    摘要: A spectrum analysis camera (300) which can, by itself, deliver both an ordinary color picture and a picture for spectrum analysis and a spectrum analysis system. In the CCD (charge-coupled device) section of the camera (300); one photosensitive unit is constituted by n (at least two) photosensors (S₁-S₉). The n photosensors (S₁-S₉) are set so as to have detection wavelength ranges which do not overlap each other. The spectrum analysis is performed using the output signals of the individual photosensors (S₁-S₉) in Fig. 3(b). On the other hand, the color picture is formed using R (red); G (green) and B (blue) signals which are created by synthesizing the output signals of the respective photosensors (S₁-S₉).

    摘要: A combustor has a premixing type combustion burner (30) which has an atomizer (40) for ejecting a liquid fuel together with combustion air to atomize the liquid fuel. The atomizer is comprised of an inner shell (45) to an inner peripheral surface of which the liquid fuel is supplied, an outer shell (41) defining a passage for the combustion air running substantially straight between the outer shell itself and an outer peripheral surface of the inner shell, and a swirling-flow guide plate (50) for swirling the combustion air passed into the inner shell, while directing it in a downstream direction. The combustor further includes a resistor (35) abruptly decreased in sectional area downstream and provided substantially downstream of the center of the swirling flow and in the vicinity of an outlet of the premixing type combustion burner for providing a resistance to a premixture ejected from the premixing type combustion burner.

    摘要: A low-NOx boiler comprises a burner for burning gaseous fuel, heat transfer pipes (117) heating water by combustion heat of the burner to generate steam and having a passage (131) through which water flows, a steam drum (128) communicating with the heat transfer pipe and accumulating the steam from the heat transfer pipe, and an exhaust gas duct (114) located in the furnace to exhaust combustion gas generated by combustion of gaseous fuel outside of the boiler. The boiler further comprises unburnt gas burner (126) in the exhaust gas duct (114) for burning unburnt content in the combustion gas flowing in the duct. The unburnt gas burner includes a nozzle (2) for inject­ing premixture flow of fuel and combustion air and flame holding plate (1) located near the downstream side of the outlet of the nozzle to interrupt the premixture flow to form a circulating flow on downstream side of the flame holding plate. As gaseous fuel and air are mixed in advance and a flame is formed, the flame length can be shortened. Furthermore, the flame holding plate enables to reduce NOx generated. Unburnt gas burner pro`vided in the exhaust gas duct makes it possible to notably reduce the concentration of NOx discharged to the outside of the system.
