An incinerator is a thermal equipment working at very high temperature and needs to function efficiently and to be endowed with a long life.

Towards this end, as a manufacturer, we do certain things without any compromise.

Among the many quality checks that we carry out during the manufacture of an incinerator, the following steps are mandatory;

1. Matching actual fabrication to drawings

2. Using only the right MOC for production; no deviation whatsoever

3. No material issued to Production until cleared by Quality

4. Quality to function as a watch dog during the entire process of manufacture and testing

5. Hold points strictly enforced by Quality and followed by Production

The two most important parts of the manufacturing and testing processes include

A. refractory curing

B. test run of the manufactured incinerator

The reader might be aware that we use mostly castable refractory as opposed to bricks. The main reason for this is that while bricks have a limited strength (CCS) the customised refractory we use develops a higher strength at high temperatures, something in the region of 700+ kg/cm² at 1000°C.  To attain this strength and to make it suitable for transportation in difficult terrains, we do refractory curing over a period of 5 days.  This is a critical activity requiring continuous heating of the refractory (24 hours x 5 days), raising the temperature every day until the desired maximum temperature is achieved and then cooling it slowly.  Any stresses that developed internally during the lining work is relieved in the process.

Apart from the above, we carry out a trial run or performance test of the finished incinerator. This is another critical pre-inspection/despatch activity.  The trial run is between 4 to 24 hours depending on the nature of the incinerator and its design and the standard laid down for FAT (Factory Acceptance Test).  This, in other words, is our own internal validation.

The test run is absolutely essential because this identifies and eliminates any glitches that the system might encounter at the customer’s end.  It could be a minor leak in the pipeline or failure of an instrument or electrical fault or programming of PLC or refractory related issue or temperature within the chamber and outside and so on.

When the test run is completed, everyone involved, be it Projects, Production, Quality or Service is happy that the system will not face any problem at the site because whatever problem if any, has been resolved during the test run. This also means the commissioning or SAT will go through without any issues.

In these pandemic days of virtual commissioning, when we supply the incinerator equipment the customer may rest assured that this will work without any glitches and will provide a good performance and long life.
