Is “truly” clean coal attainable?
Almost everyone will agree that coal is an inherently dirty fuel. But coal is abundant, cheap and readily available for the world’s largest developing nations who’re planning to use coal to fuel their economies and provide electricity to hundreds of millions who still don’t have power in their homes. Coal is undeniable and will be around and used for the next fifty years in Asia ...

Optimal maximum continuous operating load of fuel fired steam–based generating units
This paper establishes the optimal maximum continuous operating load of fuel fired steam based thermal units without endangering the operation, asset life or carbon footprint. The interconnectivity between unit loadability and energy efficiency (represented by heat rate) enables the unit to be loaded to as high as 10% over and above the 100% maximum continuous rating (MCR) provided the energy ...

How to create qualitative fuel from water and coal: case study
What is “coal-water fuel”? Coal-water fuel (CWSF or CWS or CWF) is a fuel which consists of fine dispersed coal particles, water and plasticizing agent. This type of fuel is widely used as an alternative to gas and black oil on different heat generating facilities. The operational economy is the main of advantages of the coal-water fuel. CW fuel has almost the same heat ...

Unconventional Crude Upgrading Challenges
Crude markets are being influenced by increasing prices, stagnate discovery rates, increased world demand, and competition from alternate sources such as bio-fuels, coal and unconventional crude. Future crude supplies from conventional sources are anticipated to be, in part, incrementally replaced by production of unconventional crude from Western Canada and Venezuela, in addition to other ...

The international coal industry: comments on the paper by David Humphreys and Keith Welham
This comment discusses in more detail one of the primary messages in the paper by David Humphreys and Keith Welham, namely the fundamental shift in the steam coal industry away from security of supply concerns and national focuses towards an international and cost-driven perspective. On the supply side, this has meant an increased focus on mining productivity. By consulting recent research, this ...

EPA`s proposed underground injection control regulations
As the drivers for global climate change become better understood by scientists, politicians, industry, and the public, there is growing consensus that action should be taken to limit atmospheric emissions of carbon dioxide (CO2) and other greenhouse gases (GHGs). Even as wind, solar, nuclear, biofuels, and other alternative energy sources become increasingly important, the United States will ...

Vietnam Eco-Innovation Project
We prioritize the worldview of improving the environment and quality of life of social communities and all neighbors by reducing coal-based fuels that can prevent air environment, soil, and water pollution. We also use eco-friendly biomass fuels to reduce greenhouse gas emissions and supply natural ash. Promote the “Fuel Chain” project for continuously circulating biomass through ECO ...

Thermal behaviour study of senakin coal and Refuse Derived Fuel (RDF) blends during pyrolysis using thermogravimetric analysis
Preliminary Thermogravimetric (TG) studies of pyrolysed Refuse Derived Fuel (RDF)–coal blends (20 to 80%) at various heating rates, 20, 40, 60 °C•min–1 have been performed to develop an efficient locally sourced renewable solid fuel. The characteristics of the coal/RDF blends followed those of the parent fuels in additive manner. Among the tested blends, 50:50 blends showed the optimum blend ...

Co-firing Solid Recovered Fuels (SRFs) with brown coal in large-scale pulverised fuel power plants – a simulation approach
The results of the numerical simulations performed in a pulverised fuel boiler co-firing coal and Solid Recovered Fuels (SRFs) are presented. SRFs are initially modelled as a mixture of two different fractions (biogenic and plastic) and further simplifications are proposed to save computational expenses. The SRF submodels are validated with available data obtained from a laboratory-scale ...

Coal and fuel burning effects on the atmosphere as mediated by the atmospheric electric field and galactic cosmic rays flux
Emissions into the atmosphere of Greenhouse Gases (GHGs) and particulate matter resulting from fossil fuel burning are considered to be the main anthropogenic forcing on the global climate. We show here that the external cyclic influences of cosmic origin that modulate the earth's climate may either reinforce or mitigate the 'local' terrestrial forcings. Among the external influences is cosmic ...

Renewable energy in Armenia
Armenia does not have any fossil fuel or coal reserves; therefore, it is entirely dependent on the imported fuel for transportation, electricity generation, and heat production. Armenian Government has plans to develop renewable energy resources. Renewable energy may not be the major source of energy development in Armenia but it should be an important component of it. A renewable energy road ...

Cumulative exergy consumption (CExC) analysis of energy carriers in China
Cumulative exergy consumption (CExC), which represents the total exergy of natural resources required to provide a product, is an appropriate indicator for quantifying the depletion of natural resource. The objective of this study is to determine the CExC values of the principal energy carriers in China, which is the largest energy producer in the world, through the matrix method (balance ...

Through Briquetting Project Recycling of Biomass Waste
As we know, now a days huge amount of agro forestry waste are produced. So,it is necessary to manage the waste in the efficient manner. Jay khodiyar Machine Tools came up with the solution of this problem. We are manufacturing the biomass briquetting plant. This Briquetting Machine uses the agro forestry waste as a raw material and produces the solid biomass fuel Briquettes or White Coal. This ...

Is it possible for alternative fuels to replace traditional fossil fuels as the mainstream?
If you were a coal-burning company, would you like to choose $60 alternative fuels per ton or $180 coal fuels per ton? Of course, such a direct comparison is not reasonable because alternative fuels differ from coal in terms of calorific value of combustion and disposal costs. Let us then calculate the actual economic benefits of alternative fuels compared to fossil fuels (as represented by coal) ...

Coal is king in China
1.4 Billion Chinese consumers are each day improving their standard of living. This new Ch;ina population is certainly deserving of all Creature Comforts like air conditioning, refrigerators, PC’s – these appliances are stretching China’s energy resources. Many Environmental Experts rightfully worry that China’s energy needs will have to rely on Coal for the unforeseen ...

Effect of the radiation heat loss on propagation of the spherical flame through premixed coal dust
An analytical study has been conducted to investigate the effect of radiation heat loss on the spherical flame propagation in coal–dust clouds. This research can be valuable in the development of alternative fuels; and it can be used by the fire safety and control industry. The model includes the evaporation of the volatile matter of dust particles into a known gaseous fuel (methane) and the ...
