Our Products
Inlet Filter Houses
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.
Fogging Systems
OptiMist Fogging Systems
These are an extremely effective yet low-cost option for increasing the MW output of the Gas Turbine. The OptiMist system works by injecting an atomised water mist into the inlet ductwork upstream of the turbine compressor. The water mist instantly evaporates, thereby cooling intake air and increasing air mass flow rate entering the turbine. The pumps and control system are mounted on a skid at ground level, normally adjacent the turbine, whilst the high-pressure spray manifolds and nozzles are fitted inside the inlet ductwork. Turbine downtime to fit the system to an existing installation is less than a week. Each OptiMist system is custom-designed based on the average climatic conditions at site. In operation, the optimal level of cooling (i.e. water flow rate to the nozzles) is constantly calculated and adjusted by the OptiMist control system, based on current ambient conditions. An additional larger pump is normally supplied with the OptiMist system to provide overspray, where more water is sprayed into the inlet air. Gains of up to 5% may be achieved using overspray.
Silencers
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.
Acoustic Barriers
In addition, we can supply industrial sound barriers to reduce the noise from different strategic sources. This is a low-cost and easy-to-install solution which are designed for maximum noise abatement. Panel walls are filled with sound-absorbing materials, selected according to a case-by-case basis to achieve best noise attenuation results. These panels can be fabricated to any size and their installation/removal kept simple.
Guillotine Dampers
Bypass and HRSG Exhaust Stacks
Heating & Cooling Systems
Evaporative Cooling & Chiller Systems
Evaporative cooling works by drawing turbine inlet air through a stage of evaporative media fitted downstream of the combustion air filters. The media is kept wet consistently by pumping water up from a storage tank at ground level. The air is naturally cooled as it passes through the media by water evaporating from the media surface. Chillers work on the same principle as refrigerators, passing the inlet air past a set of heat-exchanger pipes that are kept cold by the circulation of refrigerant gas or chilled water. Baltec IES supplies electric centrifugal chiller systems or absorption chiller systems powered by exhaust gas, fuel or steam.
Heating Systems
For harsh cold environments, including Arctic regions, Baltec IES provides innovative solutions for Heating Systems in Filter Houses. Baltec engineers can deliver custom designs for all environmental conditions on a case by case basis.
Diverter Dampers
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.
