|OUR TRANSPORTABLE SOLUTION |
The TIU-8G+ 2017 solution can be put anywhere into operation and has an excellent combustion capacity. Capacity up to 250 kg/hr with a very big volume of the incineration chambers.
The whole plant is mounted on two 40 feet flat racks and consists of four segments:
- 2 stage incineration module with cooling module
- Filter module with supply module
The plant concept based on durability to reduce maintenance efforts under site conditions which can be difficult for the operators at site. The two modules combine a fully equiped and environmentally friendly stand-alone unit!
It has all necessary auxiliaries on board, like diesel pump and a compressor system. The incinerator can be delivered optionally with a lance spray system for liquids, a power generator and a continuous exhaust gas monitoring system (CEGM).
It is equiped with a two-stage filling system consisting of a concrete gate valve with feeding hopper for top loading. The refractory lining is based among others on extremely heat-resistant fiber and a wear-resistant fire concrete. The easy installation and operability improve the transportable usage under field conditions.

ENVIRONMENTAL FRIENDLY COOLING UNIT
A heat exchanger is a modular part of the whole incineration system. It will cool the flue gas down to a temperature of averagely 230 °C. The advantage is that this facility do not require water consumption. In contrast to a spray cooling system this facility saves approx. 1-4 tons of water per hour.
- Air cooler.
- Pipes made of carbon and stainless steel.
- Cooling air fan and blow-off pipe for cooling air.
- No water consumption.
- External insulation.
THE INCINERATION PROCESS
The basic modules are made for the THERMAL DESTRUCTION that combines high temperature, long residence time and high turbulence together with an adequate fuel management system to ensure that hazardous materials are efficiently destroyed. Hazardous materials, when heated to a very high temperature undergoes predictable physical and chemical changes. The high temperature, that is over 1000°C prevents the formation of complex organic molecules and breaks down organics into gas. These primary molecules are stable at that temperature. The oven of our system is capable of burning the waste at a standard temperature of 850 - 1100°C. The more toxic the material, the higher the burning temperature needs to be. An incineration unit will be extended with two additional modules: a) an air cooling system on the same flat rack and b) a filter system for dust filtering and chemical neutralization due to an adsorption system, that combine the following advantages:
CHEMICAL NEUTRALIZATION has been done by use of a special additive that must be added to the waste. This is a very effective additive for SO2, HCl and HF, heavy metals, dioxins, etc.
PHYSICAL FILTERING will be applied by means of a special filter system. The particle removal creates a filter cake, which supports the removal efficiency. Depending on the differential pressure measured across the filter, the parts of the filter elements are cleaned by means of pressurized air impulses.
ADSORPTION is a part of the chemical neutralization, e.g. the binding of molecules or particles to a surface will be done by means of feeding the flue gas through an activated carbon mixture (additives NaHCO3). In this stage the flue gas components with color or those that have taste or odor will be bound, so all these may-be-non-toxic- but disturbing gas components will be eliminated and a colorless, odorless flue gas will be emitted to the atmosphere.
As a result above destruction/separation systems in combination care for a very environmental friendly incineration.
|TWO-STAGE TOP FILLING SYSTEM |
This system consist of a state of the art double gate semi-automatic door that do not allow leakage from inside of the fire room to the outside. This door system is consisting of two gates: upper gate is a flap system opened and closed pneumatically. The lower gate is a horizontally sliding gate that is also actuated pneumatically. This gate moves into a closed room. If the feeding is done, the waste falling on to the lower gate. If the upper flap closes the lower gate will be slided horizontally and the waste fall down to the fire room. The lower gate is cladded with fire resistant special concrete like inside the main combustion chamber. The feeding is controlled by the operator.

|INCINERATION PROCESS AND BURNER CONTROL |
| || |
An automated burner serves for the heating of the combustion chamber subject to the temperature of the fire room. For heating the unit at start up the burner is in operation. The feed opening should remain closed, as long as the necessary flue gas temperature is not reached. In the post combustion chamber the gas is heated up to a minimum of 1100 °C. The incineration process produces a sterile ash quality.
The incineration process produces a sterile ash quality. If the incinerator is used as a stand alone unit, the stack module will be mounted to it and the flue gas will be released mixed with fresh air for cooling down the hot flue gas before discharging to the atmosphere from the stack.
|INSULATION / LINING |
|The main combustion chamber is lined with a special ceramic fiber, which is surrounded by a concrete sheath. It is specially blended and very wear- and impact-resistant. The bottom of the post combustion chamber (gas combustion) is lined with a special ceramic fiber, which is surrounded by a concrete sheath. The walls are insulated with a special ceramic fibre, which is heat-resistant up to 1200 °C. This fiber has a special coating as sealing surface that makes it insensitive to dust so that a wear protection is given. Maintenance and repair work are easy to perform. |
|THE SECOND MODULE |
|ADDITIVE DOSING SYSTEM |
|On top of the cooling system near to the discharge side there is the special opening to feed an additive. Via this opening an additive can be loaded manually, if needed. The additive dosing system can be supplied in two types: |
- Standard version for manual filling or
- optionally as an automated filling system.
The additive (NaHCO3) is needed if chemical substances like PVC, plastics, etc. shall be incinerated because that can cause emissions of dioxins and furans or heavy metals. The activated carbon added to the additive ensures that the flue gas will not have any color and odour.
|TEMPERATURE RESISTANT FILTER UNIT |
|Picture: Sample of a container sized (OT) filter module |
|This filter system is a modular part of the whole incineration system. It is connected to the outlet of the air-cooling unit and filter the flue gas of the incineration process. |
- Filter with fabric or ceramic filter candles.
- Temperature resistance.
- Dust discharge with a screw conveyor system.
- Induced draft fan.
- External insulation.
The filter system ensures cleaning of the flue gas from fly ash and all emissions, color and odor by means of the additive that is added from top of the cooling module above.
