Power Generation Provides Energy
In The Form of Plentiful Electricity
Over the past 50 years Sorensen Systems has established itself as an innovator in power generation design/build, particularly in the hydroelectric energy field providing turbine rehabilitation, governor conversion and station automation systems. Today, in partnership with Parker, it has expanded to meet the need for fuel-efficient, low-emission, high-performance energy from fossil fuel, combined cycle, combustion turbine and nuclear generation.
Using the latest technologies, the engineers at Sorensen Systems develop innovations to improve emissions performance, minimize waste, meet environmental regulations, monitor air and water quality, offer longer life, and help create greater fuel efficiency.
The four major types of thermal power generation are:
Partnering with Parker
Over 90 years ago, the Parker name was associated with its innovative braking system for trucks. Today, the $12 billion company sits in the Top 250 on the NYSE and is the undisputed leader in the manufacture and distribution of motion and control technologies for aerospace, industrial machinery, and high technology such as semiconductor and life sciences.
As an innovator for the power generation industry, it has over five decades of expanding expertise in components and systems for fuel and water atomization, fuel controls, emission controls, and fluid conditioning monitoring. The goal has been from the beginning to increase MW output, lower maintenance costs, extend engine and component life, reduce operating costs and lower emissions through greater fuel-burning efficiency.
Combustion Turbine Solutions
Combustion turbines are designed to start quickly to meet the demand for electricity during peak operating periods. Most combustion turbines are fueled by natural gas. Similar to a jet engine, combustion turbines draw air in at the front of the unit, compress it, mix it with fuel, and ignite it. The hot combustion gases then expand through turbine blades connected to a generator to produce electricity.
Plant operators are constantly seeking better combustion for cleaner-burning engines. Through application of the latest technologies, we can address some of the primary concerns that contribute to degraded performance in a combustion turbine. For example:
- Emission reduction – Advanced nozzle technology can help reduce NOx and CO from turbine exhaust
- Condition monitoring – Complete filtration, lubrication, and condition monitoring prevents damage to bearings, and monitors gearbox oil for particulates
- Expansion joints – Non-metallic, long-lasting performance for applications up to 1,800° on gas turbine inlet, exhaust, and HRSG systems
- Fuel control systems – Oil and gas fuel control systems improve gas turbine efficiencies
- Inlet fogging system – Patented single point nozzles provide the highest MW power augmentation in the industry
- Wet compression system – Uses high-pressure stainless steel filters, valves, fittings and spider nozzles to uniformly spray finely atomized demineralized water into the compressor inlet
- Siloxane removal system – The silicon dioxide buildup from biogas can be removed to reduce maintenance costs and improve efficiency
Combined Cycle Solutions
Combined cycle power plants are designed to produce electricity from two sources of energy instead of one. First, energy is produced by combustion of natural gas in a turbine, similar to a jet engine. Second, energy is also produced by making use of the jet engine exhaust to make steam. In this way, both methods drive turbines and electric generators to produce electricity.
Similarly to pure combustion turbine systems, plant operators of combined cycle systems are seeking modifications to sub-systems and specific components that improve overall plant efficiency. For example:
- Liquid fuel filtration – Special filtration components purify liquid fuel, removing particulates and water for improved reliability
- Hydraulic power units – A properly sized hydraulic power unit provides reliable, high-speed, and precise control for turbine fuel control valves, inlet guide vane actuation, and steam turbine electro-hydraulic systems
- Diverter damper controls – Specialty gas turbine hydraulic components and systems provide high-speed, high-accuracy diverter damper controls, fuel controls, and turbine controls
- Steam blowdown assembly – High-temperature steam blowdown and control valves offer industry-leading safety and reliability
- Nitrogen Generators - PSA and Membrane nitrogen generators for HRSG and boiler tubes limit corrosion during lay-ups, extending plant and component life
Fossil Fuel Solutions
Fossil Fuel plants use coal, oil or natural gas (in combination with air/oxygen) to create heat (thermal energy), which is used to create steam, which (under pressure) is used to turn the blades on a turbine engine, which drives a generator, which creates electricity. Sounds simple; yes?
What is not so simple is meeting some of the stringent demands of modern life, which includes the drive towards so-called Green technology, increased federal oversight and regulation and strong competitive forces on a worldwide scale. To meet these challenges, fossil fuel plant operators are seeking performance-enhancing components that improve system life, increase safety, eliminate time and cost, boost efficiency, and accurately meet standards for emissions compliance. Some examples are:
- High pressure pumping systems – Efficient pumping systems provide accurate flow and high pressure water for the flue gas desulphurization systems
- Steam control and instrument racks – We can provide fittings, valves, and manifolds that meet
B31.1 certification for the higher temperatures and pressures of supercritical boiler water control
- Continuous emission monitoring – We can provide control panels, fogging systems, and gas conditioning systems that provide accurate determination of gas emission levels to ascertain operation within defined control parameters
- Coal off-loading systems – A new hydraulic system for coal off-loading provides improved efficiency and faster throughput
- Oil monitoring system – Conditioning and monitoring systems for steam turbine lubrication and hydraulic systems maintain plant and equipment and improve system life
Nuclear Power Plants
Unlike fossil fuel, combustion, and combined cycle power plants, the nuclear power plant in New England is uncommon. Where there are hundreds of traditional power plants in New England, there are only two nuclear power plants in Connecticut and one each in Massachusetts, New Hampshire, and Vermont. Except that the source of the energy to create steam is nuclear fission, instead of burning coal, oil or gas, the rest of the power plant has the same demand for upgrading, improvement and efficiency.
Working closely with Parker, which currently provides components to 50 percent of operating nuclear plants in the world, we provide process control fittings, valves, regulators, hoses, and seals. Nuclear plant turbines use Parker's hydraulic accumulators, filters and specialty valves, while condensers and feedwater heaters use Parker fittings, regulators, seals and O-rings. Other systems provided to nuclear power plants include:
- Specialty valve systems – Designed to provide compliance with regulatory issues, retrofit for legacy equipment, and alternatives for non-critical systems
- CCIMS systems – An integrated manifold solution offers a precise, high-performance flow measurement and a quick disconnect replacement alternative reducing exposure to radiation
- Automated filter system – An automated purification system removes and disposes of the highly radioactive deposits that accumulate inside the piping, fuel pools, fuel transfers canals, and reactor feedwater
- Gas spring actuators – Used in safety-critical applications to operate main steam isolation, feedwater bypass, and emergency boration valves on pressurized water reactors
