Combustion behaviour of coal and biomass are different due to difference in their physical and chemical properties. Thermogravimetric analysis is a useful technique to determine combustion characteristics of coal/biomass blends. This study elaborates the lab scale findings of co-combustion experiments in Thermogravimetric analyzer (TGA) [in which Differential Scanning Calorimetric (DSC) and The...

(Received: January 8, 2012; Accepted: Februray 8, 2012) Abstract: The power industry is confronting challenges with seemingly conflicting goals. They provide the economy of scale needed to minimize the cost of production. Consumers, including industry, rely on affordable, dependable electrical energy. It’s an important part of our economy and our daily lifestyle. However, reducing emission leve...

Executive Summary This report examines three different methods of carbon dioxide (CO 2) capture for carbon capture and sequestration (CCS) systems for coal fired power plants. The purpose of this report is to compare the three distinct technologies for overall feasibility of large scale implementation on standard coal power plants. Many political and economic reasons have forced industries, inc...

In the past, acid mine drainage (AMD) associated with coal mining operations and the disposal of coal refuse have been a driving force behind research efforts on the properties of coal combustion products (CCPs) [1]. The results from research over the last 15 years clearly indicate that bulk-blended CCP has the potential to ameliorate AMD production in coal refuse as long as acid-base balance c...

By introducing the theory of system safety science, and applying the gray theory prediction method, this paper aims at analysing the major hazards of spontaneous combustion of coal, and divided the impact indicators system into three categories, namely; static indicator, dynamic indicator, and intensive monitoring indicator. The static class indicator determined the hazard class by using risk e...

The ENCOAL Corporation has shipped, to two utility customers, over, 500 rail cars (six partial trains and two full trains) of solid product’(PDF) from its plant located at Triton Coal Company’s Buckskin Mine near Gillette Wyoming. Shipments span a range of blends from 15% to essentially unblended PDF. Utility handling of these shipments is comparable to that of run-of-mine Buckskin coal. Result...

Comment 1: “This article presents some interesting conclusions regarding the chemical mixing state of particles produced from the combustion of pulverised coal. It would be useful, however, to expand the discussion to cover differences between the single particle mass spectra reported here and those obtained for power generation-related coal combustion and domestic coal combustion in other prev...

Laden et al. (2000) recently reported results of applying factor analysis to data taken in six cities from 1979 to 1988, identifying airborne particle sources potentially affecting daily mortality. These authors sought relationships between source groups and risk measures using source tracer elements, Se (coal combustion), Pb (light-duty motor vehicle sources), and Si (crustal--soil dispersion)...

China is the biggest coal product and consumption country around the world. Lots of coal consumption resulted huge carbon dioxide (CO2) emission, especially for coal-fired power plant in China. Oxy-fuel combustion is currently considered to be one of the major technologies for CO2 capture in power plants. The ash formation mechanism and mineral transformation in high CO2 atmosphere is different...
