1999-12-1 · The pulverised coal used in this study is a Victorian brown coal from the Loy Yang coal field. This is a typical high-sodium coal containing discrete mineral particles (SiO 2), particularly in sizes from about 8–80 μm. For this particular coal Na, Ca, Mg and S are bound within the coal matrix to oxygen functional groups.
2009-2-23 · The site was used as a boiler house for a paper mill beginning in 1918. The coal fired boilers were converted to fuel oil systems in the mid-1960s. The paper mill closed operations in the late 1970s. In the early 1980's the boiler house was leased to an automotive and boat repair business. The property has since been abandoned and acquired by
