Transportable power generation

Mitsubishi Heavy Industries, Ltd. (MHI) has completed development of the MegaNinja1, a transportable power generation system driven by gas engine and configured like a container. The generator can begin power generation within 24 hours after its arrival at the site.

The MegaNinja1 incorporates all equipment necessary for power generation within an ISO 40-foot container, including a gas engine, generator, fuel gas compressor and control panel. The unit can also accommodate cogeneration through simultaneous use of a 20-foot container for waste heat recovery incorporating a hot-water heat exchanger and exhaust gas steam boiler.

Both types of container can be transported to their destination by trailer. MegaNinja1 has a generation output of 1,500 kW, and multiple units can be interconnected. MHI concluded a basic agreement with China’s Dongguan Xinao Gas Co., Ltd. on energy services utilizing MHI’s gas engine generation equipment, including two units of the MegaNinja1.

Siemens’ new steam turbine

At the PowerGen Europe conference in Cologne, Siemens announced a new enhanced platform design concept for steam turbines and its new SST-111 steam turbine. The enhanced platform design is for steam turbines with outputs between 15 and 250MW. It is said to increase efficiency and provide faster start-up, enhanced availability, a broader range of applications and ease of maintenance.

The SST-111 steam turbine is aimed at small, decentralized power generation facilities. With the SST-111, Siemens is extending its portfolio of compact steam turbines by adding a multistage machine for outputs up to 12 MW. The SST-111 combines the robustness and adaptability of a single-stage, geared steam turbine with the higher efficiency of a multistage steam turbine. The multi-casing design enables up to two controlled steam extractions to be provided for different industrial processes as well as for steam reheating. The first turbine will be delivered toViridorWasteManagement Ltd. and installed in a refuse incineration plant in Exeter in the UK.

Head-of-compression dryers

Ingersoll Rand has added an air-cooled model to the heat-of-compression (HOC) product line to allow for greater flexibility, energy efficiency and reliability.HOCdryers turn wasted heat into useful energy, resulting in clean, dry air at a fraction of the cost of traditional desiccant dryers. By using heat produced during the compression process,HOC dryers can deliver instrument-quality air using virtually no energy. The air-cooled model is an extension to the water-cooled HOC dryer released last year. These new models deliver Class 2 (-40 °F) air for customers that do not have a water source available yet desire the energy efficiency benefits afforded by the new HOC dryers.

Digital Torque Tester

The digital torque tester (DTT) from Snapon Industrial is a low-cost torque tester that can be mounted on a wall or in a bench-top vise to allow a technician to test torque wrenches and torque screw drivers. The DTT comes in 1/4”, 3/8”, 1/2” and 3/4” sizes, and features a touch screen pad to capture peak torque values during a test.All data can be downloaded to a PC.


Diaphragm Replacement Meter

GE launched the Dresser D800 Diaphragm Replacement Meter, designed for low-flow applications. The D800 offers the advantage of a 50% weight reduction (24 pounds vs. 50 pounds) and a 70% size reduction compared with previous products. The size advantage reduces the number of personnel required to transport and install the meter, in accordance with EHS standards.

Predictive control software

Rockwell Automation has added new tools to its Pavilion8 predictive control software, giving users the ability to create their own process models. Pavilion8 version 4.0 gathers all data from within a facility to develop a model of the process. The software assesses current and predicted operational data, compares it with desired results, and computes new control targets to reduce inprocess variability and improve process performance.

Milling tough pipe alloys

The Prepzilla Millhog features a robust construction with dual-opposed, tapered roller bearings, direct-drive gears, rigid blade-lock system and tin-coated-steel cutter blades. The clamping-end prep tool comes with a 1,800W motor that operates on 110/230VAC, and needs only one mandrel and eight sets of clamps for pipe from 40mm I.D. to 219 mm O.D. It is supplied with all clamp ribs and pads, a hose and filter, lubricator, and metal carrying case.

Soot modeling

Reaction Design has developed predictive soot modeling for gas turbine design. It is part of the company’s Energico simulation software, a physics-based modeling environment that delivers combustion simulations for gas turbines. .

GE Introduces PowerXpand

GE’s PowerXpand Portfolio consists of GE’s TM2500 and TM2500+ mobile aeroderivative gas turbine generator sets, the Jenbacher J320 containerized gas engine generator set and the V250/V228 diesel engine generator sets for rapid power. With start-up times of less than 10 minutes, the generator set can typically be brought from contract to commission in under 90 days.

Supercritical CO2 plant

Net Power LLC, Toshiba Corp., The Shaw Group and Exelon Corp. have joined to develop Net Power’s gas-fired power generation technology with zero emissions. The technology uses an oxyfuel, high-pressure, supercritical CO2 cycle, named the Allam Cycle, after lead inventor Rodney Allam. Unlike traditional carbon capture technologies, the Net Power cycle is said to produce pipelineready CO2 for sequestration or use in enhanced oil recovery without reducing plant efficiency or increasing costs.

The system provides methods for power generation using a high-efficiency combustor in combination with circulating fluid CO2. The CO2 can be introduced into the combustor along with a fuel and an oxidant for combustion, such that a high-pressure, high-temperature fluid stream is produced comprising the circulating fluid and combustion products. The fluid stream can be introduced into a turbine. The circulating fluid (at least a portion of which may be recycled from the fluid stream) can be passed through a heat exchanger to heat the circulating fluid prior to introduction into the combustor. Under the current program, a 25 MW natural gas plant is expected to begin operating in mid-2014.

Electronic pressure transmitter

SOR’s 805PT electronic pressure transmitter has achieved an IP68 rating in up to 100 feet of continuous submersion. (IP68 is the top rating for protection against dust and moisture.) With this rating, the submersible 805PT pressure transmitter provides precision depth measurements in liquid applications, such as well monitoring, ground water and surface water measurement, as well as municipal and industrial applications where watertight protection is required.

Hydraulic bolt closure

Boltight Ltd is supplying its Hydraulic Closure System to utility companies. The system is used for the temporary tightening of a steam turbine cylinder casing when performing rotor clearance, distortion and alignment checks (Tops on: Tops off). The system requires no bolt heating.

Borescope video camera

Almost any borescope can become a videoscope with the new Luxxor Portable Camera. Designed and made by Gradient Lens Corp., the camera allows users to view internal visual inspection images on portable or bench-top video monitors, or laptop or desktop computers. Video footage and still photos can be viewed as live, and saved, documented and e-mailed. The camera has a ¼” color CCD, built-in 25mm borescope couple, 768 x 494 pixel resolution, and is priced at $995.
