For the gas boiler, sewage is a very important operation step, the natural gas boiler drainage is an important link to ensure that the use of continuous sewage discharge discharge of some salt dissolved in water, in order to maintain the boiler water salinity, alkalinity. Emissions are continuously expelled from the evaporation surface, which has the highest salt concentration in the pot water, also known as surface drainage.
Gas boiler sewage is also certain requirements and operation sequence, specific let Zhengzhou fangkuai boiler factory technical engineers to tell you the answer.
1. When sewage is discharged, it must be of high water level and low load (small external load). Steam pressure ≤kg/c; After the water level pump is started, replenish the furnace water to the high water level, and put the pump rotation button in the automatic position.
2. Open the quick discharge valve first, then open the slow discharge valve (slowly) to discharge; Switch between quick discharge valves several times (oscillate from bottom of furnace, discharge with water).
3. The pump will start (light) automatically in the sewage process and stop. First, close the drainage valve. When the quick drain valve is closed, hands must not be removed from the lever. Sewage may be repeated. When only two fixed drain valves are installed and no quick drain valves are available, open the right Angle valve first and then the fixed valve. When closed, note that there is no residual pressure between the two drain valves. Two methods of sewage. But the same furnace must be consistent, not one method today, tomorrow, one method, in order to protect a drainage valve in good condition, ensure safety.
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.
Bangladesh is an important global producer and exporter of textiles and garments. As a pillar local industry, the textile sector has long-term and strong demand for high-efficiency, stable and energy-saving industrial boilers and thermal equipment, with broad market potential. This exhibition participation is an important measure for Zhengzhou Fangkuai Boiler Sales Co., Ltd. to advance its internationalization strategy and further explore overseas markets.
Relying on its technological accumulation and manufacturing advantages in the field of thermal energy equipment, the company provides targeted thermal energy solutions for local textile, printing and dyeing, garment manufacturing and other industries, helping enterprises improve production efficiency and reduce operating costs. In the future, Zhengzhou Fangkuai Boiler Sales Co., Ltd. will continue to focus on overseas market demands, continuously optimize its product and service system, facilitate the high-quality development of the global textile industry with professional and reliable products, and steadily enhance the brand’s competitiveness and influence in overseas markets.
Trust stems from quality
At the beginning of the new year, Fangkuai Boiler and a leading domestic new energy company have reached another important cooperation, successfully signing an order for a total of 500 steam tons.
