Abstract

The invention discloses a boiler deoxidizer and application thereof. The boiler deoxidizer comprises acetone oxime, carbazide, diacetylmonoxime and deionized water and respectively comprises the following raw materials in percentage by mass: 8-15% of acetone oxime, 10-25% of carbazide, 15-25% of diacetylmonoxime and the balance of deionized water. The boiler deoxidizer disclosed by the invention is capable of rapidly reacting with dissolved oxygen in water, has the characteristics of being small in usage amount, high in deoxidizing efficiency, non-toxic, free in environmental pollution and thelike, does not influence salt content in boiler water after decomposition, is an optimum medicine for shutdown protection and passivating treatment of a subcritical boiler, and is also an ideal product for replacing the traditional chemical deoxidizer in medium and high-pressure boiler water supply. The boiler deoxidizer disclosed by the invention can be applied to boiler water supply deoxidizingin refinery enterprises.

Description

technical field [0001] The invention relates to the technical field of boiler oxygen scavenger, in particular to a boiler oxygen scavenger and its application. Background technique [0002] Industrial boilers, power plant boilers, refinery boilers, steam drums, and other thermal equipment work with water and steam. Corrosion of boiler feed water systems is the main cause of boiler accidents and economic losses. Equipment or component damage caused by corrosion , Maintenance time and labor, device shutdown, and even serious losses caused by safety accidents are huge. Dissolved oxygen in feed water is usually the main cause of thermal equipment corrosion. The main source is that boiler feed water or condensate leaks into the air during cycle operation, and the seal of steam turbine or condensate pump is not tight. It can lead to during operation and outage. Oxygen corrosion during the period, in order to prevent and reduce the oxygen corrosion during the operation of the boil...
