Gardner Denver has been supplying efficient reliable vacuum systems to the electric power industry worldwide for more than 50 years. These vacuum systems can improve power station heat rates and provide economical solutions for environmental requirements.
Our broad range of air compressors can also cater for the diverse applications found in this industry .
Compressed air is used in all types of power generation plants. Compressed air is relied upon to keep processes running and high quality oil free air is the first choice in power generation as reliable sources of compressed air are critical in these plants. Downtime can cost thousands in lost product and penalties.
Positive displacement and truck blowers, hydraulic coolers, reciprocating and rotary screw compressors, air audits, petroleum and industrial pumps, vacuum and water jetting systems, air treatment and genuine replacement parts.
We manufacture, sell and service a complete range of world class rotary screw, piston, centrifugal compressors, including high-pressure, oil-free and portable models, and an extensive air treatment line.
Champion offers reciprocating and rotary screw air compressor systems, parts and service. Performance ranges from 1.8 to 255.6 cfm.
The Hoffman multistage centrifugal blowers and exhausters are capable of a variety of design options, field support, parts, accessories and lubricants to improve efficiencies in your application.
The Lamson multistage centrifugal blowers and exhausters are capable of a variety of design options, field support, parts, accessories and lubricants to improve efficiencies in your application.
A market leader in the manufacture and global distribution of rotary vane compressors, covering both air and gas applications. Performance range: up to 100 hp (75kW) and 474 cfm (13.43 m3/min)
Condenser exhausting involves the removal of air and other non-condensable gases from the steam space of power plant condensers. The purpose of removing these gases is to maintain the lowest possible turbine backpressure. The equipment used for this application is crucial to the efficient operation of fossil fuel and nuclear power plants.
Reliable, quality liquid ring compressors with the features and performance necessary for all demanding applications. Performance range: 0 to 15 mbar abs.
In order to start a thermal power plant, a condenser must be brought from atmospheric pressure to vacuum. In some systems, requirements preclude the use of the condenser exhauster to perform this job. In these cases, a separate vacuum device is used.
When flue gas is scrubbed to remove sulfur compounds, an aqueous slurry results. It is advantageous to remove the water from the slurry and handle only the solid material. This is done using vacuum filters. The liquid ring pump's ability to handle carryover from these filters makes it the ideal choice for this application.
This application consists of pneumatically conveying fly ash from the precipitator hoppers to a central dry collection point under vacuum. The main advantage of this type of conveying system is that since the ash is being conveyed under vacuum, any leakage is of air inward, and not ash outward. Liquid ring pumps are chosen for this application because of their ability to tolerate fly ash carryover into the pump.
Similar in application to condenser exhausting, geothermal gas removal involves the removal of air and other non-condensable gases from the steam space of the condensers. However, in geothermal power plants, the steam used to drive the turbine is extracted from the earth and contains large amounts of corrosive gases. The gases must be removed from the condenser in the most efficient manner possible.
High pressure oil free compressed air is used for pump turbine dewatering, pump to turbine blow down, governor and regulated control valve operation, surge suppression, water aeration.
Oil free reciprocating compressors for PET bottle blowing and industrial air and gas applications.
Providing a complete range of reciprocating compressors from bare block through to fully engineered solutions. Performance range: up to 1487 cfm (2527 m3/hr) and 6000 psi (414 bar).
Steam turbines employ a gland to seal the shaft against inward air leakage. In order for them to function as designed, excess gas and condensate must continuously be removed.
Boiler makeup must be deaerated prior to being introduced into the system. This is sometimes done in a vessel called a deaerator. A vacuum is pulled on the vessel and the makeup water is passed through it to remove all dissolved gases prior to introducing it to the system.
In this application, vacuum pumps are used to maintain a siphon in power plant cooling water systems. Maintaining a siphon allows cooling water circulating pumps to maintain design cooling water flows with minimum power consumption. Single stage liquid ring pump packages, often supplied with specially designed priming valves, are ideal for this application because they prevent ingesting of water slugs into the pumps.
With locations in 32 countries, Gardner Denver is strategically positioned to support its customers anywhere in the world.
