烧石灰

Plastic is made from lime which can be obtained from the calcination of limestone widely present in nature.

塑料是由是煅烧自然界中广泛存在的石灰石得来的石灰制成的。

When refractory gold ore is roasted by addition of lime, the calcine will contain some of calcium sulfide.

难处理金矿石加石灰法焙烧时，所得焙砂含有一定量的硫化钙。

Therefore, through the thermodynamic analysis and calculation of calcining active calcareousness rotary kiln in Pan Zhihua Steel Factory, the relationships among rotary kiln efficiency, output and gas-fired quantity could be concluded.

因此，本文通过对攀钢煅烧活性石灰回转窑进行了热力分析计算，得到了回转窑效率、产量、燃气量等之间的关系，通过对各影响参数的了解，可以掌握回转窑的热工制度，同时也可以掌握熟料的煅烧状况。

My company has 10 years experience in production and processing of lime, with lime mining from the calcined to the processing of the entire production process, to ensure the provision of quality products.

我公司有10年的生产加工石灰经验，拥有从石灰开采到煅烧到加工的整个的生产流程，能保证提供优质的产品。

The moistureproof lime powder with high activity and fluidity has been made by a special calcination method,rapid grinding technique and physical passivation treatment technology.

采用特殊的石灰锻烧方法、高速粉碎技术以及特殊的物理纯化处理技术，研制出防潮性和流动性能好活性度高的新型石灰粉剂。

In this paper, the process of the cleaner roasting of shaly coal was studied.

本研究对石煤清洁焙烧工艺进行了研究，发现钙化焙烧除可完全避免钠化焙烧过程中Cl2 、HCl等有害气体的产生外，石灰在焙烧过程中有很好的固硫效果。

The invention provides a sulfur oriented adsorption control method for calcining active lime in a rotary kiln comprising the following steps: the rotary kiln calcines the massive limestone using the mixture of the coal fines and active lime fine silts as fuels, the sulfur in the flue gas is adsorbed using the sulfur adsorption and desulphurizing ability of the active lime fine silts, meanwhile the sulfur-adsorbed kiln dust is separated from the calcined active lime by means of screening to get low sulfur-content active lime.

本发明提供的回转窑煅烧活性石灰中的硫定向吸附控制方法，具体是：回转窑以煤粉与活性石灰微细粉粒的混合物为燃料，在对块状石灰石煅烧时，利用活性石灰微细颗粒所具有的硫吸附与脱硫能力对烟气中的硫进行吸附，同时通过筛分将吸附了硫的窑灰与煅烧过的活性石灰分离，而得到低硫含量的活性石灰。

Compared with coke upright stove, gas burning lime upright stove has the features of greater gas flow in stove, higher lime activity, uniform temperature, temperature control being easy, the requirement for selection on gas being low and higher consumption of heat.

与焦炭竖窑相比，气烧石灰竖窑具有窑内气流量大，石灰活性度高，室内温度均匀，温度易控制，对燃气选择要求不高，热耗高等特点。

The gas burning lime upright stove is improved at Jigang. The cylinder form was changed as rectangular plus arcuate forms, the structure of lime discharge machine was redesigned, the air and gas heat exchangers are connected in series in dedusting flue. The rate of raw and over burning of lime is less than 7%, the breakages of tooth and shafts on lime discharge machine are decreased and gas is saved.

济钢对气烧石灰窑进行改进，将圆柱型窑形改为矩形+弓形，并重新设计了出灰机结构，在除尘烟道上串联增设了空气，煤气换热器，使石灰的生，过烧率低于7%，减少了出灰机的断齿，断轴现象，而且节约了煤气。

Plastic is made,using water which is a natural resource inexhaustible and available everywhere,coal which can be mined through automatic and mechanical processed at less cost and lime which can be obtained from the calcinations of lime stone widely present in nature.

塑料是由水、煤和石灰制成的。水是取之不尽的到处可以获得的天然资源；煤是用自动化和机械化的方法开采的，成本较低；石灰是由煅烧自然界中广泛存在的石灰石得来的。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
