At present, over 50,000 industrial gas turbines are in operation worldwide. Compared to reciprocating engines and steam turbines, gas turbines are steadily increasing their market share due to their lower maintenance needs, higher efficiency, and reduced emissions. These advantages make them a preferred choice in many applications where performance and environmental impact matter.
Industrial gas turbines are typically deployed in situations that demand high power-to-weight ratios, low emissions, and efficient operation. In the oil and gas sector, they are used for tasks like pipeline supercharging, oil pumping, water injection, gas lift, and power generation on offshore platforms. In these settings, lightweight design, durability, and reliability are critical, while efficiency takes a backseat.
Modern industrial gas turbines are complex systems with rotating components, bearings, seals, lubrication systems, and advanced control mechanisms. Because of this complexity, most users rely on original equipment manufacturers for maintenance and repairs, which can be costly and time-consuming.
However, there is a growing need for simpler, more cost-effective gas turbines that can operate reliably in harsh environments, require minimal training to operate, and are easy to maintain or replace. This has led to the development of a new centrifugal gas turbine prototype by engineers at the Southwest Research Institute (SWRI). The design addresses the limitations of traditional axial-flow turbines, offering a more compact and user-friendly solution.
Unlike conventional gas turbines that use axial compressors and turbines, the SWRI design uses a centrifugal approach. It operates on a simple open-cycle principle, consisting of three main parts: a compressor, a combustion chamber, and a turbine connected to a single rotating shaft. Air is drawn in, compressed, heated by fuel combustion, and then expanded through the turbine to generate mechanical output.
The key innovation lies in the layout: both the compressor and turbine are mounted on the same side of the rotating wheel, while the combustion chamber and nozzle are fixed within a shroud. This results in only two major moving parts, making the turbine easier to manufacture, assemble, and maintain. The radial flow design eliminates backflow, further enhancing reliability and reducing costs.
Overall, the SWRI centrifugal gas turbine is robust, compact, lightweight, and portable—ideal for applications such as pipeline cathodic protection, flare gas management, battlefield power, and auxiliary power on ships. The institute has already filed a patent for the design and is actively exploring commercial partnerships with manufacturers to bring this innovative technology to market.
Filter Press With Flex And Vibration
Filter Press with flex and vibration is suitable for materials with large viscosity and difficult to automatically fall off.
The filter cloth varicose system developed by our company can enable the filter press to change the inclination angle of the filter cloth during operation to form an inverted V shape, and at the same time, the springs held on the filter cloth expand and contract to generate vibration, so that the filter cake will fall off automatically. The varicose rod is made of reinforced polypropylene, which is light in weight, corrosion-resistant, flexible in movement and easy in maintenance. The varicose vibrating filter press is suitable for materials with high viscosity and difficult for the filter cake to peel off automatically.
This machine is widely used in wastewater treatment in various industries, such as food wastewater treatment, slaughterhouse wastewater treatment, meat processing sludge dehydration, cooked food processing factory wastewater treatment, soybean product wastewater treatment, urban sewage treatment, papermaking sludge dehydration , chemical fiber textile printing and dyeing sewage treatment, petrochemical sewage treatment and sewage treatment plants and other industries that require solid-liquid separation.
