Industrial Incineration Systems

Applications:

The industrial incineration system is designed specifically for the disposal of all types of waste from Type 0 to Type 5, and is used extensively in:

• Industries for paint stripping from coated parts, paint sludge, liquid chemicals, solvents and resins.

• Factories for oil-soaked rags, grease, and spent oil.

• Effluent Treatment Plants for destruction of the sludge generated.

• Hospitals, Nursing Homes and Clinics for the disposal of contaminated dressings, carcasses, organs, solid organic wastes, etc.

• Biological and Pharmaceutical Research Labs for the disposal of tissue and plant culture, animal cadavers, wet gelatine, capsules, biomass, de-activated carbon and outdated drugs.

• Municipal Corporations for the disposal of civic waste such as garbage.

• Canteens for disposal of all vegetable and food waste.

Available in capacities from - 10 kg / hr to several tons per day.

Services Offered:

The general scope of supply includes a suitable incinerator, the design providing for the requisite dwell time, water quench for reducing the gas outlet temperature, wet venturi scrubber for trapping particulate matter, packed bed tower for gas scrubbing and mist eliminator, eductor system and 30 meter chimney.

Incinerator:

Design

The normal design of the incinerator is a 2-chamber machine with one primary chamber for loading the waste and an after-burn chamber for burning the products of combustion. An incinerator can also be designed with a pre-combustion chamber, where, for instance, parts coated with paint will be stripped of their paint and the paint sludge, which is the actual waste, will be loaded in the primary chamber for burning. The incinerator design takes into account in particular, and this is a very important when considering different industrial wastes, the long dwell time that will be required to fully burn off the gases, depending on their volume, concentration and toxicity. Our design envisages locating both the chambers within the same body of the machine to ensure control and economy providing for creating turbulence for the gases.

A large sized door is provided for easy loading of bulky items directly into the large combustion chamber. It is also possible to provide for a chute and / or a hopper to avoid opening the charging door when the incinerator is on or if the waste is in a liquid or semi-solid condition.

Primary combustion takes place at very high temperatures encouraging the reduction of combustible wastes to a fine ash and the double chamber retort design provides the long dwell time and turbulence needed to promote the effective after-burning of suspended particulates and gases.

The incinerator can be so designed as to permit disposal of liquid and slurry wastes in the same system with a special liquid disposal arrangement. The burning rate could be from 50 ltrs / hr to 250 ltrs / hr and more, if required.

Construction:

The incinerator is constructed of welded rectangular section frame, lined throughout with high-alumina, castable refractory having a high cold-crushing strength and reinforced with stainless steel needles, in modular block form. It is further heavily insulated on the cold face with high heat-resistant insulating material. This is generally recommended for batch type operation.

Where continuous operation is desired, refractory bricks of suitable thickness will be used with insulating castable for the cold face.

The hearth can be made of heavy duty cast fire bars or solid refractory in the primary chamber.

Water Quench:

In handling wastes of complex configurations, it is essential to scrub the particulates and gases so that the final emission from the chimney is well within the norms. As a first step, the flue gases from the incinerator have to be cooled from about 800°C, to say 80°C.

The water quench is made of suitable grade stainless steel  with a water spray. The gases are cooled in this equipment before entering the wet scrubber.

The size of the quench and pump and motor capacity would obviously depend on the volume and velocity of flue gas coming out of the incinerator.

Wet Venturi Scrubber:

Air scrubbers perform a critical function. They purify noxious gaseous emissions prior to release to the atmosphere. A scrubber's efficiency for sub-micron particles is often a critical consideration in the selection of a specific type of air scrubber. Sub-micron particles present a special concern because these particles will cause, at the very least, irritation of breathing passages and more importantly, may contain toxic compounds.

Venturi type scrubbers are ideal for removing sub-micron particles including:

• Separation of particles from humid or corrosive gases

• Fine dust that could be adhesive, combustible or explosive

• Combined gas and fine particle air streams

• Gas cooling

Standard and adjustable throat venturi scrubbers can be offered to suit the requirement of the industry.

The scrubber can be offered in steel, stainless steel (different grades), etc., to suit the application.

Mist Eliminator / Packed Bed Tower:

The scrubbed gases from the wet venturi scrubber pass on to either a mist eliminator or a combination of mist eliminator-cum-packed bed tower. The function of this system is to ensure that moisture or mist is not carried to the eductor fan and at the same time scrub the gases once again using a packed bed tower. Different mediums can be used.

The mist eliminator / packed bed tower can be offered in mild steel / SS constructions.

Automatic / Semi-automatic Loading and Conveying System:

The loading arrangement can be with the help of a trolley or pneumatic loader through a suitable chute / hopper. Conveyors may be with rubber or steel rollers using a belt or screw conveyor. This would depend on the waste application and site conditions. Bogie hearths may also be used where waste contains large ash content.

Flue Gas Recovery:

Several flue gas recovery systems can be offered, depending on the waste chemistry, its moisture content, quantum and continuous use of the incinerator during a day. These include steam generation, hot water generation and re-circulation of flue gas for preheating / removing moisture from the waste.
