Abstract:

The operation situation of the steam boiler of a factory is as follows:its pressure is 1.25 MPa and the amount of steam is 19 t/h, but the boiler deaerator is not open. The boiler is used for providing steam for staff canteen laundry and heating in winter. By adding boiler deoxidizing agent, scale inhibitor and condensed water corrosion inhibitor, the corrosion on water-cooled-wall, the corrosion on the pipes of scaling and steam, and on the return pipes of condensate are effectively controlled. The chemicals in use for more than a year have been running well and passed the annual inspection successfully.

Key words: low pressure steam boiler, boiler deoxidizing agent, boiler scale inhibitor, condensed water corrosion inhibitor
