The quality of an incinerator is dependent on some key factors such as the reliability of the input materials and the overall workmanship of the equipment.

The reliability of a component is based on its failure rate and the reliability of a system as a whole, consisting of, say three elements, will be R = R1 x R2 x R3.

The reliability of such a series will be R1 = 0.9, R2 = 0.8 and R3 = 0.5 is R = 0.9 x 0.8 x 0.5 = 0.36, which is less than the reliability of the least performing component (R3 = 0.5). This reminds one of the well-known saying “A chain is as strong as its weakest link”.

The weakest link has to be identified and strengthened. It is also important to ensure those components which have a poor reliability in general have to be looked at and improved.

For this reason, a system or a component should be designed in such a way that it has an inbuilt “Life Prolonging Factor” which means that the product will not fail unexpectedly or before its life time.

The reliability of an incinerator will also depend upon its continuous usage, steps taken for preventive and predictive maintenance and how much downtime it is going to suffer from.

From the view point of the user of the incinerator, there are other practical methods to measure reliability and these include

1) How satisfying is the performance of the whole incinerator.

2) How does the design of the incinerator help in its ‘maintainability’

3) How many unplanned breakages has the incinerator suffered

We have many Life Prolonging Factors incorporated in our incinerator systems and some of these are

1. Customising the refractory (which is the backbone of the system) to provide high strength at high temperature, unlike conventional ones. This means there is no re-lining of the system every now and then.

2. Surface preparation of the chambers to provide long paint life.

3. Usage of time-tested components such as burners, instruments, fans etc. whose failure rate is very low.

We also measure the reliability of our incinerators in terms of the number of times a user has placed repeat orders. When we analyse the data, we find there are quite a few customers who, having used the incinerator satisfactorily for many years, have reposed trust in Haat and bought it again. Such users include oil & gas sites, healthcare, precious metal recovery, poultry, shipyards, paint manufacturers, etc.

In the 25 years of our service, these are many in number, which is a testament to the reliability of a Haat Incinerator.
