IDEA Hosts Campus Energy Conference On Feb. 10-13

The International District Energy Association (IDEA) will present “Today’s Solution for Tomorrow’s Climate Challenges” as part of its 22nd Annual Campus Energy Conference on Feb. 10-13 in Durham, North Carolina.

While many campuses are currently facing budget cuts, declining endowments, and energy price volatility, the conference brings together hundreds of energy professionals to share real-world, practical insights on the most efficient and reliable campus energy systems in the world. By implementing some of these solutions, many campus utility directors, facility professionals, energy managers, and sustainability coordinators have an opportunity to capture energy savings through efficiency gains.

22nd Annual Campus Energy Conference Topics:

• Developing utility master plan processes from budget to completion
• Evaluating fuel flexible solutions while managing operating risk
• Assessing the utility master plan impact on Campus Carbon Footprint
• Evaluating technologies to reduce operating costs, cut emissions, and enhance reliability
• Finding federal and state funding resources to support project evaluation, design, and deployment

The conference will be held in conjunction with the Annual IDEA Distribution Workshop on Feb. 9-10. The workshop will feature panel discussions and training on safety, engineering, and maintenance of thermal distribution systems.

IDEA is a leading association dedicated to advancing global environmental quality through efficient district energy with more than 900 members worldwide. Benz Air Engineering is supporting the conference as an exhibitor. Benz Air has delivered patented engineering solutions that optimize efficiency and minimize emissions at several campuses, including the University of Texas at Austin.

Recognizing Heat As Energy Can Save Fuel

While most manufacturing operators understand that heat can be recovered from steam boiler blowdown to increase boiler efficiency and reduce fuel consumption, not every operator has considered the significant cost savings. In 2006, the U.S. Department of Energy (DOE) EERE released Steam Tip Sheet #10 to help manufacturers do exactly that.

The tip sheet estimates that a plant — where an 80 percent efficient produces 50,000 pounds per hour (lb/hr) of 150 pounds per square inch gauge (psig) steam, increasing its efficiency to 90 percent with a heat recovery system — could save $68,000 per year (assuming the 2006 fuel cost of $8.00 per million Btu). Benz Air Engineering solutions perform even better.

Case Study: A Condensing Heat Exchanger In Action

After evaluating the boilers at Del Monte Fruit Processing and Packaging Facility in Modesto, California, Benz Air Engineering recommended several improvements to two boilers that were operating at about 82 percent efficiency. One of these recommendations included the installation of a CondiMax Condensing Heat Exchanger, which converts previously wasted heat into energy.

The installation resulted in increased efficiency much higher than the DOE tip sheet. In fact, the heat exchanger reduced stack temperature to less than 100 degrees Fahrenheit while increasing boiler efficiency to greater than 94 percent. The installation also resulted in an energy efficiency rebate, which meant an immediate payback for the plant.

In November, Del Monte also received an award for its energy efficiency management program and sustainability efforts at its Modesto facility during the CMTA/Industrial Environmental Association/Chemical Industry Coalition of California’s Annual Environmental Summit. The two retrofitted boilers were highlighted for their ability to significantly reduce fuel consumption, NOx output, and wasted steam through recycling.

Del Monte Foods is one of the country's largest and most well known producers, distributors and marketers of premium quality, branded food and pet products for the U.S. retail market, generating more than $3.4 billion in net sales in fiscal 2007.

RGGI Hopes To Become National Cap-and-Trade Model

The Regional Greenhouse Gas Initiative (RGGI) will hold its second CO2 allowance auction on Dec. 17. Earlier this year, RGGI became the first mandatory, market-based CO2 emissions reduction program in the United States.

RGGI was designed to be a cooperative effort of ten northeast and mid-Atlantic states, including: Connecticut, Delaware, Maine, Maryland, Massachusetts, New Hampshire, New Jersey, New York, Rhode Island, and Vermont. It capped emissions for 233 plants by putting a price on the carbon dioxide they emit.

How The RGGI Cap-and-Trade System Works

• Establishing a multi-state CO2 emissions budget (cap) that will decrease gradually until it is 10 percent lower than at the start
• Requiring electric power generators to hold allowances covering their emissions of CO2
• Providing a market-based emissions auction and trading system where electric power generators can buy, sell and trade CO2 emissions allowances
• Using the proceeds of allowance auctions to support low-carbon-intensity solutions, including energy efficiency and clean renewable energy, such as solar and wind power
• Employing offsets (greenhouse gas emissions reduction or sequestration projects at sources beyond the electricity sector) to help companies meet their compliance obligations

The market opened in September as part of a $1.1 billion pilot project. RGGI hoped the success of the program may serve as a nationwide model to stem global warming. While it is clear President-Elect Barrack Obama has committed to a national cap-and-trade system, it remains unclear whether such a national system would model RGGI or incorporate other state efforts, such as AB-32 in California.

In the first auction, a total of 44 entities won allowances and the bid prices
ranged from $1.86 (the minimum bid allowed) to $12.00. A post settlement of the first auction is available here.

An Engineering Abstract for San Joaquin Valley Boilers

Looking out over the quiet rolling hills, it almost seems pastoral in the San Joaquin Valley these days. Many of the processing boilers have been shut down and laid up for the season.

But while some people are hibernating, I know the best boiler operators are taking action and caring for their equipment, demonstrating what I can only call a deep affection for detail.

Some of them have to, but many of them just think like me. A 180 mmBTU/hr boiler is more than just a piece of equipment and it never gets the appreciation it deserves.

You see, when most people look at a boiler, they only see some big piece of equipment. They think it costs too much to feed. They complain that it's never quiet, operating every minute of the season. They blame it for arguments because no one ever seems to agree how hard it should work. And lately, everybody says that it pollutes the air too much.

As an engineer, I think about boilers differently. Sometimes, I even ask myself what a boiler might dream about if a boiler could have dreams. Seriously.

I think a boiler might dream about NOx control and boiler efficiency. Or maybe it might dream about acquiring super powers like those super boilers at the University of Texas. Or maybe it would dream about making a transformation during the winter months, allowing it to do anything everyone wants — more steam, even more steam, not so much steam, and so on — all within seconds. Or maybe about using 12 percent less fuel. Or maybe reducing emissions.

Anthropomorphic excursions aside, most boilers need retrofits to become super boilers.

They have to. As NOx regulations reach the strictest possible level and energy costs continue to rise, the only solutions are to take advantage of the energy efficiency incentives available right now and retrofit these boilers well ahead of schedule for immediate cost savings and a faster payback.

In fact, with the right team, the payback on investment is remarkably short — sometimes as little as two years or less. Now you don't have to be an engineer or a boiler operator to appreciate that. But if you're still not sure, then subscribe to some of the case studies and solutions we'll be sharing in the weeks and months ahead.
