أنواع الفحم الحجري (Info)


يقسم الفحم الحجري إلى أربعة أنواعٍ رئيسة صُنّفت حسب كفاءتها وتركيز الكربون فيها وهي:-

  • أنثراسايت (Anthracite): وهو أفضل أنواع الفحم الحجري بحيث يحتوي على الكثير من الكربون والقليل من المواد المتطايرة، كما يسمى أيضاً بالفحم الصلب.
  • البتيومينيوم (Bituminous): هو أكثر انواع الفحم الحجري استعمالاً بحيث يمتلك الكثير من الطاقة الحراريّة عند حرقه، ويُعتبر من الفحم متوسط الجودة.
  • السبتيوميني (Soptituminous): يمتلك اللون الأسود الباهت ويُعدُّ بالرتبة الثالثة من حيث الطاقة الحراريّة والكفاءة من بين أنواع الفحم الحجري.
  • الليجنيت (Lignite): ويحتوي على أقل كميات الكربون بين انواع الفحم جميعها لدرجة أنّه يحظى باللون البني؛ لذا يُعدُّ من أردأ أنواع الفحم الحجري.
