Initial Slagging Temperature as a Coal Slagging Index: Determination and Application*

  • THERMAL POWER PLANTS
  • Published:
Power Technology and Engineering Aims and scope

The initial slagging temperature represents a combination of various properties of fly ash, does not give a priori preference to any of them, and objectively characterizes the bonding of particles in deposits. Unlike other countries, in our country, this temperature is widely used as a main coal slagging index. This temperature measured in different experimental conditions for the same coal may differ from the temperature measured in identical conditions for different coals. The first part of this review addresses methods for determining the initial slagging temperature and the use of this index during the design and operation of coal-fired boilers.
