Haat has a few models of Hazardous Waste Incinerators that can meet emission standards of any regulatory authority in the world. These models have evolved over a period of time. Our own Common Hazardous Waste Incinerator Facility has helped us considerably in ironing out the little niggles here and there.

The models in the present range are:

1. LRD: This is a top-of-the-line product with many special features. It is of modular construction, enabling addition of more modules depending on the waste quantity and residence time requirements. It is lined with a very superior refractory material which exhibits high strength at high temperature, thus giving enhanced performance and life to the incinerator. The entry of the flue gas to the secondary chamber along with secondary fuel entry as well as atmospheric air through a temperature activated louvre system is a unique feature. The points of entry are at 120 degrees to each other which enables great turbulence and hence far better combustion of the products of combustion.

An attemporator system is provided in the primary chamber to contain temperatures in excess of 1000°C (depending on the waste) to protect the refractory and chamber from damage.

The PCC or SCC can be provided with a liquid waste feeding system, should it be desired.

The LRD incinerator is invariably provided with a ram loader for semi-automatic loading of the waste.

The LRD incinerator can be retrofitted with a venturi scrubber or a semi-dry one with gas cooler and bag filter and desired emission results can be obtained.  It is also provided with an ID fan and a tall stack , of course, come with the scrubber.

Many LRDs have been supplied by us within the country and abroad. The client profile includes Automobile Manufacture, Steel Plants, Insecticide Manufacture, Shipyards, Earthmoving Equipment Manufacture, Oil & Gas Drilling, Healthcare, etc.

2. PDR:  This incinerator is also of a modular design but a slightly simpler version as compared to the LRD. The refractory used is the same. A ram loader is provided, but there is no louvre or attemporator.

The PDR incinerator is an economical version of the LRD without the additional frills.  It can be retrofitted with scrubbers of any kind.

3. SWR: Haat`s Marine Incinerator model SWR is exclusively designed for disposing of ship`s waste oil and general garbage. It is also used in on-shore installations such as diesel-powered power stations and shore facilities in ports for disposal of ship`s wastes.

It is of a jacketed design to ensure safe skin temperature.

The SWR incinerator is ingeniously designed and constructed. It is of a triple chamber design with an ID fan mounted on top. The function of the fan is many-fold. It provides combustion air, cooling air for the jacket and air for the ejector.

The incinerator system is skid-mounted with waste oil tank as well as diesel tank for the burner. Burners are provided both for combustion and for the secondary and tertiary chambers.

The waste oil tank is constantly heated and agitated to prevent heavier particles settling down. It also has an on-line filter to remove sediments. There is a variable speed sludge dosing with in-built protection to prevent damage.

Solid waste is fed through the main charging door with its own safety features.

The system is always in negative pressure so that no leakage of smoke occurs.

The effective ejector mechanism ensures not only the negative pressure but also helps to bring down the flue gas outlet temperature to around 200 to 300°C.

Any type of scrubber can be retrofitted to the SWR incinerator, if desired.

The SWR incinerator is designed keeping in mind the ship`s limited and confined space and its design also takes into account the ship`s rolling and pitching.

The entire system is fully automatic with its own PLC and HMI.

The SWR incinerator is working in a power station in an Indian ocean island for the past 4 years and is being installed in a shore disposal facility in Vanuatu.
