 * Liza Elliott
 * Chris Spero
 * T. F. Wall

After the close of the Callide Oxyfuel Project, mature deposit samples were
collected from the primary and secondary superheater tubes. These samples were
studied with the aim of providing a description of deposits from an industry
scale oxyfuel plant and to gain some understanding of the deposition mechanism
involved in their formation. The deposi...

In 2013, CO2 levels surpassed 400 ppm for the first time in recorded history.
So, we are facing global warming due to the increase levels of atmospheric
carbon dioxide (CO2). As a method of reducing CO2 emissions from coal fired
power plants, there are carbon dioxide capture and storage (CCS) technologies.
Oxyfuel combustion is one of the CO2 Captu...

Oxyfuel combustion is a CO2 capture technology which is approaching commercial
demonstration. Of practical interest is the use of the compression circuit to
allow low-cost cleaning options for various flue gas impurities. This work has
focussed on three species - NOx SOx and Hg - and their removal during
compression of "real" oxyfuel flue gas sampl...

The CPU (Compression and Purification Unit) is used to capture, purify and
compress the CO2 contained in oxy-combustion boiler flue gas. Therefore, it
plays a key role in the oxy-combustion route for carbon capture and storage
(CCS). Over the last ten years Air Liquide has been developing this technology
from a conceptual stage towards industrial m...

CCS, CO2 capture and storage, is one of the ways to keep CO2 concentration in
atmosphere to be under certain value in order to mitigate the global warming and
expectation for its practical use soars all over the world. IHI have developed

Co-firing of coal and biomass has been adopted by many power generators around
the world as an option for reduction of CO 2 emission. This study is part of a

Survey on wear in coal pulverizing mills part 2 - effect of grinding element
material properties
Article
 * Dec 1992

 * Chris Spero

Part 2 of this survey examines firstly, the metallurgical properties of the main
types and classes and wear-resistant ferrous alloys used for grinding elements
in coal (ore) pulverizing mills, and secondly, field data relating wear life of
these elements to alloy properties. Survey data were taken from the published
literature, material suppliers,...

Survey on wear in coal pulverizing mills: Part 1 - effect of coal material
properties
Article
 * Jan 1992

 * Chris Spero
 * R.K. Kirkcaldie

The replacement of grinding components in coat pulverizing mills represents a
significant portion of maintenance cost associated with the operation of
coal-fired power plants. This paper (Part 1) examines the nature of the wear
processes occurring in different mill types, and evaluates the impact of certain
coal properties on the wear characteristi...

 * Harvey James Flitt

Maintenance costs associated with wear in coal grinding mills operating in
Queensland pulverised coal-fired power stations are in excess of $10m per year.
In other fuel-ore and mineral-ore processing industries metal wastage through
wear and corrosion is also a major component of maintenance cost. The aim of
this paper is (1) to define the relevant...

Assessment and prediction of coal abrasiveness
Article
 * Sep 1990

 * Chris Spero

The abrasive properties of coal were measured in terms of the content,
composition and physical properties of the coal mineral matter, and the
grindability and bulk density of the coal. For a limited range of coals and
their associated relative density fractions, these properties were related to
abrasion index (AI) by an empirical equation. The res...

Corrosion performance of mild steel in coal leachate
Article
 * Jan 1988

 * Chris Spero
 * Harvey James Flitt

Producers and users of coal have for many years recognized the potential
corrosivity of coal leachate, particularly with regard to its reaction on mild
steel structures associated with coal handling plant. In this paper, the results
of a preliminary investigation of aspects of mild steel corrosion by coal
leachate prepared from four Queensland coal...
