微油点火技术在国家提倡节能、环保的情况下,它以其节油高、系统简练、投资少、环保且于DCS系统对接简单等特点,微油冷炉点火和超低负荷稳燃技术是用微量的油(20～40kg/h),通过专门设计的燃烧器,点燃大量的煤粉(2～12t/h),从而达到锅炉冷炉微油点火、低负荷和超低负荷稳燃的目的。基于以上特点得到广泛的应用。现介绍微油点火技术的工作原理、技术特点及微油点火技术自动控制系统与FSSS、DCS接口设计。该技术在华能北方联合电力临河热电厂应用后,节油率得到了提高。
Micro-oil ignition technology in the country to promote energy-saving, environmental protection, with its high fuel economy, system concise, less investment, environmental protection and easy docking in the DCS system and so on, micro-oil-fired furnace ignition and ultra-low load steady combustion technology is With a small amount of oil (20 ~ 40kg / h), through a specially designed burner, lit pulverized coal (2 ~ 12t / h), so as to achieve the boiler cold oil ignition, low load and ultra-low load stable combustion purpose. Based on the above characteristics have been widely used. Now introduced the working principle of micro-ignition technology, technical characteristics and micro-oil ignition technology automatic control system and FSSS, DCS interface design. The technology in Huaneng North United Power Linhe Thermal Power Plant applications, saving rate has been increased.
