Title: Smelting and reduction iron making method
Inventor: NAKAMURA HIDEO
IPC: C21B11/08
Filed: 1986-02-10
Abstract: PURPOSE:To produce a molten iron from ore with high thermal efficiency by blowing preliminarily reduced iron ore, coal, lime and oxygen from bottom tuyeres to a furnace of a top blown converter system having the bottom tuyeres and blowing oxygen with a top blowing lance having rotary vanes. CONSTITUTION:The molten iron 6 of a seed melt is first put into the furnace 2 of the top blowing converter system having a rotary lance 9 provided with the stirring vanes 10 and the plural tuyeres 3, 4 at the bottom. The preliminarily reduced iron ore having <=0.5mm grain size and powder of the coal and lime are blown by a process gas as a carrier gas from the bottom tuyeres 3 into the molten iron 6 in the furnace. Gaseous O2 is blown from the tuyeres 4 at the same instant and while foaming slag 7 is stirred by the lance 9, the gaseous O2 is blown. The iron ore is reduced by the coal and at the same time the gaseous CO is generated which is burned to CO2 in a secondary combustion zone 8 by the gaseous O2 from the lance 9 to generate heat. The sensible heat of the high-temp. CO2 is transferred via the foaming slag 7 to the molten iron 6 to heat the molten iron. Since an exhaust gas is relatively low in temp. and is discharged from the throat, the erosion of throat bricks by the heat of the exhaust gas is prevented.

Abstract: PURPOSE:To lighten the burden of a microcomputer for forming a synchronizing clock, and also, to improve the accuracy of a synchronizing clock signal by generating two kinds of pulses by a simple circuit constitution using one piece of counter and using these two kinds of pulses for serial communication between plural microcomputers. CONSTITUTION:A counter 1 counts a clock of a prescribed period, and a comparator 2 generates a first pulse (period T1') at the time of coinciding with a set value of a memory 3, and clears the counter. A set value updating circuit 6 sets an initial value to a memory by the generation of the first pulse, and a comparing circuit 4 outputs a second pulse, when a value of the counter 1 coincides with the set value. By the set value updating circuit 6, an interval of the second pulse continued from a period T2' and the first pulse is also set to T2'. By the first pulse of a long period, a transfer time of an information block group in serial communication is prescribed, and by the second pulse of a short period, a transfer time of an information block in the group is prescribed. According to this constitution, the burden of a microcomputer is decreased, and the accuracy of a synchronizing clock is improved.

IPC: F23C99/00
Filed: 1988-02-09
Abstract: PURPOSE:To reduce unburnt portion and NOx even if pulverized coals having different fuel ratios are burnt simultaneously, by a method wherein a burner is provided with a pulverized coal feed passage at least on the innermost side of the burner and with an additional pulverized coal feed passage outside the innermost pulverized coal feed passage. CONSTITUTION:A burner throat 2 is formed on the wall of a furnace 1. Pulverized coal feed passages 4, 6 and air feed passages 3, 5 are provided on a concentric circle at the opening of the burner throat 2. Pulverized coal (low fuel ratio pulverized coal) which is low in the composition proportion of fixed carbon contents with respect to a volatile matter is fed to the innermost side pulverized coal feed passage 6 from the outside pulverized coal feed passage 4 to form a reducing flame in the furnace 1 and, on the other hand, pulverized coal (high fuel ratio pulverized coal) which is high in the composition proportion of fixed carbon contents with respect to volatile matter is fed to the outside pulverized coal feed passage 4 from the innermost side pulverized coal feed passage 6 to form an oxidizing flame in the furnace 1. The high fuel ratio pulverized coal is burnt at high speed due to sufficient air supply to decrease an unburnt portion, and NOx generated is decomposed by the reducing gas generated in the fuel region of the low fuel ratio pulverized coal, whereby NOx is reduced.

Title: Vortex flowmeter
Inventor: TAKAHASHI SEIICHIRO
IPC: G01F1/32
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To enable stable detection of a flow rate by making a vortex signal overlapped with a noise pass through a filter divided in band to remove various noises effectively. SOLUTION: A corner frequency of an LPF 22 is set to the maximum vortex frequency determined by the calibre, the fluid density, the maximum flow rate and the like of a piping. As a result, the noise of a frequency component exceeding the maximum vortex frequency is removed. Among frequency components divided in band, a microcomputer 24 identifies a frequency component, which is the maximum in the intensity of a signal, as vortex frequency component and computes the frequency component by an arithmetic means 24 to calculate a flow rate. As for spike noises, the intensity of signals in respective bands are measured at each computing cycle by a moving average of the noises to judge that the noises are not stationary signals. The number of division stages is four here but other than four is possible.  Thus, the vortex signal overlapped with the noises is divided in terms of band by a band division filter to extract a frequency component to remove various noises effectively thereby enabling stable detection of a flow rate.
