Our company has recently installed a new 2t/h gas-fired steam boiler, which has been in operation for over a month now. The water inside the boiler is very turbid, appearing earthy yellow in color, and the iron ion levels are high. What could be the cause of this, and how can it be resolved?
The material of the boiler is iron; when iron comes into contact with water and air, an oxidation reaction occurs, resulting in rust. Rust is yellow in color. It is necessary to soften the water, remove oxygen from it, and carry out regular slag removal.
Add it before feeding water?. Also, when flushing the water level gauge, the water that flows out contains sediment
Add before feeding water. The presence of sediment when flushing the water level gauge suggests that one possible cause is poor quality of the feed water, while another possibility is the chemicals added for water treatment and their reaction products.
Is it a quick-install furnace? Generally, a new boiler needs to be boiled once to get it running, after which waste water should be removed frequently, and attention should be paid to the iron content in the condensate water
It is now three discharges per 12 hours
The water supply needs to be deoxygenated, and waste water must be removed promptly (from the water tank and boiler drum). For a small boiler like yours, the main thing to focus on is waste water removal; since the boiler is so small, it rarely comes equipped with a dedicated deoxygenator
I still don’t understand the situation of your boiler just by you saying that it runs 3 times in 12 hours. It would be better if you could specify the type of boiler, provide a system diagram, indicate the type of water replenishment, and let me know whether there is a deaerator present. Also, information on the proportion of recycled return water and the quality of the water will help in analyzing the specific causes more accurately
