PFA-THE ENVIRONMENT AND SUSTAINABILITY

摘要

Coal fired power stations supply around 37 percent of the UK's electricity. With the well-publicised issues of security of electricity supply relating to natural gas, timescales involved for the development of new nuclear power stations and slow development of renewable forms of electricity generation, it appears pulverised coal fired power generation will be here for some time to come. Even in future years, the development of clean coal power stations with carbon capture will still lead to the production of ash. It is said that coal reserves around the world will last some 200 years -such a resource cannot simply be ignored. The UK Quality Ash Association (UKQAA) is a trade association representing the producers and users of coal fired power station ash products. Ash is an inevitable consequence of burning coal as it results from soil and minerals laid down with the coal many thousands of years ago. In UK coal fired power stations there are two main types of ash produced - furnace bottom ash (FBA) and pulverised fuel ash (PFA) - also known as fly ash in some applications and many countries. The association promotes its members' interests of an environmental, scientific, technical and educational nature associated with all applications of coal ash products. This is achieved by sponsoring research, promoting the range of applications for ash products, representation on standardization committees, exhibitions, lunchtime presentations, etc.
