Problems solved by technology

[0007] However, the method of US 4,519,990 is rather complicated and can lead to poor purification of the bypass portion of the gas, since the latter is not in good contact with the atomized suspension

Embodiment Construction

[0026] figure 1 is a schematic side view and shows the power plant 1 . The power plant 1 includes a boiler 2 in which a fuel such as coal or oil is burned. Combustion of the fuel produces hot process gases in the form of flue gases. Sulfur species contained in the coal or oil will form sulfur dioxide which will form part of the flue gas. Flue gas proceeds from boiler 2 to electrostatic precipitator 4 via duct 6 . An electrostatic precipitator 4 (an example of which is described in US 4,502,872) is used to remove dust particles from the flue gas.

[0027] The flue gas, from which most dust particles have been removed, proceeds through duct 10 to spray dryer absorber 8 . The spray dryer absorber 8 comprises a spray dryer chamber 12 and four dispersers 14 , 16 , 18 , 20 mounted at the top 22 of the spray dryer chamber 12 . Each disperser 14 , 16 , 18 , 20 includes an atomizer 24 . The atomizer 24 may be of the so-called rotary atomizer type, in which a wheel spinning at hig...

Abstract

A spray dryer absorber (8) is operative for removing gaseous pollutants from a hot process gas and comprises a spray dryer chamber (12) and a plurality of dispersers (14, 16, 18, 20) mounted at a roof (22) of the spray dryer chamber (12), each such disperser (14, 16, 18, 20) being operative for dispersing a portion of the hot process gas around a respective atomizer (24). Said plurality of dispersers (14, 16, 18, 20) comprises a central disperser (20), which is located at the centre (C) of the roof (22) of the spray dryer chamber (12), and at least 3 peripheral dispersers (14, 16, 18) surrounding the central disperser (20), each of said peripheral dispersers (14, 16, 18) being located at substantially the same distance (D) from the periphery (P) of the spray dryer chamber (12).

Description

technical field [0001] The present invention relates to a spray dryer absorber that functions to remove gaseous contaminants from a hot process gas and includes a spray dryer chamber and a plurality of dispersers mounted at the top of the spray dryer chamber, each such disperser The diffusers function to disperse a portion of the hot process gas around the corresponding atomizers, which function to atomize the absorbing liquid, and each disperser is provided with a flow guiding device, which functions to dissipate the heat The corresponding portion of the process gas provides rotational motion around the atomizer (as seen from the top of the spray dryer chamber). [0002] The invention further relates to a method for removing gaseous pollutants from hot process gases by means of a spray dryer absorber. technical background [0003] When fuels (e.g. coal, oil, peat, waste, etc.) are burned in combustion plants such as power generation plants, hot process gases are produced, ...
