DEKKER at POWER-GEN 2017: Back to Basics

Michigan City, IN [November, 2017] – POWER-GEN International, the world's largest power generation event, announced that it is “going back to its roots and will cover ALL forms of power generation.” One important aspect at the root of almost all power generation is the need for vacuum technology. DEKKER Vacuum Technologies has been fulfilling that need for nearly twenty years.

DEKKER, a world leader in vacuum solutions, and a valued supplier for the power industry, returns to POWER-GEN as an exhibitor at the 2017 event.

Representing DEKKER at booth 11118 will be:

- George Harding, Director of Power Generation Sales
- John Hyrb, PE, PMP, East Coast U.S. Business Development Manager
- Rodney Weeks, Western U.S. Business Development Manager
- Rae Isbell, Applications Engineering Manager

POWER-GEN 2017 will take place in Las Vegas, Nevada, from December 5th - 7th, 2017. Offering comprehensive coverage of technologies and issues, the event will welcome more than 20,000 delegates from 106 countries, including the U.S., Canada, China, Mexico, Japan, Germany, United Kingdom, Saudi Arabia, Brazil and India, more than 200 industry experts, and more than 1,400 exhibiting companies.

DEKKER and Vacuum Technology: At the Core of Power Generation

According to POWER-GEN, the forms of energy used at attendees’ power plants are natural gas (21%), oil (14%), coal (11%), solar  (10%), wind (9%), biomass (8%), hydro (8%), nuclear (7%), waste (7%), marine and hydrokinetic (MHK, 2%), and other (3%).

“Our primary area of attention is the energy conversion process,” said Harding, who will be leading the DEKKER delegation. “Whenever the energy sources (gas, oil, coal, solar, biomass, nuclear and waste) are used to generate steam, the plant will use most, if not all, of the applications of vacuum technology.”

DEKKER vacuum applications for the power generation industry are:

  • Condenser hogging: removing air from condenser at plant start-up 
  • Condenser holding: removing air in-leakage to maintain condenser pressure during power generation
  • Deaeration: mechanical removal of dissolved gases from water used in boiler  feedwater to prevent corrosion
  • Degassing: removing gases such as volatile organic chemicals (VOCs) from liquids or solids
  • Flue gas desulfurization: removing sulfur dioxide (SO2) from flue gases of fossil-fuel power plants
  • Fly ash conveying: transporting fly ash via suction to a collection center (baghouse)
  • Priming: removing air from the casings of centrifugal pumps or from condenser water boxes
  • Transformer oil purification: removing water, gases and particulate matter from oil used to insulate transformers or to lubricate other equipment (also called dehydration or drying)
  • Turbine gland exhausting: putting turbine shaft glands under vacuum to prevent air from leaking into the turbine

By far, the most critical applications are hogging and holding.

DEKKER Systems: Tested, Proven

The Heat Exchange Institute (HEI) states: “Today, vacuum equipment, such as liquid ring vacuum pumps, steam jet ejectors, and hybrid systems, are used for numerous applications in all types of power plants. The proper operation of a power plant’s vacuum system is essential to the proper operation of the entire plant.”

“The power generation industry has always been one of the most demanding tests of performance and reliability of vacuum systems.” said Harding. “Our customers tell us DEKKER systems meet or exceed their toughest requirements.”

DEKKER’s premier power generation technology is the AquaSeal POWERGEN two-stage liquid ring vacuum pump system. AquaSealPOWERGEN is the industry standard for condenser exhauster applications, with components and accessories specifically used for condenser hogging and holding applications.  AquaSeal offers superior advantages in condenser pull down, vacuum level, handling liquid carry-over, durability, low operating costs and minimal maintenance.

The standard AquaSeal system provides a more economical design for deaeration, flue gas desulfurization, fly ash conveying and priming.  

A key advantage of AquaSeal is performance that results in financial savings. Excess leakage can cause condensers to become “air-bound” and lose efficiency. Improving condenser vacuum by even a half-inch of mercury (0.5” HgA) can result in substantial savings. For example, a plant rated at 500 megawatts, operating 8,000 hours per year (at a price for natural gas of $3 per million BTUs) could potentially save more than $300,000 per year.

DEKKER complements AquaSeal with its powerhouse Maxima-K™ large capacity single-stage vacuum pumps for condenser hogging and fly ash conveying applications, and the TiTan™ water-sealed liquid ring vacuum pump system for water box and pump priming.

DEKKER: Solid Support in an Industry Under Transformation

As power generation companies face rapid and significant change in the U.S. electricity sector, Harding expects to emphasize DEKKER’s expertise at POWER-GEN.

DEKKER offers “Gold Standard” technical support, a knowledge-backed guarantee dedicated to resolving system challenges, streamline processes and optimize results. This full service is maintained for the life of the client relationship.

Personal support is as significant as the technology. Harding, for example, has more than 35 years’ experience in the vacuum industry, and specializes in condenser exhauster and evaporator vacuum applications. He said, “We can apply an unrivaled depth of engineering skills to innovate solutions that specifically address the individual challenge or opportunity.”
