Fume System Control

The main objective for a good fume control system is always to improve indoor working conditions and outdoor environment.  Historically, steel production did not require a fume system but in today’s environment, a furnace cannot operate without a fume control system, due to governmental environment and working regulations. 

A Dynamic Fume Control System is designed to address the following control issues:

Control of Furnace Draft with furnace dp and upstream off-gas analyzer – to avoid Over-Drafted (high energy consumption) and Under-Drafted situations (poor in-plant air quality working conditions)

Control of Combustion Gap Position with downstream gas analyzer – to avoid drawing too much false air which reduces FCS performance and increase maintenance levels, or drawing too little air which causes safety concerns with deflagration due to quenched combustion and excess CO downstream

Control of Combustion Flame Length with downstream gas analyzer and air injection jets - to avoid flames traveling deep into the water cooled ductwork and allowing it to perform as intended to reduce gas temperature, sensible energy.

Understanding Primary FCS Performance with continuous optical temperature and velocity measurements – trend continuous measurements to allow evaluation and adjustments to avoid high/low parameters for improved performance.  

Reduced FSC maintenance, operation cost and excessive revamping capital cost – DFCS Technology can dramatically improve combustion control efficiency and thereby significantly reduce fume system infrastructure & capital/revamping/operational cost ($$$)
