ものである。Detailed Description of the Invention This invention is a sintering exhaust heat recovery system that recovers exhaust heat from sintering machine exhaust gas in a sintering factory and sintered ore cooler exhaust gas, generates superheated steam, and drives a turbine generator. This relates to improvements in equipment.

れる。Conventionally, the steam generated by heat exchange between the exhaust gas and water in the ore discharge side of the sintering machine and the steam generated by heat exchange between the exhaust gas and water in the ore feed side of the sinter cooler are combined into a single system. A sintering heat exhaust device is known that mixes and holds steam in a steam drum and drives a steam turbine using the mixed steam. A conventional example will be explained with reference to FIG. 1 is a sintering machine;
The charged raw materials are ignited by the ignition furnace 2 and moved toward the ore discharge section 3. During the transfer, air is taken in from the lower wind box 4, and the taken-in exhaust gas passes through the intake main pipe 5 to the main exhaust fan. It gets sucked in. The exhaust gas in the wind box 6.7.8 near the end of the wind box group in the exhaust gas is led to the heat exchanger 9 and exchanged heat, then enters the intake main pipe 5 and joins other exhaust gases to the main exhaust gas. It is sucked in by the wind machine. Steam generated by this heat exchanger 9 is guided to a steam drum 10.

る。On the other hand, the high temperature sintered ore discharged from the sintering machine is sent to the cooling machine 11.
The sintered ore is fed into the sintered ore and transferred to the ore discharge section of the cooler, but during the transfer, cooling air is blown upward from below by the wind box 12 and 13 to cool the high temperature sintered ore.
The air is superheated and enters the hood 14 and is passed by conduit 15 to the heat exchanger 16 of the cooler. The exhaust gas after heat exchange is circulated and used as cooling air. Steam generated from heat exchanger 16 enters steam drum 10 via conduit 17. Steam drum 10 receives steam from heat exchangers 9 and 16, which are mixed and averaged. This averaged steam is supplied to turbine power generators, and stable electric power can be obtained.
しかしながら、第１図に示す例では次の欠点を免かれる

乃至２８０℃の過熱蒸気しか得ることができない。この

量が多い。１例として、圧力１４ｋｇ／ｃＪＧ温度が２
８０°Ｃの過熱蒸気の場合、８．５ ｈｇ／ｇ’／Ｈ。However, the example shown in FIG. 1 cannot avoid the following drawbacks. Since the recovered gas temperature is 300 to 350℃, the recovered steam is 8 to 14 kg/cJG and 250℃.
Only superheated steam between 280°C and 280°C can be obtained. Because it is low-pressure steam, in order to install a high-output turbine, the governor of the turbine population must be large.
It is difficult to achieve large capacity. Furthermore, since the adiabatic length is small and the turbine output is small, the amount of steam consumed per 116'/H is large. As an example, if the pressure is 14kg/cJG and the temperature is 2
For superheated steam at 80°C, 8.5 hg/g'/H.
Ｈｔ（断熱長）＝１８５Ｋｃａｌ／ｋｇとなる。さらに

いる。いま、１４ｋｇ／ｃＪＧの圧力では、飽和蒸気温
度が約１９７℃であるため３００℃以上の過熱度が必要
なわけである。Ht (insulation length) = 185 Kcal/kg. Furthermore, the machine is slow and large, resulting in poor mechanical efficiency. Next, if we talk about the degree of superheating of steam, it is generally 10% higher than the saturated steam temperature.
It is said that a degree of superheating of 0°C or more is required. Now, at a pressure of 14 kg/cJG, the saturated steam temperature is about 197°C, so a degree of superheating of 300°C or more is required.
ところが、排ガス温度が３００乃至３５０℃であるため
ガスと蒸気の熱交換により所望の３００℃以上の過熱度
を得ることは極めて困難であると云わざるを得ない。However, since the exhaust gas temperature is 300 to 350°C, it must be said that it is extremely difficult to obtain the desired degree of superheating of 300°C or more through heat exchange between gas and steam.

It is characterized in that superheated steam of 340 to 370°C is generated at g/cJG and supplied to the turbine.
