IHEA’s Safety Standards Seminar to Cover
NPFA 86 Revisions
Following the release of a “complete revision” of NFPA 86 Standard for Ovens and Furnaces, IHEA has tailored the technical program of its annual Safety Standards and Codes Seminar to bring oven users up to date on the latest oven safety requirements.

Scheduled for April 30-May 1 at the Omni Hotel in downtown Indianapolis, the seminar addresses how the revised NFPA 86 Standard incorporates NFPA 86C, Standard for Industrial Furnaces Using a Special Processing Atmosphere, and NFPA 86D, Standard for Industrial Furnaces Using Vacuum as an Atmosphere, into one comprehensive standard.

The seminar will cover the requirements for the use of PLCs for burner management systems, which IHEA describes as the most significant change in this edition of the standard. The seminar also will cover other revisions such as:

• Confirmation of the removal of the IRED requirement.
• The change to SSOV(s) for mixing machines.
• Time delays of all types for safety devices.
• Revised allowable voltage for safety devices.
• The clarification of heating chambers under purge requirements.
• The added requirements for the exception regarding SSOVs
  in multiple burner systems for service proven above 1,400°F
  (760°C).
• The enumeration of many examples of applications governed by NFPA 86.

“Attending the IHEA Safety Standards Seminar is the best way to stay on top of the latest safety developments,” Seminar Chairman Ray Ostrowski said. “This year, we will be reviewing all of the 2007 changes to NFPA 86, so I encourage attendance to learn about these changes first-hand. Our expert team of speakers is closely involved with the revisions made to NFPA 86, and this is the best place for someone to learn about the recent updates to the published code.”

The registration fee for the two-day event is $700 for IHEA members and $750 for non-members. Seminar attendees will receive a complete copy of the revised NFPA 86 standard.

When is a Cubic Foot Not a Cubic Foot?   Site Registration Required to View
We all know that in convection ovens and furnaces, air is heated by a burner or electrical elements and then is pushed or pulled over and through the workload by a circulating fan.

How to Select a Pump
Pump design variations give users the ability to select the pump that best suits the application.

Optimizing Flotation Dryer Operation
A flotation dryer must deliver a high quality end product in a cost-efficient fashion without compromising safety. To accomplish this goal, multiple cost and performance criteria must be evaluated before selecting a final design.

Portable Chillers for Plastics Processing
Whether you select an air- or water-cooled design, a portable chiller provides an effective means of cooling your plastics process.

Turning Handheld Computers into Temperature Instruments
Harnessing the power of a personal digital assistant with hardware accessories and software tools allows you to harvest time and temperature data about your products and processes.

Emissions Monitor
Portable GreenLine 6000 can be used for compliance, service and maintenance on boilers, burners, ovens, heaters, kilns and other combustion applications. It includes up to six gas sensors (O₂, CO, NO, NO₂, SO₂, C_XH_Y, H₂S) and has low NO_X and True NO_X (NO and NO₂ ) capabilities. Other features include CO sensor dilution with auto-ranging up to 100,000 ppm; a built-in cooler with automatic water drain, with option to upgrade to Peltier chiller; remote control unit with built-in impact printer; internal data memory to store up to 1,000 tests; and PC software with real-time graphing, reporting and logging.

Pressure-Relief Sensing
Pressure-relief systems include the ATEX-approved, non-invasive and reusable Integral Flo-Tel as standard equipment to provide end-users with immediate indication of device operation. The burst sensor is installed on the vent side of rupture discs and is activated by the operation of the disc itself. During operation, a magnet arcs away from its rest position, removing the magnetic field from the sensor. This causes the sensor to switch to its fail-safe condition of an open circuit and a latched alarm condition is the result. After operation, the rupture disc and magnet are the only parts that need replacing.

Bellows Seal Globe Valve for Steam Service
Model BE3L is suited for steam, hot water and heat transfer fluid applications. The bellows, gland packing and stem seal act as an impermeable barrier between the fluid and environment to provide a zero-leak, triple-seal construction. Features of the compact globe valve include forged steel construction and stainless steel bellows (tested to withstand 10,000 cycles); Stellite hardened surfaces on valve plug and valve seat; and low maintenance operation. It is rated to 710 psig and 752°F (400°C).

Digitally Actuated Control Valve
DigiBoss is designed for modulating control of OEM packaged systems such as heat exchangers and vaporizers. Mounted on a high-capacity, hung-cage-designed control valve, the electric actuator operates with analog signals of 4 to 20 mA, 0 to 10 VDC or Profibus DP. The high-thrust motor provides positive positioning, prevents burnout and permits shutoff up to 750 psi. The control valve is offered in sizes from 2 to 8", for pressures to 1,550 psig and temperatures to 800°F (427°C).

Mechanical Seal
Intended for use with pumps in light hydrocarbon service at low vapor pressure margins, Model QBQ LZ provides high-reliability sealing with low emissions. Optimized for service with hydrocarbons of specific gravity between 0.40 and 0.60, the seal addresses the problem of vaporization by altering the temperature and pressure dynamics on the seal faces. Smooth, low-amplitude wave patterns are laser-machined onto the seal face to create a hydrodynamic effect that changes the pressure profile on the seal faces and reduces friction and contact loads without increasing leakage.

Process Calibrator/Meter for Process Signals
Wahl P32 is designed to simplify maintenance operations and installation of sensors and transmitters using process signals such as 4 to 20 mA or 0 to 10 V. Features include a graphic interface to ease programming and reading as well as an accuracy of 0.015 percent of reading. The emission function can generate simple or cyclic ramps with adjustable high and low levels and rising and falling times and stabilization time. It also can generate steps and fixed values in order to check span and linearity of transmitters, panel meters and recorders.
