25 Ton Coal Fired Steam Boiler Project for Paper Mill in Indonesia

ZOZEN Boiler supplied two 25-ton SZL series coal-fired steam boilers to a paper mill in Indonesia. This series of boilers has significant technical advantages, capable of producing high-dryness steam, which effectively reduces energy loss during heat transfer. The high-dryness steam not only delivers more concentrated thermal energy but also minimizes condensation buildup in equipment and pipelines, ensuring the stability and continuity of the production process.

The steam is widely used in the heating and drying stages of pulp, playing a crucial role in the entire paper production process. It heats the pulp and accelerates the evaporation of moisture, particularly during the drying phase, effectively removing water from the paper. This process is key to determining the quality of the paper and production efficiency. The stable supply of steam is directly related to the final product quality and the operational speed of the production line. Since the steam from ZOZEN boilers is of high dryness, the heat transfer efficiency is higher, which not only improves the paper mill’s energy utilization but also reduces energy consumption and operational costs.

Additionally, these two coal-fired steam boilers adopt a chain grate structure, where the continuously moving grate evenly feeds the fuel into the furnace, ensuring uniform fuel distribution and complete combustion. Compared to traditional boilers, this chain grate structure optimizes fuel combustion efficiency, ensuring stable heat release and preventing heat loss caused by incomplete combustion in certain areas. This design significantly enhances the boiler’s heat exchange efficiency, enabling the paper mill to consistently receive high-efficiency thermal energy, further improving the reliability and economy of the entire production process.

With its outstanding technology and customized solutions, ZOZEN Boiler helped the Indonesian paper mill not only improve production efficiency but also achieve its energy-saving and emission reduction goals, creating notable economic and environmental benefits for the customer.
