Title: Fine powder coal combustion method
Inventor: SUWA TOSHIO
IPC: F23D1/00
Filed: 1985-11-15
Abstract: PURPOSE:To enable a combustion of fine powder coals at less energy cost to be performed by a method wherein each of auxiliary combustion gas containing concentration of oxygen of more than a specified value and fine powder coals are preheated to a specified temperature and the fine powder coals are ignited with the auxiliary combustion gas. CONSTITUTION:In a burner for an electric furnace for melting scraps and a melting furnace for aluminum and copper etc.,when an auxiliary combustion gas and fine powder coals are preheated and the fine powder coals are ignited with the auxiliary combustion gas, if T = auxiliary combustion gas temperature ( deg.C), C = concentration of oxygen in the auxiliary combustion gas (%) and t = temperature of fine powder coals ( deg.C), an equation of T>= exp{14.14-1.84lnC-exp(0.01127t-3.444)}, where t<=300 deg.C and C>=30%, a combustion is carried out to fulfill this condition. When the fine powder coals are preheated to above 300 deg.C, low temperature tar is extracted and a feeding or transportation of fine powder coals becomes difficult. When the combustion is performed with an exclusive fine powder coal burner in a range of a preheating temperature of fine powder coals of a maximum temperature of 300 deg.C, a concentration of oxygen in the auxiliary combustion gas of more than 30% and a preheating temperature of auxiliary combustion gas of more than 80 deg.C, a flame of more than bout 2,000 deg.C can be formed. With this arrangement, it is possible to ignite fine powder coals at less energy cost.

Title: Intake device for gas turbine
Inventor: NAGAE MASAHIRO
IPC: F02C7/08
Filed: 1992-09-25
Abstract: PURPOSE:To provide a intake device for a gas turbine to suppress the lowering of fuel consumption throughout a whole operation area and perform maintenance of combustion efficiency at a high value. CONSTITUTION:Air compressed by a compressor CP is heated by a heat- exchanger HX by means of exhaust gas. A heat-exchanger is divided into primary and secondary flow passages 111 and 112 and intake air passing the primary flow passage 111 is fed to a combustor CC through a primary intake air hole CC1 and intake air passing through the secondary flow passage 112 is fed thereto through a secondary intake air hole CC2. Distribution of a flow rate of air flowing through the first and secondary flow passages is controlled through opening and closing of a moving partition plate 100. During low load operation, the temperature of the primary intake air is increased through the decrease of a flow rate of intake air flowing through the primary flow passage 111 by throttling the moving partition plate. During high load operation, the moving partitioning plate is brought into an opened state and flow rates of air passing through the two flow passages are made equal to each other. This way causes maintenance of combustion efficiency at a high value and suppression of worsening of fuel consumption.

Title: Combustion controller of space heater
Inventor: SEKIYAMA YOSHIO
IPC: F23N5/02
Filed: 1986-10-28
Abstract: PURPOSE:To shorten the time up to hot air delivery when the room temperature is high by computing a time span limiting the quantity of a fuel supplied at the initial time of ignition according to the room temperature and to limit the quantity of the fuel supplied until the thus obtained time passes to a small quantity, in the title device for use in an automobile. CONSTITUTION:Before the ignition of the space heater an electronic controller 40 receives a signal from a room sensor 34 and computes a required time t1 of an ignition mode corresponding to a room temperature T0 by a predetermined equation I. Then, a fuel pump 15 is turned on, and the fuel is sent to a vaporizing chamber and power is supplied to an ignition glow plug 17 and a vaporizing glow plug 16. Simultaneously, the supply quantity of the fuel is reduced to a predetermined fuel supply quantity in the ignition mode. At this time, the electronic control unit 40 starts timing from the ignition time. When the timing passes the ignition mode time t1, the electronic control unit 40 switches the mode to a fuel supply corresponding to a desired space heating position. By this construction, the time until a hot air flow is delivered when the room temperature is high can be shortened.

IPC: H04M15/04
Filed: 1988-10-14
Abstract: PURPOSE:To easily perform the calculation of a call charge based on charge data before that time by calculating the call charge at every subscriber by performing exact calculation and an estimation processing based on the charge data read out from a charge data accumulating means. CONSTITUTION:A charge data transfer device 4 receives all data blocks outputted from a central control unit 11 to an external memory device 13 by an input/output control part 41. And the charge data with respect to the call of a short term subscriber is identified based on identification data attached on the charge data by an identification and edit control part 42, and it is edited to data for call time and the frequency of call at every subscriber. After that, the charge data is transferred to a short term subscriber call charge accounting device 5 by an input/output control part 43 via a line 6. Thus, since the amount of data to be transferred can remarkably be reduced by taking a mode to transfer only the charge data with respect to the short term subscriber, the processing capacity of the data transfer device 4 can be set easily. Also, the capacity of the line 6 can be reduced.
