The history of hot water boilers can be traced back to a long, long time ago, and steam boilers have been popularized in the past 200 years, which has a certain impact on traditional hot water boilers. If the space available for the former is small, or subject to greater restrictions, people will quickly choose the latter soon. The area required by the steam boiler is also relatively small, only 60% of that of the hot water boiler, and it does not require special renovation plans and indoor layout adjustments. The steam boiler not only has the advantage of occupying a small space, but also consumes less water in the furnace. The boiler can produce steam within 5 to 7 minutes after starting in the cold state, while the hot water boiler is about 60 minutes after starting in the cold state. Steam can only be started after ~90min.
When the boiler is out of service for a long time, shutting down must also be considered. The steam boiler embodies energy-saving advantages when it is started, and can save 5% to 11% of energy on average; while the former still has energy loss under normal and continuous operation: heat radiation and source loss through the chimney. Moreover, after the hot water boiler is out of service for a long period of time, it will take a long time to return to normal working condition.
The hot water boiler can provide a large amount of high-pressure hot water, wet steam and superheated steam, but the pressure it can achieve is only 32 bar. Under today's technical conditions, the achievable hot water temperature can reach 240°C and the steam flow rate can reach 45t/h. From the current popular point of view, the use of a fast steam boiler to provide wet steam is the most ideal solution: compared with the wet steam provided by the former (relative humidity 2% to 3%), the relative humidity of the wet steam provided by the fast steam boiler is only 0.5%, which can reduce the hazards caused by steam condensation in the steam pipeline, and has very good heat transfer performance during use.
Enough steam due to the small amount of internal water and the thinner wall thickness of the furnace body can reach the predetermined steam pressure in a short time, and the pressure value can be kept stable when the load changes. It does not need to be monitored under certain working conditions. Because the steam boiler consumes less water during operation, it is classified as Class III or Class IV in the equipment operation safety level regulations. When using a hot water boiler, when the pressure and capacity of the boiler exceed certain specifications, you must apply for a license before putting it into production.
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.
