Engine & Turbine Technology
Te FT4000 is designed for simple- cycle, combined-cycle, or cogeneration applications. Te free-turbine design allows for flexible power plant operation down to 25% of full load, synchronous condensing operation without a clutch, and spinning reserve capacity. Te unit will be delivered later this
year, with commercial operation slated for May 2015. Distributed power generation specialist
Dresser-Rand showcased its new Guascor biogas engines at the recent Green Expo trade fair at the Mexico World Trade Centre in Mexico City.
Te SFGLD engine series was specifically developed to work with natural gas, biogas (landfill, sewage, biogas from anaerobic digestion processes), or gases from biomass gasification processes. Te engines can be equipped with mechanical or electronic carburetion control and are adaptable to any type of low heat value (LHV) gas. Tey have been successfully tested with product gases from many different sources, including landfills, waste water treatment plants, animal manure digestion processes from cows, pigs, chickens, farm waste, cassava, starch, wine dredges, palm oil mill effluent, and more.
Te engines, which range from 140 to 1240kW can be supplied as a bare engine, generating set, with cogeneration systems (CHP) separately, or in a fully assembled container unit (noise insulated if required).
Dresser now offers: the naturally aspirated FG Series of lean burn engines; the mechanically carbureted FGLD Series of lean burn engines; the electronically carbureted SFGLD Series of lean burn engines from 240-985kW (322-1321HP); the electronically carbureted Miller cyle SFGM Series, from 1055-1100kW (1415-1475HP); and the Miller cycle high efficiency HGM Series, from 520- 1350kW (697-1810HP).
Te company also offers single- and multi-stage steam turbines. Tese provide a variety of mechanical and power drive solutions for many industries. Designed to drive generators for independent power plants, compressors and other mechanical equipment for industrial processing and institutional power plants, Dresser says the turbines offer proven reliability and high efficiency. Available in a number of design configurations, these steam turbines are ideal drivers for process compressors, centrifugal pumps, fans, and blowers used in food processing, ethanol, waste-to- energy, petroleum, petrochemical, paper, biomass, and other industries. Dresser says the single-stage steam
workhorse turbines are cost-effective, easy to install, come in a variety of sizes and configurations, require minimum maintenance, and are designed for extremely high inlet pressures and temperatures, as well as high exhaust pressures. In addition they meet the requirements of API 611 and 612. l
Weir and MTU to jointly develop power systems for fracking W
eir Oil & Gas and Rolls-Royce Power Systems company MTU have signed an agreement to develop power systems specifically engineered
for hydraulic fracturing. Weir is a manufacturer of hydraulic fracturing pumps
and MTU a leader in heavy-duty industrial diesel engines. The system will be used for hydraulic fracturing operations during the well completion stage of shale oil and gas projects. The first fully integrated power system is expected to be
available to customers in mid-2015. The agreement outlines the companies’ plans to work
together to address the market need for more reliable and continuous duty equipment. A team of engineers is concentrating on optimising the interface of the three most critical components — the engine, transmission and fracturing pump — to truly work as one system.

Further, the complete packaged power system will utilise smart controls that provide conditioned monitoring and optimised performance for the operator. The Weir-MTU announcement builds on Weir’s
innovative SPM pumping technology and the performance of the new MTU Frac Pack, which integrates the MTU Series 4000 T95 diesel engine and the ZF 8 TX transmission. According to Weir Oil & Gas divisional MD Steve Noon,
the new relationship will utilise the best technology and service capabilities in the market to provide a total integrated offering. “This innovative approach will introduce a complete
package, with all components built specifically for fracking applications, integrated and optimised to work together, have longer run times and provide greater efficiencies for our customers. It is something the industry has asked for and we are determined to deliver,” he said. l
GE’s TM2500+ gas turbine is capable of providing ISO-rated 31MW of fast and reliable on- site generating capacity.
The new FT4000 Swiftpac gas turbine generator package offered by PWPS produces the highest output of any aero-derivative engine while maintaining high efficiency. The powered by a Pratt & Whitney PW4000 derivative gas generator, offers a 60- 120MW package of reliable peaking and base-load power in a compact footprint.
