空气

These two elaborate laboratories, ventilation/fire protection laboratory and exposure chamber, can be simulated as the occupational workplace. Students will have opportunities to gain the practical discipline within campus, such as fire scene examination, fire fighting tool use, fire protection system establishment, and exposure assessment etc. Three curricula have been compiled as a guide to assist students to get more understanding on the hazard identification within campus.

本校是全国唯一同时设有消防实习教室及暴露舱实习教室的学校，可模拟火灾发生时之情景，进行水雾系统操作、各种灭火工具使用、防火系统设置等实习教学活动，学生并可利用暴露舱室进行暴露空气中危害物质之体验教学，更能加深学生了解空气品质对健康危害之认知，同时在使用个人防护具的教学中，学生能有实作的机会，这是本教学方案最大的特色。

To avoid loss of drilling tools and even well abandonment due to downhole fire or explosion during air drilling in pay zones, we developed a novel downhole fire or explosion prevention sub, a kind of downhole tool made of low melting-point alloy, designed to shield off oxygen so as to put out fires. This sub is connected to the upper part of dill bit.

为了解决空气钻井在钻遇油气层时，发生井下燃爆，造成埋钻具、井眼报废等复杂情况，基于阻断氧气使火熄灭的思路研制出了一种低熔点合金制造的井下工具－空气钻井燃爆灭火阀。

Through the flue gas and air characteristic analysis in supercharged boiler,the results showed that the value of parameters would increase with the increase of fuel consumption.And volume heat load of the furnace, fuel consumption, heat change between flue gas and convective heating surface and evaporation value would increase with the increase of compression ratio.The heat calculation would be different because of dissimilar thermal calculation in the turbo-compressor when the boiler load was changed.As the boiler load increased,heat loss in the turbo-compressor would increase and the efficiency of the boiler would decrease.The results of the boiler start-up simulation showed that the time of start-up would decrease with the increase of flue consumption ,but instantaneous pressure amplitude would increase.Steam water"s dymamic diversification would be more complex than flue gas"s,and dynamic characters of their parameters would be changed due to different boiler load and disturbance variable,which was shown by results of the simulation when boiler load was changed.

通过分析增压锅炉内的空气、烟气参数特性，发现随着锅炉负荷的增加，空气和烟气的各项参数值都相应的增加；炉膛容积热负荷、锅炉的燃料负荷随着增压比的提高成比例增加；随着增压比的增大，烟气与对流受热面的换热增加，蒸发量随之增加；由于涡轮增压机组在不同负荷下的热力计算不同而造成增压锅炉在不同负荷下的热平衡计算的不同；锅炉增压机组的总的热损失随着锅炉负荷的增加而增加，而增压锅炉的热效率随着锅炉负荷的增加而减少；锅炉启动模拟仿真结果中发现，锅炉启动时燃料量增加，锅炉的启动时间就会减少，但是瞬时升压速度会增加；而动态负荷变化模拟仿真结果中发现，锅炉汽水侧的变化相比烟气侧更为复杂，且在不同负荷和不同扰动量下，烟气侧和汽水侧的重要参数动态特性是不同的。

The gas burning and air preheating procedure in flues operates on a cyclic basis in which some flues are burning gas and others are giving up their heat to incoming combustion air.

烟道中煤气的燃烧和空气的预热是循环进行的，当某些烟道正燃烧煤气时，另一些烟道则在加热导入的供燃烧用的空气。

Air for combustion is drawn into the battery heating system,where it is heated by passing through flues in which gas was earlier burnt, then the preheated air is introduced into individual heating flues to support combustion of gas provided through jets.

燃烧所需的空气被引入焦化设备的加热系统，并使其通过其中已有燃烧着的煤气的烟道而被加热。然后，预热过的空气被导入各个加热烟道以维持由入口喷出的煤气的燃烧。
