Waste-to-energy: Combustion Thermal Monitoring

WASTE-TO-ENERGY PLANTS: OPTIMIZE COMBUSTION PROCESS OF WASTE INCINERATORS

Converting waste into energy such as power and heat through combustion is an innovative process reducing our impact on the environment. The main challenge of incineration plants is to increase the waste-to-energy efficiency by monitoring each step of the process. One of these major steps is the combustion process on grate furnaces. Its optimization increases the steam output vs. ton of waste burnt, as well as the quality of the slag to make it more valuable. HGH’s Pyroscan visible and thermal camera monitors this process providing key data to the plant control system.

The Pyroscan camera is a heat resistant thermal imager providing a real time and accurate temperature measurement of the burning zone. Two possible configurations are available.

Combustion Thermal Monitoring

PYROSCAN SERIES: HIGH TEMPERATURE CAMERAS

  • PYROSCAN with water cooled endoscope to capture images close to the burning process without attenuation of signal.
 
 
  • PYROSCAN-U installed outside the high temperature burning zone of furnaces, looking at the calcination area through a standard window. No cooling means is required for this model.

INTEGRATED SOFTWARE FOR VISUAL AND THERMAL MONITORING OF THE COMBUSTION

Whatever the model, the PYROSCAN thermographic camera comes with the Pyromancer software processing the images and providing powerful tools to user to analyse the temperature data of the burning process through a simple and intuitive HMI. The Pyromancer software also includes features dedicated to the waste-to-energy conversion application process:

  • Real-time and simultaneous display of the visible and thermal image
  • Interface with the Plant Control System through OPC link and 4-20 mA
  • HGH’s exclusive flame front location measurement function

FOCUS ON THE FLAME FRONT FUNCTION – BENEFITS FOR THE USER

The accurate control of the location where the combustion stops, or flame front, is of paramount importance for the effective operation of the installation. To that aim, HGH has developed a dedicated algorithm specially designed in partnership with worldwide leaders in waste incineration to provide accurate and real-time flame-front detection in grate furnaces of waste-to-energy plants. The location of flame front is transferred in real-time to the furnace control system which will adjust the speed of the grate and the air flow in various areas, and which will turn on burners if needed.
