Incineration of MSW - Coggle Diagram

- - - - takes 2 seconds
      - Flash pyrolysis
      - Temperature between 300-550 celcius
      - Char accumulates quickly
    - - Takes several hours to complete
      - Bio-char as main product
- - - - Technology range from simplest to sophisticated
        
        Simplest type
        
        Burn barrel
        
        Open pit
        
        Closed chamber
        
        single chamber
        
        retort multiple chamber
      - the quantity of the waste
      - The categories of waste
  - - - Remove certain waste components
      - Good combustion practices
      - Emission control devices
        
        Electrostatic precipitator
        
        Baghouses
        
        Acid gas scrubbers
        
        Activated carbon
        
        Selective Non-catalytic Reduction
        
        advantages
        
        volume and weight reduced
        
        air discharges can be controlled
        
        cost can be offset by heat recovery
  - - - use high pressure and high velocity air through sand-bed
      - Waste require segregation and size reduction
      - small feed rate of waste to ensure combustion efficiency
    - - Use to burn sludge
      - equipped with rotating shaft for combustion efficiency
    - - waste moving on sloping rocking grate in primary chamber
      - Direct fire beneath grate ensure high combustion efficiency
      - high ost in design, installation, power requirement
    - - rotary drum line with refractory
      - can incinerate with variety of waste
- - - - Generator Electricity
      - Hydrogen membrane separator
      - Biodiesel
      - Gas turbine or IC engine
  - - - Syngas is toxic and potentially explosives
      - requirement syngas conditioning and cleaning is costy
