1. Introduction. Xinjiang coal is a promising energy resource with a huge reserve of over 2 trillion tons, accounting for 40% of China's total coal resources [1].Among the coal resources in Xinjiang, the reserves of Shaerhu (SEH) coal are as high as 89 billion tons [2].SEH coal has good ignition [3] and combustion characteristics [4] because of its ultralow contents of sulfur (S) and ash.

When the consumed sulphur in coal is in the form of sulphur dioxide at the end of combustion, it reacts with water at high altitudes. Moreover, it goes down to the earth in the form of sulphuric acid, as well as damaging plants. The corrosive harmful impact on industrial plants is the removal of the sulphur in the coal when it is environmental.

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
