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.
