Daily Fill-Space:

Daily Fill Space Required Based On 90 Tonne/Day Facility

graph

Based on 90 Tons Per Day (TPD) the amount of landfill space required under existing methods, indicated on the left, is 350 cubic meters. You will see (in the next column to the right) the adjusted requirement if a disciplined ‘Recycle program’ is in effect. The next column (red) shows the disintegrated residue from the same 90 tons, which requires just 25 cubic meters while the last column (yellow) indicates the ultimate in reduction, with recycling in effect, at 15 cubic meters of landfill space.

 

Operating Temperatures:

Daily Fill Space Required Based On 90 Tonne/Day Facility

The primary and secondary columns in this chart show the difference in operating temperatures between current incinerators and the KDS system. The noticeable lower temperatures of incineration are a product of the use of “grates”. Molten glass and aluminum cans may clog these grate systems, and due to the higher heat value of modern garbage, the grates are subject to bending and distortion. No such threat keeps the Disintegrator from retrieving the HHV (High Heat value = 7446 Btu’s/Lb) of the trash presented. Conventional incinerators, with all their restrictions, commonly recover only the LHV (Lower Heat Value) of around 4500 Btu’s/Lb.

The centre column is the optimum operating range for the Disintegrator where we still have perfect combustion. We also have a reserve capacity when an Energy Recovery Component (co-generation turbine) is included in any KDS installation.

 

Afterburner Dwell Time:

Two of the more important factors in dispatching the impurities resulting from the products of combustion, are Dwell Time and Temperature. Here you see a comparison between the Disintegrator on the left at 4.2 seconds while the conventional design delivers an inadequate 1 second. Designed with the destructive criteria for every known carcinogenic matter (excluding Radio-Active) the Disintegrator is capable of accepting and processing the widest range of waste types and classes, rendering them inert.

 

Waste Reduction:

The net volume and weight reduction in the process is 83.6% and 64% respectively. A dramatic saving and reduced reliance on landfill space requirements.

 

KDS Ash Discard:

KDS-Ash-Discard

What can we say? The ash discard speaks it for itself. Where the regulations call for 10,000 ppm of organic and/or inorganic carbon in the ash, the discard from our Disintegrator has less than 1 ppm! The nodule like mass is bottom ash. The vial contains coarse particulate from our cyclonic separator. It removes same from the gas stream prior to entering either a boiler and or heat exchangers. Altogether a very manageable and dry material.

 

AGRA Chart:


Here we have the actual printout from AGRA’s recording computer. The two medium spikes are the result of propane canisters exploding; these bottles were identified in the feed stream. The tallest spikes are when the recording machines were changed during the test period. 

The AGRA (now known as AMEC) chart shows the THC content of our emissions. Where 300 ppm of unburned fuel is permitted in the off-gas, the Disintegrator’s inherent “Total combustion” delivers just 35 ppm while often operating at Zero THC’s! An astounding low of 0.00 ppm, can be seen in the picture, below right.

 

Stack Emissions:

The stack and Dial are self-explanatory and warrant serious consideration when comparing our system to other methodologies. The most evident sign of success is the visual inspection of the stack emissions. As you can see, we have a crystal clear emission level. During the four-day test, not one inquiry was made in respect to sound , smell or smoke, despite the machines proximity to the Main Street and fast-food outlets. 

The KDS goes way beyond their suggested 100 ppm hydrocarbons achieving 0.00 ppm!

 

You compare the difference:

The photo of raw “Run of the Dump” garbage was originally seven tons of trash, converted to 1-1/2 wheelbarrows of clean and organic free ash. It easily meets the TCLP requirements (Toxicity Character of Leachable Products) and is comfortably suitable as land-fill in registered locations.

  • Run of the dump, as delivered.
  • No sorting or screening of the curbside waste other than any pre-delivery recycling programs in place.
  • Despite the recycling efforts the mass still contained an abundance of glass, metals and paper.
  • High operating temperatures, excellent mixing and appropriate dwell time reduces the waste by 83% volume and 64% weight.
  • Where the Guidelines call for carbon content of 10,000 ppm maximum, the KDS discard contains a mere 0.04 ppm.
  • Simply put, a tandem garage truckload of garbage is reduced to a few wheelbarrow loads of harmless ash.
 

Conventional Incinerator Ash:


The inadequate processing of the same type of garbage in a multi million dollar incinerator of conventional design leaves much to be desired. This includes the quench tanks, another very costly system requirement. The total combustion attributes of the KDS units negate the need for such added costs.

 

Quality Of Combustion:


We’re very pleased to demonstrate the quality of our total combustion. This recognizable object (ceramic mug) is thoroughly embedded into semi-molten glass and other debris, which exited the Disintegrator.

 

Typical Quench Tank:


The unsavory scum topped surface of a conventional and mandatory Quench tank for the still burning debris, which is discharged from all incinerators. No such system is required in the Disintegration process, supporting its super cost effective qualities.
 

No Quench tank required:


The quality and dryness of our Ash Discard is considerably more manageable in terms of quantity and toxicity.

 

Disposal Facility Of The Future:

This image is a subtle reminder of a typical everyday landfill site. Just burying the problem won’t make it go away!

This image is indicative as to what your Disposal Facility (Landfill) of the future could and should look like.

 

Typical Footprint of The New Facility:


A typical footprint of the system is depicted in the previous picture. The weigh-in scale, should the facility be on multi-user pay basis, keeps an accurate record to whom the billing should go! Additionally, the truck management system-computer operating the scale, communicates with the Programmable Logic Controllers (PLC’s) operating the Disintegrators. This insures that a continuous and steady consumption of the waste and that the system would not run out of, or have too much MSW on the floor when the newly delivered feedstock arrives the next morning. This feature also eliminates the stockpiling of waste. No material should be on the reception hall floor any more than 26 hrs. This is an important factor when one considers the “auto-thermic ” (no supplementary fuel required) nature of the Kearns Disintegration System.
