Application of Na2SO3 to chemical deoxidization;

For deoxidization water dissolve oxygen exceed the permit standard in spray padding deoxidization vessel, we altered spray padding deoxidization to membrane deoxidization .

Experiment study on catalytic hydrogenation deoxygenation technology with Pd/ion exchange resin;

Study of Hydrazine Deoxygenation in Neutral Aqueous Solution;

Four kinds of methods of deoxygenation , such as by introduced in accordance with (he routine mam-tance of water healers, prpe networks and radiators.

The selection of appropriate deaeration and de - salting equipment and proper design of the velocity and selection of corrosion - resistant materials like 12Cr2AlMo and Cr5Mo etc can effectively control the corrosi.

This article introduces the necessary for equipping with the exhaust steam device with deaeration function in detailed,describe several arrangement structures of deaerator,and give a general instruction for the features of the exhaust steam device equipped with the surface heat exchanger.

This paper states the theory of supplying water deaeration for industry boiler and analyses the common techniques of deaeration by heating, vacuum and adsorption.

Some kinds of oxygen removal methods in hot water heating system were introduced.

There are many familiar oxygen removal methods of boiler feedwater all over the world,the advantages and disadvantages of which are analyzed.

The analysis of the techniques and characteristics of the conventional oxygen removal by heating method,vacuum method,analytical method and chemical reagent method are made and the comparisons among these methods are made too.

Proposes two solutions, the first is controlling the pH value of the complementary water and changing the deoxygenization method to solve the corrosion problem during operation, and the second is adding new efficient deoxidant of acetone oxime to solve the corrosion problem during suspending period.
