Maximize Electric Heater Performance

Ten Tips to Maximize Heater Performance


Electric Heating elements are very durable and can last a png time with some preventative care for the elements. In the industrial world some heaters are put ito abusive environments so using some of these tis could add life to your electrical heating elements and heaters. 

Contact Anderson-Bolds HERE!


Watlow Firebar Elements

















Many plant engineers do not give much thought to the heaters operating within their processes and applications - unless those heaters fail, require significant maintenance or cause other problems. Unfortunately, heaters play an integral role in many applications. Therefore, heater problems can easily snowball and lead to much larger headaches.

Following a few simple guidelines will not only reduce the likelihood of heater-related issues, but can actually have a significant positive impact on the efficiency of systems and reduce maintenance requirements and costs. Below are 10 ways to maximize a heater's service life and performance.

Tip 1: Guard against heater contamination

Contamination is the most frequent cause of heater failure (see images). As heaters expand and contract during cycling, they often draw in organic or conductive materials. This can lead to an arcing failure between individual heater windings or between heater windings and the electrically grounded outer heater sheath. When allowed to collect at the lead end of a heater, contaminants can also cause electrical shorts between power pins or terminals. Therefore, it is important to keep lubricants, oils, low-temperature tapes or processing materials out of contact with the lead end of the heater. Employing seals will help.

Tip 2: Protect leads and terminations from high temperatures and excessive movement

Standard fiberglass-insulated lead wire may be used in applications with ambient temperatures up to approximately 260°C (500°F). If a lead is exposed to higher temperatures, high-temperature lead wire or ceramic bead insulation should be used. An unheated section of the heater, extending away from the heated region of the system, enables the leads to run at a beneficially cooler temperature.
When heaters are mounted in moving machinery, it is essential to anchor the leads to prevent them from being damaged. A lead protection option should be specified and used for optimum protection against lead damage.

Tip 3: Heater selection and sizing are important

A heater's wattage should be matched as closely as possible to the application's actual load requirements to limit ON/OFF cycling (see tip 6). For fitted-part applications, specify the hole or an alternative application feature size to ensure an optimal fit between the heater and application feature. A tight fit minimizes air gaps and reduces the instances of hot spotting.

Tip 4: Ground the equipment

It is common sense and safe practice to electrically ground all equipment on which the heater is used. Grounding equipment helps protects plant and personnel in the event of an electrical failure in the heating system.

Tip 5: Regulating voltage ensures the rated heater voltage matches voltage supply

It is essential to ensure a heater's rated voltage matches the available voltage supply because wattage increases (or decreases) at the square of the change in voltage applied to a heater. For example, if a heater is rated for 120V/1000W and is connected to a 240V supply, it will generate four times the rated wattage output or 4000W. This will cause a heater to fail relatively quickly and can also cause significant damage the attached equipment.

Tip 6: Prevent excessive heater cycling

Excessive temperature cycling is very detrimental to the life of a heater. The most detrimental is the cycle rate that allows full expansion and contraction of the heater resistance wire at a high rate (30 to 60 seconds' power ON and power OFF). This causes severe stress and oxidation of the resistance wires inside a heater. A bad temperature cycle is typically found when thermostats are used. Thermostats respond slowly to temperature changes and have large switch ON/OFF temperature differentials. An improvement, but a somewhat more expensive solution, is to use ON/OFF or PID controllers with mechanical relays. It is crucial to not switch the frequency or cycle time too rapidly (somewhere between 3 to 10 seconds), because the relay contacts can wear out quickly.
The most effective way to minimize heater element temperature cycling, and the most expensive solution, is to use solid state relays (SSRs) and SCR power controllers coupled to PID temperature controllers. This combination provides the best performance for both your thermal system as well as for the heater itself. Solid state switching devices cycle power to the heater very rapidly (from one second with a SSR, down to milliseconds with phase-angle fired SCRs). This fast-power cycling dramatically reduces heater element wire temperature excursions and substantially extends heater life.

Tip 7: Ensure that the sheath material and watt density ratings are compatible with the material being heated

This is absolutely critical to ensure long heater life and healthy processing equipment. When heating solids, such as metals, the operating temperature and heater-to-part fit drive sheath material and watt density choices. Carbon steels, aluminum, silicone rubber sheath materials are fine for lower temperatures (a few hundred degrees). However, as temperatures increase beyond this point, sheath material choices become limited to galvanized or stainless steels and other higher temperature metal alloys. As temperature also increases, the watt density must decrease accordingly to prevent internal resistance wires from oxidizing quickly and failing prematurely. A good heater-to-part fit ensures proper heat transfer and does not force the resistance wires to overheat.

When heating gases, the operating temperature and flow rates dictate what sheath material and watt density can be used. For example, you can run higher watt densities when heating hydrogen versus nitrogen, but hydrogen requires Alloy 800 sheaths, whereas 304 Stainless Steel will work for many nitrogen applications.
Increasing flow and turbulence across the heater elements means better heat transfer, which raises watt density values. For liquid heating, the prime driver for materials and watt density selection is the fluid material and flow rate. Water can easily handle 42.52 to 70.87W/cm2 (60 to 100W/in2) using a copper sheath, whereas a 50/50-water/glycol mix can only handle 21.26 W/cm2 (30 W/in2) and must use a steel sheath.

Tip 8: Mount immersion tank heaters horizontally near the tank bottom

Heaters should be placed horizontally and near tank bottoms to maximize convective circulation. Vertical mounting is only advisable when limitations, such as space restrictions, prohibit horizontal placement. Regardless of whether a heater is mounted horizontally or vertically, it is essential to place it high enough to avoid any sludge and debris buildup in the bottom of the tank. Likewise, for both mounting methods, the entire heated length of the heater must be immersed at all times - one reason vertical mounting is rarely recommended. It is also important to avoid placing heaters in restricted spaces that limit convective flow and/or where free boiling or steam traps can occur.

Tip 9: Prevent build-up and sludge on the heater elements

Scale, coking and sludge build-up on heater sheaths must be minimized. Any accumulation should be periodically removed or at least minimized, to avoid inhibiting heat transfer to the liquid. Periodic cleaning prevents heater elements being forced to operate at higher temperatures, which can lead to early heater failure. Extreme care should also be taken to avoid getting silicone lubricant on the heated section of a heater. Silicone will prevent the "wetting" of the sheath by the liquid, act as an insulator, and possibly cause the heater to fail.

Tip 10: Ensure proper, tight temperature control and safety limit protection

Matching the appropriate temperature control system to the heater is imperative to strong heater performance and life. Each process application should, at the very least, include a process temperature sensor (to sense the material being heated) and a limit sensor (to sense the heater sheath temperature). The process sensor should be directly immersed into the material to be heated, or snugly inserted into a thermowell inside the fluid itself. For safety reasons, two separate control systems should be used - one for process temperature control and one for high limit control. PID type process temperature controllers offer more stable control and faster response than ON/OFF switching controls or thermostats. The trade off is that PID control is often more expensive than ON/OFF types and not always necessary for applications that do not require highly accurate temperature control.

Process Ovens Over 40 years Old


Safety Updates for Older Ovens.

 

Most Process ovens made over 40 years ago did not include an excess temperature controller or separate heating element contactors to protect the oven from overheating if the main temperature controller or contactors fail. 
 Any ovens like this should not be used until this safety equipment is installed.  Failure to install this safety equipment could result in the oven overheating and a fire that could result in oven damage, loss of the product load, building damage and injury to personnel.
 

A field kit to add the excess temperature controller and separate contractors should be ordered from the MFG.

The excess temperature controller and separate contactors are now standard equipment on all Grieve ovens.  Also standard is a recirculating blower airflow safety switch to shut down the oven heat if the recirculating blower fails.  This is a pressure differential switch that senses the pressure created when the blower wheel is turning.  This switch protects the oven heating elements by preventing them from heating when air is not being recirculated over them.  A field kit for installation of the recirculating blower airflow safety switch should be purchased from the oven MFG.


When installing new safety equipment it can be a good idea to add other new electronics to the oven for better performance.  New electronics could be a digital temperature controller, programmable digital temperature controller, new thermocouples or a digital timer.  Grieve can provide a field kit to add a digital temperature controllers as well as and a field kit for a digital shut down timer. For electric Ovens new elements can be ordered as well along with pin and sleeve disconnect switches for added electrical safety for personnel. We can provide Gas meters for gas ovens to measure gas flow at the oven and shut the oven down in a dangerous situation.

Grieve's field kits include installation instructions, wiring diagram showing items to be removed, wiring diagram showing items to be added and revised wiring diagram for your records.  Our kits will be based on how the ovens were constructed when they left our factory.  If there have been changes made to the oven in the field they will not be included in our revised wiring diagram.   


Grieve will provide all parts except for standard wire, conduit and conduit fittings.  These items are better provided in the field as necessary to connect the components being added.  Conduit would only be required for the air flow safety switch as the other items are mounted in the oven control panel.

Please contact Anderson-Bolds with the oven serial number, job # and model number all of which can be found on the name plate of the oven.  We can also provide new wiring schematics for old ovens and instruction manuals.  Grieve and Anderson-Bolds want our products to be operated in the safest manner possible.
