Can we establish moving grate and rotary kiln together in one piece of land of area 9000m2?
If yes can you upload plant layout of combined version.

How can we save our land fill from so much non recyclable plastic. I am speaking of our every day house hold waste such as the plastic wraping that so many product come in. Also the every day use of \ zip lock bags\ and plastic film. hen I seoerate my garbage where now I am able to put all food stuff in the \ green waste container\ anong with all paper products. I seperate all that is possible I am left with PLASTIC. One does not realize this unless they take the time to do just that. It all becomes land fill. Go shopping and just take stock of all the items that are wraped in plastic. you will be amased. There must be a way to help with our environment and reuse all of this.

Do you have a US dollars cost per ton for a plant just for an aproximate

I am so interested in your process. I have been exploring your web page and I have found an interesting information about the incineration process.
I have reviewed the Lay-Out that you publish in pdf, but in the Example 1: Rotary kiln incinerator, dry + wet scrubbing, I do not understand what is the green line. Could you give a pdf copy more legible of this lay-out, please?
Thank you for your attention and your answer.

What is the process to reduce SO2 emission level from a waste gas incinerator to some around 800 ppm. The input to incinerator will be acid gases (emission gas from a gas refining plant)containing about 77,000 ppm of H2S (40%) , 47% CO2, & 10 % H2O. Acid gas flow rate is 17,000 kg/hr.

We have a rotary kiln cocurrent incinerator(1 tonne per hour) feeding organic waste, petroleum hydrocarbon sludge, activated carbon, aqueous waste designed by RLC technologies, usa. We are facing severe slag and slag ring formation in the incinerator inner surface. The slag is removed by chiselling and affects the refractory life.Could you suggest any remedies for the same.

- A waste field can affect ground water and drinking water, waste can make epidemies... We need to protect the people's health.
- Waste contains energy, we should not "waste" and dump energy. So a good incineration factory is near a good production facility which can use the energy.

Hello!
The waste truck goes 2x on the balance. Before and after depositing waste on the plant. The difference in weight is the waste left in de bunker. The sum of all the trucks is the amount which goes in the bunker
The overheadcrane also weights the waste which goes to the incinerator. The difference between the waste left by the trucks and the waste put in to the incinerator is the amount which is in the bunker. |

I don\ t have an idea on the cost implication of purchasing 1 unit of your incinerators, but I hope it is affordable. Kindly send a brochure and invoice to hyssopenviro@gmail.com. Thanks. Johnson Ebokpo Jnr

What is the electrical requirement (power & site lighting)and mechanical (natural gas supply)requirement for the plant?

The lighting is not relevant. Main ID fan and other smaller engines are necessary to make the installation well turning. The power depends on the capacity of the plant.
Gas is necessary only to start up the incinerator.
For example: for a 3000 kg/h incinerator, you need about 630 KVA connection. (of course you can have for ex. 1,5 kWe energy recuperation). |

I am working on a presentation to discuss disposing of disposable materials for the Pharmaceuticals industry and I want to learn about the potential benefits of incineration versus recycling. One question I was trying to answer was how much plastic waste is needed to justify installation of a factory based incineration plant?? Any ideas?
Please contact me at wflaherty@fhicci.com
Thanks,
Wayne

Waste incineration is the "last possible recycling" which is possible. So, it is called the "valorisation" of the non-recycble waste into usefull energy. Incineration technology should not make competion with recyling systems, because if it is possible to recycle the waste, it must be recycled (and it should be sheaper to recycle it). This is the environmental waste policy.
Medical waste has the disadvantage that it may contain a dangerous virus and it is a risk for the public health. This is why the destruction by incineration is the 100% safe way to evacuate the waste (and the viruses).
A hazardous waste incinerator, for medical and hazardous waste, also for plastic waste is profitable from +/- 300 kg/h. A general business plan, you may see here...
So, for plastic...
| Plastic recycling installion |
Incinerator |
| Investment cost: installation + building + land |
Investment cost: installation + building + land |
Running costs: electricity, diesel, workers ...
No or no complex flue gas treatement |
Running costs: electricity, diesel, workers ,...
Special extra cost: flue gas treatement |
| Costs of the residues is lower then the waste field (?), because this waste goes to the incinerator to reduse the mass amount and recuperate the energy. |
Costs for residues of the incinerator |
Profits:
Gate fee ($ / kg)
Selling recycled materal ($ / kg) |
Profits:
Gate fee ($/kg)
Energy recuperation ($/kWh) |
So, to make an incinerator environmentall acceptable, there must be an energy recovery system and the emission regulations must guarantee safety and peoples health (for ex: dioxines and furans emission < 0,1 ng/Nm3). This is why waste to incinerate (=non-recycle waste) will be expensive waste.
If the emission regulations are not important, or if waste field dumping is sheap. In this case, of course the question can be if it is not cheaper to just "burn" or "dump" the waste. This depends on local regulations and waste policy.
Waste fields can have after 20 years problems, for example polution in ground and drinking water. This is why the amount of waste fields should be minimalized and controlled. (Cleaning up a waste field may cost billions, much more than a good working incinerator).
I hope I helped you further, don't hesitate to ask more info. Thanks. |

Thanks for visiting our website.
My answer to your question is as follows : the dimensions of the kiln are individually calculated in relation to the
physical and chemical properties of the waste (amounts to be treated,CV,density,speed of combustion,ash content,required burn out,etc.).As such they cannot be standardised,but are engineered case by case.
The dimensions of the post combustion system are related to the volume of the kiln (primary combustion chamber).In general they are about 120% of the volume of the primary chamber,for maintaining the required residence time (min 2 sec) at 1100 or 1200 Degr.C .
Please give all the above required info and we will give an estimated dimensioning.Thanks. |

What are the NOx emissions of your rotary kiln incineration plant? Why you have no deNOx like SNCR? The post combustion at 1100 degr.C creates a lot of NOx.

NOx emissions do not form in significant amounts until flame temperatures reach 2800 F (1537 degr.C). The flame of a burner (start-up and support burners) generate this temperature.
More info on: http://www.alentecinc.com/papers/NOx/Th...
The burner of co-current rotary kilns has to continuously maintain the temperature of the combustion and post combustion chamber, this is not the case for counter current rotary kilns. So, counter current rotary kilns have no NOx problems, the EU-limit is 200 mg/Nm3 and 160 mg/Nm3 is a normal average - hourly value. ( http://www.bicgroup.com.sg/different_types_of_rotary_kiln.php ).

Thanks for visiting our website and for your interest in our products.
At present,we have only one size of ammunition destruction plant.However,we are willing to design a smaller version,but please be aware that the volume and the specificationsof the combustion chamber must be adapted to the caliber and the power of the ammunition to be destroyed.So,please give specifications of the ammunition and the quantities to be treated.Thanks. |
