Provided is a new binary power generation system that, in the binary power generation system using exhaust gas as a heating source, maximizes the power generation amount while considering the sulfuric acid dew point temperature of the exhaust gas. In this binary power generation system, corrosion due to sulfuric acid is prevented. Provided is a binary power generation system including a binary power generation apparatus that generates power by vaporizing a power generation medium using heat of exhaust gas output from a drive apparatus, wherein the binary power generation apparatus includes a control section that controls a mass flow rate of the power generation medium based on at least a sulfur concentration of the exhaust gas.

Binary power generation system and control apparatus

An amount of seawater control device controls an amount of seawater supplied to a scrubber that purifies sulfur oxide contained in exhaust gas by bringing the sulfur oxide into contact with seawater. The control device includes a minimum amount of seawater converter which calculates a minimum amount of seawater necessary for an absorption reaction of the sulfur oxide by the seawater, an amount of seawater correction converter which calculates a corrected amount of seawater which is an amount of seawater at which the sulfur oxide contained in the exhaust gas discharged into atmosphere from the scrubber is equal to or less than a set variable, a summing element which calculates a set amount of seawater by summing the minimum amount of seawater and the corrected amount of seawater, and a pump control device which implements control such that seawater corresponding to the set amount is supplied to the scrubber.

An exhaust gas treatment apparatus and method that absorbs gas by bringing the gas and a liquid into contact with each other has a plurality of scrubbers that each include an absorption tower main unit in which an internal space is formed. A spray apparatus sprays liquid in a predetermined vertical region of the internal space, and a gas supply apparatus introduces the gas into the absorption tower main unit. A number of first passages branch from a pipe supplying the liquid to the exhaust gas treatment apparatus and are connected to the spray apparatuses of the scrubbers. A number of second passages branch from a pipe supplying the gas to the exhaust gas treatment apparatus and are connected to the gas supply apparatuses of the scrubbers.

A fuel cell power generator having an output controlling system for preventing the deterioration of the fuel cell performance caused by fuel gas shortages. The fuel cell power generator includes a fuel reformer, a fuel cell, an inverter, and an output controlling system. The output controlling system includes an output control regulator for controlling the output power of the inverter as close to the current value corresponding to the output power set value as possible, a current command computing unit, an inverter controller, and an output correction section. The output correction section includes an available output computing unit for computing the maximum available output power value of the fuel cell on the basis of the detected flow rate of fuel gas flowing into the fuel cell or fuel exhaust gas flowing out of the fuel cell; a low level selector for selecting either the computed maximum available output power value or the output power set value, whichever is the lower; and an output correction regulator for supplying the output control regulator with a signal for correcting the output power set value so as to control the detected output current from the fuel cell as close to the current value corresponding to the output current value of the low level selector as possible.
