Turbomachinery Package Specification

Titan 250 Generator Set

 

 

For combustion, the gas turbine requires approximately one-fourth of the total air it compresses. The excess air is mixed with the combustion products to reduce the gas temperature at the turbine first stage-inlet. The cooling air also keeps metal temperatures in the combustor and turbine assembly relatively low to ensure a long service life.

Figure 4. Typical Combustion Process3.1.2SoLoNOx Combustion System

The Titan 250 incorporates Solar’s proprietary SoLoNOx dry emissions system that reduces pollution by limiting the formation of nitrous oxides (NOx), carbon monoxide (CO), and unburned hydrocarbons (UHC). This system uses lean premix combustion to lower the maximum flame temperature and reduce pollution formation. Solar’s engineering staff will work with the customer to meet local permitting emission requirements.
