Low-volatile coal

The low-volatile coal of grade T (Lean) is mainly used at electric power stations and cement factories. T-grade coal is also exported as PCI for iron and steel plants. The sorted form of T-grade coal of 13—50mm or 50—300mm fraction (smokeless fuel) is used for municipal and domestic purposes in small boiler houses equipped with furnaces having fixed railings and fuel hand-feed.

Distinguishing characteristics of T-grade coal are as follows: low volatile matter content within 8-14%, high calorific value in the range from 6000 to 6800 kkal/kg and low sulfur content — as little as 0.5% (for the Kuzbass coals).

Main users of T-grade coal in the Russian Federation:

  • ОАО Mosenergo (Moscow Region Generating Company)
  • ОАО OGK-1 (First Generating Company of Wholesale Electricity Market)
  • ОАО OGK-3 (Third Generating Company of Wholesale Electricity Market)
  • KES Holding (Integrated Power Generation Systems)
  • ОАО RUSAL Achinsk Alumina Refinery
  • Cement factories of ОАО “Sibtsement”
