The Energy Saving Research On Gold East Paper Self-provided Power Plant

With increase of paper industry, the production of China ranked first in the world.Coal consumption in Gold East Paper approached 1 million tce/year. Energy cost became to be the biggest percentage of total cost excluding the pulp, in 20%.Combining heat and power(CHP) generation technology produces electricity and steam in multistep energy usage. Fuel chemical energy converted to steam in boiler, turbine generator generates electricity, and the process steam is extracted for papermaking. Since the cost of CHP shared equally in the main products, the enterprise management lack of overall concept for energy saving, CHP is under less pressure than public power plants.According to the Cause & Effect Diagram, energy audits and energy balance tools, benchmark the specific power plants. All the process of storage, conversion and conveying are observed to improve the energy efficiency of CHP in both equipment and management.To modify the single energy structure, in accordance with the national energy policy, some explores of the straw, straw and other biomass fuels are researched.
