Now I am going to give a information about the technology which is a point of interest for some big industries. Flame scanners is a device which accurately detect the presence or absence of flame in a combustion chamber with the help of advanced sensors and algorithms that can discriminate it's target burner from adjacent flames in the same combustion chamber. These scanners can be used with all fuel types and burner configurations.
Can you imagine that these high quality sensors are made to detect the ultraviolet lite emit by flames and measures the exact amplitude and frequency of a flame.Think about it,how much useful these device are,not only for a boiler industries but also in a place were there is a chance of catching fire. Ex Malls,stores,buildings.

These scanners can also detect ultraviolet emissions from fossil fuel flames such as natural gas, coke oven gas, propane, methane, butane, kerosene, light petroleum distillates and diesel fuels.
The basic properties of a flame scanners are
1 Fully integrated design - a true one piece system.
2 No programming - minimal setting up - 'out of the box' operation.
3 Superb detection, sensitivity and wide angle of view.
4 Field proven and reliable technology.
5 Worldwide safety agency approvals.

INDIA'S SCENARIO
Currently in India only few companies are there which are serving our nation with this crucial technology. Among these a biggest name is Lucent Marcon's Pvt. Limited which provide a products and solution for Industries.
