Economizer & Damper


To recover the waste heat from boiler flue gas Dexterous engineering offers customer Economizer. Flue gases from boilers are typically in the range of 230 – 345°C depending upon boiler pressure. Stack Economizers recover some of this heat for pre-heating water. The water is most often used as boiler make-up water or some other need that coincides with boiler operation. Stack Economizers should be considered as an efficiency measure when large amounts of make-up water are used, i.e. when there is no / low condensate return or there is a simultaneous need for large quantities of hot water for some process requirement. The savings potential is based on the existing stack temperature, the volume of make-up water needed, and the hours of operation. Economizers are available in a wide range of sizes, from small coil-like units to very large waste heat recovery boilers with lucrative payback & 5% fuel save option.

Dexterous Engineering offered Gas Diverter Dampers are employed in Gas Turbine Power Projects/Co-Generation Projects. These dampers are used to divert exhaust gas flow from the gas turbine either to HRSG or to Bypass stack side. The flow can be diverted either partially or fully. The dampers are provided with seals which are designed for 100% leak proof by providing seal air arrangements. These Dampers are operated by Electrical actuators, Hydraulic actuators, Pneumatic cylinders or manually with Gear Box. Dampers can be designed upto 1100 deg.C and pressure upto 5000 mmWC.
