Incinerator Monitoring case study

A manufacturing plant needed to monitor the top of their incinerator for flash fires and also the degradation of the burner tip via a site glass.

In the North West of England, a manufacturing plant utilised an incinerator on site for the destruction of residual waste organic products. The Oxidiser was located in a remote part of the plant approximately one quarter of a mile from the main plant control room.

The building housing the incinerator was a multistory structure incarcerating the vertical construction across a number of floor levels with the waste product feed entering from the top. The iCAM100 CCTV camera provided an easy to install and very cost effective solution for visual monitoring of the process area.

A viewing glass located approximately one third of the way down from the top provided an observation point to examine the status of the incinerator igniter tip which deteriorated after a period of time and eventually disintegrated into the fiery inferno.

Two problem areas were identified with respect to the incinerators operation the first was that the incoming waste feed occasionally spilled some of the product out through flanged joints which then ignited on the hot exterior surface of the incinerator creating the possibility of localised fires.

 

Incinerator MonitoringThe second problem was that whilst the igniter tip was utilised prior to the reaction becoming exothermic eventually would fall fowl of the incineration process itself and disintegrate dropping off into the molten mass.

The need to monitor the status of the incinerator was crucial but the solution was extremely labour intensive and utilised an engineer that would on a regular basis inspect the incinerator.

This inspection procedure did not resolve the problems as a fire could break out the moment the engineer departed, hence a better and more cost effective solution had to be found.

The area was risk assessed and classified as a hazardous area hence any equipment that was to be employed would have to be suitably certified.  The solution proposed by Extronics was the installation of two iCAM100 cameras. One camera was positioned looking out across the area of greatest risk of waste spillage that could result in a fire. The second camera was mounted behind a tinted glass plate at the end of a viewing site glass and was focused directly onto the burner tip.

The two cameras were then connected back to a monitor in the control room with split screen view and recording capability to provide historic information.

Weighing only 650 grams and with an overall length of 130 mm the iCAM100 is a compact lightweight but delivers value for money by comparison to some of its much larger and extremely heavy contemporaries which carry a price tag to match their size.As with any product it is the nature of the application that determines its suitability and this overview of a tried and proven work horse in the area of visual technology provides and insight into how the iCAM can prove to be an invaluable investment.
