Condensing gas boilers play an important role in many industries and fields. Due to the excellent performance of the boiler itself, it also has a high reputation and evaluation among users. Everyone knows that condensing gas boilers are very easy to use, but "easy to use" is based on correct use. Zhengzhou Fangkuai Boiler Factory will briefly introduce some precautions when using condensing gas boilers.
1. Precautions before using condensing gas boiler
Before installing the condensing gas boiler, you should strictly follow the manufacturer's instructions and use the specified additives (neutral acid and alkali cleaning agent) to clean the pipeline system. Since the condensing boiler is made of silicon-aluminum-magnesium alloy, if the water supply is strongly alkaline during use, the boiler may be corroded. Therefore, according to regulations, the H value of the boiler's water supply must be within a certain range of values.
2. Matters needing attention in the process of using condensing gas boiler
When using a condensing gas boiler, a filter must be installed, otherwise the boiler will be damaged. Before the boiler runs, the water must be circulated for a certain period of time to remove impurities in the system. After the operation of the condensing gas boiler is completed, the safety discharge valve must be opened to remove impurities; and the system return pipe of the condensing gas boiler also needs to install a filter to prevent impurities or sludge from blocking the system and damaging the boiler.
3. Precautions after using condensing gas boiler
After the condensing gas boiler is in use, it needs to be maintained and maintained as required, and any problems are discovered and resolved in time to avoid further damage to the system. If it is a new system using a condensing gas boiler, it should be flushed sufficiently to remove the flux, grease, metal chips and other residues generated during installation; if the old system is used, it should be noted that it should be flushed again to ensure that metal oxides and other corrosive properties are removed Residues, to ensure that all low points in the system are emptied.
Recently, Zhengzhou Fangkuai Boiler Sales Co., Ltd. traveled to Dhaka, the capital of Bangladesh, to attend the Bangladesh International Textile, Knitwear & Garment Industry Exhibition (BTKG 2026). It showcased industrial thermal equipment and system solutions adapted to the whole process of textile printing and dyeing, actively expanding the South Asian market.
