A power plant equipped with a condensate flow rate control device (36) is provided with a deaerator (32) into which condensate generated in a condenser (26) is supplied via a deaerator water level adjustment valve (34) and into which the bleed steam from a steam turbine (18) is introduced. The condensate flow rate control device (36) has a water level adjustment means (40) for conducting condensate flow rate control. The water level adjustment means (40) adjusts the pressure in the condensate flow path from the deaerator water level adjustment valve (34) to the deaerator (32) so that input frequency fluctuations are suppressed, or so that the output value of a generator (12) conforms to input requested load changes, thereby adjusting the amount of bleed steam from the steam turbine (18). | ||||||
