THE VERSATILE LRD MODEL INCINERATOR

The LRD model incinerator is of a unique design which provides it great versatility enabling it to handle many different types of wastes. When combined with appropriate air pollution control equipment, it will easily meet Euro emission standards.

Firstly it is of modular construction. The primary chamber capacity can be increased as required. The secondary chamber is also modular which means residence time of flue gas can be increased as per local standards.

The primary chamber has a solid hearth which can take heavy loads. It is also provided with a large ash door at one end and this can be used as a loading door if there is any problem loading the waste through the ram loader. The secondary chamber has an unmatched design for creating great turbulence and hence very good emissions. It is placed tangentially to the primary chamber, which causes change in direction of the flow of flue gas. At the point of entry of the flue gas, there is a specially designed arrangement with orifices through which the flue gas enters from one side, followed by the secondary burner flame coming from a 90 degree angle. There is also an optional temperature controlled louvre system which opens and closes partially or fully depending on chamber conditions and ensures adequate natural air supply and this is located opposite the burner.

The flue gas, burner flame and compensating natural air from the louvre all create such an excellent mix of gas, flame and air along with turbulence, there is no escape for the products of combustion but to get completely burnt, leaving a clean gas, free of particulates.

The hydraulically operated ram loader which is a compulsory part of the system is custom designed for the waste type and quantity and eliminates the risk of fire hazard to the operator while loading waste. It also limits the amount of manual labour required.

The refractory used in the LRD is a time tested castable which is quite unique to Haat’s incinerators. The custom designed refractory does not lose its compressive strength when temperatures in the region of 1000°C are reached. On the other hand, the strength increases due to the special elements added which provide this characteristic. This is very vital considering the fact that refractory is the heart of an incinerator and it has to
