Sentences with phrase «coal combustion generates»

Coal combustion generates the most CO2 emissions per unit of energy.

Not exact matches

Pretreating with thermal depolymerization also makes coal more friable, so less energy is needed to crush it before combustion in electricity - generating plants.

Natural gas, which is mainly methane, may generate less carbon dioxide than oil and coal when burned, but as recent research has found, there's more to greenhouse gas emissions than just combustion.

Until recently, however, soot's role in warming has been muddied by the effects of another pollutant, sulfate particles generated by coal and petroleum combustion.

Nevertheless, Streets considered the endeavor important because China is full of the two biggest contributors to human - generated mercury, metal smelting and coal combustion.

Consider, for example, that the Tennessee Valley Authority (TVA) generates about 60 % of its energy via coal - fired power plants and combustion turbines.

The article notes that the shift to gas, so far, is restricted to the city, and some of the pollution from coal combustion will simply be generated elsewhere as plants outside the city pollute to supply electricity to the center of power.

So if the world moves toward a system for tracking emissions, who is responsible for a particular batch of carbon dioxide — the company that mined and sold the coal, the power plant that burned it, the consumer who buys the exported widget made with the electricity generated by that combustion, or...?

Coal combustion products (CCPs) are the by - products generated from burning coal in coal - fired power plaCoal combustion products (CCPs) are the by - products generated from burning coal in coal - fired power placoal in coal - fired power placoal - fired power plants.

The report found the terminal could have «significant and adverse» impact on the climate, and the combustion of coal from the terminal could generate annually as much carbon pollution as 672,000 cars.

Ultimately, coal can not be considered «clean» when you factor in the air and water pollution generated by coal mining, preparation, transport and combustion.

(5) Complete combustion of 1 short ton (2,000 pounds = 909 kg) of this coal will generate about 5,720 pounds (= 2.86 short tons = 2600 kg) of carbon dioxide» To convert CO2 mass to C mass, multiply by 0.25; 1000 kg of CO2 = 250 kg of elemental carbon.

The combustion of coal generates waste consisting primarily of non-combustible mineral matter along with a small amount of unreacted carbon.

These included replacement of high - sulfur coal with low - sulfur coal, scrubbers, electrostatic precipitators, coal cleaning techniques, and development of higher efficiency combustion techniques that allowed more electricity to be generated per ton of emissions.

But if existing combustion power plants could be adapted to use metal powder instead of coal or other fossil fuels, then much of the existing power generating infrastructure could be used, and power generation could continue to be in the same places it is now, using the same grid as is currently supplying electricity.

Depending upon the form of energy converted into electrical energy, the generating stations are classified as under: (i) Steam power stations (ii) Hydroelectric power stations (iii) Diesel power stations (iv) Nuclear power stations Steam Power Station A generating station which converts heat energy of coal combustion into electrical energy is known as a steam power station.

Thus, we neither favor nor oppose so - called «clean coal,» i.e., combustion of coal with carbon dioxide captured and sequestered from the atmosphere; though we're not bullish on Carbon Capture and Storage in light of the considerable (~ 30 - 40 %) oversizing of generating capacity and coal throughput required to process flue gas to safely remove 90 % or more of the CO2.

Those costs come from increased health care costs, deaths and injuries that result from mining and transporting coal, and the emissions generated during the coal's combustion.

«Tuning» the combustion output of the boilers causes little loss in total efficiency, implying that the biomass - to - electricity combustion efficiency is close to the 33 — 37 % range of an unmodified coal plant, an efficiency that stand - alone biomass generating capacity has yet to demonstrate.

The combustion of coal in power generating plants is used to make steam which, in turn, operates turbines and generators.

Complete combustion of 1 short ton (2,000 pounds) of this coal will generate about 5,720 pounds (2.86 short tons) of carbon dioxide.
