low heating value

The effects of equivalence ratio and volume fraction of oxygen on gas composition, carbon conversion and low heating value ( LHV) of fuel gas were investigated through a series of experiments.

实验主要考察了氧的当量比和氧体积分数对气化气组成、碳转化率和气体热值的影响。

Due to the high water content and oxygen content, its low heating value, viscosity, thermal instability and chemical instability, the bio-oil can not be directly used for the current power equipment, it needs to be catalytic hydrogenation to mention quality.

由于生物油中水含量和氧含量高，其热值低，粘度大，热不稳定和化学不稳定性，不能直接用于目前的动力设备，故需要对其进行催化加氢提质。

The gas yield increased with the increase of temperature. The low heating value ( LHV) of pyrolysis gas would decrease because of the decomposition of CH4 and C2H4 at high temperatures.

升高热解温度有利于提高热解气的产量，但是高温会使CH4和C2H4裂解，从而造成热解气热值下降。

The coal gases came from two-stage gasification process and the exhaust gases containing combustible components from chemical and metallurgical industries are all low heating value ( LHV) gas streams.

以两段法等制作的普通煤气及化工、冶金企业中含可燃组分的废气等，都是低热值燃料。
