摘要: Abstract The emission of NO x from coal-fired boilers can be limited by means the selective catalytic reduction with ammonia. amounts unreacted ammonia downstream should low to avoid processing and environmental problems. Continuous measurement in flue gas is needed. determination sampling techniques are discussed. Measurements exhausts a laboratory reactor pilot plant for presented. Ammonia was determined mass spectrometry chemiluminescence phase, spectrophotometric (Nessler Berthollet reactions) or potentiometry aqueous solution, ( −1 ) high concentration ranges.
