| - Dry low emission (abbreviation DLE) is a technology that reduces NOx emissions that exhausts out of gas fired turbines. The amount of NOx produced depends on the combustion temperature.When the combustion takes place at a lower temperature the NOx emissions are reduced.Gas turbines with DLE technology were developed to achieve lower emissions without using water or steam to reduce combustion temperature (Wet Low Emission (WLE) technology).WLE technology demands cleaning of large amounts of water, is heavy, takes more space and can be difficult to install offshore.A DLE combustor uses the principle of lean premixed combustion, and is similar to the SAC combustor (Single Annular Combustor) with some exceptions.A DLE combustor takes up more space than a SAC turbine and if the turbine is changed it can not be connected directly to existing equipment without considerable changes in the positioning of the equipment.The SAC turbine has one single concentric ring where the DLE turbine has two or three rings with premixers depending on gas turbine type.DLE technology demands an advanced control system with a large number of burners.DLE results in lower NOx emissions because the process is run with less fuel and air, the temperature is lower and combustion takes place at a lower temperature.
