What's New

• Seneca Foods Reduces Fuel and Electricity Costs with XPlus Burner and Controls Retrofit
• 11 November, 2011
• Preferred supplies equipment and expertise to save over $50,000 per year of fuel and over $3,000 worth of electricity with a new burner. The reduction in natural gas consumption would reduce the plant's carbon dioxide emissions by over 600,000 lbs per year. In addition, up to a quarter of the heat input of this burner comes from the digester gas produced from corn and bean waste produced by the cannery.

• Generator Fuel Systems Affect Uptime
• 11 November, 2011
• Whether for a data center, health-care building or 911 call center, a great deal of time and effort are put into the design of the emergency backup generators, switch gear and UPS equipment that supply emergency backup power. Often very little attention is given to the design of the fuel oil supply system necessary to run the generators. A badly designed fueld system can cause a power interuption just as certainly as a failure of the the downstream equipment.

• Understanding Fuel Savings in the Boiler Room
• 09 November, 2011
• Because of their relatively low capital cost and high impact on boiler efficiency, burner and combustion control retrofits offer boiler owners the quickest paybacks based on energy savings.

• Diesel Generator Failures: Lessons Taught by Hurricanes
• 09 November, 2011
• Understanding the reasons generators failed during recent hurricanes and applying some of the lessons learned may help ease future emergencies.

• The Case for Draft Controls: Then and Now
• 04 January, 2011
• Modern draft controllers are easy to set up, have large easy to read displays, and are pre-programmed to include all the essential draft control functions. Although the requirements for draft controls have changed over time, their installation in certain combustion applications has remained a constant over time.
