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.
incinerators plants
In the process of developing a project, we came across an issue, which is the estimate cost of incinerators plants (capable to destroy chlorinated in an environmental friendly way – please provide cost estimate/price range of incinerator plant).
- What kind of waste is to be burned?
- In which country the incinerators have to be installed?
- What about the amount of waste to be burnt per hour/day/week or per cycle?
- Ozone depleting Substances (chlorinated gas, CFC-11/12, HCFC-22 and similar mixtures), POPs (Polychlorierte Biphenyle mainly). Temperature of over 1200C is required.
- 150 MT of POPs (PCB) 210 MT of ODS for 3 countries in 2 years. Therefore it would be good to know the connection between price and capacity. (starting from 1 t/day for X USD till 10.000 t/day for XXXXUSD)

Burners temperature controlled (TIC – Thermocouple) and work on ON –
OFF basis. The frequency on ON – OFF will depend upon the nature of
waste, moisture content, calorific value, etc. and shall vary from waste to
waste. The fuel consumption also depends upon the frequency of the door
opening and method of operation of the incinerator. We have mentioned
approx. expected fuel consumption figures.

ii. 1 No. fully automatic Fuel Oil burner for secondary chamber.
III. Centrifugal forced draft fan assembly complete with motor drive, duct and
dampers, etc. mounted on the common skid of the unit to provide :
Combustion air.
Eductor air.
IV. Eductor Assembly for :
Cooling of exhaust gases from 900 – 1000 0 C to around 350 0 C .
Keeping the entire system under negative pressure to avoid hot gases / dust
particles rushing out of charging door.
V. Electrical Control Panel along with safeties, and Audio / Visual
indicators and
/ or alarms for efficient and safe operation of the system.
VI. Electrical wiring of the unit.
VII. Oil tank of 1000 ltrs capacity mounted on the skid
VIII. Operating tools and tackles comprising of – rake, hoe, shovel (I No. each).
IX. Chimney of 2.5 Mtr height.
