Incinerator Introduction
Principle of the Incinerator equipment is incineration/combustion/burn. Generally, the function is waste treatment for Solid waste, Liquid waste, Gas waste, etc.
The main body is one combustion chamber (at least), Refractory line or firebrick, Insulation materials and the outer plate. Ignition element is external oil or gas burner. The burner can be running until waste burnout but for some waste like plastic, paper (sometime, mix coal with waste before feeding), they can combustion itself after Ignition. During combustion, burner has a fan itself for Oxygen supply and also protect burner avoid heat damage from combustion chamber. And, there a external fan blow air into combustion chamber. The Exhaust gas blow out after combustion.
Considering Environmental Protection requirements and rules, almost all incinerator have secondary combustion chamber (after-burn, post-combustion), even if third combustion chamber. The secondary burner burn the Exhaust gas from primary combustion chamber, this technology make sure sufficient combustion, few black smoke and smell.
The updated incinerator technology focus on Exhaust gas treatment to remove Hazardous material and other function from incinerator, like heat recovery (waste to energy), save fuel cost, PLC Automation operation.
In some Developed countries, some new waste treatment method like High-temperature cooking, waste carbonization, crushing sterilization technology is instead of incineration technology.

An open meeting for the community and anyone concerned was convened last Wednesday 1st October at Clann na Gael Community Hall. The meeting was well attended and was chaired by the Combined Residents Against Incineration (CRAI). The meeting was attended by local politicians and some representatives from Clontarf and Fairview.
Frances Corr, chairperson of CRAI outlined to the meeting the 17 years of concern and resistance to this project and reminded the meeting that on many occasions councillors have opposed and voted against this project. Despite this the latest Dublin City Council Chief Executive has signed the contracts with all the other Dublin Local Authorities to give Covanta the go ahead to start building. Covanta has stated in their recent release that they are ready to start building within weeks.
Many councillors wished to speak at the meeting. While being adamant about supporting resistance to the project, there were no specific solutions put forward by any councillors. Many locals advocated the need for civil resistance if necessary and many in the community are prepared to join with these type of actions.
CRAI are examining the specifics that were set down in the original planning conditions as there is a genuine concern that these may be breached, even at this early stage. The Poolbeg incinerator was originally planned on the basis of burning Dublin waste, yet given the size of the plant and the figures involved, it is highly likely it will need to take National waste to keep its need of 600,000 tonnes to accomplish it’s commercial goals and profits.
Although John Gormley was in attendance as a concerned resident, he was asked to speak to the meeting to give his views. Gormley outlined how the pursuit of “this incinerator was a stupid policy and would fossilize recycling efforts in Ireland.” With so much waste needed, it would twart national policy and motivation to recycle. Gormley emphasised that the project needed to be stopped “by getting into court as quickly as possible.”
A long time opposer to the project, Joe McCarthy, also spoke to the meeting and brought up many technical points regarding the incinerator. Joe McCarthy and Valerie Jennings are helping CRAI work out the technical points that may be contravening the conditions set out in the planning permissions for this plant and it is expected that there will be a legal challenge, such as a Judicial Review, initiated against this incinerator very soon.
In the meantime, there will be a growing resistance to the project on the ground. Northside groups were also in attendance. This included the Clontarf Residents Association as well as the Stop the Poolbeg Incinerator Campaign, a concerned group based in Marino and Fairview that have formulated since the announcement that this industrial practice will now take place in the heart of Dublin Bay. There seems to be much concern and alarm by many Dublin residents who may have been taken by surprise that this incinerator is being built when so many were of the view that it had been terminated some time ago.
CRAI announced a march to the Dail on Wednesday 22nd October starting at 5pm in Ringsend. “It’s our first march on the Dail and it’s happening there as we believe that is where the power lies,” says Frances Corr. The march will convene in Ringsend at the church and set off for the Dail. It is hoped that this march will draw in all those who have genuine concerns from Dublin and beyond. Anyone who cannot make the walk can join at the Dail by 6pm.

Solid Waste Incinerators
The Contractor shall provide a Cremation System package for TWO (02) Cremators and system approved by related authority, which must fit into the allocated area as shown on the plan drawings. The work shall include but not limited to design preparation, authority design approval, supply, fabricate, construct, commissioning, testing, operational approval, provide training and also warranty of the system package. The work shall include all preliminaries, related civil and structural work, mechanical and electrical work and all external work required for the proper completion and operational of the system and as follows :The incinerator will be used for a group of private multi profile hospitals.
The hourly-generated waste is about 100kg per hour, but with 1000kg daily amount.
Due to the economic situation in Bulgaria now, our researches shows that a 100kg/hour system can fit the needs set in the project.
Please, offer us an Incinerator system that can match the parameters described above. We are ready to give information that is more detailed if you need such one. Within the technical specifications of you product we need to have full details of the parameters of exhaust gases, with all certificates you have about the environmental safety regarding EU directives.
1. All preliminaries which shall include but not limited to providing work insurances, taxes, mobilisation and demobilisation, contract management and supervision, design and professional fee, authority design approval, operational approval, site preparation, temporary storage, health environmental safety and security, setting out, CIDB levy, duties, deposits, fees, charges, contribution but not excluding only the bank guarantee to the authority JPP which shall be provided by the Client, progress reporting and other required preliminaries for successful completion of the work.This type of incinerator is what you have described as a ‘low temperature thermal decomposition incinerator’. We can speed up the burning process by using hot air from a downstream process which can be fed back into the incinerator to raise the burning temperature.
considerably. These kinds of incinerators are the sort that would probably have been made and used many years ago before the anti pollution regulations were brought in. We believe that they would be very simple and cheap to manufacture for a company such as yours, as long as a large sales volume could be obtained. We believe that our technology will create a large need for this type of incinerator and would also make a good business opportunity for a company, such as Clover, who is able and willing to manufacture and supply them. I am sure that this simple type of incinerator could be easily modified to enable automatic charging and probably also automatic cleaning?
2. All structural, building and architectural work which includes but not limited to construction of all reinforced concrete work, chimney, structural steel work and all building work for all necessary requirements, operational and control panel system for proper completion and successful operation of the syste. The Contractor must make good all the works being disturbed.We want a very simple, single combustion chamber, incinerator which is capable of burning all types of waste and rubbish products. We will be treating the emissions from the incinerator in another process so we do not have to have scrubbing or other cleaning equipment to avoid pollution.
The incinerator is required to operate 24/7 continuously so it needs to be able to be cleaned whilst still operating. The waste materials being burned will contain non flammable materials and these will need to be cleared out of the incinerator. We would like this cleaning to be as simple as possible. The same applies to the loading of rubbish into the incinerator, which we would like to be able to be done automatically if possible.
3. All mechanical and eletrical works which includes but limited to supply, deliver and installation of all valves, penstock, screens, pumps, float swithces, flexible connector, pressure pipe works, blower, hot dipped galvanised lifting davits, air diffusers, hot dipped galvanised handrailings, hot dipped galvanised gratings, switch boards, cabling and wirings, lighting, earthing, metering, lighting protection, flow measurement and flow recorders, testing & comissioning and all necessary for proper completion and successful operational of the system.
