System and Automation Technique for Condensing Flue Gas Cleaning

 

Page 2 of 2

 

Algorithms developed by us

The programs are tailored for individual project requirements, as well as using our own pre-designed programs. These are based on process control algorithms from our extensive experience in many projects, e.g. to minimise the risk of corrosion in coolers and ducts.

For condensing with humidification the condenser plays an active part in the function of the combustion plant. By humidifying the air and flue gas, flows increase, pressure drops rise and the temperature in the combustion furnace drops. By controlling the rotation speed, the humidification can be varied and the combustion temperature optimised.

For plants without humidification, the control and automation system primarily handles the start-up and shutdown procedure and supervises important internal functions during operation. Such functions include the flow of cooling water, flushing of cooler inlet and pH control of the condensate by adding Lye or Lime. Furthermore the system reports operational parameters as pressure, temperature and cooler effect.
