Industrial boilers can provide a large amount of power output for users in the broad industrial field, but it will also be accompanied by a certain degree of danger. Therefore, when operating and using industrial boilers, certain safety regulations must be followed. In particular, the boiler operator who operates the boiler must have certain professional skills.
The heating value of a 10-ton boiler is equivalent to 6 million kcal. Therefore, if the calorific value of natural gas is calculated according to 8600 calories, then the amount of natural gas consumed per hour is about 700 cubic meters. Different boilers have different auxiliary machines.
In boiler equipment, if the different furnace types are different, then the ratio of fly ash to slag is different, so the answer to question 1 is different. For example, for a pulverized coal furnace, the proportion of fly ash is 90% and the proportion of slag is 10%. The boiler supervisor and boiler water tester must be certified to work, and must not violate this requirement.
In the waste heat boiler, if it is medium-pressure steam, the pressure is 0.93MPa and the temperature is 280°C; if it is low-pressure steam, the pressure is 0.7MPa and the temperature is 260°C. If the temperature of the condensate is too high, it needs to be cooled and treated before entering the boiler.
We, Zhengzhou Fangkuai Boiler Co., Ltd. (Fangkuai), are excited to announce our participation in the Indonesia International Heating Technology Exhibition 2025. We will be showcasing our advanced boiler systems engineered for higher efficiency, lower emissions, and sustainable energy performance. Join us at Booth No. B1-08 from November 5–7, 2025 at the Jakarta Convention Center.
The event brings together EXPO BOILER, EXPO BIOMASS, EXPO PUMPS & VALVES, and EXPO CRANE — creating a comprehensive platform for technology exchange and business collaboration across the industrial heating and energy sectors in Southeast Asia.
At the exhibition, we will present our integrated solutions including biomass boilers, industrial steam systems, and full power plant EPC services. Our products emphasize:
