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.

Minimizing blowdown rate can substantially reduce energy losses
Companies in the market for a new boiler have some choices to consider. One option is to replace boiler with essentially the same unit, adding some additional features to make it more energy efficient. Another option would be to look into implementing a combined heat and power (CHP) strategy which would make the company eligible for a 10% Federal Investment Tax Credit.
Ware develops improved product to answer industry need
The Mod V valve is a newly developed product from Ware that replaces other feed water valves that were not performing as well in the field.
Professionals from Ware noticed an increase in maintenance on certain valves due to leaking problems both at the bonnet and through the valve itself. Lead time for getting replacement valves was also a concern, so the company decided to develop their own valve and the Mod V was born.
“The valves we were using were causing problems on our rental fleet in the field,” explained Brian Grinestaff, Ware parts manager. “The four bolt connection would leak causing increased maintenance, water usage and boiler flooding.”
The Mod V is an improved design. Using a V ported ball valve, the Mod V has great control and a bubble tight shut off to end leakage and cut down on waste. The parts are also readily available to shorten lead times. The new valve is more dependable and can hold up under the industrial use it is intended for in the boiler industry. It is designed for boiler feed water applications and is available in either 0 to 135 ohm or 4-20Ma Signal.
The new valve went from a standard linkage design to a newly designed precision machined linkage, that prevents slippage on the shaft. This change allows for lasting durability as well as increased repeatability and accuracy.
“We have been using it on our rental fleet and have seen a decrease in the maintenance and replacement of these valves,” said Grinestaff. “The Mod V is also available for all of our customers and we have recently been able to replace faulty valves in less then 2 days.”

Fluid Engineering has added a new design to its product
line. The Model 545 is an in-line duplex liquid
strainer (patent pending) to improve the liquid flow
and save cost in the piping process.
Both sides of the duplex are designed for 100%
process flow and new geometry offers a lower
differential pressure, measured from the inlet flange
to outlet flange. This allows operators to transfer the
flow to the other side of the unit to clean the filter
basket when high differential pressure is observed.
The 545 is also available in an automated design: One side is in process and when the differential
pressure reaches a set point, it sends a signal to the control panel which in turn signals the clean side
valves to open. Once the clean side is open the dirty side valves close and a drain valve opens. At
this point the control panel will send a signal to the main control system alerting the operator that
maintenance is needed to clean the filter basket. If there is no main control panel, the operating
panel can be fitted with either a flashing light or siren. Once maintenance has been performed on
the basket and the closure tightened, a push button on the panel resets all of the functions and the
panel is set for the next high differential pressure.
