热值

Calorific values are used to express the energy values of fuels; usually these are expressed in megajoules per kilogram.

热值被用来表示燃料的能量值；通常以每公斤多少百万焦耳表示。

To Lieutenant Yang he said,"Monitor the engine thermals and push us past one-third power… right up to the dark-line limit."

他对杨上尉说，&监控引擎热值，让我们以三分之一全速前进···一直到明暗交界的暗边顶点。&

For installations of gas or oil-fired hot water supply boilers over 730,000 BTU/Hr.

适用于安装在燃气或燃油热水供应锅炉，输出热值超过730，000 BTU/小时的室内水和蒸汽盘管容积式热水器。

For oil-fired boilers: oil-saving rate of 8 ~ 20%; to reduce emissions and sulfur emissions, removal of the nozzle coking coke 45 ~ 95%; improve fuel calorific value 5 ~ 6%; enhance firepower 5 ~ 25%; to reduce the value of spontaneous combustion about 14% and bring the nozzle to remove coke, will notnozzle coking and improved combustion stability, also catalyzed a number of harmful ingredients, can enhance product quality and yield, extend equipment life; can improve heat transfer efficiency and reduce labor intensity work to reduce harmful gas emissions and other benefits.

对于燃油锅炉：节油率为8～20％；降低废气及硫排放、清除喷嘴积炭结焦45～95％；燃油热值提高5～6％；提高火力5～25％；降低自燃值14％左右，并带来清除喷嘴积炭，不会因喷嘴结焦而停喷，提高了燃烧的稳定性，另外还催化了一些有害成分，可提高产品质量和成品率，延长设备使用寿命；可提高传热效率，降低工作劳动强度，减少有害气体的排放等效益。

In the process of steel production, it's important to avoid serious air pollution and take full advantage of coal gas which comes from blast furnace , coke oven , or converter. Generally, we collect the gas mentioned above and store it in the storage bank or storage tower, then the gas can be transmitted to the relay pressurizing station by piping. At last, the by product can be used as fuel.

在钢铁行业生产中，为了避免严重的空气污染并充分利用高炉、焦炉和转炉产生的煤气这一高热值燃料，一般处理过程是将产生的各种煤气分别收集到贮气罐再用管道传送到中继加气站经加压后供各用户使用。

The feasibility of the relevant technical method is discussed to the problems such as lower heating value of the coal gas, the poor comprehensive use of the coal gas and so on.

针对现行低温干馏工艺存在的煤气热值低、煤气未完全回收综合利用等问题，讨论了相关技术措施的可行性。

The total content of alkanes and aromatics were up to 60.01% 57.86% for poplar leaves and birch leaves with H/C molar ratio 1.79 and 1.89, O/C molar ratio 0.035 and 0.036, and HHV 45.47 MJ·kg~（-1）and 46.03 MJ·kg~（-1）These data shows that the oil from leaves was very similar to petroleum.

树皮样品所得油中碳氢化合物成分总含量有所降低，油的热值也有所降低，大体在40MJ·kg~(-1)左右，但是在树皮所得油中出现了大量的酚类物质，百分含量在40%左右。

The experiment results indicate that the ignition method about blind hole and the linkage technology for changing blowing direction of the gasification tunnel on underground gasification without shaft style in steep coal seam are feasible.

试验结果表明，急倾斜无井式地下气化盲孔式电点火工艺，气化通道正、反向火力渗透互换贯通技术是可行的，煤气热值随煤气流量的增加而升高，并趋近于一稳定值。

Distribution of reaction zones affects the heating value of producer gas and the rate of gas generation, as well as tar content and particulates.

气化炉内之反应区分布状况不但会对产气热值与产气率产生影响，同时也会影响焦油与粒子之生成量。

The results indicate the mutual effect exists between the single coals, which could increase the maximum of thermal weight loss obviously and has a small effect on the temperature extent of the weight loss. The main pyrolysis production of coal is coke, but the main production of waste plastics is tar; the yield of water became decrease and the gas became increase by adding the waste plastics. And the CRI and CSR decreased with the ratio of waste plastics in coal. The main ingredients of tar from blend coal are aromatic hydrocarbon and alkane, while those of waste plastics are alkane and alkene. The result of co-coking with coal and waste plastics make the light tar and the aromatic hydrocarbon increase obviously. The combustible ingredient(CO、H2、CH4) of gas from co-coking with coal increase at different ratio; Co-coking with coal and waste plastics could increase the combustible ingredient and thermal value of gas.

结果表明，废塑料与煤混合物在煤的塑性温度区间内存在明显的相互作用，使最大热解失重峰迁移，热解速率变大，且随着废塑料配比的增加呈现规律性的变化；煤热解产物固体焦炭为主，而废塑料的热解产物以焦油为主，废塑料的添加使得总体焦炭和水产率下降，焦炉煤气和焦油的产率增加，即共焦化呈现出明显的&增油减水&效应；随着塑料添加量的增加，焦炭热强度呈现劣化趋势；废塑料代替瘦煤配煤炼焦可使其比例提高到3%而不影响焦炭的质量；纯煤焦化所得焦油以芳香烃类和烷烃类为主，而废塑料热解焦油以烷烃和烯烃为主；废塑料配煤炼焦，可使得的焦油呈现&环构化&和&轻质化&趋势；废塑料的添加可使煤气中的可燃组分(CO、H2、CH4)的含量均有不同程度的增加；废塑料配煤炼焦可以优化焦炉煤气的组成，增加煤气中的可燃组分，提高焦炉煤气的热值。
