The theme of the 2015 Conference is Clean Campus Energy for the Next Generation
We are very excited that GEA Heat Exchangers will have a booth at this Conference!
Stop by to say hello to Karl Johnson of Pentad and meet Shane Bixby of GEA.
The Conference is February 10th to 13th, 2015 and is being held at the Sheraton Denver Downtown.
The Newsletter starts with a letter to GEA PHE’s friends and bussiness partners, then overviews the first US order for the GEAFlex. After that, GEA gives credit to Thermoflo for selling nine NW350 Fermenter Coolers! Next, GEA tells about new Double Wall Units installed in Texas! Lastly, the newsletter gives the names and dates of upcoming tradeshows that they will be attending!

Ware’s recent newsletter gives their readers a tip to save thousands of dollars!
A boiler cycle includes a firing interval, a post-purge, an idle period, a pre-purge and a return to firing. Boiler short cycling takes place when an oversized boiler quickly fulfills process or space heating demands and then shuts down until heat is required again.
Boiler efficiency can be calculated over the cycle duration by taking the useful heat provided by the boiler and dividing it by the useful heat plus losses. Boiler efficiency is reduced when short cycling occurs or when several boilers are operating at low firing rates.
[MORE]
Boilers can be too large for the required processes for several reasons. It could be that process heating demands fluctuate over time or additional capacity was added to restart a facility quickly after being closed overnight. Boilers may have been installed based on plans for additions and expansions to a facility that never happened. In addition, concessions may not have been made for heat contributions from other sources such as lights and equipment.
If a facility has installed energy conservation or is employing heat recovery methods, the heat demand can be reduced and therefore a facility could have multiple boilers operating at several times the maximum expected capacity.
Suggestions:
Determine the efficiency and operating cost of each boiler
Adopt a control strategy for maximizing boiler operations
Avoid short cycling by purchasing a burner with a high turndown ratio or by adding a small boiler to the boilerhouse to provide better flexibility and high efficiency at all loads

Just like the engine in your car, boilers have need of a certain fuel-to-air ratio for proper
combustion. Too little air results in incomplete combustion, but too much creates wastefully heated air
that gets exhausted through the flue. Since changing factors such as ambient temperature, pressure,
and humidity can cause variations in air quality, it is prudent to add an excess amount of air to account
for these variations. To add the proper amount of air to mix with the fuel, controls are used to introduce
air to the system at the burner. Of the boilers currently in use in the United States, many older models
utilize a simple control called a mechanical jackshaft for their modulating burner control. These are also
known as single-point controls due to their use of only one mechanical linkage assembly to control the
flow of both air and fuel for the burner.
The whole point of utilizing these controls is to ðÌðtuneðÌð the boiler in order to achieve complete
combustion. With that in mind, anything that prevents mechanical controls from operating to their full
range limits the amount of air that can enter the burner, thereby jeopardizing the combustion and
efficiency of the boiler. One of the most common mistakes made that impairs the controls is painting
the linkage or failing to keep it clean; this leads to what is known as ðÌðsloppy linkage.ðÌð Paint or grime
covering the linkage will prevent the controls from allowing fine adjustments, hindering an operatorðÌðs
ability to regulate the air being added. During the inefficient operation that inevitably results, expensive
fuel can be wasted, and the rated steam output of the boiler is harder to deliver.
There are also significant long-term consequences to sloppy linkage; for example, depending on
how filthy or covered the linkage is, the valves can eventually stick or bind, which is going to require
otherwise unnecessary maintenance to repair. If the valves are out of position and air is improperly
mixed with fuel, excess soot may build up in the boiler and flue, which may necessitate a premature
shutdown of the system for cleaning or repair. WareðÌðs own Gary Seltz notes that ðÌðone of the most
common issues we see is bent linkage that people have accidentally kicked.ðÌð Care should be taken
around the jackshaft, as not all equipment in a boiler room is as robust as the boiler itself. It is estimated
that damaged linkage can be replaced in about four hours, so depending on when that changeover must
be performed, it could mean more downtime and less steam generation for your company.
When a boiler is not being operated properly, you may be liable for any repairs due to
negligence. By taking some simple steps to ensure that equipment is properly maintained, you can avoid
costly and time-consuming repairs. It is recommended that the controls be checked at least twice per
year (though quarterly would be ideal) to see if seasonal adjustment or tuning is needed. Make no
mistake, linkage can be marked upon, but fully covering the assembly with paint or allowing it to get
filthy only serves to create long-term problems that are easily avoidable. Maintaining efficiency with
your boiler prolongs its life, avoids down-time for repairs, and reduces operation and maintenance
costs. So remember: keep your linkage cleanðÌðitðÌðs easy and will save time and money!

Webster Combustion has announced that dates have been set for their 2015 Combustion College. The JB or beginner class is on April 13th, 14th and 1/2 day on the 15th. Webster will cover combustion, burner set-up, linkage controls and troubleshooting control panels.
The HD or advanced school is on April 16th, 17th and 1/2 day on the 18th. Webster will cover low NOx applications, linkageless controls, high turndown and larger burners. Webster expects attendees to have already had some start-up experience before attending this advanced class. Both schools are a combination of class room and lab work.
Classes will be offered with Autoflame, Siemens, Honeywell, and Fireye. These classes will be held on April the 17th. The classes will be two hours in the morning, 1 hr in the afternoon. For HD applicants, please designate on your application morning and afternoon choices for these classes.
The cost of each training class is $1100 for a single room, and $1000 (each) for a double room. This will include the 2-1/2 days of Service School, hotel, and all meals. Webster will provide transportation to and from the Wichita Airport to the hotel and factory.
The week following Webster Service School, Siemens will conduct a service school there. Date and times are all day April 20th and 1/2 day the 21st. This training is being offered to Start-up and Operations people and is being instructed by the Siemens Service Group.
For people enrolled in Webster Service School the Siemens class is free with the exception of your hotel and meals.
For Non-Webster School Enrollees the price is $150 for the complete class plus hotel and meals.
Webster will provide transportation to and from the Wichita Airport.
