Problems solved by technology

When chemically treated with hydroxylamine groups, hydroxylamine generates acids such as nitric acid, which increases corrosion on boilers
The disadvantage of sugar production is that it is difficult to measure its residue concentration in boiler water, so it is difficult to control the correct addition amount, and sugar produces odor to steam

Abstract

A multi-component boiler deaerization agent consists of catalytic sodium sulfite 70-80wt%, 2,3-diamino-piperidine 10-20wt% and azacyclopropane 5-10wt%. It can remove dissolved oxygen, residues and scale.

Description

technical field [0001] The invention belongs to the fields of chemical industry and environmental protection, and relates to an oxygen scavenger, more particularly, the invention relates to a multi-component boiler oxygen scavenger. Background technique [0002] Oxygen scavenger, also commonly known as oxygen scavenger. In boiler components (such as the boiler body, the heat exchanger and economizer arranged at the upstream of the boiler body, and the steam and condensate pipes arranged at the downstream of the boiler body), dissolved oxygen becomes one of the main causes of corrosion. To prevent corrosion in boiler systems, it is necessary to remove dissolved oxygen from the boiler water. [0003] Currently in the prior art, chemical treatment and physical treatment are often used to remove dissolved oxygen. In chemical treatment, oxygen scavengers such as hydrazine, hydroxylamine groups or sugars have been widely used. When chemically treated with hydroxylamine groups, ...
