Food for Thought

With the holidays just around the corner, Nationwide Boiler was inspired to collect food donations to help fight hunger in our local communities. We just wrapped up our 2nd Annual Holiday Food Drive, this time supporting the local food banks in both Fremont, CA and Washougal, WA. Our offices collected the most needed items requested by the Alameda County Food Bank and Inter-Faith Treasure House. Our goals were set to surpass the amount of food collected from last year, and the results were positive. Pacific Combustion was able to collect over 10 bags in Washougal, and in Fremont we filled four barrels full of food. Each of these Food Bank provided barrels are equivalent to about 125lbs of food, if filled to the top. Four full barrels means we donated roughly 500lbs of food along with the added amount from Washington. Way to go team!

Inter-Faith Treasure House has been in business for over 49 years and has provided food and assistance to Camas and Washougal residents in need. Majority of the business is funded and runs with the help of volunteers and donations. Treasure House administers several outreach programs for families in crisis and the food we have donated is going to help support these families. 

The Alameda County Community Food Bank or “ACCFB” distributes millions of healthy meals every year, and they are on the forefront of new approaches to ending hunger and poverty. For over 30 years they have stood by the belief that food is a basic human right and no one should worry about their next meal. The estimated 500lbs of food donated will go directly to the ACCFB and contribute towards their mission statement of ending hunger and poverty. We are always encouraged to see Nationwide employees come together to  support a good cause. The multiple bags and barrels we filled will fill the bellies of many in need.

Nationwide is always looking for opportunities to lend a helping hand and contribute to local nonprofits. Our company was proud to help contribute to these efforts and encourage others to donate as well. If you are interested, please research local food drives, food banks, or other nonprofit organizations in need.

Boiler Basics 101: Economizers for Increased Efficiency

The price of fuel is constantly fluctuating and with it comes creative ways to be more economical. Finding methods to be more energy efficient is never a waste of time. In the boiler room, efficiency improvements can be found by many sources, however, a common option for energy savings includes the use of an economizer. What is an economizer? The economizer is a fabricated assembly of finned tubing that captures waste heat extracted from the boiler’s stack flue gases; the exhaust that leaves the boiler stack (or “flue”).

It’s all about the principle of Heat Transfer. While low temperature water, or feedwater, enters a boiler system, high temperature flue gas exits. An economizer captures heat from the flue gas that would typically go to waste, and utilizes it to preheat the feedwater. By doing this, an economizer is able to increase thermal efficiency by decreasing the energy required to heat the water to steam. This will typically result in a reduction of 1% in fuel cost per 10 degree rise in feedwater temperature. Overall, an economizer can be a major cost savings for boiler owners and will easily provide a quick return on investment.

The economizers’ simple technology and static parts provide longevity and low maintenance, and they are available in multiple designs and configurations. Conventional economizers are cylindrical or rectangular and come in a range of sizes for both firetube and watertube boilers. Rectangular designs are more commonly used for larger industrial watertube boilers, and can be configured for vertical or horizontal gas flows, finned or bare tube design, and other additional options if needed. A condensing economizer can improve waste heat recovery even further by cooling the flue gas below its dew point, reclaiming both sensible heat from the flue gas and latent heat by condensing the flue gas water vapor.

BOILER EFFICIENCY COMPARISON
  Combustion Efficiency at
4% Excess Oxygen
Stack Gas
Temperature
 Boiler  78% to 83% 350F to 355F
 Boiler with Standard Economizer  84% to 86%  250F to 300F
 Boiler with Condensing Economizer  92% to 95%  80F to 150F


When determining whether an economizer is ideal for your boiler equipment, the location of the economizer into stack is important. To ensure the most thermal recovery during the process, you need to make sure the economizer is installed as close to the furnace breach as possible. This will help avoid thermal loss and cooling.

At Nationwide Boiler, we offer our EconoStak economizer as an optional addition (or a standard addition in some cases) on our fleet of watertube rental boilers. The EconoStak consists of the economizer as well as all of the associated piping and structural supports required for very efficient and safe operation. In addition, we are a West Coast representative for E-Tech Heat Recovery Systems, a leading provider of economizers for new, replacement, and retrofit applications.

Contact Nationwide Boiler today to see if an economizer is the right option for you, and be sure to check out our previous Boiler Basics 101 blogs. We review various topics each month, so stay tuned for the next edition!

Air Permitting for Rental Boilers in California

With California having the most stringent emissions requirements in the country, it is important to be well versed on any and all rules and regulations when buying a new boiler or renting a temporary boiler. This is our final installment of the 3-part series on air permit compliance for boilers in California (be sure to check out part 1 and part 2 if you haven’t already).

Nationwide Boiler maintains a fleet of rental units that are sub-9 ppm NOx and pre-permitted for use in the SCAQMD. We take care of the bulk of the permit work saving our customers an exponential amount of time (no waiting for the application to be approved), and we pay for any processing fees. This allows for quick installation and start-up of a temporary boiler, which is extremely valuable in an emergency outage. The only requirement of our customer is the source testing of the equipment, if the source test is due. Most of these pre-permitted boilers require source testing on an annual basis, and the source test must be done at a job site within the county’s jurisdiction.

The SJVAPCD does not allow the pre-permitting of rental boilers, but they do have a program called the Temporary Replacement Emissions Unit (TREU) which can be utilized when a rental is needed  in a pinch. This program contains an application shield provision which allows renters to install a temporary boiler in place of an existing permitted boiler that is down for repairs without having to get a new permit for the rental boiler. In order to qualify for the TREU Program, the rental boiler being installed must have a heat input equal to or less than the unit it is replacing. Plus, it must not have the potential to produce more emissions than the current permit allows. There is a time limitation to this program; the temporary boiler can be on-site for a maximum of 180 days within a 12-month period.

If you are outside of the two territories listed above, don’t fret! Nationwide Boiler can assist with the permitting process as needed. In addition, utilizing a pre-permitted boiler in a location other than the SCAQMD does have its advantages and can help expedite the permitting process.

With our headquarters being located in California, it is important to us that we are up-to-date with emissions regulations throughout the state. And with other areas of the country starting to experience a similar push for emissions reductions, we have the expertise and experience to help. Nationwide Boiler is proud to take the lead in helping customers everywhere understand and comply with current and future air regulation standards.
