Abstract
Seawater desulphurisation is one of the important desulphurisation methods for coal-fired power plants in coastal areas,compared with the traditional limestone wet desulphurisation,the system is simpler,but affected by regional and climatic differences,the seawater temperature is low when there is desulphurisation seawater is higher than the amount of seawater in the circulating water,aeration effect is poor and other issues,resulting in the economy of desulphurisation is high,especially in the northern coastal power plants in the autumn and winter seasons.This paper describes the seawater desulphurisation project of a new power plant unit in Zhoushan area in the east-central coast of China,combining its seawater characteristics from seawater,flue gas,equipment and other factors,through the optimisation of the absorption tower water intake,the flue gas depth of the use of waste heat and high-power equipment frequency regulation,etc.,to achieve the depth of energy saving in the desulphurisation system.关键词
