Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The Company’s effective tax rate is 0% and 2% for the six-month periods ended June 30, 2017 and 2016, respectively. The Company's effective tax rate differs from the statutory federal tax rate of 34% for the three- and six-month periods ended June 30, 2017 primarily due to a full valuation allowance recorded on our United States, China and Italy deferred tax assets since we cannot anticipate when or if we will have sufficient taxable income to utilize the deferred tax assets in the future. Further, our effective tax rate differs from the statutory federal tax rate due to state taxes, differences between U.S. and foreign tax rates, foreign losses incurred with no related tax benefit, non-deductible commissions, and non-deductible meals and entertainment expenses for the three and six month periods ended June 30, 2017 and 2016, respectively. Fuel Tech had no unrecognized tax benefits as of June 30, 2017 and December 31, 2016.
