Both coal gangue and coal bed methane are lowheatingvalue fuels.
煤矸石和含甲烷量较低的煤层气均属于低热值的燃料。

Variations of the process enable production of high purity hydrogen, methanol, ammonia, methane or lowheatingvalue gas.
此过程的演变工艺可以生产高纯度氢气、甲醇、氨、甲烷或低热值气体。

As a result of lowheatingvalue and unsteady component, ignition and combustion of Municipal Solid Waste (MSW) are difficult using conventional methods.
