Gas Turbine Filtration Solutions
The choice of major gas turbine engine suppliers and trusted by military navies around the world.
The marine environment represents a unique challenge for the operation of gas turbines and the air filtration systems that protect them. To ensure turbine protection, a filtration system is required to remove vast quantities of salt spray, dust and occasionally 'green seas', while being constrained by severe space and weight limitations.
Parker has specialized in the design and manufacture of advanced air filtration and silencing systems for gas turbines since the late 1960s when systems were first being introduced as propulsion units, principally on warships. When it comes to protecting the engines of crucial naval ships, the top engine suppliers turn to altair® for their filtration system needs.
Not only do altair filtration systems meet the specifications of OEM engine suppliers such as GE and Rolls-Royce, but continuous innovation in salt and water removal has helped earn the trust of key naval decision-makers. Our altair Neptune and altair Vega systems have been installed on major military navies worldwide and continue to be selected for new ship programs.
Heat Exchanger Solutions
One of the crucial requirements for systems on-board marine vessels and offshore platforms is to offer maximum duty in a minimal footprint. By using compact equipment, operaturos can realise significant savings in both upfront structural costs, and long-term operational costs.
Heatric Printed Circuit Heat Exchangers (PCHEs) combine high-integrity and offer a wide operating range of heat transfer duties in unti up to 85% smaller than competing technologies. The robustness, performance, compactness, and inherent safety benefits are key reasons tha Heatric PCHEs are a key enabling technology in a number of marine applications.
The benefits that Heatric PCHEs have brought to sea-going vessels and platforms makes them particularly well suited to use in marine propulsion.
Boil-Off Gas (BOG) Combustion
A key example of marine propulsion systems that can benefit from the use of PCHE is boil-off gas combusion. During transport of liquefied natural gas, an amount of the LNG evaporates due to temperature changes in the storage tanks of the carriers. In the past this evaporated gas was simply vented to atmosphere as it had to be removed from the tank to maintain pressure. It is now heated by compressors and burned in the main boilers as fuel. Heatric PCHEs are an integral part of the fuel gas supply system (FGSS) which preheats the boil-off gas to improve the efficiency of the fuel system.
With a range of benefits over traditional heat-exchanger technologies, Heatric PCHEs can be incorporated into these systems and a number of other duties where thermal effectiveness, compactness and safety are critical system considerations.
