Abstract
A kind of station boiler flame detector; including fibre-optical probe, fire inspection protection sleeve pipe and cooling wind devices; cooling wind devices are made of cold air duct and cool-air hose; fire inspection protection sleeve pipe one end is connected on cool-air hose; one end is penetrated through furnace wall installing pipe in burner hearth, and in fire inspection protection sleeve pipe, key is to be equipped with a fine steel tube in fire inspection protection sleeve pipe for optical fiber setting; fine steel tube one end is connected on cool-air hose air inlet, and optical fiber is arranged in fine steel tube.Improved station boiler flame detector; it is penetrated in original fire inspection protection sleeve pipe using by fine steel tube; cooling wind pipeline is connected; optical fiber penetrates in fine steel tube; to ensure that fibre-optical probe is not burned; maintenance cycle is extended, maintenance cost and maintenance time are saved, ensure that the safe and stable operation of unit.
Description
Technical field
The utility model is related to a kind of station boiler flame detectors.
Background technology
Be required for the combustion case of monitoring boiler furnace and flame strong and weak in current large-scale thermal power machine group, in order to and
When, reliably detect the combustion case of burner hearth, prevent from that furnace puff accident occurs under the Ministry of worker of rough burning at low load, electricity
Boiler of standing must be equipped with perfect Furnace Safeguard Supervisory System.Flame detector is the headend equipment of Furnace Safeguard Supervisory System,
It provide signal accurately whether, conclusive effect is played to the normal operation of Furnace Safeguard Supervisory System.Flame detector
Including optical fiber, fire inspection protection sleeve pipe and cooling wind devices.Fiery detecting/monitoring principle is：Optical fiber examines protection sleeve pipe to boiler by fire
Flame in stove is monitored, and carries out cooling protection to flame detecting probe by cooling wind.Due to the fire inspection protection of the prior art
Casing is metal hose, and metal hose easily wears in use, damages and is detached from, and causes cooling wind short-circuit, cooling wind without
Method reaches and cools down fire inspection fibre-optical probe, can not monitor furnace flame to cause fibre-optical probe high temperature to damage, need stopping
Only boiler can just be repaired when the big light maintenance of unit the fire inspection protection sleeve pipe of damage, affects the safe and stable operation of unit.
Invention content
The purpose of this utility model is to improve existing station boiler flame detector, and cooling wind energy is made smoothly to reach and cold
But fire inspection fibre-optical probe, it is ensured that station boiler safe operation.
Technical solution is used by realizing the utility model aim：It includes optical fiber, fire inspection protection sleeve pipe and cooling
Wind devices, cooling wind devices are made of cold air duct and cool-air hose, and fire inspection protection sleeve pipe one end is connected on cool-air hose, and one
End is penetrated through furnace wall installing pipe in burner hearth, and in fire inspection protection sleeve pipe, key is to be equipped in fire inspection protection sleeve pipe for optical fiber setting
A piece fine steel tube, fine steel tube one end are connected on the air inlet of cool-air hose, and optical fiber is arranged in fine steel tube.
The effect of the utility model is：Improved station boiler flame detector, it is original using fine steel tube is penetrated
In fire inspection protection sleeve pipe, cooling wind pipeline to be connected, optical fiber penetrates in fine steel tube, to ensure that fibre-optical probe is not burned,
Maintenance cycle is extended, maintenance cost and maintenance time are saved, ensure that the safe and stable operation of unit.
Description of the drawings
Attached drawing 1 is the use state diagram of the use of the new type.
Specific implementation mode
As shown in Fig. 1, the utility model includes optical fiber 5, fire inspection protection sleeve pipe 4, fine steel tube 6 and cools down wind devices,
Cooling wind devices are made of cold air duct 2 and cool-air hose 1, and in fire inspection protection sleeve pipe 4, fine steel tube 6 connects the setting of fine steel tube 6
On the air inlet of cool-air hose 1, fire inspection protection sleeve pipe 4 is connected to outside 1 air inlet of cool-air hose, and optical fiber is arranged in fine steel tube
In 6, fire inspection protection sleeve pipe 4 is penetrated through furnace wall installing pipe 3 in burner hearth 7.In use, cooling wind is directly entered from cool-air hose 1
In fine steel tube 6 in fire inspection protection sleeve pipe 4, even if the fire inspection abrasion cracking of protection sleeve pipe 4, cooling wind will not be run out of, protect outward
The optical fiber safety work in fine steel tube 6 is demonstrate,proved.
