造纸工业是能耗密集型工业。每道生产工序都需要大量的蒸汽。近10年来多数国家由于一次能源(石油)和二次能源(电能)价格上升,使得造纸成本迅速增长。能源供应矛盾加重。由于各地能源供应情况不同.能源费用占成本比重为5—25%或更高。在这种情况下,节能技术和替代能源发展很快。利用生产中可用的内部能量或国内能源替代高价能源。 The paper industry is an energy-intensive industry. Every production process requires a lot of steam. In most countries in the last 10 years, due to the increase in prices of primary energy (oil) and secondary energy (electric energy), the cost of papermaking has increased rapidly. The contradiction in energy supply has increased. Due to the different energy supply situation in different regions, energy costs account for 5-25% or more of the cost. In this situation, energy-saving technologies and alternative energy sources have developed rapidly. Replace high-priced energy with internal energy or domestic energy available in production.
