20110318697 | GROUND FLARE - Provided is a ground flare in which a low-frequency vibration generated from a ground flare tower, such as a chimney, is properly adjusted to suppress it below a fixture-vibration generation limit, thereby preventing surrounding objects from resonating and vibrating. In a ground flare that burns a flammable exhaust gas with a burner at the lower end of a chimney, in which the lower end of the chimney and the periphery of the burner are surrounded by a windbreak, the low-frequency-noise sound pressure level of a ground flare tower composed of the chimney and the windbreak is reduced by selecting at least one of changing a natural frequency generated from the ground flare tower, using multiple ground flare towers, and installing a low-frequency-vibration absorber in the ground flare tower. | 12-29-2011 |
20130298465 | PULVERIZED-COAL SUPPLY SYSTEM FOR COAL GASIFICATION FURNACE - To provide a pulverized-coal supply system for a coal gasification furnace in which the consumption of inert gas (the amount used) can be reduced. The pulverized-coal supply system is equipped with a pulverized-coal supply hopper ( | 11-14-2013 |
20140237986 | SLAG DISCHARGE SYSTEM, GASIFIER, AND GASIFICATION POWER GENERATION APPARATUS - A slag discharge system that includes: a gasification furnace which thermally decomposes and gasifies a pulverized raw material composed of a carbonaceous solid; a slag hopper which is provided at a bottom portion of the gasification furnace and receives slag produced from the pulverized raw material and in which cooling water is stored; a lock hopper which temporarily stores the slag outside of the gasification furnace; and a slag discharge line which makes the slag hopper communicate with the lock hopper. The lock hopper is disposed to the side of the gasification furnace, and the slag discharge system is provided with a water flow forming apparatus for forming a flow of the cooling water which allows the slag to be led to the lock hopper in the slag discharge line. | 08-28-2014 |

20120196241 | SLAG DISCHARGING SYSTEM - There is provided a slag discharging system having high flexibility in layout and capable of stable slag discharge in low cost with high reliability. The slag discharging system is configured to rapidly cool slag, discharged by producing combustible gas in a gasification furnace, within cooling water into glassy slag, collect the slag along with the cooling water discharged out of a system of the gasification furnace into a slag reservoir, and thereafter convey the slag from the slag reservoir to a slag storage tank; and this slag discharging system includes a slag slurry tank for collecting the slag from the slag reservoir into water so as to make the slag into slurry therein, slag slurry piping for making a connection between the slag slurry tank and the slag storage tank, and a pump so disposed in the slag slurry piping as to suck the slag slurry within the slag slurry tank and feed the slag slurry to the slag storage tank. | 08-02-2012 |
