Preheating of furnace feed oil using PLC

摘要

Liquid fuels like furnace oil are predominantly used in industrial application. Viscosity is the most important characteristic in the storage and use of fuel oil. Viscosity influences the degree of pre-heat required for handling, storage and satisfactory atomization. If the oil is too viscous, it may become difficult to pump to light the burner as well as tough to operate which causes poor atomization. Therefore pre-heating is necessary for proper atomization as it may result in the formation of carbon deposits on the burner walls. This work presents the development of a modular temperature control system for furnace feed oil and implemented using a modern high performance PLC.
