Cutting-edge engineering solutions
Complete Inlet & Exhaust Systems for Gas Turbines
Access Systems - Inlet
Stairs, ladders and platforms are provided to access the various levelsof the filter house for maintenance, testing and filter element replacement. |
Weather Hood
Located at the front of the inlet filter house prevent rain and snow entering the filter house. Often house a bird screen and sometimes pre-filters. |
Filter Module
Inlet filter module contains all the individual filters that filter the air. The filters are field replaceable and can be panel type or cylindrical. Filter module can have a pulse cleaning system for dusty environments. |
Inlet Ducting
Inlet ducting directs clean air from the filter module to the gas turbine inlet plenum. |
Inlet Silencer
Inlet Silncer attenuate the noise emitted from the turbine compressor. |
Acoustic Enclosure
When noise needs to be limited more that the shell insulation is able to attenuate. |
Inlet Expansion Joint
A flexible connection between the inlet filter house and gas turbine inlet. Ejs allow for thermal expansion and alignment of the different components, allowing movement in the vertical and horizontal directions. |
Gas Turbine
Baltec systems are adapted to all makes, types and sizes of turbines. Baltec supplies to all the major gas turbine manufactures, EPCs and end users. |
Exhaust Ducting
Direct hot gases from the gas turbine to the diverter or exhaust stack |
Diverter Damper
Used in combined cycle applications directs gas up through an exhaust stack or to the HRSG. |
Guillotine Damper
Provides a secondary shutoff after the diverter damper to prevent any hot gases entering the HRSG. Allows maintenance work on the HRSG while the GT is operating. |
Exhaust Expansion Joint
A flexible connection between the gas turbine and the exhaust system, between the HRSG and the exhaust system and the diverter damper and the bypass stack. Ejs allow for thermal expansion of the different components, allowing movement in the vertical and horizontal directions. |
Exhaust Silencer
Attenuates the noise from the gas turbine exhaust system to comply with environmental noise limit requirements. |
Exhaust Stack
Directs the exhaust gases from the gas turbine to the atmosphere at an elevation safe for the surrounding conditions and ensure proper plume dispersion. Cold shell design that is customised for the site conditions and customer requirements. |
Support Structure
Supports the stack above the Diverter damper. Also for supported stacks that have an elbow to allow for future conversion to combine cycle. |
Access Systems - Exhaust
Stairs, ladders and platforms are provided to access the various levels of the stack and guillotine for maintenance and Emissions testing. |
Our Product Range
Engineering at its Best
Silencers
We specialise in comprehensive acoustic analysis for projects, custom-designing exhaust silencers to meet noise targets efficiently.
We specialise in comprehensive acoustic analysis for projects, custom-designing exhaust silencers to meet noise targets efficiently. These silencers ensure minimal pressure losses while achieving near and far field noise level requirements for gas turbines exhausts, inlet filters and other high flow. We also provide industrial sound barriers as a cost-effective solution for noise reduction from various sources. Provide silencers for gas turbines in the range of 10MW to 500MW, both horizontal and vertical silencer, circular or rectangular.
Guillotine Dampers
Used whenever a secondary isolation of the HRSG ducting is required during maintenance works, and are fitted downstream of the diverter damper in a typical Bypass Exhaust System.
We can provide guillotine dampers, either electric or manual operated, and fully automated with the option of providing a Seal-Air System independent of the diverter damper. Custom-designed guillotine dampers can also be supplied for many industrial processes other than isolation of gas turbine exhausts.
Bypass & HRSG Exhaust Stacks
We excel in the design and manufacturing comprehensive packages for gas turbine bypass and HRSG exhaust systems, encompassing stacks, silencers, and weather dampers.
A crucial component in combined cycle power plants, these systems ensure safe exhaust gas release to the atmosphere and enable efficient gas turbine operation with minimal pressure drop. Our exhaust stacks feature access ladders, landing and ring platforms, and comply with gas turbine manufacturer regulations, incorporating continuous emission monitoring ports on top.
Inlet Filter Houses
We design static and pulse-type filter houses, complete with essential support structures.
Static filter houses utilise disposable cartridge-type filters, featuring two filtration levels – coarse pre-filters for larger particles, followed by fine filters. The size is determined by the required interval between filter changes. We also provide necessary ductwork, expansion joints, and silencers for turbine integration if needed.
Evaporative Cooling Systems
We employ evaporative cooling by drawing turbine inlet air through wet media, naturally cooling it as water evaporates as well as for extreme cold climates, we deliver innovative Heating Systems for Filter Houses.
Our engineers provide custom designs suited to specific environmental conditions on a case-by-case basis.
Diverter Dampers
Engineering custom diverter dampers for gas turbines, ensuring optimal sizing for any application, providing a sealing efficiency of 100%.
Our portfolio includes the delivery of the largest diverter damper to date: a 6.5m gas path.
Our designs incorporates cold shells with ceramic fibre insulation for diverters, elbows, and exhaust stacks. This design maintains an exterior temperature below 50°C, even with exhaust gas temperatures exceeding 680°C.
Heating & Cooling Systems
We design and install chilling coils inside inlet filter houses to improve the gas turbine performance on hot days.
We also install heating piping (steam or hot water) inside the inlet filter houses to improve part load performance on gas turbine and provide anti icing capabilities when air temperature is below 4oC.
