Abstract: The present invention provides a hydrolysate of a lignocellulosic material, and specifically a method of using a hydrolysis treatment liquid obtained by a hydrolysis treatment of a lignocellulosic material before kraft cooking in order to obtain dissolving pulp for uses other than use of a fuel. Specifically, the present invention provides a dispersant containing the hydrolysate obtained by hydrolysis treatment of the lignocellulosic material. The dispersant of the present invention has excellent dispersibility for a substance such as an inorganic substance and an organic substance without limitation of powder, particulate, granular, fiber, and flat plane shapes.

Abstract: A steam valve control device of this embodiment controls a steam valve. The steam valve has: an upper cover in whose through hole a bush is installed; and a valve rod which is installed so as to penetrate through the through hole of the upper cover via the bush. The valve rod has a contact surface which is formed so as to come into mechanical contact with the bush when the steam valve is opened to a maximum opening degree. The steam valve control device has a control part. When a governor free operation is performed, the control part controls the steam valve by setting a limited opening degree limited to be smaller than the maximum opening degree as an upper limit. When a load limiter operation is performed, the control part controls the steam valve by setting the maximum opening degree as the upper limit.

Abstract: The steam valve driving device of this embodiment adjusts a flow rate of steam flowing inside a valve box by varying a distance between a valve seat and a valve element connected to a valve stem in the valve box. The steam valve driving device has an oil cylinder and a spring box. Here, an inlet and an outlet are formed in the spring box. Then, the air from the outside of the spring box is supplied into the spring box from the inlet of the spring box so as to make a pressure in the spring box higher than that of the outside, and is discharged from the outlet of the spring box.

Abstract: A high temperature steam valve has a valve casing including a main steam inlet, a main steam outlet and a valve chest. The high temperature steam valve also has a valve seat positioned in the valve chest, a valve element facing the valve seat, and a valve rod slidably penetrating the valve casing to drive the valve element. A cooling steam hole is provided to surround a valve-rod penetrating portion of the valve casing. Cooling steam can be poured into the cooling steam hole from outside through a cooling steam inlet hole and steam having finished heat exchange can be exhausted from a cooling steam outlet hole into the valve chest. The sliding portion between the valve rod provided in the valve-rod penetrating portion of the valve casing and bush is cooled to prevent oxidized scale from depositing on the sliding portion.

Abstract: Cause of abnormalities of an abnormal state of a control system of a plant of a turbine are estimated and diagnosed from characteristics of abnormal phenomena. By using a control system abnormality cause-and-effect matrix in which characteristics of a plurality of abnormal phenomena constructed on a knowledge base are correlated with a plurality of causes by correlating (weighting) scores, plant devices causing abnormality are inferred and diagnosed.
