1. Introduction

The Logika Technologies Furnace Camera System, is designed for use in steel, aluminum and

other metal mill production lines, allowing operators to observe materials in furnaces. It can

also be used to monitor combustion in power and boiler operations. It includes a rugged

enclosure protecting a high resolution camera and will withstand the harsh ambient conditions

present in heavy industrial environments.

The Unit includes water cooling and air purge to enable the camera to work in the hostile

environments around industrial furnaces. Temperature sensors and an Automatic Retraction

System provide insurance against overheating and the local electrical and pneumatic panels

simplify installation.

Applications include:

� Steel – Blast, Melt and reheat Furnaces

� Cement – Clinker Cooler, Rotary Kiln

� Power Generation – Combustion Monitoring

� Glass – Float Glass Line

� Waste Combustion – Grate Firing

� Clay and Ceramics – Kiln Monitoring

2.3 Confirmation of Camera Field of View

Calculation Formula for Field of View:

Where:

f= (focal length of pinhole lens) = 3.5 mm

H = (height of field of view) (m)

W = (width of field of view) (m)

L = (the distance between the lens and target) (m)

h = (1/3” height of camera sensor) = 3.6 mm

w = (1/3” width of camera sensor) = 4.8 mm

L(m) 3.5 4 4.5 5 6 7 8 9 10

H (m) 3.6 4.1 4.6 5.1 6.2 7.2 8.2 9.3 10.3

W (m) 4.8 5.5 6.2 6.9 8.2 9.6 11.0 12.3 13.7

In order to maximize the proportion of the monitored target in the monitoring image, it is

suggested to bore the hole on the furnace wall as near to the monitored target as possible.

3.2 Installation and Mounting Notes

1. The pitch angle should be confirmed on ordering.

2. After the equipment is installed for the air supply to the furnace door, the user should tie in

G 1/2” pipe for laying to the FCS. The air inlet to the filtration tank should be 0.5 m away

from the filtration tank and G1/2” outer thread is remained.

3. The standard distance between the pneumatic control box and auto-retract device is 2 m;

additional pipe is necessary if the distance is greater.

4. The pipeline inside the dashed frame in Figure 3.1 is to be provided by the customer.

5. Bore 140 mm hole in furnace wall, with a flared opening toward the interior.

6. The embedded parts should be welded and fixed to the outer skin (steel plate) of the furnace

wall and full welding is required. The ceramic pipe and the hole gap on the furnace wall

should be filled with fire clay.

7. For proper installation and operation of this equipment, a 500 mm clearance radius around

the center of the bored hole is required

8. Bolt or weld the Electric and Pneumatic Control Panels solidly into place close to the Auto-

Retract Device but out of the way for maintenance operations.

9. Required Air Pressure: 0.1-0.7MPa

10. Required Air Flow: 0.1-0.4 m3/min

11. Required Air Temperature: ≤ 35oC

12. Temperature inside the furnace: ≤ 2000oC

13. Air source: compressed air

14. From Figure 3.1: Cables (1), (2), (3), (4) should be provided by the customer.

(1) Video cable SYV 75-5 (RG-6)

(2) Control cable RVV 10×0.5

(3) (4) power cable RVV 3×1

(5), (8), (9) are the (included) cross-over pipes of the equipment with G 1/4” fittings.

(6), (7) are the (included) connecting cables of the equipment.

15. The customer installs G 1/2” rigid pipe for the cooling water to within 0.5 m of the

embedded parts, terminated with a shutoff with G 1/2” male fitting. Similarly, the

customer installs G 1/2” rigid pipe for the cooling water return to within 0.5 m of the

embedded parts, terminated with a shutoff with G 1/2” male fitting.

16. Before the air is applied to the equipment, close shutoff valves S1 and S2, open S3 and S4

for ventilation. After the pipes have been completely blown out, close S3, S4 and open S1,

S2. The equipment is then ready for normal operation.

4. Operation

4.1 Controls

The Control Box will be located with the monitor in the Control Room. It will allow the operator

to retract or insert the camera probe at will.

5. Maintenance

5.1 Regular Maintenance

� Diagnostics- Normally, the FCS does not require maintenance at a fixed period. Regular

attention to the following will ensure steady operation of the sensor:

� Lens Cleaning- Routinely check the FCS sensor’s pinhole lens for dust or oil residue. Open the

lens shield at the front of the sensor by unscrewing the fastening hardware on the shield and

clean the lens with alcohol and lens paper or lint-free cloth.

� Detector- The pneumatic filters should be inspected and replaced as necessary according to the

plant maintenance schedule.

5.2 Returns of the FCS

� Contact us with the Serial Number of your sensor before you return our product. If we are

unable to solve the problem by phone or email, we will then provide you with a return

authorization number.

� Do not return the FCS without an authorization number.

� If the product is out of warranty, we will provide a repair estimate and then complete the

repairs after your approval.
