Description
technical field [0001] The invention relates to a tail heat absorbing device of a saturated steam boiler, which belongs to the field of flue gas denitrification equipment. Background technique [0002] Nitrogen oxide (NOx) is a gas produced by the oxidation of nitrogen during the combustion process. It not only stimulates the human respiratory system, damages animals and plants, and destroys the ozone layer, but is also one of the main substances that cause the greenhouse effect, acid rain, and photochemical reactions. First, the boiler denitrification equipment is the equipment that removes nitrogen oxides in the combustion flue gas. Contents of the invention [0003] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a heat absorbing device at the end of a saturated steam boiler to effectively control the generation and emission of NOx during the combustion process and ensure sufficient reaction time between the reducing agen...
