摘要： PURPOSE:To utilize the sensible heat of a hot coil effectively by a method wherein a hot coil wound in a hot rolling operation is put into water in a water tank to produce hot water, then the hot water is passed through a heat exchanger to produce clean hot water, which is supplied to a line where it is required. CONSTITUTION:A plurality of hot coils 2 wound at a temperature of about 450- 700 deg.C are immersed in water in the water tank 1 to convert the water into hot water of about 90-98 deg.C. In this case, the tank 1 is closed by a cover 3. The hot water obtained in the tank 1 is fed to the heat exchanger 6 by a pump 5, and it is brought into heat exchange with fresh water to produce clean hot water. The clean hot water of about 50-100 deg.C is fed through a branch pipt 23 to process lines 24, 25, 26 where it is required, while the hot water cooled to about 30 deg.C through the heat exchange is returned to the tank 1 via a circulating pipe 7. In addition, the clean hot water is fed to the secondary heat exchanger 11, where it is heated to a temperature of about 130-300 deg.C by exhaust gases, and the thus obtained hot water is used for driving a turbine 16 to generate electric power through a generator 17.
摘要翻译：目的：通过一种将热轧操作中缠绕的热线圈放入水箱中的水中产生热水的方法，有效地利用热线圈的显热，然后将热水通过热交换器产生清洁热水，供应到需要的线路。构成：将在大约450-700℃的温度下缠绕的多个热线圈2浸入水箱1中的水中，以将水转化成约90-98℃的热水。在这种情况下，罐1由盖3封闭。在罐1中获得的热水通过泵5供给到热交换器6，并与淡水进行热交换以产生干净的热水。将大约50-100℃的干净的热水通过分支管嘴23供给到需要的处理管线24,25,26，而通过热交换冷却至约30℃的热水返回到水箱1通过循环管道7.此外，清洁的热水被供给到二次热交换器11，在其中通过废气将其加热到约130-300℃的温度，并将得到的热水用于驱动涡轮机16以通过发电机17产生电力。

摘要： PURPOSE:To make it possible the management of amount of air blown to blast furnaces by eliminating changes in the air with a part of cool air to be blown to the blast furnace used for the cooling medium of the heavy oil burner for the blast furnaces. CONSTITUTION:Air from a blower 1 is controlled with an orifice 0 and fed to a cool air main pipe 2. Most part of air blown is sent to a regenerator 12 of the hot stove from a branch pipe 3 and heated up to a high temperature. Then, it is fed to a tuyere of the blast furnace from a blowing piping 10 through a combustion chamber 13 and a mixing chamber. On the other hand, cool air required for cooling a heavy oil burner 7 is inducted from the cool air main pipe to a cooling device 4 through a cooling air pipe 2' where the temperature of the air is lowered down to 80 to 100 deg.C to make up for pressure loss due to cooling by a booster 5 and then, sent to the heavy oil burner 7 to cool thereof. With such an arrangement, the heavy oil burner 7 of the blast furnace avoids damage due to high temperature, while there is no change in the amount of air blown to the blast furnace, thereby ensuring smooth operation.

摘要： PURPOSE:To save drying heat sources and to perform stable pneumatic feeding safely at a low cost by performing drying of pulverized coal and blowing into a blast furnace by the use of the waste gas of a hot stove. CONSTITUTION:Coal is fed with a belt conveyor 2 from a hopper 1 into a ball mill 3, where it is pulverized. On the other hand, a fuel gas A and air B are fed by blowers 5, 5 into a heating furnace 4 where they are mixed and burned and the waste combustion gas at high temp. (about 1,300-1,500 deg.C) is produced. The hot stove waste gas C (about 100-250 deg.C) conducted through the combustion waste gas duct (not shown) of a hot stove is fed by a blower 6 into said heating furnace 4, where it is mixed with the above-mentioned waste combustion gas, and the mixed gases are fed to the mill 3. While drying the pulverized coal, these gases are fed to a cyclone 7. The gases are further discharged through a bag filter 9. The separated pulverized coal is flowed through a blower 13 from a coal bin 11 and is mixed with the carrier gas D consisting of the waste gas of the hot stove. This mixture is blown into a blast furnace 14 through a tuyere 15.
