  1. INFORMATION ABOUT COMPANY

As Ateş Refrakter (Fire Refractory) we have gained the trust of our customers by carrying out successful businesses in project, product selection, supply and application in the associations since 2011. We will continue to serve our valued customers in technical support issues such as project, product procurement, heat insulation calculations, refractory installation (including all over Turkey and abroad). It is an honor to serve you with a much wider range of products with your support.

 

Ateş Refrakter Incinerator usage areas;

 

  • Municipal Garbage
  • Medical Waste
  • Hazardous Wastes
  • Slaughterhouse Wastes
  • Airport Wastes
  • Chemical Waste
  • Industrial Wastes
  • Wastewater Purification Sludge
  • Oil Drilling Wastes

 

An incinerator; is a system that refines solid wastes and provides complete combustion at 1200-1400 ° C and does not release harmful gases in the atmosphere. The system has both front and end combustion cells. Solid wastes are burned in the front burning cell, and the gases produced from solid waste burning are burned at high temperature in the final burning cell.

 

If the waste is burned at temperatures below 800 ° C, harmful gasses occurs from the burning process. This system does not allow low combustion temperatures with the help of automatic control system. Because the system is fully automatic, the appropriate flue gas emission values remain constant as long as the prescription for wastes are followed regularly. 95% of waste incinerated in INCINERATOR is burnt-out. The resulting ash is not considered as in the category of hazardous waste.

 

Ateş Refrakter meets the requirements of Control of Medical Wastes Directive. The flue gas from the upstream and downstream combustion processes is discharged through the flue gas purification system in an odorless, colorless and environmentally harmless manner.

The device consists of the following sections;

  • LOADING UNIT
  • FRONT COMBUSTION CELL
  • FINAL COMBUSTION CELL
  • FLUE GAS PURIFICATION SYSTEM
  • DUST EJECTOR
  • HEAT EXCHANGER
  • LIQUID WASHING SYSTEM
  • CHEMICAL ADDING SYSTEM
  • FLUE GAS FAN
  • FLUE GAS FILTER (BAG FILTER)
  • FLUE
  • CONTROL BOARD
  • PNEUMATIC SYSTEM

 

2.1. LOADING UNIT

Completely automatic and PLC controlled design. The system consists of a pre-loading container and a conveyor system filling it. At the end of the preload; the oven front cover opens and is sent into the waste oven with pushers. 3 to 6 loads can be done every hour and thus the burning capacity can be reached.

 

2.2. FRONT COMBUSTION CELL

Front burner cell; loading lid, ash discharge lid, burners and explosion lid. The inside of the combustion cell is covered with heat-resistant refractor; the body is covered with steel plate on the steel frame. The heat generated in the combustion chamber is not allowed to escape with the help of special isolation material, so the heat losses are reduced to a minimum. The ash discharge lid in this section is used to evacuate ashes that form at the end of combustion. For any reason, the sudden increase in the volume of gas in the device is eliminated by means of the explosion closure.

 

2.3 FINAL COMBUSTION CELL

The combustion chamber is covered with heat resistant refractory. The heat generated in the combustion chamber is not allowed to escape by means of special isolation material, so the heat losses are reduced to a minimum. The interventional closure in this section is used to enter the final combustion cell during maintenance and is opened and closed with two tightening levers fully tightened. The final combustion cell is only used to burn gases from the front combustion cell. The general principle is pyrolysis (high-temperature decomposition and carbonization in a low-oxygen environment). In this method, the wastes are separated at the pre-combustion cell at 900°C and destroyed. The pyro gas formed at the end of the pyrolysis is destroyed by supplying fresh air at a temperature of 1200 ° C at a rate of 1.5-3 m / s in a specially equipped combustion chamber. The burner control is connected to the electronic control system. The sensors measure the temperature of the combustion chamber and command the operation of the burner.

 

2.4. FLUE GAS PURIFICATION SYSTEM

 

2.4.1 POWDER HOLDER (CYCLONE)

The most common dust separation system is cyclones. The cyclone is used to hold coarse particles present in the gases leaving the final combustion cell. The cyclone consists of a cylindrical body, a conical base from which the powders are collected, and an inlet which allows the introduction and rotation of the cylinder above the cylinder.

2.4.2. HEAT EXCHANGER

The heat exchanger is used to cool the gases from the final combustion cell at temperatures of 1200 ° C without entering the filter unit and to heat the gases from the filter unit before discharging it from the flue.

2.4.3. LIQUID WASHING SYSTEM

The liquid washing system consists of 2 wash towers. Flue gas washed with water in washing tower I, the heavy metals formed are washed in the basic solution in the washing tower II. Washing units are manufactured with corrosion and acid resistant material. If necessary, electric heaters can be placed under the washing cells to prevent the freezing of washing liquids, and the electric heaters are activated by the sensors to sense the decrease in water temperature. To replace the evaporation loss, the water is sent to the washing tanks by means of a floater. Washing is provided by 2 pumps in closed circuit.

2.4.4. CHEMICAL ADDING SYSTEM

It is necessary to add dust chemicals to the flue gas to keep the dioxins, furans and metals present in the flue gases. The most important heavy metals are mercury, zinc, cadmium and plumbum. These materials can evaporate at high temperatures in the pre-combustion and final combustion chambers. However, condensation occurs when the temperature drops after the system and forms particles as small as 0.5 microns in diameter. Various chemical mixtures are sprayed from the reactor to the flue gas to eliminate them. In this pneumatically operated system, the powdered chemicals placed in a tank that can be opened in the lid are transported into the flue gas with a special system. This process is done automatically by the control unit.

2.4.5. FLUE GAS FAN

Single-suction belt pulley with radial ventilator, with ball bearing, special shaft cooling to prevent damage to the bearings at high temperatures, cleaning cap and steel to clean particles that can form in the fan. The flue gas fan is designed and manufactured to work at high temperatures.

2.4.6. FILTER GAS FILTER (BAG FILTER)

The chemical mixture holding the heavy metals grows in volume and the bag is held here without passing through the pores of the filter. Thus, the mixture is prevented from being entrained by the flue gas.

 

2.5. FLUE

The harmless gases are released to the surrounding area, which have passed through the dry and liquid filters, are supplied to the outside by providing emission values of the flue gas.

 

2.6. CONTROL BOARD

The operation and control of all parts of the system is governed by the PLC system. The system informs about the breakdowns and malfunctions.

 

 

 

  • The volume of waste shrinks by 98%. Only ash which is composed of non-combustible materials between 3-7% of the weight and enters the non-hazardous waste class which does not present any risk remains.
  • All microscopic creatures (Hepatitis B, HIV, etc.) are completely destroyed.
  • Easy to use and safe.
  • The heat generated from the combustion is obtained from the heat.
  • Economic and long life.
  • Burning yield is 99.99%.
  • It does not need very large area. Hazardous wastes are destroyed before they go out.
  • There is no replacement part and service problem.
  • The system is fully automatic controlled by PLC, all information is displayed on the screen. In this way, the operator’s personnel have been removed.
  • Wet and harmful gases are trapped by wet and dry filter.
