Title: Combustion method of pulverized coal, pulverized coal combustion device and pulverized coal combustion burner
Inventor: KOBAYASHI YOSHINOBU
IPC: F23D1/02
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a combustion device which forms stable combustion flames only by the supply of pulverized coal or a pulverized coal combustion burner even under the condition which burns only nonflammable pulverized coal or under a low load condition. SOLUTION: An air nozzle 11, which feeds air in a swirling current, is laid out around the outer periphery of a fuel nozzle 10 which conveys pulverized coal by air. The fuel nozzle 10 forms a first recirculating current around the edge of the nozzle while the swirling current forms a second recirculating current on the outer periphery of a fuel jet, and forms a third recirculating current 22 in the peripheral direction of the second recirculating current 21 and the current 22, which is partially formed integrally with the first recirculating current 20. Since the third recirculating current 22 feeds a high temperature gas of the second recirculating current 21 to the fuel nozzle, it is possible to enhance the stability of flames of pulverized coal.

Abstract: PURPOSE:To reduce change in an interval in the axial direction between a gear and a bearing by providing a differential thermal expansion reducing member between a pump case and the bearing on the side of a shaft end. CONSTITUTION:A differential thermal expansion reducing member 15 is interposed in an interval in the axial direction between a bearing 7 of a gear pump 1 and a first pump case 2b.

Title: Continuously measuring method for concentration of nitrogen monoxide in gas
Inventor: IKUNO HIROSHI
IPC: G01N21/3504
Filed: 1990-11-27
Abstract: PURPOSE:To measure continuously the concentration N2O in an exhaust gas with high precision by correcting interference by a coexistent gas by an infrared absorption analysis method. CONSTITUTION:In the case when CO2 and CO coexist in a measured gas, a CO component therein is subjected to oxidation pretreatment to be turned into CO2 under prescribed conditions, then CO2 and N2O are measured simultaneously by an infrared absorption analysis method, and N2O is corrected by using a prescribed correction formula. Correction of an N2O measured value is executed by using a correction curve prepared for each concentration of CO2, and correction curves required are lessened by the absence of combination. The curve in regard to each concentration of CO2 approximates to a straight line in a narrow range. According to this constitution, the concentration of N2O in an exhaust gas can be measured continuously with high precision by the infrared absorption analysis even when coexistent gases are present.

IPC: G11B23/28
Filed: 1989-12-11
Abstract: PURPOSE:To prevent an erroneous erasing preventing valve from dropping upward by engaging the valve to the upper end of an inner deep wall on a lower case side over the lock arm of the erroneous erasing preventing valve. CONSTITUTION:When a lower case 1b is covered with an upper case 1a, on the inner surface of a rear wall 10a of the upper case 1a, one or more than two ribs 30 are integrally protruded and formed so as to be vertically extended from the inner top surface. In the state of coupling the upper and lower cases 1a and 1b, these ribs 30 are positioned so as to be close faced to the upper direction of an erroneous erasing preventing valve 12 even when the valve is set at a recordable position or an unrecordable position. Thus, it is regulated for the valve 12 to be loosely moved upward from an inner deep wall 13 more than needed while being abutted to the lower end of the rib 30. Therefore, even when the valve 12 is pushed up by unnatural force and a main wall 15 tries to go over the inside of the rear wall 10a of the upper case 1a in addition to the bending deformation of the inner deep wall 13 to a case front side at one part, a lock arm 16 of the valve 12 is abutted to the lower end of the rib 30 and interfers the rib 30 and therefore, the upward move is blocked without fail.
