FTV-A type electric furnace flame monitoring device
The FTV-A type electric furnace flame monitoring device uses the motor as the power source to drive the rack and pinion drive, and the operator can control the advance and retreat movement of the optical transmission mechanism in the central control room or on-site control cabinet. This type of device has a self-protection function, that is, when the periscope tube loses air-cooling protection or overtemperature, the optical image transmission mechanism will automatically exit the furnace, thereby protecting the safe operation of the device. In addition, this device can be connected to the plant-wide closed-circuit monitoring system and DCS control system, and the operator can also monitor and control it through the above two systems.
FTV-A electric furnace flame monitoring device has the advantages of clear imaging, reliable operation, convenient installation and maintenance, and has been widely used in petrochemical and electric power fields.
Main technical parameters
Observation field range: 50 °, 90 °, 105 °, 120 °;
Lens angle: 0 ° (direct view), 45 °, 60 °;
Working environment of protective cover:-40 ℃ ~ 70 ℃;
Heat-resistant temperature of lens: ≤ 2000 ℃;
Parameters of air source required by the device:
Wind pressure of wind source ≥ 0.3Mpa;
Wind source flow ≥ 0.3m3/min；
Air temperature ≤ 40 ℃, dust particle size ≤ 10 μm;
Oil content ≤ 10 mg/m3;
Working power supply: AC 220V, 50HZ, 300W;
Way of advance and retreat: electric advance and retreat;
Automatic exit conditions;
When the wind pressure at the protection wind inlet of the periscinent tube is lower than 0.04MPa, the image transmission system automatically exits the work site;
When the temperature in the protective cover is higher than 70 ℃, the image transmission system automatically exits the work site;
Weight of the whole machine: 43.5kg (on-site probe part).
Installation method: welding;
