Why the Corrosion of Gas Hot Water Boiler Occurs

Why the corrosion of gas hot water boiler occurs


Generally speaking,gas hot water boiler is mainly used for heating as a typical environmental protection industrial boiler.In actual use process,the boiler corrosion will increase the cost of replacing equipment,so the enterprises using boilers need to know the reasons why the corrosion of gas hot water boiler occurs,this text will analyze that from the following aspects:


Not controlling the water supply


According to the provisions of the hot water boiler,the leakage amount of hot water systems is generally not more than 1% of the system water capacity.But some units use the hot water of system for bathing,washing clothes,and so on,a 2.8 MW hot water boiler needs nearly 100 tons of water supply a day.


Unqualified boiler water


Specified in the standard,when the water temperature is lower than 95 ℃,the PH value of circulating water should be controlled in 10 ~12,this is a very important indicator,But in the actual use of the gas hot water boiler,the water quality doesn't meet the above requirements in most cases.


without boiler maintenance after the end of the heating period


When the heating period is over,the gas fired hot water boiler for heating will face shutdown,but some boiler is filled with demineralized water,some boiler is exposed to the atmosphere,which lead to the corrosion of gas water boiler.


ZG gas fired hot water boilers have won the high praise from customers at home and abroad because of its advanced processing technology,strict quality control and long service life.One of the best examples is WNS gas water boiler,if you want to know more about that,do not hesitate to browse the webpage or contract us!
