The FIREYE 85UVF1 fire detector is a high performance flame detector designed to monitor and control the flame state during combustion. The following is a detailed summary of its features and functions:

Technical basis:

Based on ultraviolet sensing technology, ultraviolet light in the flame can be detected to determine the presence, location and size of the flame.

High precision and stability with solid state flame detection sensor.

Performance characteristics:

Fast response: Can quickly sense the change of flame status.

High sensitivity: High sensitivity to small changes in the flame.

High reliability: It can work stably under various environmental conditions.

It has the function of automatically setting ON/OFF threshold value, which can be set and adjusted according to actual needs.

Scope of application:

Suitable for a wide range of combustion equipment such as pipeline burners, industrial gas burners, refinery applications, low NOx burners, exhaust gas units and incinerators.

It is particularly suitable for measuring light emission in steel plant applications, such as burners that burn blast furnace gas and coke oven gas.

Design features:

The Phoenix Flame scanner includes an internal flame relay that automatically sets ON/OFF thresholds without the need for a remote flame amplifier or flame switch.

The scanner detects the modulation amplitude (flame "flicker") occurring within the target flame at a wide frequency.

Automatically stores the amplitude of the target flame and the optimal on/off criteria, and automatically selects the appropriate sensor gain.

Fully automatic diagnostic and electronic self-test functions are included to ensure the reliability and safety of the equipment.

Prices and Availability:

Prices will vary depending on the supplier and quantity purchased. The market offers price options ranging from a few hundred dollars to tens of thousands of dollars.

The main suppliers include Wuhan Yuli Automation Technology Co., LTD., Chongqing Yugan Mingrui Automation Technology Co., LTD.

Application in power plant equipment:

It is mainly used to detect the existence and characteristics of the flame to ensure the safety and stability of the combustion process.

It is installed on the observation hole of the boiler or other combustion equipment to monitor the combustion in the furnace in real time.

By detecting the radiation intensity and spectral distribution of the ultraviolet or visible light of the flame, it can determine whether the combustion is normal, whether there is incomplete combustion or flameout.
