The paper and pulp industry is an energy and emission intensive industry. Steam is an essential part of the paper making process with steam boilers, steam distribution systems and other processes accounting for a large percentage of a paper mill’s energy costs. Useful energy is often lost from boilers and process equipment such as heat exchangers, dryers, evaporators etc, as well as from transporting steam from boilers to different areas of the plant. Although a mill may well have a cascade steam system on the paper machine(s), mechanical trap failure can needlessly elevate fuel bills and emission costs by over 20%.
