Seven Immediate Energy Saving Ideas

1    Operate Boilers At or Close to Design Capacity. This decreases fuel consumption per unit of production and can result in an estimated energy savings range of 1 percent to 5 percent.  Likewise, if your facility or plant requires excess capacity, visit the Nationwide Boiler website to obtain a current list of boilers for rent or for sale.  Nationwide Boiler provides new and used boilers that can ship immediately, anywhere around the world (conditions apply, contact Nationwide Boiler for details).
2    Reduce Combustion Excess Air. Measure and control air-fuel ratio or oxygen and carbon monoxide content of flue gases from process heating equipment such as furnaces, ovens, and boilers for the entire range of operation. This has an estimated energy savings range of 2 percent to 15 percent. Think about installing a standard low NOx / low excess air burner (compared to an ULN / high excess air burner) on your boiler.  Complemented with a Nationwide CataStak™ Selective Catalytic Reduction System (SCR), a new burner retrofit and SCR installation will not only provide immediate energy savings, but will also reduce NOx emissions and decrease your carbon footprint.
3    Clean Heat Transfer Surfaces. Cleaning heat transfer surfaces lowers flue gas temperature and increases efficiency by improving heat transfer. Doing so can save an estimated 1 percent to 5 percent at a moderate cost.
4    Reduce Radiation Losses from Openings. Reducing radiation losses can save an estimated 1 percent to 2.5 percent at a relatively low cost.
5    Use Proper Oven, Furnace or Boiler Insulation to Reduce Wall Heat Losses. Reducing wall losses produces energy savings of 1 percent to 2 percent with only a moderate investment.
6    Insulate Steam Lines Leaving the Boiler as well as Air- or Water-Cooled Surfaces Exposed to the Oven or Furnace Environment. With an estimated energy savings range of 1 percent to 5 percent, piping insulation can be completed for a moderate investment.
7    Install Air Preheaters or Other Heat Recovery Equipment. This type of equipment recovers available heat from exhaust gases and boiler blowdown and transfers it back into the system by preheating. The potential energy savings range id from 1 percent to 25 percent, depending on process temperatures and other variables.  Consider a Nationwide Boiler EconoStak Economizer or a Heat Recovery (HR) Blowdown Pak to recover valuable heat that can be reused, allowing you to save money in the long-term.

Improving Boiler Efficiency

It is important for a boiler to run at its most efficient level in order to avoid costly issues and obtain the best results. Excess air is essential in boiler operation to minimize heat loss and improve combustion efficiency.  Here are some tips to help you make sure your boiler is running at the most efficient level possible:

  1. Periodically monitor flue gas composition and tune your boilers to maintain excess air at optimum levels.

  2. If there is a continuous blowdown system in place, consider installing a heat recovery system.

  3. If there is a non-continuous blowdown system, then consider converting it to a continuous blowdown system coupled with heat recovery.

  4. Reduce operating costs through maximizing the return of hot condensate to the boiler.

  5. If a condensate return system is absent, estimate the cost of a condensate return and treatment system (as necessary) and install one if economically justified.

  6. Repair steam distribution and condensate return system leaks.

  7. Insulate condensate return system piping to conserve heat and protect personnel against burns.

  8. Review your blowdown practices to identify energy saving opportunities.

  9. Examine operating practices for boiler feedwater and blowdown rates developed by the American Society of Mechanical Engineers (ASME). Considerations include operating pressure, steam purity, and deposition control.

  10. Consider an automatic blowdown control system.

WRBA and WTUI Trade Show Attendance in March

March is gearing up to be a busy time of year for Nationwide Boiler.  The company will be exhibiting at two trade shows, focused on boilers and steam turbines.

First on the list is the 44th annual Western Regional Boiler Association Conference, March 13-15th at the Davenport Hotel in Spokane, WA. Nationwide Boiler's Rental Manager, Michael Medina, will be on site to answer questions pertaining to Nationwide Boiler's complete line of rental boilers, new and used boiler systems for sale, emergency contingency planning and low NOx solutions.  The conference also includes presentations on topics including deaeration basics, steam turbine upgrades and emissions testing. Log onto WRBA's website for additional conference details.

Nationwide will also be attending the 2012  Wester Turbine User's, Inc. (WTUI Conference), held in Pasadena, CA at the Pasadena Convention Center from March 18 – 21st, 2012. Larry Day, Nationwide Boiler's Vice President of Sales and Marketing, along with Robert Remkes, Nationwide Environmental Solution's Vice President will be in attendance and on hand to discuss the CataStak™-GT SCR system for natural gas-fired turbines.  The CataStak™ has never failed a 3rd party source test and can deliver NOx emission reductions as low as 2.5 ppm NOx.  Stop by Nationwide Boiler booth number 622 to learn about the latest product news and equipment offerings by Nationwide Boiler.
