Sentences with phrase «making coal combustion»

This is happening to thousands of Americans right now — and the toxic waste is coal ash, the by - product of burning coal for energy.Coal - fired power plants produce approximately 131 million tons of waste per year, making coal combustion waste the second largest industrial waste stream in the U.S. Coal ash contains numerous hazardous chemicals, including arsenic, selenium, lead, mercury, cadmium, chromium, boron, thallium, and aluminum.

The comment, made during a Jan. 17 interview with the editorial board of The San Francisco Chronicle, essentially explains how the kind of cap and trade mechanism sought by both Mr. Obama and Senator John McCain (the latter at least in his platform, if not on the stump) would make coal combustion ever more costly (unless the world finally gets serious about investing in large - scale testing and deployment of systems for capturing and burying carbon dioxide).

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.

Raypierre makes the case very clear in the current Chicago Int» l Law J. that closed system combustion with oxygen can avoid much of the externalization of costs built into current plants; I imagine it can even contain the uranium and thorium fallout from coal (which is worse than that from a properly operated fission plant).

You can get about 50 times the energy out of solar cells covering the same area as a bio-reactor tank that depends on photosynthesis, so I don't think the idea that fertilizing bio-fuels with the CO2 from coal combustion makes sense.

And for those of you who want to insist that aerosols produced by the uncontrolled burning of coal neutralized the effects of AGW from 1940 to 1979, please explain how the same argument could not be made for the effects of coal - induced aerosols during this earlier period, when no constraints on the polluting effects of coal combustion were present at all.

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...?

What this means in plain English is, for example, that making coal or crude oil combustion more efficient could count as climate finance.

I am all for making fossil fuels cleaner, and much work has already been done to make various fossil fuel devices (coal - fired power stations, internal combustion engines, etc) emit less pollution like NOx, SOx, Hg, Pb, and particulates.

Fossil Fuel is a generic term that isn't quite correct Natural Gasoline is a distilled derivative of oil but almost all ofit is manufactured from cracked and recombined oil derivativeswhile natural gasoline is further refined intoPropane, butane, Proproline (a plastics feed stock), and Natural gasand also separates out sulfur (for fertilizer and explosives) Gasoline can be made from coal («Coaline») or from organic matter («Bio-fuel») but uses a few of oil based feed stocks instead tomake «Sythiline» (artificial gasoline) This gasoline is actually cleaner burning then natural gas with allit's «flare offs» (butane, propane, propoline, sulfur) used in theearly 19th century because it is manufactured only with essentialHydrocarbons Diesel fuel is also becoming more and more Manufactured instead ofdistilled as demand for it rises but improvements in Hydro cleaningis allowing for diesel with no volatile chemicals like sulfur andmercury (taken out for petro - chemical feedstock to make fertilizerand thermometers) In both cases what you have is pure hydro - carbons, a carbon atomwith hydrogen atoms attached to it In the case of gasoline there is CH1, cH7, CH11 When in a combustion engine the gasoline is sprayed into the pistonafter being mixed with air and the drive of the engine compressesthe the chamber filled with the gasoline mist until it's full downstoke then the spark plug causes the Exothermic reaction... which isthe conversion of the potential energy in the gasoline mist to heatand force, with the force side of that equation shooting the pistonupward and the top of the stroke kicking what's left of thecaramelized gasoline mist out into the Emission control box If the Emulsion control box wasn't there to filter out the burntgasoline particles, any potential additives and volatile chemicalsthen the caramelized gunk hitting air would create CARBON MONOXIDEin the cooler then the heat of the engine difference CARBON MONOXIDE can also become a problem if the Emissions controlBox filter, air filters or muffler filters is worn or damaged.

the Michigan Tech scientists focussed only on deaths from air pollution linked to coal - burning power stations: they did not make a calculation about the economic costs of chronic illness linked to polluted air, nor did they estimate the health costs that might be linked to the entire coal industry, nor include the estimates of deaths that might be attributed to climate change as a consequence of prodigal fossil fuel combustion.

Importantly, the Michigan Tech scientists focussed only on deaths from air pollution linked to coal - burning power stations: they did not make a calculation about the economic costs of chronic illness linked to polluted air, nor did they estimate the health costs that might be linked to the entire coal industry, nor include the estimates of deaths that might be attributed to climate change as a consequence of prodigal fossil fuel combustion.
