An apparatus using fluidized partial-oxidation technique is described for distilling various bituminous coal fines, ranging from the noncaking Fushun coal up to the highly agglomerating and expanding Lou-ping coal. The operations have proved successful and satisfactory. The results have shown that in the presence of due amount of steam in the air stream and stirring device in the reactor, agglomerating coals can be handled in this apparatus and the tar yields ef bituminous coals may be as high as over 100% of...

An apparatus using fluidized partial-oxidation technique is described for distilling various bituminous coal fines, ranging from the noncaking Fushun coal up to the highly agglomerating and expanding Lou-ping coal. The operations have proved successful and satisfactory. The results have shown that in the presence of due amount of steam in the air stream and stirring device in the reactor, agglomerating coals can be handled in this apparatus and the tar yields ef bituminous coals may be as high as over 100% of that of the Fischer assay. Coke particles thereby obtained from the low-temperature carbonization are easily breakable and have higher activity than ordinary semicoke fines. This would serve as a technical basis for the complex utilization of boiler fine fuels.

低溫干餾是煤綜合利用的重要途徑之一,与火力發电相結合的粉煤低溫干餾是切待解决的問題。在实验装置上研究用飽和空气为热載体,以流化床單反应器处理粘結性粉煤,获得了一定的結果,認为装置比較簡單,操作容易,收油率与处理强度也較高。現正进行处理能力为10吨/日的半工业試驗。

The method of turbine regulation has to be considered in the design of steam boiler reheater.From the point of economy,it may not be necessory to control the reheat steam temperature,but for the sake of sabety,it has to be controlled within limits. The variation of reheat steam temperature,at different boiler load,is con- cerned with the percentage of direct radiating heat,absorbed by the reheater from the furnace. The reheat steam temperature changes sensibly by the voriation of flame position in furnce,so it is good for conditional regulation.Gas recirculation is the most popular method for reheat control,the omount of recirculing gas is concerned with the location of the reheater in the gas passages.However,the flue gas heat loss of the boiler set will be increased when the gas recirculation is opplied.For reheat control,the method of steam by-pass will not affect the high pressure steam temperature,but the omount of high alloy steel for the ma- nufacture of reheater is much more increased.When using gas damper for regu- lation,if a part of the primary superheater heating surface is placed in poralld with the reheater,the reheat control will increase the difficulty for the control of primary steam temperature. In practice,each control method requires certain feasible condition for its opplication ond also has limit of temperature controlling range.

中间过热器的设计与汽轮机的调节方法有关。从经济方面看来,对二次汽温不一定要进行调节;但从工作安全方面来看,这种调节是必要的。在不同负荷下,二次汽温的变化同中间过热吸收炉膛辐射热的百分量有关。用喷燃器倾角调节时,二次汽温的变动最灵敏,因而适于作动态调节。烟气再循环是最常用的调节方法,所需再循环烟量同中间过热器所处的烟温地带有关。烟气再循环会增大锅炉机组的排烟热损失。蒸汽旁路的调节方法不影响一次汽温,但中间过热器所需金属用量增多。当用烟气挡板调节时,如一次和二次过热器并例工作,则二次汽温的调节将增大一次汽温调节的困难。实际上每种调节方法均有一定的适用条件和调节幅度的限制。
