An analysis was conducted on the relationship between the calorific value of different types of coal and the theoretical air requirement. It was found that the theoretical air volume required for generating the same amount of heat during combustion is the same for different types of coal. The concept of the air/coal ratio was improved by proposing the concept of the air/carbon ratio, which ...

Coal mills consume a huge amount of station service electricity power of a coalfired power plant. Meanwhile, the operation of coal mills also has a large influence on boiler combustion. Among all the operating factors, the electricity current intensity of coal mills reflects the electricity power consumption as well as operating status of coal mills. If the electricity current intensity of ...
The calorific value of coal varies considerably depending on the ash, moisture content and the type of coal while calorific value of fuel oils are much more consistent.
