From a professional perspective, the capacity of a steam boiler is called "tonnage," and the capacity of a hot water boiler is called "power." Learn to switch between power and tonnage, you can quickly and easily understand the parameters of the boiler.
For hot water boilers, the boiler power is expressed in MW (1MW = 1000kW) or million kcal / hour (ten thousand kcal / h).
For a steam boiler, its power is also called the evaporation capacity, which is the amount of water converted into steam per hour: ton / hour (T / h) or kilogram / hour (kg / h). Of course, it can also be expressed in MW or KW.
In China, the correspondence between evaporation and power is:
1T / h = 1000kg / h = 0.7MW = 720kW = 600 thousand kcal / h = 600Mcal / h.
Units of power are also horsepower (Hp) and boiler horsepower (BHp).
1Hp = 0.745kw, 1BHp = 9.81kw
In some European and American regions, the steam boiler evaporation capacity is often marked with "at 212", which means that its evaporation capacity refers to the evaporation of 212 degrees Fahrenheit of water to 212 degrees Fahrenheit, which means that the water evaporation at 100 ° C Amount of steam at 100 ° C. In this way, 1kg of evaporation is equivalent to 540kcal of heat. We call it "equivalent evaporation", that is: 1T / h = 540,000 kcal / h. It can also be deduced from this that the relationship between boiler horsepower and "equivalent evaporation" is: 1BHp = 15.62kg / h.
In boiler equipment, these parameters also have corresponding conversion relationships.
1 ton / hour (t / h) ≈ 60 × 104 kilocalories (kcal) / hour (kcal / h) ≈ 0.7 megawatt (MW) ≈ 720K kilowatt (KW)
2. Boiler evaporation and boiler horsepower 1 ton / hour (t / h) ≈ 71.1 boiler horsepower (BHP);
3. Boiler pressure engineering unit and international unit of measurement 1 MPa (Mpa) ≈ 10 kgf / cm2 (kgf / cm2);
4. Megapascals and Pascals 1 Megapascal (Mpa) = 106 Pa (pa) 1 Pa (pa) = 0.01mbar (mbar) ≈ 10-5 kgf / cm² (engineering atmospheric pressure) (kgf / cm2) 1 pa (Pa) ≈0.1 millimeter water column (mmH2O);
5. Force and gravity 1 kgf (kgf) = 9.81 Newton (N);
6. Calories 1 kcal (kcal) = 4.187 kilojoules (KJ);
7. Volume (volume) 1 cubic meter (m3) = 1000 liters (L) 1 liter (L) = 1000 milliliters (ML).
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.
