Saving Energy And Reducing Consumption Of 1000 Mw Ultra-supercritical Technology Application Research

With the process of China’s industrialization, the towns and the consumption structure upgrading, the resource constraints in China is becoming more and more intensive, energy-saving emission reduction situation is very grim, save and intensive use of resources, bring about a fundamental change in resource utilization, strengthen the conservation management of the whole process, is the basic way to maintain the sustainable development of China’s economy.Large capacity mature technology of supercritical and ultra-supercritical units will be the main development direction of clean coal power generation technology in China, but also to solve the power shortage, energy efficiency and low environmental pollution, the most practical and most effective way.The Zouxian Power Plant two sets of one million kilowatts of units, is the national "eleven five" key construction projects and "863" plan ultra home-made supercritical units depending on the project, in2005started construction in January,2006December and2007July put into production.Two units since the operation, running in good condition, the economic indicators to meet the design requirements, and achieved remarkable economic and social benefits.In recent years the Zouxian Power Plant has always put energy saving as an important daily work, rely on progress of science and technology, strengthen management, and constantly explore new methods, new way of energy saving, energy saving achieved remarkable results. The Zouxian Power Plant two million-kilowatt units, as is the Dongfang Electric Group’s first construction units, with the development of energy saving technology, aiming at the key energy-saving technology of1000MW ultra-supercritical unit after the commissioning of the applied research, provides the energy saving experience and reference for the follow-up of ultra supercritical unit selection.This paper mainly through the operation optimization and transformation of condensate pump, boiler sootblowing optimization test, reduce carbon boiler slag, rotary air heater, the positive pressure direct blowing type low speed coal mill start-stop without oil, winter single pump operation for applied research, through analysis and calculation, think Zouxian Power Plant one million units using energy-saving new technology is feasible, technical indicators can significantly optimize unit.
