Discussion on Controlling of pressure and temperature in the course of 600 MW supercritical Boilers started

With the development of the national economy and the progress of technology,Supercritical Pressure thermal Power Plant of 600MW which made in china has already become main type of electric power networks.Transformation between wet state and dry state which exist in once-through boiler's start and stop process,and control methods in these two states are different.This paper make a study of the properties of adjusting the temperature and pressure by two controlling methods,which adopt fueling oil and starting to mill in advance to increase temperature and pressure,when 600MW supercritical and opposeed firing boiler starts and runs,which is producted by harbin boiler company limited.In addition,controlling temperature and pressure in normal running are studied in this paper.
