Key Performance Indicators (KPI) of an incinerator

A standard to compare different type of incinerators always apply to a specific type of waste and the price which need to be paid for consumables and for residues. Waste incinerators are mainly designed and sized on the basic charachteristics of waste :

  1. Calorific value of the waste (MJ/kg), mass throughput (kg/h) and size
  2. %Cl content in the waste (m%Cl)
  3. %S content in the waste (m%S)
  4. %N

Consumables are chemicals, like Sodium bi Carbonate, hydratated line, Caustic soda and activated carbon are the most common. But also water, diesel or gas, electricity are consumables of a waste incinerator.

Residues are directly conneted to the type of design and the strategic choose of the investor to design it. Residues mainly are :

  1. Bottom ash from the incinerator
  2. Fly as from the boiler or quench
  3. Fly ash from the bag house (contaminated with chemicals)
  4. Water purge from a wet scrubber 

Residues are also price choosen.

Keeping the above conditions into account mainly for economical reasons, a good incinerator need to be designed that :

  1. Health and the safety of workers and people arround is guaranteed
  2. Unplanned downtime is minimalized
  3. Consumption of chemicals and production of residues is the min. possible assesment for the environment
  4. Min. amount of emission limit overshoot
  5. Productivity per shift is reaching the correct amount per shift
  6. Transparancy to the environmental autorithies
