This presentation covers
1. Different Waste Density and their effects
on incinerator capacity
2. Batch vs continuous machines
3. Different refractory styles and how they
effect the destruction of waste
4. Getting automatic loaders right.

3. Waste Density Design

Municipal Waste Density Design
Residential waste:
85-175kg per 1m3
Addfield are worldwide industry leaders in the design and manufacturing of animal, medical, aquaculture, mobile
and bespoke incinerators.
“We don’t sell products, we sell solutions fit for purpose”
What does this mean?
For every 1m3 cube space
You can fit on average:
130kg of residential waste
1 metre
1metre
Waste density design and its effect on daily throughput
4. Batch Machines
www.addfield.com 4
About:
• Batch loading
• Load once per day
• Limited throughput
• No waste movement inside
• No continuous de-ashing
• Not 24 hours operation
• Limited uses.
• 6-8 hour cool down period
between cycles
All most all batch loading machines are adaptations of animal incinerators. Animal waste has a higher
Waste density design of around 500kg/m3. As actual such load capacity numbers are inaccurate for municipal waste
Batch Incinerators Inside a Batch Incinerator
Questions & doing the maths:
How much waste can fit inside a batch
loading machine with a large 4m3
volume?
Maximum daily throughput:
130kg x 2m3 = 260kg (0.26Tonnes) of
Residential waste
Why can’t I load hot?
• Smoke and odour will be emitted
from the open door of the machine
• Risk of injury/death for the
operator.
• Thermal shock will damage to the
machine shortening its life
Conclusion: Batch Loading Incinerators make little financial and
practical sense due to there limited daily throughput .
5. Batch Machines With Automatic Loaders
www.addfield.com 4
Batch loading systems, adapted again..
1. Waste has nowhere to go, eventually leading to blocking of flue. Dangerously pressurizing
the machine
2. Non-combustible will remain static, insulating unburnt waste underneath
3. Pressure exerted on to lid and door seals. Waste and ash has no where to go, leading to
excessive smoke and waste leakage.
4. Hot de-ashing will lead to excessive smoke leakage
5. Cool down required between cycles to de-ash. De-ashing doors not sufficient size
6. Not 24hr operation
7. Incineration encourages a large cold spot on the base of the machine as the waste is static.
8. Limit size heavily restricts limits throughput.
9. Lack of waste movement inside hinders burn rate.
10. No waste metering, to let the operator know how much waste is in the system. Limiting the
through-put or causing failure from blockage
11. Unable to offer complete combustion
12. Originally built for animal waste, which have lower mass emissions, resulting in an
undersized pollution control system
Conclusion: Visually a better looking option however fails to deliver on various points.

About:
• Built specifically for municipal waste applications
• Stepped Heath Incineration Principle
• For waste with a density of 130kg/m3
• Double staged door loading prevents emission leakage
• Continuous automatic loading
• Integrated ash dropout zone and..
• Continuous automatic de-ashing
• 24 hour operation
• Housed within its own building
• Integrated bin tipper and hydraulic ram
• No cold spot, multi hearth ram sweepers
• Waste automatically metered and weighed
prior to entry to confirm burn rates and for logging
