A new and prospective process for coal carbonization has been described. Radiant heat is used as the heating source to achieve high speed thermal decomposition of coal at high temperature.Products obtained by this process are more valuable than that of the ordinary carbonization. As for example, when brown coals from Shulan are thermally decomposed in this radiant-type oven at 850℃, the following products are obtained, viz. coal gas (heating value 4000 kcal/M~3), 570 M~3/t. coal (d.a.f.); unsaturated hydrocarbons...

A new and prospective process for coal carbonization has been described. Radiant heat is used as the heating source to achieve high speed thermal decomposition of coal at high temperature.Products obtained by this process are more valuable than that of the ordinary carbonization. As for example, when brown coals from Shulan are thermally decomposed in this radiant-type oven at 850℃, the following products are obtained, viz. coal gas (heating value 4000 kcal/M~3), 570 M~3/t. coal (d.a.f.); unsaturated hydrocarbons in gas, 30 M~3/t. coal (d.a.f.); crude benzol 2.7%, and coal tar 8% of coal (d.a.f.). In the crude benzol there are more than 90% aromatics, in which the ratio of benzene and toluene is 3:1. The conversion of coal into volatile matter is 8% more than the volatile matter in the coal used, and in the coke breeze the volatile matter remained is still 10% or more. The reactivity of the coke breeze is very high and may be used for gasification or as fuel.When the stream of coal particles passes through the radiant-type oven, its temperature can be raised promptly to about 900℃ in a time within two seconds. For every M~2 of heating surface, 100 kg of coal particles may be treated per one hour in this type of oven.

本文实验结果证明,利用辐射加热进行煤的高温高速热分解,是一项有发展前途的新工艺。它能显著地提高煤热分解化学产品的质量与收率.例如舒兰褐煤在辐射炉中850℃下热分解,产品煤气(4000大卡/米~3)为570米~3/吨煤(可燃基)、烯烃为30米~3/吨煤、粗苯为煤的2.7%、焦油为煤的8%.粗苯中含芳烃90%以上,其中苯与甲苯比为3∶1.这些产品比高温炼焦的化学产品都有成倍的增长.煤的热分解转化率较原煤的V~Γ尚高出8%,焦渣的V~Γ仍有10%,故热分解的挥发产物多、焦渣少.焦渣的活性很强,可作气化原料或燃料.煤料在辐射炉中的升温速度最高可达到500℃/秒.辐射炉生产能力高,每平方米的加热面积约可处理煤料100公斤/时。

The effect of local hyperthermia induced by ultrasound on animal's tumors was studied and served as the basis for trial treatment of human superficial malignant turmors. The results were satisfactory. Experiments on animals showed that heating of the tumor with ultrasonic apparatus combined with suitable doses of radiotherapy obtained better clinical therapeutical effects. With this combination the radiation dosage therapeutical could be reduced to one fifth of the dosage required for radiation alone. The ratio of successful tumor inhibition was 99.7%, 31.3% higher than that of mere radiotherapy.Using ultrasound to induce local hyperthermia has many advantages. For example, a new focused ultrasonic heating system can be set up for the deep local hyperthermia in the cancer therapy to obtain better resuits, while the radiotherapist will be less exposed to radiation. The system consists of an ultrasonic transducer system and an electronic power transmitter of 1MHz operating frequency. The temperature within the tumors can be controlled automatically. A schematic block diagram of the instrument together with the electronic circuits used in the apparatus is also presented.

加热能增强对恶性肿瘤的杀灭,将肿瘤区加热到43℃并维持不变,那么治疗的效果将明显增加。超声加热较其他方法具有显著的优点:利用聚焦换能器可以加热人体深部肿瘤;加热面积较大;对正常细胞和医务人员无损伤;超声对肿瘤的非热效应等。 从1981年开始我们试制了一台性能较为完善,温度能自动测量和控制的超声治疗机,至今已安全可靠地工作了三年。经与上海肿瘤医院合作,进行了大量的动物试验和临床应用,取得了较显著的疗效,肯定了超声加热对治疗恶性肿瘤的重要作用。 本文例举了动物的试验结果。表明用加热结合放疗的方法,对小鼠S_(180)肉瘤的抑制作用尤其明显。其瘤重抑制率为99.7%,单纯放疗仅为68.4%,而且放射剂量较两者结合要大五倍。通过1984年的临床应用,对人体表浅肿瘤同样有显著的疗效,取到较满意的效果。本文同时介绍了为实现上述目的所设计的治疗机的总体方案,原理框图。并对其中的电子线路作了综述。

A Top-Combustion stove of ACL type, developed through laboratory and pilot test, was carried out the industrial experiment at Lengshuijiang Iron and Coke Works in March 1987, and important data of operation had been obtained.

A Top-Combustion stove of ACL type, developed through laboratory and pilot test, was carried out the industrial experiment at Lengshuijiang Iron and Coke Works in March 1987, and important data of operation had been obtained. Through more than 4 months operation it showed that if only blast furnace gas being used the highest dome temperature reached 1375℃ the average 1267℃ and the maximum blast temperature at stove exit was 1320℃ the average 1267℃ short-flame burner has been operated with high stability and at a smaller excess air ratio of 1.02-1.05. Designed construction of ACL type stove is logical and the radial-temperature distribution is more uniform, so, construction deficiencies of conventional type have been avoided. The operation of top-combustion stove is the same as the traditional one and much safer. Investment per 1 m~2 heating surface in top-combustion stove is 4% higher than that for the reconstruction of internal combustion type, but the heat efficiency and blast temperature obtained are much higher. These would result in obvious benefits. It is suitable and applicable to either the reconstruction of old blast furnaces or building new ones.
