世界杯足球买球’s family of paper machine ventilation processes and products goes under one name – OptiAir. The OptiAir family is a complete energy-efficient set-up for paper and board machine process ventilation. 这个家族包括OptiAir兜帽, OptiAir复苏和OptiAir环境流程和产品.
在纸和纸板制造过程中, 原材料等资源, 水和能源, 必须以比今天更有效的方式使用吗. A spotlight has been put on energy consumption – energy will continue to be a significant factor, 影响整体生产成本. Any improvement in decreasing energy consumption will immediately pay back as a more profitable operation and decreased CO2 排放. OptiAir process ventilation solutions provide excellent opportunities for reducing costs and increasing the profitability, 无论是新机器还是旧机器.
The energy used in the paper drying and evaporation process is bound in the exhaust air. 在那之后, the process ventilation and heat recovery functions practically define the total energy efficiency of the machine.
Once a huge amount of energy has been used for drying, the energy doesn’t disappear. The energy in the steam used in the cylinders is released by condensing the steam. Then this energy is transferred through the cylinder cell into the paper sheet. The steam energy will be bound in the evaporated water and finally all the evaporated water with energy from the steam will be in our exhaust air. 实际上, we have more energy in the exhaust system than in the steam flow into the cylinders, 因为在进入的供气流中已经有相当多的能量. 在一台现代的纸或纸板机中，可以回收超过50mw的热量. 有效利用这种能量是很重要的.
Significant energy content exists not only in the dryer section but also in other process exhausts such as the vacuum system exhaust and the exhaust air of coating dryers. In practice, there is enough energy in the process exhausts for all water and process air heating. Machine hall heating in cold regions can be also done with this secondary energy.
全球已经制定了节能目标, 二氧化碳的减少和更好的能源效率. 能源也是造纸和纸板生产中最大的成本之一, 但世界杯足球买球也给造纸商带来了好消息! 在节约能源方面仍然有很大的潜力.
通风过程 systems provide exciting new opportunities for reducing costs and carbon footprint and increasing profitability. 然而, these opportunities need to be investigated – simply because the systems are running, 造纸, 不假设它们正在有效地运行. 你必须寻找机会，它们就在那里!
2019年，阿金P&P decided to rebuild its paper machine PM 2 with a target to increase the mill’s production and improve the end-product quality. The rebuild was delivered by 世界杯足球买球 and it included OptiAir复苏 mist remediation to reduce and eliminate mist and enable the increase of heat recovery capacity.
在现代纸机或纸板机中, the effect of heat reclaimed from dryer section exhaust air can translate to over 40 MW of energy saved during periods of peak heating. But the benefits of effective heat recovery are by no means restricted only to such cases, 自, 在实践中, 在任何时候都可以达到显著的节省. A recent heat recovery system rebuild at SCA Packaging’s Obbola PM 1 kraftliner machine in 瑞典 yielded energy savings of over 11 MW.
