Filed: 1987-02-20
Abstract: PURPOSE:To make particle measurement with high reliability by disposing plural plates which have specular faces on both faces and are provided with a pass window for a light beam at each center in such a manner that the windows are aligned. CONSTITUTION:An aperture 2 is provided on about each center of the plural flat plates 1 both faces of which are finished to the specular surfaces.

Scattered light is generated when gases 4 flow and the dust particles 5 contained in the gaseous flow cross the beam 3. The scattered light is reflected between the specular faces of the flat plates 1 facing each other and emerges from the spacing between the plates 1 to the outside. After the light is condensed by a lens 7, the light enters a photodetector 8. The particle measurement is thus carried out with high accuracy.

Title: Production of coarse-grained hard watergranulated blast furnace slag
Inventor: TOUBOU HIROYUKI
IPC: C04B18/14
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To simply and efficiently produce the hard water-granulated blast furnace slag without requiring any complex equipment by spraying water of a specified temp. on molten blast furnace slag to quench the slag. SOLUTION: In this production that comprises spraying water on blast furnace slag to quench the slag with the water, the slag is subjected to water spray granulation with quenching water of 60 to 80 deg.C, to produce coarse-grained water-granulated slag. However, generally, in the coarse-grained water-granulated slag thus produced, hard water-granulated slag and soft water-granulated slag coexist. Therefore, in order to produce the objective coarse-grained hard water-granulated slag that needs to have a high specific gravity, the ratio of water to slag i.e., the ratio of (quenching water flow rate, (weight (ton) of water)/hr) to (molten blast furnace slag flow rate, (weight (ton) of slag/hr) is adjusted to>=30 to produce hard water-granulated slag having a >=1.35 kg/L mass of unit volume.  At this time, when the water temp. in a water granulation vessel in which water immediately after it is used for water granulation and the water-granulated slag coexist, is >95 deg.C, the amount of generated steam at the time of performing water spray granulation and quenching of the slag, is increased and accordingly, the volume of closed pores in the water-granulated slag after quenching it is increased to decrease the specific gravity in absolute dry condition of the slag and therefore, to decrease the mass of unit volume of the water-granulated slag produced. Thus, a water temp. in the water granulation vessel is preferably <=95 deg.C.

The piston 130 is pushed down by high-pressure combustion gas to take out motive power. High-pressure water is injected into the combustion chamber 140 through a water injection valve 114 in a crankshaft angle position past the maximum combustion pressure at the expansion stroke after warm-up, so that the water is instantaneously evaporated into high-pressure steam by the high-temperature combustion gas, thus increasing the mean effective pressure on the piston 130.
