Problem

The Problem

Direct combustion disadvantage

Waste gas streams are often produced at low energy content (Lower Heating Values or LHV), insufficient to maintain direct flame based combustion without addition of other combustible gases. Direct combustion solutions therefore create a number of problems:

  1. Additional combustible gas requirement (NG, LPG or other) resulting in additional cost and at expense of additional CO2 emissions;
  2. High temperature combustion zone (temperatures above 1400 °C) resulting in, amongst others, NOx formation;
  3. Incomplete combustion resulting in formation of contaminants like CO, SOx, particulate matter (PM) etc..

Additional operating Cost
Environmental harmful emissions (S, N)
Difficult for energy recovery
GHG emissions (CO2, CH4)

Global Greenhouse Gas Emissions by Gas (%)

  • Nitrous Oxide
  • Methane
  • Carbon Dioxide (forestry and other land use)
  • Carbon Dioxide (fossil fuel and industrial processes)
  • F-gasses

2017 Global annual GHG emissions

Total: 49,3 MMtCO2 eq/yr
CH4: 6,9 MMtCO2 eq/yr

Pollution and waste-of-energy

The problems WTE-Tech targets to solve are:

  1. VOC emissions through waste gases being sent to air without further treatment;
  2. Emissions of contaminated fuel gases resulting from incomplete combustion and/or NOx formation;
  3. Waste of energy due to lack of energy recovery on LHV waste gas streams.
