给水加氧（Water and oxygen）.doc

给水加氧（Water and oxygen） The condensate conductivity is less than 0.15 with oxygen, two oxygenation points: low pressure (condensate treatment), high pressure (deaerator). To stabilize the iron ions. Because the dc furnace does not discharge, the evaporation point depends on the front, so oxygen, the most advanced technology. Boiler feed water and oxygen treatment technology and its application on the 1021t/h boiler Jilin electric power 2003 03 Liu zhihua shengchunlin (shuangliao power plant jilin shuangliao 136400) ma wenjing (suzhou thermal engineering research institute jiangsu suzhou 215004) Abstract: in this paper introduces the principle of water and oxygen treatment, based on the detailed analysis of the factors affecting the formation of oxide film, and introduced the first subcritical pressure boiler in our country (1 0 2 1 t/h) for feed water treatment with oxygen test experiment preparation conditions, after treatment, water supply and oxygen operation specification, main control targets and finally compare the technical indexes and economic benefit. Key words: subcritical pressure boiler. Water feed treatment. Double layer oxide film.

Date of collection: 2003-02-25 Feed water treatment with oxygen is the boiler feed water treatment technology developed in the 1970 s, it has to do with water supply oxygen in opposite directions, is in the high purity of boiler feed water in just the right amount of oxidant (usually a gaseous oxygen), while adding a trace of ammonia which can adjust the feed water quality. In order to further reduce the unit water, steam and heat loss, reduce the thermal system scaling, corrosion and salt deposition rate, improve the overall running efficiency and safety, lengthen the operation cycle of the condensate polishing
