The end of the year is approaching quickly, which means Nationwide Boiler is gearing up for the 24th annual Power-Gen International Tradeshow & Conference, December 11-13, 2012. This year the show will take place in Orlando, FL at the Orange County Convention Center, and will include exhibitors from over 1,200 companies around the world showcasing their products and services catered towards the power generation industry.

Come join Nationwide Boiler at booth #5219 where we will be promoting our stock of new and reconditioned low NOx boilers for rent and sale, as well as our  CataStak™ SCR system to reduce NOx levels for compliance of strict air quality regulations.

For almost a decade boiler manufactures and operators have been waiting for the federal government to determine what must be done to meet stricter emission standards for toxic air pollutants.  As published recently by Power Engineering, industry officials now say the new standards won’t be unveiled until November to December and the EPA’s revised Boiler MACT rule remains under review by the Office of Budget Management’s regulatory affairs division.

The final rule establishes national emissions standards for hazardous air pollutants (Mercury, PM, hydrogen chloride and carbon monoxide) for industrial, commercial and institutional boilers.  It applies to major sources that emit 10 or more tons a year of any single pollutant of 25 tons or more a year of any combination.  It will also require annual boiler tune-ups in some instances.  In total, the EPA estimates the cost of adding new controls will exceed $5 billion and some sources indicated that it would force power producers to retire about 4.7 GW of coal-fired capacity, due to high compliance costs.

Once the revised rule is finalized, boilers owners and operators will have three years to comply.  This is in addition to other existing clean-air rules the industry has to comply with.  However, despite the unique challenges the industry may face, boiler manufactures and associated suppliers are ready to tackle future compliance challenges.  Overall, the boiler industry has the technology and know-how available to provide immediate solutions.

“We can only hope that OMB is doing more toward achieving compromises and consensus than just sitting on its hands for political purposes,” explains Randy Rawson, ABMA President and CEO.

Three new ultra low NOx (ULN) mobile boiler rooms have been added to Nationwide Boiler Inc’s growing fleet of rental boiler systems.  The boilers have been specifically designed, manufactured and assembled to meet the increasing demand of steam for commercial and industrial boiler users located in California and other parts of the nation who must comply with strict air emission requirements. All three units have been pre-certified to comply with permitting agencies including the South Coast Air Quality Management District (SCAQMD) and the Bay Area Air Quality Management District (BAAQMD).NBI Mobile Boiler Rooms

The three new units include a pair of 47.5 hp (200 psig) ULN boilers enclosed in 27’ single axle vans and one 650 hp (250 psig) ULN boiler enclosed in a 53’ van.  All boilers include 9 ppm gas-fired burners (with the option to fire propane fuel), deaerators, feedwater pumps, chemical treatment systems, blowdown separators and sample cooler stations.

For more information about these boiler systems and other units in our rental fleet, visit our website at www.nationwideboiler.com.

No matter what type or size of boiler you are looking to purchase, there is always one question you must always answer when selecting a steam boiler: What is the basis for design?  Fulton Company recently published a list of 10 features you wish every boiler had.   It is important to review this list and be sure to know which attributes are most important to you and your specific application.  In addition, when selecting the right boiler provider, remember that any qualified boiler company should be able to provide you with accurate boiler specifications, performance data, and drawings, all of which will make the decision process easier and will help you along the boiler decision process.

*** With emission requirements changing everyday, it is also important to make sure that you are proactive when selecting equipment that will comply with future air regulations.  Nationwide Boiler has the most experience in selecting boiler equipment that will meet current and future NOx requirements and we developed the CataStak SCR system as a solution for ULN compliance.  Contact Nationwide Boiler today to discuss the requirements of your new or used boiler systems.  We will be happy to help.

1. High Pressure Vessel Mass

The mass of the boiler will be a good indication of the amount of metal used to manufacture the pressure vessel. Mass is related to thickness and thickness is related to durability. Inherently, low mass boilers will not last as long as high mass boilers.

2. High Water Volume

Water under pressure will store steam. Higher water volume means higher stored steam. Applications where you have rapid swing loads will require a high water volume boiler design.

3. High Efficiency

We all would like to have the most efficient boiler. Efficiency, however, must be defined and compared on equal terms. Ensure boiler pressure, feed water temperature, firing rate, fuel BTU value and stack CO2 levels are all defined on the same playing field.

4. Quick Startup Times

Simply put, you want steam in a reasonable time frame. Boilers that can make steam quickly likely will have low water and low mass, which may be non-desirable features. One must also realize a quick startup will facilitate a quicker cool down. The boilers on the market today typically require 5 to 20 minutes startup time or more, depending on the size of the boiler

5. Low Footprint

Boiler room real estate is quite valuable these days and the less room a boiler occupies, the better. Be sure you take into consideration the amount of room required to perform maintenance on the boiler as part of the overall footprint.

6. Low Heat Flux and High Heating Surface Area

Heat transfer is represented by the equation

Q =m x Cp x ΔT

where m is the heating surface area.

Most heating surface area listings are for the fire-side surface area, with higher fire-side surface area values indicating higher the heat transfer efficiency. However, one also must consider the wetted heating surface area. The wetted heating surface area determines heat flux. Consequently, low wetted heating surface area can have very high heat flux, which can create higher metal temperature and increase scaling potential.

Boilers with high fire-side and high wetted heating surface areas will be the most efficient and have low heat flux.

7. Ease of Clean Out

This is a measure of effectiveness of blow down and ability to keep the pressure vessel clean.

8. Effective Turndown

This feature has a lot to do with the burner performance. Effective turndown is a measure of how low the fuel input and air can be adjusted to maintain good combustion efficiency. Some burners will turn down the fuel but leave high excess air on low fire. This will create high turndown but poor overall combustion efficiency. Look at the highest turndown level while still maintaining good combustion efficiency.

9. Ease of Maintenance

Hardly ever will a specifying engineer think about maintenance when selecting a boiler. They should. Blow down valves, stack location, feed water inlet, control panel location, tube removal, burner removal and gas piping maintenance should all be considered as criteria of boiler selection.

10. Large Steam Disengagement Area

Like heating surface area, the more steam disengagement area, the better. Higher steam disengagement area produces higher steam quality, especially for low pressure steam applications. Consequently, horizontal boilers generally will produce higher steam quality than a vertical boiler of the same output.
