The Blance Of Heat Testing And Dicline Save Energy Studying About No.1 The Blast Furnace Of The Jiuquan Iron And Stell.com

The blast furnace thermal equilibrium test is effective method appraising blast furnace heat energy utilization and analysis hot worker's specific property of blast furnace;Seeking blast furnace save energy falls and consumes, raises production efficiency and raises equipment to have the great real meaning in life span; Test and analyses by way of thermal equilibrium, and providing the science basis for improving operating of blast furnace and technical transformation.Purpose that this lesson pass toJiuquan IRON & steel No.1 the blast furnace proceeds hot equilibrium test, evaluate its thermal energy make use of the level; make use of the rist operation the line, certain potential of reduse the coke of the JIUQUAN IRON AND STEEL.COM; Bring up to decline the coke measure.Pass to the the blast furnace 's hot equilibrium test of JIUQUAN IRON AND STEEL No.1, proceeds No.l the material equilibrium of the number the blast furnace with hot equilibrium calculation, lowest carbon of theories ratio calculation, the Rist curve draw. No.1 the declining of the blast furnace body of the number the blast furnace efficiency is 84.92%, the lowest carbon of theories compare to 416.65 kgs/ts, and lower the fuel the potential that compare to 83.37 kgs/ ts.Combination test calculation result, applied knowledge of related produceing iron of the blast furnace and the theories with thermodynamics theories knowledge, analyzed the wine steel the blast furnace a the in the last years make use of the aspect the acquisition in the thermal energy advance of reason. The main reason that energy utilization increase consist ins the blast furnace operation the principle's advance: Iron grade is raised; Going into stove powder content reduces. The shortcoming that the heat energy utilization aspect exists chiefly has total heat to be lost greatly; Stove dust content is high, and reaches the surplus energy of 20.97% not to be used, and the heat is lost very greatly. Putting forward save energy falls that the burnt measure has: improves reduction of furnace charge; Use large quantities of weights and many rings cotton material and the feeding system of standard-sized sheet wind gap school assignment;Adding coal gas and blast shedding the wet installation and preheating raising the wind temperature etc with carrying on hot-blast stove combustion-supporting air and coal gas. And calculate the effect of part of measure. After the measure implementation, the income stove coke ratio has reduced the synthetical coke ratio of 43kg / t, and has reduced 47kg /t.
