Why can steam generators be used in papermaking?

The paper making process, from pulping to finished product output, cannot be separated from thermal energy support in each link, and steam generators, as high-quality steam thermal energy supply equipment, play a key role in it. Steam generators have become an ideal choice for multiple process steps in the paper making industry due to their excellent steam characteristics.In the pulping process, high-temperature steam is needed to soften the raw materials and decompose the fibers. The steam generator can quickly produce high-temperature steam and accurately maintain the temperature at 160-180°C, which is the appropriate temperature range for chemical pulp cooking. It can accelerate the softening and decomposition of lignin, efficiently separate the fibers, and greatly shorten the cooking time. However, traditional boilers heat up slowly, and it often takes about 30 minutes to achieve stable steam output. Not only is it difficult to meet the needs of efficient paper making production, it will also cause unavoidable waste of resources.Entering the paper making forming stage, the quality of paper requires extremely high stability of steam. The steam generator can provide steam with stable pressure and realize stepless frequency conversion regulation to ensure uniform steam heating during paper machine operation, optimize fiber bonding, and effectively avoid problems such as uneven thickness and strength of paper. In contrast, the steam pressure of traditional boilers fluctuates greatly, which can easily affect the quality of paper forming.The drying process is a major energy consumer in paper making, and the composite chamber micro-superheated steam generator demonstrates its outstanding energy-saving advantages. It uses a water-cooled fully premixed burner, with a thermal efficiency of more than 101.21%, a maximum temperature of 230°C, and a micro-superheated steam dryness of 100%. During drying, the composite cabin micro-superheated steam generator can meet the needs well, gradually reduce the moisture content of the paper, and prevent the paper from being overheated and brittle locally. Traditional boilers use a three-stage fire mode, with low thermal efficiency and widespread overcapacity.

From an environmental protection perspective, steam generators mostly use clean energy, such as gas. The nitrogen oxide emissions of the composite cabin micro-superheated steam generator are ≤21mg/m³, and the CO emissions are close to 0, so you can use it with confidence even if you are on the front line.

Therefore, steam generators have been widely used in the papermaking industry with their significant advantages in steam characteristics such as high efficiency, stability, energy saving, and environmental protection, which has effectively promoted the quality improvement, efficiency enhancement, and green development of papermaking production.
