Coal is a major source of energy. The available Indian coal quality is very poor having very high ash content and low calorific value. Indian coal generates a large quantity of ash as a by-product of combustion. The objectives of the present study were to reduce the ash content of coal to produce ultra-clean coal. The coal was treated wi...

the present paper deals with the results of the foresight analysis concerning the development of energy technologies in upper silesia. twelve experts representing science, industry and independent authoritieswere involved in these investigations. upper silesia is a specific region in poland, characterized by coal energy technologies. as 9 result of steep and swot analyses several scenarios of e...

The increasing environmental concern caused by the use of fossil fuels and the concomitant need for improved combustion efficiency is leading to the development of new coal cleaning and utilisation processes. However, the benefits achieved by the removal of most mineral matter from coal either by physical or chemical methods can be annulled if poor coal combustibility characteristics are attain...

clean hydrogen is the major energy carrier for power production. the conversion of co to co2 and zero emission during hydrogen energy production causes high capital cost. it is a matter of prestige to optimize the process in order to make zero emission and cost effective production of clean hydrogen energy and electric power. in this era, coal gasification is the most promising technology for t...

Implementation of clean mining technology at coal mines is crucial to protect the environment and maintain balance among energy resources, consumption, and ecology. After reviewing present coal clean mining technology, we introduce the technology principles and technological process of paste backfill mining in coal mines and discuss the components and features of backfill materials, the constit...

Abstract This paper analyzed the current situation and development trends of energy consumption carbon emissions, trend coal in China. In context recently established peak neutralization targets, this put forward main problems associated with green low-carbon utilization coal. Five key technological innovation directions mining were proposed, including development, intelligent efficient mining,...
