本発明はコークスの顕熱を回収するコークス乾式消火設

蒸気を発生させる熱回収システムと表っている。(Prior art) As described in Japanese Patent Publication No. 5B-2993, sensible heat recovery from red-hot coke is carried out by charging red-hot coke from above into a vertical furnace, and from below, circulating gas at around 9150°C is used. (N
The coke is extinguished and cooled by blowing in gas (rich gas) and causing the coke and gas to flow counter-currently, and the sensible heat of the coke is reduced to 90%.
It is described as a heat recovery system in which the heat is recovered as hot gas at around 0°C, and nine boilers are installed in the latter stage to generate steam.

集塵機で捕集し工いる。特に−次集塵機で捕集される。The high-temperature circulating gas exhausted from the vertical furnace in this process contains a large amount of coke powder, so a primary dust collector is installed at the outlet of the vertical furnace and a secondary dust collector is installed in front of the circulating gas blower to collect the coke powder. It is being removed. In addition, a bag dust collector is used to collect coke powder generated during charging and discharging coke into the vertical furnace and during coke transport. In particular, it is collected by a secondary dust collector.
赤熱コークス粉の消火冷却処理は、一般に技術的な問題
が多々ろシ、さらにコークス粉の搬送貯留設備を別途膜
けなければならないので、多大の設備費を要する欠点も
ある。The extinguishing and cooling treatment of red-hot coke powder generally has many technical problems, and also has the disadvantage of requiring a large amount of equipment cost because it requires separate coke powder transportation and storage equipment.
一方、他のコークス製造過程でも、大量のコークス粉が
発生するため、コークス粉そのものが現行の生産体制で
は余剰気味である。このため乾式消火設備で捕集される
コークス粉を回収することは、前記の設備上の問題もあ
って必ずしも有益なものでなく、糸外に排出させないよ
うにすることが１１題であった。On the other hand, since large amounts of coke powder are generated in other coke manufacturing processes, the coke powder itself is in surplus under the current production system. For this reason, recovering the coke powder collected by the dry fire extinguishing equipment is not necessarily beneficial due to the above-mentioned problems with the equipment, and the problem was to prevent it from being discharged outside the string.

ものである。(Means for Solving the Problems) The gist of the present invention is to cool high-temperature coke with circulating gas, remove combustibles from the circulating gas after cooling the coke in a dust collector, and use a heat exchanger to remove combustibles from the circulating gas. In a dry fire extinguishing system designed to recover heat, the combustibles collected by the dust collector are burned in a fluidized bed, and a combustion device consisting of an air nozzle eccentric from the furnace core is installed on a freeboard above the fluidized bed. , the unburned materials scattered from the fluidized bed and air are rapidly mixed and combusted, a part of this combustion heat is recovered by water-cooled pipes arranged in the fluidized bed and freeboard, and the remaining hot gas is sent to a heat exchanger. A part of the cold circulating gas is mixed in the high temperature circulating gas flow path before entering the heat exchanger, and a part of the cold circulating gas after leaving the heat exchanger is
The furnace temperature is controlled by blowing air into the fluidized bed combustion furnace.

の凝灰や燃焼が消火する等のトラブルが生じる。(Function) The coke powder collected in the coke dry extinguishing equipment is mostly fine particles of less than 10 tm and is easily scattered during the fluidized bed combustion process, but if an appropriate fluidization state is secured, the combustibility is extremely low. it was good. Since the combustion temperature in the fluidized bed at this time is extremely high, the temperature of the fluidized bed must be controlled to prevent troubles such as clumps of combustion ash and generation of large amounts of NOx. In order to keep the fluidized bed temperature within the appropriate 1/2 range,
Although heat is removed by the water-cooled wall of the fluidized bed, the dynamic temperature control performance against changes in fluidized bed temperature caused by fluctuations in combustion conditions was poor. 1. The effect on the boiler load due to fluctuations in the amount of red-hot coke processed is controlled by increasing or decreasing the amount of coke powder burned in the fluidized bed combustion furnace to prevent a drop in boiler efficiency. Therefore, when heat is removed only through the water-cooled wall, the temperature of the fluidized bed fluctuates greatly. Troubles such as tuff of this waste combustion ash and combustion extinguishing occur.

、が大部分で、残りをｃｏｔ 、 ｃｏ。For this reason, we focused on the fact that the circulating gas in coke dry fire extinguishing equipment is inert, and investigated the effectiveness of controlling the temperature of the fluidized bed by blowing part of the circulating gas into the fluidized bed. Circulating gas is N

ルすることが出来た。It is occupied by H,, H, O and other gases. Because the partial pressure is extremely low, even if it is blown into the fluidized bed, it does not contribute to the combustion of coke powder, but rather a reduction reaction of C + CO2 occurs, exhibiting an endothermic reaction, and it has been found that cooling properties are good. . In addition, the temperature of the fluidized bed could be controlled to an appropriate temperature by adjusting the amount of circulating gas blown in according to changes in the temperature of the fluidized bed.

トロールが可能となった。In this way, in addition to removing heat from the water-cooled wall, by blowing part of the circulating gas into the fluidized bed, it became possible to control the temperature of the fluidized bed with good responsiveness.

いには消火に至る。On the other hand, as mentioned above, the collected coke powder is fine and easily scattered during the fluidized bed combustion process, and the amount of the collected coke powder is determined by the superficial velocity,
In other words, it tends to increase in proportion to the amount of gas supplied, and in the region where the superficial velocity is high, that is, the blast hearth load, a large amount of coke powder in the fluidized bed is scattered, which of course reduces the combustion efficiency. If the coke powder concentration in the fluidized bed is not too low, the fire will eventually be extinguished.

飛散ダストの２段燃焼を試みた。Therefore, in order to stably sustain fluidized bed combustion when the blast hearth is loaded, it is necessary to limit the amount of air supplied to the fluidized bed.
As a result, the blast hearth load could not be secured. Blast hearth load combustion is required to compensate for the reduction in gay 2 load due to downsizing of the fluidized bed combustion furnace and reduction in the amount of red hot coke throughput. Therefore, in order to obtain high blast hearth load and high combustion efficiency, secondary air was blown into the freeboard above the fluidized bed to attempt two-stage combustion of the dust scattered from the fluidized bed.

The combustion load on the next combustion zone became extremely large, making it difficult to ensure combustion efficiency.

以下、第１図、第２図、第３図に示す実施態様例に基い
て、本発明の詳細な説明する。Therefore, as a means to improve combustibility in the secondary combustion zone, the secondary air blowing nozzle is set offset from the fluidized bed furnace core, and a large amount of coke powder scattered along with the hot gas from the fluidized bed is In the secondary combustion zone, the secondary air is swirled and mixed with air due to its swirling force. As a result, the coke powder and air have good mixing and diffusivity and are rapidly combusted, resulting in a dramatic improvement in secondary combustibility. Since this secondary combustion zone reaches a high temperature, a water-cooled pipe is disposed on the side wall to remove heat and reduce the hot gas outlet temperature. However, when the blast hearth is loaded, the heat extraction cooling of the water-cooled pipes is insufficient and the hot gas outlet temperature rises, causing safety problems for the flue refractories. (Example) Hereinafter, the present invention will be described in detail based on embodiments shown in FIGS. 1, 2, and 3.

Air is blown at 8. Since the amount of this circulating gas increases due to the combustion of coke powder, the pressure of the circulating gas main pipe 19 is measured and the gas is controlled to be released into the atmosphere by applying a pressure regulating valve so that the pressure remains constant. In order to control the secondary combustion temperature, circulating gas may be blown into the freeboard 15. In addition, since the hot gas after secondary combustion contains a lot of dust, a dust collector may be installed in the middle of the connecting pipe to remove dust.
