摘要

摘要可编程逻辑控制器(PLC)是一种微控制器系统,适用于许多工业流程。本项目旨在通过设计和实施 PLC 系统,调节锅炉用水的 ph 值和总溶解固体(TDS),从而提高蒸汽锅炉的性能和能效。该系统有助于保护锅炉管免受结垢和沉积物腐蚀,此外还能减少和控制排污水量并节约能源。实验结果表明,建议的控制器能够在总 TDS 值为 20 ppm 的情况下,通过调节电导率值为 3900 μs/cm 来控制 TDS 量。通过将 pН 保持在蒸汽锅炉全球运行框架要求的 10.3-10.5 范围内,实现了污垢控制。此外,自动排污节省了约 9.532%,系统自动排污与手动排污的差值为 81.8%,每年可节省燃料成本 1230720 美元。

Fouling and Corrosion Control of Steam Boiler Tube Using PLC system

Fouling and Corrosion Control of Steam Boiler Tube Using PLC system

Abstract

Programmable logic controllers (PLC) is a microcontroller system suitable for many industrial processes. The current project aims to enhance performance and energy efficiency of steam boiler through adjusting the ph value and total dissolved solids (TDS) in boiler water by designing and implementing a PLC system. This system contributes to protect the boiler tubes from fouling and under deposit corrosion, in addition to reduce and control the blow down water and energy saving. The experimental result showed that the suggested controller is able to control the amount of TDS through adjusting the conductivity value as 3900 μs/cm with total TDS values as 20 ppm. Fouling control is achieved by maintaining the pН within the requirements of the global operation framework of steam boiler as 10.3–10.5. Also, the automatic blow-down saves about 9.532% and the difference between system automatic and the manual process is 81.8% involved achieving an annual saving in fuel cost of 1230720 $/year.

期刊介绍: Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
