Abstract:
Disclosed is a decoratively illuminating apparatus using a candle including a candle, a light transparent holder, and a light transparent accommodating seat held in the holder while accommodating the candle. The candle (100) includes a candle body (20), a flammable wick (30) fixed in the center of the candle body (20), and a light transmission line (40) arranged along the flammable wick around the center of the candle body and fixed such that a lower end of the light transmission line is exposed from the lower side of the candle body. The holder (200) includes a bore (210) formed in a top side (201) as a light radiating space, and a light radiating unit (260) having a photosensor (245) to detect light of the flammable wick (30) through the light transmission line (40) and a light source (222) electrically connected to the photosensor (245).
Abstract:
A combustion apparatus comprising a pre-combustor stage and a primary combustion stage, the pre-combustor stage having two co-axial cylinders, one for oxidant and one for fuel gas, in which the fuel gas is preheated and the primary combustion stage having rectangular co-axial passages through which fuel and oxidant are admitted into a refractory burner block. Both passages converge in the vertical plane and diverge in the horizontal plane. The passage through the refractory burner block also has a rectangular profile and diverges in the horizontal plane. The outlets to the primary combustion stage are recessed in the refractory burner block at a distance which may be varied.
Abstract:
The oblique bed wall (6) of the furnace main unit (1) is inclined in downward direction towards the ash discharge outlet (5). Oblique side walls (24R, 24L) are formed in the right and left side walls (1c, 1d) on the inlet (4) side of the furnace main unit (1), and fluidized bed material (S) blown up from the side fluid layers (RS, LS) is guided into the central fluid layer (CS). The fluidized bed material (S) is caused to circulate in succession from the central fluid layer (CS) at the inlet (4) side towards the central fluid layer (CS) at the ash discharge outlet (5) side towards side fluid layers (RS, LS) at the ash discharge outlet (5) side towards side fluid layers (RS, LS) at the inlet (4) side towards central fluid layer (CS) at the inlet (4) side, by dispersive air emitted from dispersive air pipes (21A, 21B, 25). In this way, the fluidized bed material (S) is caused to circulate in virtually a horizontal plane without partitioning walls. Slow combustion is conducted due to a slow fluid speed, particularly in the drying and pyrolyzing zone. Stable combustion is achieved, and generation of carbon monoxide and dioxin is suppressed.
Abstract:
The invention is intended to suppress oscillatory combustion of a combustion apparatus. In the invention, acoustic closed ends are provided at an inlet side and an outlet side of the burner port unit, and the combustion apparatus is constituted so that the flame may be positioned between these closed ends, and a buffer chamber is provided at the inlet side. Thus, when the inlet side and outlet side of the burner port unit of the combustion apparatus are formed as acoustic closed ends, oscillatory combustion occurs easily. At this time, when the intake tube communicates at the upstream side of the inlet side closed end, and an exhaust tube communicates at the downstream side of the outlet side closed end, if the length of the intake tube and exhaust tube is changed, the air ratio and combustion amount for generating oscillatory combustion remain constant, and the oscillation frequency and oscillation pressure remain constant. In such condition, when a sound absorbing unit is provided in the buffer chamber, oscillation does not occur, and if the intake tube or exhaust tube is extended, oscillation does not occur.
Abstract:
This invention is both a partial combustion process in which the fuel is partially combusted using specific catalysts and catalytic structures and also a catalyst structure for use in the process. The choice of catalysts and supports solves problems in the art dealing with the stability of the overall catalyst structure and ease of catalyst operation. The catalyst structure is stable due to its comparatively low operating temperature, has a low temperature at which catalytic combustion begins, and yet is not susceptible to temperature "runaway". The combustion gas produced by the catalytic process typically is below the autocombustive temperature for the gas mixture; the gas may be used at that temperature, or fed to other combustion stages for ultimate use in a gas turbine, furnace, boiler, or the like.
Abstract:
A Coanda flare having an outlet adapted to direct high pressure fuel gas over the director surface of the Coanda body so as to entrain surrounding air into the fuel gas flow. A water injection nozzle is located upstream of the outlet and located within the high pressure fuel gas supply line. By injecting water into the fuel gas prior to its emergence from the outlet, a flare having reduced noise and radiation characteristics is achieved.
Abstract:
A burner for a cooking grill has upper and lower sections which are joined together to enclose a plenum for containing a combustible gas. The lower section has a peripheral wall containing apertures which enable the gas in the plenum to escape for burning outside of the burner. In addition, the lower section has a bottom wall provided with a hole, while the top section has a top wall provided with a recess located opposite to the hole. A short inlet tube, to which the combustible gas is supplied, extends through the hole in the bottom wall, and within the plenum segments of the tube are bent outwardly away from the tube axis in the form of tabs which overlie the inwardly presented surface of the bottom wall. These segments leave the tube with openings that permit gas to flow from the tube to the plenum. The remaining tube segments of the inlet tube extend into the recess of the top section, so that the tube is captured firmly between the two burner sections, and these segments are presented toward the plenum apertures which are closest to the tube to prevent an excessive amount of gas from flowing to those apertures.
