Energy consumption trends and energy consumption in modern mills in forest industry

Technical Report:

Abstract

The objective of this study is to research the heat and electricity consumption trends in forest industry and determine corresponding figures to a modern pulp and paper mill. The energy efficiency in energy consumption and production as well as new concepts of energy supply in the modern mill is studied. Typically, energy efficiency is measured by specific energy consumption. The energy consumption is highly influenced by the technology employed in the mill. In addition to the technology specific features there are also grade specific or geographical specific features. In general in chemical kraft pulp a softwood has a higher energy consumption than a hardwood because of a lower yield. The specific heat and electricity consumption has decreased in chemical pulp grades and paper grades but increased in all mechanical pulp grades because of increased pulp quality requirements. A state of the art pulp mill is self-sufficient in energy production and even has a considerable amount of power for sale if there is a bio mass fired boiler and power production is done in a condensing turbine with multiple extractions for process steam. In intergrated pulp and paper mills the energy self-sufficiency of the mill depends strongly on its production structure.  More>>

In TMP based paper production the electricity demand is high and the primary steam demand is low. (orig.)}
