本文介绍采用DDZ—Ⅲ型自动化仪表对10t/h工业锅炉组成的仪表系统,并阐述了水位、炉膛负压和烟气含氧量控制系统的工作原理,并取得节能2%左右的经济效益。 一、概述 我厂原有的两台10/h锅炉为翻转式炉排煤粉炉,由于炉体结构上存在技术问题,尤其是仪表测量方面技术水平很低,运行管理全凭观察和感觉,造成能量损耗大、炉龄短、工人劳动强度大,环境污染严重。为此,在86年对其进行了技术改造。炉体改为链 This paper introduces the instrument system of DDZ-Ⅲ automation instrument for 10t / h industrial boiler, and describes the working principle of water level, furnace negative pressure and flue gas oxygen content control system, and achieves about 2% energy saving. First, an overview of our original two 10 / h boiler for the flip type grate pulverized coal stove, due to the furnace structure of the technical problems, especially the technical level of instrument measurement is very low, operation and management depends entirely on the observation and feeling, Resulting in large energy loss, short furnace, workers labor intensity, serious environmental pollution. To this end, 86 in its technological transformation. Furnace to chain
