Abstract
Pulverised coal combustion (PCC) power plant with supercritical (SC) steam parameters have
been operational for over forty years and ultra-supercritical (USC) PCC plant have been
operational for just over twenty years. This significant amount of operating experience is
valuable regarding the performance of high temperatures steels. For example 9–12% chromium
martensitic steels have had problems with cracking and some have not been as strong as they
were projected to be. Additionally, PCC power plant have been operated outside of design

Abstract
In recent years, the considerable increase in the price of crude oil and natural gas and concerns about
their security of supply focused attention on whether fuel for power production and feedstocks for the
chemical industry could be obtained from the gasification of coal. The need to reduce greenhouse gas
emissions has enhanced the prospects of power generation from Integrated Gasification Combined

Abstract
It has been estimated that 780 Mt of coal combustion products (CCPs) were produced worldwide in
2010. Only about 53.5% were utilised, the rest went to storage or disposal sites. Disposal of coal
combustion waste (CCW) on-site at a power plant may involve decades-long accumulation of waste,
with hundreds of thousands, if not millions, of tonnes of dry ash or wet ash slurry being stored. In

Abstract
There are many items to include when considering the sustainability of biomass for cofiring, and some
of them are hard to quantify. The focus of this report is on the greenhouse gas emission aspects of
sustainability. The reduction of greenhouse gas emissions achieved by substituting biomass for coal
depends on a number of factors such as the nature of the fossil fuel reference system, the source of the

Abstract
In pulverised coal combustion (PCC) power plant, increasing the maximum temperature of the steam
cycle increases the electrical efficiency, which in turn lowers both coal consumption and flue gas
emissions. However, the maximum steam temperature is limited by materials that can operate at these
conditions for practical service lifetimes without failure. The EU, USA, Japan, India and China all have
