Title: Condensing boiler for heating with a heat-conveying liquid
Inventor: KERAUTRET ANDRE
IPC: F24H1/44
Filed: 1989-11-24
Granted: 1998-12-15
Abstract: The invention relates to a condensing boiler for heating with a heat-conveying liquid, comprising an inverted burner (1) in the top part of the boiler above a heat exchanger (2) in which the heat- conveying liquid circulates and which is formed from a plurality of interconnecting stages, each stage having one or more tubes (A to N), so as to form a liquid-circulation length which increases moving upwards from one stage to the other, while the inlet (21) for the liquid to be heated is connected to the bottommost stage, and the outlet (22) for the heated liquid is connected to the uppermost stage, and a collection chamber (3) for the condensates and the combustion gases is arranged beneath the said exchanger (2). The boiler according to the invention is notable in that the stages interconnect such that the flow of the heat-conveying liquid is split, relative to the flow supplying the boiler, in at least some of the tubes of at least some of the stages furthest from the burner, whereas the flow is situated in its entirety in all the tubes (J to N) of at least the stage closest to the burner. <IMAGE>

Title: Circulation type fluidized bed boiler
Inventor: OUSHITA TAKAHIRO
IPC: F22B31/00
Filed: 1989-12-29
Granted: 1999-11-15
Abstract: This invention relates to a composite circulation fluidized bed boiler. A fluidized bed portion of the fluidized bed boiler is divided by a partition into a main combustion chamber and a heat recovery chamber, and at least two kinds of air chambers, i.e. an air chamber for providing a large fluidizing speed to a fluidization medium and an air chamber for providing a small fluidizing speed are provided. The combination of air having different fluidization speeds and jetted from these air chambers generates a swirling circulation flow in the fluidization medium inside the main combustion chamber and a circulation flow of the fluidization medium is generated between the main combustion chamber and the heat recovery chamber. Inside the heat recovery chamber, heat recovery of an exhaust gas is made at a free board portion or downstream of the free board portion in an internal circulation fluidized bed boiler for lowering the fluidization medium in the form of the fluidized bed, and after the temperature of the exhaust gas is lowered, the exhaust gas thus cooled is led into a cyclone and the char in a fine particle form collected by the cyclone is returned to the portion immediately above, or into, the lowering moving layer of the fluidization medium in the main combustion chamber and/or the heat recovery chamber. Since the char is returned immediately above or into the lowering moving layer of the fluidization medium, it does not immediately scatter to the free board portion. Accordingly, though it is the fine particles, it sediments and diffuses sufficiently into the fluidized bed so that NOx generated by the combustion of coal or the like inside the layer can be reduced.

Abstract: 본 발명은 용탕재료가 브리지상태로 되어 가열을 지속함으로써 유도로벽이 손상을 받는 것을 미연에 방지할수 있는 유도로의 브리지보호장치에 관한것으로서, 본 발명에 따른 장치는 유도체의 용탕재료가 브리지상태로되어 용탕온도가 상승하는 상태에 대해 유도체를 구성하는 내화재료의 내부에 매입된 온도센서에 의해 검출하고, 이 온도센서를 용탕누설검출용 안테나에 접속하여 용탕누설사고도 겸해서 검출한다. 또, 용탕온도에 대응하여 유도로 코일의 교류전력에 대한 각종전기데이타(전압·전력·주파수)가 변화하므로, 이 전기데이타의 시간적인 변화정도로부터 용탕재료가 브리지상태인가의 여부를 판정한다. 또한, 유도로의 운전진행에 대응한 상기 전기 데이타의 변화를 미리 데이타기억수단에 기억시켜 조업중의 유도로로 부터 검출하는 전기 데이타와 이 기억수단의 전기데이타를 비교하고, 양자의 편차가 일정시간계속하여 소정치보다 크면 경보를 발한다.

Title: Valve control device for vacuum booster
Inventor: BAEK WOON-TAE
IPC: B60T13/52
Filed: 1993-10-09
Granted: 1996-09-04
Abstract: The valve control device for vacuum booster controlls the opening rate of the valve. A plunger valve(90) formed at an end of input shaft(14) corresponds to the disk relaxation(16) combined to the push rod(10). The poppet retainer(20) and the spring retainer(20) support a spring(18) fitted to the input shaft. A control valve(24) equipped with a spring retainer is installed on the valve body(26). The valve body is built in the booster(32) comprising a front shell(28) and a rear shell(30) to build a vacuum chamber(34) and a pressure changing chamber(36). The opening rate of the vacuum valve is almost zero when the vehicle stopped by the brake and the opening rate is full at the returning stage.

Title: Receiver cutout circuit of transcluck
Inventor: CHOE SONG-CHOL
IPC: H04L7/033
Filed: 1993-10-25
Granted: 1995-10-06
Abstract: The instantaneous reference clock signal transmission fail caused by a transmission clocking switching action is protected by the circuit. The circuit includes a state control circuit(37) for controlling input terminal selection and for generating clock selection control signal and frequency divide control signal, a clock selection circuit(35) for selecting output clocks of first and second band pass filters(31,32), and a reference clock generator(36) for providing reference clock signal to a PLL unit.
