Gas hot-blast stove is an industrial hot-blast stove burning clean energy and natural gas. With the implementation of the national coal-fired rectification policy, this kind of hot-blast stove is gradually favored by the market and becomes an efficient energy-saving and environmental protection industrial thermal energy equipment. In order to prolong the service life of the hot blast stove, the water quality entering the hot blast stove needs to be treated. What are the measures for water treatment of the gas hot blast stove? The relevant engineers of Zheng Guo, the pilot enterprise of the industrial hot blast stove, give the following opinions: 化学除氧剂
Chemical deoxidizer is composed of organic and inorganic components such as corrosion inhibitor, penetrant and oxygen absorbent. It can effectively absorb dissolved oxygen in hot blast stove water and prevent the corrosion of dissolved oxygen to hot blast stove metal. Moreover, the products of chemical reaction have no harm to hot blast stove.
Water supply alkali reducing agent
The feed water alkali reducer is composed of organic and inorganic components such as high efficiency corrosion inhibitor, alkali reducer and catalyst. It can effectively reduce the alkalinity of feed water of hot blast stove, increase the concentration multiple of pot water, reduce the discharge of hot blast stove, and obviously increase the Coal-Steam ratio and water-steam ratio. It is suitable for low pressure steam hot stove with high alkalinity of feed water and low chloride content.
Steam Condensate Water Treatment Agent
Steam condensate water treatment agent is composed of organic and inorganic components such as high efficiency corrosion inhibitor, acidity and alkalinity regulator, organic surfactant and film-forming agent. It has strong permeability and can effectively inhibit the corrosion of metal by acid water. It can purify steam, regulate the quality of condensate water and prolong the service life of equipment and pipeline.
Corrosion and scale inhibitor
Inhibitors and scale inhibitors generally consist of organic and inorganic components such as highly effective corrosion inhibitors, penetrating agents, dispersants, alkalinity regulators and catalysts. Complex physical and chemical reactions in hot blast stove water at high temperature can effectively prevent scale formation on heating surface of hot blast stove and prevent hot blast stove corrosion.
