Energy saving is very important for oil-fired and gas-fired boilers, which is related to the operating cost of the company's investment in the boiler. Zhengzhou Fangkuai Boiler Factory has summarized the following technical measures that can make fuel and gas boilers more energy-saving for your reference and application.
1. The boiler should make full use of variable frequency speed regulation technology. When the boiler water pump and fan are selected, a certain margin is considered in the rated load. Therefore, in fact, when the boiler is running, the flow rate of the fan and the water pump is less than the rated flow rate of the equipment, and they need to be adjusted. In the past, adjustments were all based on throttling, that is, closing the opening of the inlet and outlet throttle valves or baffles to reduce the flow rate, but the motor power did not decrease significantly. Frequency conversion speed regulation is to reduce the speed of the motor through the inverter, and the output power of the motor is reduced. Variable frequency speed regulation is used for fans and water pumps, which can generally save 30% to 40% of electricity. Its investment can be recovered after two heating seasons. At the same time, due to the reduced speed operation, it reduces mechanical wear, extends bearing life, and improves mechanical reliability. sex.
2. Reasonably use the automatic control technology of the boiler. During boiler operation, automatic control can improve boiler efficiency and save energy. In recent years, automatic control and microcomputer monitoring technology have developed rapidly. There are many automatic control devices for the water level of the drum and the water supply. The automatic control and microcomputer control of the combustion process are more commonly used in oil and gas boilers. For layer burning furnaces, some boilers The room is monitored by a microcomputer, and manual adjustment has also received good results. The automatic control of the boiler and the microcomputer monitoring instrument should be based on the principle of simplicity and practicality.
3. Adopt condensing waste heat recovery boiler technology. In traditional boilers, the exhaust gas temperature is generally 160-250°C, and the water vapor in the flue gas is still in a superheated state, and it is impossible to condense into liquid water and release the latent heat of vaporization. As we all know, the boiler thermal efficiency is calculated based on the low calorific value of the fuel, without considering the heat loss of the latent heat of vaporization in the high calorific value of the fuel. Therefore, the thermal efficiency of traditional boilers can only reach 87% to 91%. The condensing waste heat recovery boiler reduces the exhaust gas temperature to 50-70°C, fully recovers the sensible heat in the flue gas and the condensation latent heat of water vapor, improves the thermal efficiency, and the condensed water can also be recycled.
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.
