Abstract: A load adjustment method, comprising: a step of acquiring a warm-up parameter indicating the degree of warm-up of a gas turbine during operation under load; a step of determining an upper limit of a load increase rate in accordance with the warm-up parameter; and a step of increasing the load of the gas turbine at or below the upper limit of the load increase rate.

Abstract: A water quality management device is provided with a water quality index value acquisition unit which acquires water quality index values including a makeup water quality index value indicating water quality of makeup water and a circulating water quality index value indicating water quality of circulating water, and a determining unit which determines an amount of concentration control associated with a concentration rate of a circulating water system based on the water quality index values acquired by the water quality index value acquisition unit.

Abstract: A chemical feed control device controls feeding of a chemical into a water system of a plant. A water quality index-obtaining unit obtains a water quality index value for each of a plurality of disruptive factors of the water system. An environmental data-obtaining unit obtains environmental data related to the plant. An operational data-obtaining unit obtains operational data related to the plant. A determination unit determines a feed amount of each of a plurality of chemicals acting on at least one disruptive factor and having components different from each other with respect to the water system based on the water quality index value, the environmental data, and the operational data such that the water quality index value for each of the disruptive factors approximates a water quality target value for each of the disruptive factors.

Abstract: A network device is provided which comprises a lamp display that includes a lamp visible from the outside, and that has a display mode in which the lamp may light up when the network device is powered on, and a non-display mode in which the lamp does not light up when the network device is powered on; and a lamp mode setting module to set the lamp display to the display mode or the non-display mode, wherein when a prescribed condition requiring the user to take note of the lamp is not met within a prescribed time interval in the display mode, the lamp mode setting module sets the lamp display to the non-display mode, and when the prescribed condition is met in the non-display mode, the lamp mode setting module sets the lamp display to the display mode.

Abstract: A multifunctional water injection manifold device for injecting water into a gas turbine combustor for NOx reduction is provided so that draining of the manifold may be done even in a load operation of gas turbine, and reverse flow of high temperature high pressure combustion gas is prevented so as not to cause eruptive breakage of the manifold. An air communication means is provided at the top portion of the manifold (51) for causing the manifold (51) to communicate with the air so that draining of the manifold (51) is done. A pressure type check valve (54) is interposed in branch pipe (6) between the manifold (51) and the combustor (1) so that water is supplied from the manifold (51) into the combustor (1) when differential pressure between the manifold (51) and the combustor (1) reaches a predetermined pressure or more and the water is stopped when the differential pressure is less than the predetermined pressure.

Abstract: A fuel heating apparatus for a gas turbineis provided in which contact of high temperature air and fuel at the time of fuel leakage is prevented so that safety is ensured. The apparatus includes a turbine cooling air cooler of the air cooling type for cooling turbine cooling air and a fuel heater connected to the exhaust side of the turbine cooling air cooler for heating the fuel by the refrigerant air. The turbine cooling air cooler and the fuel heater 4, respectively, form a separate unit so that contact of high temperature air and fuel at the time of fuel leakage is prevented.

Abstract: A poly(phenylene sulfide) resin composition less liable to discoloration and exhibiting excellent ductilities is provided. The composition comprises a poly(phenylene sulfide) resin pre-cured in a non-oxidative, inert gas atmosphere and a fibrous glass reinforcement exhibiting a very low weight loss on heating. The poly(phenylene sulfide) resin has, before curing, a melt viscosity of greater than about 400 poises at 300.degree. C.
