干式排渣系统优化设计研究与应用

Optimization Design Research and Application Of Dry Bottom Ash Handling System

文章通过对干式排渣系统进行优化设计研究,首次提出并设计了局部分体式钢带输渣机,并采用锥齿啮合技术的炉底破碎/关断装置,提高了超大渣块的预破碎能力等,彻底解决了细渣堆积对清扫链的恶劣影响。该装置采用工业计算机控制系统,自动化程度高,大大地提高了渣系统运行可靠性,在运行、维护、检修等费用方面具有显著的优势,节能环保、增收节支效果明显,既可用于新建电厂,更可用于运行机组渣系统的改造。本技术已获多项授权发明专利,并已在国内、外燃煤锅炉机组排渣系统中获得广泛应用。

This paper studied the optimization and design of the dry bottom ash handling system. It presented and de- signed the partially split-type steel-beh conveyor for the first time, and the design also adopted the furnace bottom crush/turning off devices based on the bevel engaging technology. It improves the pre-crnsh capacity of the big clink- er and thoroughly solves the negative influence of the fine ash accumulation on cleaning chain. This device uses the industrial computer control system with high automation, greatly improving the ash system＇ s reliability. It has signifi- cant advantage of cost effectiveness during operation,maintenance and service. It has also the features of energy sav- ing,environmental protection,income increasing and cost reducing. It can be used in either newly-buih power plant or the modification of the ash system of the existing units. This technology has obtained several property rights and been widely used in the ash handling systems for the coal fired boiler units in China and other countries.
