Research And Application Of Comprehensive Emission Reduction Process For Coal-fired Thermal Power Units

With the rapid development of the national economy,the contradiction of environmental pollution has become more and more serious.Since 2013,there have been a series of problems such as large-scale,long-term haze weather and acid rain in all parts of the country.Coal-fired power plants,as the emission magnifier of air pollutants,make human health and ecological environment face great challenges.In order to meet people’s increasing demand for life,How to reduce the emission of pollutants has become a key issue for the survival of thermal power plants.Industrial power plant enterprises gradually began to pay attention to the technology of desulfurization,denitrification and flue gas dedusting.Therefore,it is urgent to accelerate the emission of desulfurization,denitrification and flue gas in coal-fired power plants.Denitration this topic from coal-fired power plant desulfurization and dust removal technology present situation analysis,studies the key influence factors to emissions standard quality,from the denitration desulfurization and dedusting coupling mechanism and the relationship analysis,analysis of nitrogen oxides and sulfides of smoke flow and particle interaction relationship between dust mixture,as well as the restriction of sold out on the desulfurization effect,and then the theory of desulfurization is out of stock and dusting the core technology research,improve the system effectiveness of denitration desulphurization and dust removal technology,through the local modification,increase the efficiency of the system,so as to achieve optimal discharge atmospheric pollution treatment effect,to meet the requirements of the national quality standards to the atmospheric emissions.Keywords: ultra low emission of desulfurization;denitrification and flue gasdedusting technology;SNCR process Denitration this topic from coal-fired power plant desulfurization and dust removal technology present situation analysis,studies the key influence factors to emissions standard quality,from the denitration desulfurization and dedusting coupling mechanism and the relationship analysis,analysis of nitrogen oxides and sulfides of smoke flow and particle interaction relationship between dust mixture,as well as the restriction of sold out on the desulfurization effect,and then the theory of desulfurization is out of stock and dusting the core technology research,improve the system effectiveness of denitration desulphurization and dust removal technology,through the local modification,increase the efficiency of the system,so as to achieve optimal discharge atmospheric pollution treatment effect,to meet the requirements of the national quality standards to the atmospheric emissions.The research of this topic provides important theoretical basis and practical experience for the improvement of energy conservation and emission reduction efficiency of similar thermal power plants and the reduction of pollutant emissions,which has a wide range of promotion significance.
