Why is coal consumption in coal chemical projects categorized into raw coal and fuel coal? In the feasibility studies for projects involving coal-to-oil, coal-to-natural gas, coal-to-methanol, and coal-to-ethylene glycol, there is a requirement for the use of \"fuel coal\". What is the purpose of fuel coal? Is it used for boiler cogeneration? If a cogeneration unit is planned for the utility island in an industrial park, it is necessary to calculate the coal consumption, which should be the coal consumption for raw materials in coal chemical projects plus the coal consumption for the cogeneration unit in the utility island, right?
Many chemical processing projects have specific requirements for the raw coal due to the different processes and equipment used, whereas fuel coal, which is used to generate electricity for the entire industrial park, only needs to meet the standards required for power generation
Why is coal consumption in coal chemical projects classified into raw coal and fuel coal? . . . . In coal chemical projects, the raw coal refers to the material used to produce chemical products, and generally certain requirements are placed on the quality of the coal ； Fuel coal refers to the fuel used to provide heat and electricity for chemical products, with less stringent requirements regarding its quality.
When raw coal is used as the feedstock, higher requirements are placed on its composition, while lower requirements apply to fuel coal
