low heating value

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 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。

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。
