Baltec IES has progressively expanded its operations, and now has offices and agencies in 26 countries. We have strategically-located offices and agencies all around the world to cover the needs of our clients and market regions.
Supporting this extensive global presence is our network of strategic alliances and agreements with more than 20 top manufacturing locations. This allows easy and efficient transport to site, minimising freight costs.
We use state-of-the-art 3D design software to cover all aspects of our product development process with a seamless integrated workflow, including design, review, communication and data management.
We are proud to have a multidisciplinary team of experts specialising in structural, electrical, mechanical and acoustical areas.
Noise, flow and structural simulations are performed for every piece of equipment to ensure their reliability once they are built.
The main objective of Baltec IES is to provide top quality solutions to the gas turbine power industry.
We aim to achieve complete customer satisfaction by rigorously determining their exact requirements at the pre-tender and tender stages of a project so that these are met, including those of the product and service-related expectations such as on-time delivery.
We are and will always be part of the solution, not the problem.
Baltec IES provides its services for the whole life cycle of the project: from research and development, design and drafting to practical completion.
Our after-sales team provides full support during the lifetime of our products, as well as execution of retrofit projects and supply of spare parts.
A 360 Solution
Baltec IES designs and manufactures both static and pulse-type filter houses, together with the necessary support structures. Static filter houses use disposable cartridge-type filters, and typically incorporate two levels of filtration - a stage of coarse pre-filters, for removing any larger airborne particles, followed by a stage of fine filters. The number of filters used, and hence the overall size of the filter house, is selected based upon the minimum time required between filter changes, usually specified by the customer, and the dust concentration. Pulse filter houses use conical-shaped filters and feature an inbuilt filter-cleaning system, where each filter is periodically blown clean by a burst of compressed air. The advantage of a pulse filter house over a static filter house is that the filter elements will last much longer between changes. As with a static filter house, the number of filters used - and hence the overall size of the filter house - is selected based upon the minimum time required before the filters need replacing. Ductwork necessary to interface the filter house to the turbine, including expansion joints and silencers, can be provided if necessary.
Baltec IES undertakes extensive acoustic analysis on each project. When required, exhaust silencers are custom-designed to ensure the customer’s noise targets are met in terms of both near and far field levels, whilst at the same time providing maximum efficiency for the gas turbine, resulting in minimal pressure losses. The inlet and exhaust silencers can be provided as either horizontal or vertical flow types, depending on the geometry of the complete system and/or client preference.
These are 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. Baltec IES can provide guillotine dampers, either electric or manual operated, 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.
Baltec IES has the expertise and engineering capability to design and produce complete gas turbine bypass and HRSG exhaust system packages, including stack, silencers and weather (tack) dampers. This is a critical element in any combined cycle power plant as they allow the exhaust gases to escape to the atmosphere safely, as well as allowing the gas turbine to work efficiently by introducing minimal pressure drop to the system. Our exhaust stacks include access ladders, landing and ring platforms, as well as continuous emission monitoring ports on top of stack as per gas turbine manufacturer regulations.
A diverter damper is a large modulating valve and an important component of the bypass exhaust system. Baltec IES can customise and manufacture diverter dampers to suit any size of gas turbine. Diverters utilise an automated seal air system to guarantee 100% sealing efficiency and are available with either electric or hydraulic drive, supplied with a local control panel which also provides the interface to the plant DCS for full remote operation. Smaller diverters, with gas paths typically less than 3m x 3m, are normally direct-drive, whereby the diverter blade is driven directly by the hydraulic or electric actuator. Diverters larger than 4m x 4m are usually toggle-drive, utilising a linkage mechanism to reduce operating strain on the diverter blade and shaft. We have delivered orders for the biggest diverter damper ever built so far: a 6.5m gas path. For personnel safety and long product life, we design our diverters, elbows and exhaust stacks with cold shells, using a layer of ceramic fibre insulation between the inner stainless-steel liner and outer duct surfaces. This ensures the equipment has an exterior temperature typically less than 50°C, even with exhaust gas temperatures exceeding 680°C. Other alternative designs can be offered, such as warm and hot shell, depending on specific project requirements.
