This presentation is a pure steam-plasma torch generated by microwave energy and uses it for coal gasification in a lightweight operating system. The high temperature of the steam torch when used for fast gasification reactions of low-grade coal ensures a compact reaction system for an electrical power plant.

Coal-fired power plants account for nearly 50% of U.S. electricity supply and about a third of U.S. emissions of CO(2), the major greenhouse gas (GHG) associated with global climate change. Thermal power plants also account for 39% of all freshwater withdrawals in the U.S. To reduce GHG emissions from coal-fired plants, postcombustion carbon capture and storage (CCS) systems are receiving consi...

A thermal power station is a power plant in which the prime mover is steam driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine, the steam is condensed in a condenser and recycled to where it was heated; this is known as a Rankine cycle. The greatest variation in the design of thermal power stations is due ...

Visceral leishmaniasis (VL) or kala-azar mainly affects children in endemic areas. This study was conducted to determine the seroprevalence of VL using direct agglutination test (DAT) in children living in rural districts of Alborz Province located 30 km from Tehran capital city of Iran. Multi-stage cluster random sampling was applied. Blood samples were randomly collected from 1,007 children u...

Substitution of coal in coking blend with bio-coal is a potential way to reduce fossil CO2 emissions from iron and steelmaking. The current study aims explore possible means counteract negative influence cokemaking. Washing kaolin coating bio-coals were conducted remove or bind part the compounds ash that catalyzes gasification coke CO2. To further how increase reactivity related more reactive ...

The calorific value of coal is an important factor for the economic operation of coal-fired power plant. However, calorific value is tremendous difference between the different coal, and even if coal is from the same mine. Restricted by the coal market, most of coal fired power plants can not burn the designedcoal by now in China. The properties of coal as received are changing so frequently th...

In China, coal combustion to generate electric power is the primary method, the energy-saving and emission reduction is the urgent task. At present, the energy-saving dispatching trial method in some area evaluates energy-saving and emission reduction of coal combustion power generation according to power supply coal consumption rate only. But the power supply coal consumption rate can’t reflec...

a notable amount of medicinal plants grow in iran and local communities in different parts of the country have developed a deep knowledge of various uses of plants during their old history. several ethnobotanical studies have been conducted by the traditional medicine and material medica research center (tmrc) to investigate the use of medicinal plants by local people. some of these studies hav...

The accumulation of heavy metals in naturally occurring plants of herbs, shrubs and trees grown on South Bolanda coal mine overburdens in subtropical region of India were illustrated.. The inter-elemental relationships of different parts of five plant species including herbs, shrubs and trees with the coal mine wastes were studied. From the tree species maximum positive correlation was observed...
