Goodwill and Intangible Assets Disclosure [Abstract]
Goodwill and Other Intangibles	Goodwill and Other Intangibles Goodwill is allocated among and evaluated for impairment at the reporting unit level, which is defined as an operating segment or one level below an operating segment. Fuel Tech has two reporting units which are reported in the FUEL CHEM^® technology segment and the APC technology segment. At September 30, 2014 and December 31, 2013, goodwill allocated to the FUEL CHEM technology segment was $1,723 and $1,723, respectively, while goodwill allocated to the APC technology segment was $24,416 and $19,328, respectively. The $5,088 increase in goodwill in the APC technology segment is due to the acquisitions of Cleveland Roll Forming Environmental Division, Inc. d/b/a PECO ("PECO"), and FGC, Inc. ("FGC") on April 30, 2014. Both of these acquisitions were accounted for under the acquisition method of accounting, which requires Fuel Tech to perform an allocation of the purchase price to the assets acquired and liabilities assumed based on their estimated fair values at the date of acquisition. The excess of the purchase price over the estimated fair values is recorded as goodwill. The increase in goodwill reflected above is a preliminary estimate as the fair value of assessments have not been finalized. Any changes to the estimated fair values of the assets acquired and liabilities assumed may change the amount of the purchase price allocable to goodwill. Fuel Tech expects to finalize the purchase price allocation by the end of the current fiscal year. Refer to Note R to the consolidated financial statements for additional details. Goodwill is allocated to each of our reporting units after considering the nature of the net assets giving rise to the goodwill and how each reporting unit would enjoy the benefits and synergies of the net assets acquired. Our last annual fair value measurement test, performed as of October 1, 2013 revealed no indications of impairment. There were no indications of goodwill impairment in the nine-month periods ended September 30, 2014 and 2013. At September 30, 2014 and December 31, 2013, net other intangible assets were $10,616 and $4,305, respectively. The April 30, 2014 acquisitions of PECO and FGC resulted in additional other intangibles of $4,126 based on a preliminary assessment of the fair value of the intangibles acquired. Refer to Note R for additional details regarding the allocation of the purchase price for these two business acquisitions. In addition, on September 18, 2014, Fuel Tech purchased intellectual property rights and know-how associated with the CARBONITE^® fuel conversion process in the amount of $3,010, which was accounted for as a purchase of identifiable intangible assets. Fuel Tech reviews other intangible assets, which include customer lists and relationships, covenants not to compete, patent assets, tradenames, and acquired technologies, for impairment on a recurring basis or when events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. In the event that impairment indicators exist, a further analysis is performed and if the sum of the expected undiscounted future cash flows resulting from the use of the asset is less than the carrying amount of the asset, an impairment loss equal to the excess of the asset’s carrying value over its fair value is recorded. Management considers historical experience and all available information at the time the estimates of future cash flows are made, however, the actual cash values that could be realized may differ from those that are estimated. There were no indications of intangible asset impairment in the nine-month periods ended September 30, 2014 and 2013.
