Title: Combustion controller for low pressure boiler
Inventor: NAKAI YASUJIRO
IPC: A47J27/04
Filed: 1996-08-20
Abstract: PROBLEM TO BE SOLVED: To prolong the life of parts and save energy by making it possible to input to a combustion controller whether or not vapor is supplied to a vapor using apparatus, and making the combustion controller start combustion of a burner when vapor pressure is not more than a lower limit pressure and vapor is being supplied to the vapor using apparatus. SOLUTION: When operation starting is inputted to a combustion controller 7 when a low pressure boiler 1 is subjected to an initial starting, the combustion controller 7 confirms that vapor pressure detected by a pressure detector 5 is not more than a lower limit pressure to start combustion of a burner 6. A timer 14 outputs a preheating completion signal to the combustion controller 7 once starting lapse time exceeds a predetermined preheating time. The combustion controller 7, once the preheating completion signal is inputted, is brought to combustion control based upon the vapor pressure and vapor using conditions, and the combustion of the burner 6 is started only when the vapor pressure is lower than the lower limit pressure and a vapor supply control valve 3 is opened. Hereby, the number of times of combustion of the burner 6 is reduced and unnecessary combustion is prevented.

Title: Chrominance signal processing device
Inventor: MATSUMOTO TOKIKAZU
IPC: H04N9/83
Filed: 1983-12-16
Abstract: PURPOSE:To obtain always an accurate axis of demodulation and constitute a comb line filter into a semiconductor and make it small-sized by using information of a burst part of the R-Y axis as a control voltage of a voltage control oscillator (VCO) which operates an A/D converter and a demodulator. CONSTITUTION:A reproduced signal obtained from a reproducing head 30 passes an amplifier 31, an LPF32, and an automatic signal gain adjuster (ACC)33 to become a low-band conversion chrominance signal having a certain level and is converted to a digital signal by an A/D converter 34. This digital signal is demodulated to a B-Y signal and an R-Y signal by a demodulator 35, and they pass comb line filters 36 and 37 respectively to eliminate crosstalk and are applied to the modulator 38. The R-Y signal of the output of the comb line filter 37 is subjected to D/A conversion and is applied to a burst gate 42, and a burst signal obtained there is applied to a VCO45 through a switch 44 and an LPF46. The output of this VCO45 is used as a reference clock of the demodulator 35 to keep always the axis of demodulation accurate.

Abstract: PURPOSE:To reduce NOx in the discharged gas as an effect of improvement of baffling of a flame by providing an auxiliary fuel-gas nozzle upstream in a passage for primary air and a premix-burning flame baffle for preliminarily mixing auxiliary fuel gas and primary air at the forward end of an inner cylinder. CONSTITUTION:Fuel gas is fed through two separate channels, that is, from a gas-distributing pipe 18 and from an auxiliary gas-distributing pipe 29. The auxiliary fuel gas and primary air are preliminarily mixed inside a premix- burning flame baffle 31; accordingly, the auxiliary fuel gas from auxiliary fuel- gas nozzles 30 is prepared into a premix in a primary air passage 21. The main fuel gas is ejected from main fuel-gas nozzles 32 and the air for its combustion is fed into a boiler furnace 3 through the primary, a secondary, and a tertiary air passages 21, 22, 23. For the main fuel gas each of gas elements 14 is wrapped around with an inactive gas of low O2 concentration. For this inactive gas part of the exhaust gas is fed into an exhaust gas duct 33 and into the boiler furnace 3 through openings between the gas elements 14. The flame produced by main fuel gas according to this method is divided and has a larger cooling area and the method has an effect for reducing NOx.
