A reduction in fuel consumption by even 10% would effect savings of upto Rs. 11700/-
per day or approximately Rs. 35 LACS per year (at an average consumption of 45 litres
/ MT and at a production level of 100 MT per day and taking the cost of Furnace
Oil to be approximately Rs. 26/ Litre).
Scale losses and increased fuel consumption are caused mainly due to too much excess
air in the furnace due to incorrect air:fuel ratio, causing the excess oxygen to
oxidize the job in the re-heating furnace as also sensible heat being carried away
from the furnace requiring more fuel to be pumped in.
Fykays solution to the problem:-
"OXYCOMP-G" - FYKAYS ONLINE OXYGEN ANALYSER
The OXYCOMP - G works on the well–proven Zirconia sensor principle which enables
detection of Oxygen in the furnace from PPM level to 100%.
The OXYCOMP-G has been specifically developed to monitor the amount of excess oxygen
in the re-heating furnace gases. Once this is known, the user can control the Excess
air either manually (OxyComp G-I) or automatically (OxyComp G – II).
The basic components of Fykays OXYCOMP-G system are as follows:
- Oxygen Probe: The Zirconia Oxygen probe which senses the Oxygen in the furnace atmosphere
- Probe heating Furnace + Controller: A small auxiliary furnace which is installed
on the side wall of the re-heating furnace in which the Oxygen probe is installed.
This furnace temperature is controlled with the help of a PID controller.
- The Oxygen Analyzer
- The reference air system
- The electronic purging apparatus
- The remote display: The signaling panel with Hi/Lo alarm
OXYCOMP G-II FYKAYS OXYGEN ANALYZER AND CONTROLLER
Recognizing the industry requirement for automated control & reliability we have
developed the OXYCOMP G-II. Essentially, it is built around the well proven Zirconia
technique and enables precise detection and control of Oxygen over a wide range.
In addition, this version of OXYCOMP G-II utilizes an equally well proven technology
namely the Variable Frequency Drive (VFD) to regulate the speed of the main air
blower so as to reduce the air intake into the furnace which in turn controls the
excess free Oxygen ( Air )
