摘要:
A virtual kiosk system and method are provided for stored photo-image reproduction. A photo-image discovery device, having no dedicated display, scans communication interfaces for photo-capable devices, and determines if detected photo-capable devices have stored electronically formatted photo-images. The photo-images are acquired into the photo-image discovery device, and the acquired photo-images are uploaded to a network-connected storage site. Subsequently, the photo discovery device may be interfaced to a display monitor. A menu of photo-image user prompt options is depicted on the display monitor, originating from the photo discovery device. The storage site is accessed from the photo discovery device in response to a first user prompt. In response to a second user prompt, a stored photo-image is selected. In one aspect a delivery option for the selected photo-image is selected in response to an additional user prompt.
摘要:
A method for capturing mercury in a flue gas formed by solid fuel combustion including: combusting coal, wherein mercury released during combustion is entrained in flue gas generated by the combustion; generating a thermally activated carbon-containing sorbent by partially gasifying a solid fuel in a gasifier local to the combustion of solid fuel; injecting the gasified gas products into the combustion of coal; injecting the thermally activated sorbent in the flue gas, and collecting the injected sorbent in a waste treatment system.
摘要:
A method to reduce mercury in gas emissions from the combustion of coal is disclosed. Mercury emissions can be reduced by staging combustion process and/or reducing boiler excess oxygen. Fly ash formed under combustion staging conditions is more reactive towards mercury than fly ash formed under typical combustion conditions. Reducing boiler excess oxygen can also improve ability of fly ash to adsorb mercury.
摘要:
A method is provided for preventing the release of air pollutants with combustion flue gases emitted to the atmosphere by the removal of one or more of nitric oxide, sulfur trioxide, light hydrocarbons, carbon monoxide, and trace amounts of mercury from combustion flue gas streams. The method converts nitric oxide to nitrogen dioxide, sulfur trioxide to sulfur dioxide, removes light hydrocarbons in the form of carbon dioxide, reduces the concentration of carbon monoxide, and removes mercury vapor in the form of mercury oxide, by the addition of hydrogen peroxide or a mixture of hydrogen peroxide and methanol to a combustion flue gas at a temperature in the range from about 650 K (377.degree. C.) to 1100 K (827.degree. C.).
摘要:
Methods for reducing NO.sub.x emissions from stationary combustion systems having variable flue gas temperatures are disclosed. Use of an annonium salt of an organic acid enlarges the temperature window for effective selective noncatalytic NO.sub.x reduction thereby accounting for variable flue gas temperatures. Currently preferred ammonium salts of organic acids include ammonium formate, ammonium acetate, and ammonium oxalate. Mixtures of urea and either an ammonium salt of an organic acid or a metallic salt of an organic acid provide an even greater temperature window for NO.sub.x reduction. Currently preferred metallic salts of organic acids include Ca(COOH).sub.2, Ca(CH.sub.3 COO).sub.2, Ca(C.sub.2 H.sub.5 COO).sub.2, Mg(COOH).sub.2, Mg(CH.sub.3 COO).sub.2, and Mg(C.sub.2 H.sub.5 COO).sub.2.
