FUNDAMENTAL STUDY ON CONCRETE WITH COAL GASIFICATION SLAG
Cement Science and Concrete Technology, 2012 The thermal power generation is one of main generation of electricity in Japan. The fuels of thermal power generation are coal, oil and liquefied natural gas. While the price of coal is stabilized, the emission rates of CO₂ , SOx, NOx, dust and soot from coal fired power station are very large compared with other fossil fuels.

A Brief Review of Viscosity Models for Slag in Coal Gasification [PDF]
, 2011 Many researchers have defined the phenomenon of 'slagging' as the deposition of ash in the radiative section of a boiler, while 'fouling' refers to the deposition of ash in the convective-pass region. Among the important parameters affecting ash deposition that need to be studied are ash chemistry, its transport, deposit growth, and strength ...
