Hamworthy Peabody Combustion announces the ECOjet burner, offering ultra-low emissions with little or no flue gas recirculation. Ignition is achieved using the Chentronics high energy direct spark ignitor. This burst mode ignition with flashing indicator allows the operator to observe the ignitor condition during operation. Gas-electric ignitors are also available firing natural gas, propane, coke oven gas, etc.

The Ecojet’s staged gas design provides stable flames, up to 20:1 burner turndown, hot standby, available continuous pilot, and precise furnace warm-up, as well as ultra low NOX on a full range of gaseous fuels (natural gas, propane, refinery gas, landfill gas, off gasses) and low NOX on all liquid fuels (No. 2 through No. 6 fuel oil, ultra-heavy fuels such as pitch and bitumen).

The ECOjet is applicable to package, industrial and utility boilers ranging from single to multi-burner wall-fired, Turbo, and other boiler types and provides NOX levels <30 ppm without FGR and Ultra-Low NOX (<10 ppm) with less FGR than other burners and a lower CO2 footprint.

Burner ramp rates are not limited by speed. The burner does not require complicated control systems, nor does it require special fuel or combustion air filtration or straining. Accommodates capacities to 400 MM Btu/hr.

The Vibralert Model 5550 Mechanical Vibration Switch is designed to provide vibration protection for low to medium-speed machinery. An inertia sensitive mechanism activates a snap-action switch with SPDT output contacts if the vibration exceeds an adjustable setpoint. The 5550 contacts can be used to activate an alarm or initiate equipment shutdown.

The housing is weatherproof with an optional hazardous area rating. Electrical (remote) reset with start-up time delay and a second set of SPDT output contacts to accommodate DPDT needs (for example, separate trip and trip light circuits) are available. For harsh environmental conditions, we offer an epoxy coat option.

Renewable energy sealing system

Trelleborg Sealing Solutions developed a sealing configuration jointly with AVN Energy A/S. This unique configuration is engineered to enhance lubrication and optimize friction characteristics, at the same time preventing any external leakage to meet the requirements of continuous pitch systems.

Click here to enlarge image

The specified solution is an arrangement of seals ranging from O-rings to specialized PTFE-based geometries. The actuator operates in constant movement requiring dynamic criteria from the equipment’s components.

The seals within these hydraulic actuators are integral to the total system. Seals must operate at 3,625 psi/ 250 bars with constant pressure on the rod from behind and differential side loads that control positioning. Wear has to be minimized, and dynamic movement that is continuous in short strokes needs to be facilitated. Temperature resistance is required down to -22 degrees F/ -30 degrees C as standard and to -40 degrees F/ -40 degrees C in the Arctic, with maximum temperature capability of +140 degrees F/+60 degrees C.

The hydraulics are designed for easy exchange of the seal set, which is mounted in a module that can be quickly bolted on and off.

Output sensors

Click here to enlarge image

The IMI Sensors division of PCB Piezotronics has released Series EX64xB7x, a line of loop-powered 4-20 mA output sensors with a 1-inch NPT, 90 degree capped elbow conduit, to meet ATEX and CSA approval requirements for use in hazardous areas. Sensors operate from standard 24V loop power, making them directly compatible with existing PLCs, SCADA, DCS, and Plant Information (PI) systems, for continuous vibration monitoring of overall vibration levels on critical machinery in hazardous area application environments.

Sensors are available with either acceleration or velocity outputs and in various amplitude ranges. Outputs of peak or RMS vibration can be selected, as well as optional temperature or raw vibration outputs. The raw vibration output provides a buffered signal that can be used with vibration data collectors to perform detailed diagnostic analysis when a problem is detected.

Natural gas generator set

Caterpillar Inc. announces a new G3516C 50 Hz high-efficiency natural gas generator set available now with optional air and fuel system controls specifically designed for island mode applications.

The G3516C 50 Hz generator set equipped with an island mode control system generates power independently from the power grid with a high-efficiency, natural gas-fueled engine for commercial and institutional customers who require exceptionally reliable, high-quality electric power.

Click here to enlarge image

Cat natural gas generator sets with the island mode feature tackle the major barriers for distributed generation in stand-alone applications where a utility grid connection is unavailable or the utility grid is not stable. The improved transient capability also supports the use of low-emission gas generator sets in standby power applications.

Driven by an electronically controlled, lean-burn gaseous-fueled reciprocating Cat engine, the G3516C generator set was designed to offer a high power density and excellent fuel efficiency while maintaining tight NOX control. It provides the flexibility to operate on pipeline natural gas with the same Methane Number range as Caterpillar’s current natural gas packages and delivers an ISO electrical efficiency of up to 40.4 percent at 50 Hz – even with the use of two engine-driven water pumps.

The Cat G3516C generator set operates at 50 Hz/1,500 rpm with a continuous rating of 1,944 kVA (1,555 ekW). It has a standard NOX emissions rating of 500mg/NM3 at 50 Hz, with performance of 250mg/NM3 at 50 Hz available through a 54 C separate circuit aftercooler (SCAC) system that can be used with a conventional cooling system arrangement in almost all geographic locations. The G3516C is built on a heavy-duty, diesel-based, bottom-end platform with a top-end design for gas application optimization. It also features an open combustion chamber design capable of operating at pressures as low as 1.5 psi (10.3 kPa).

Standard on the G3516C generator set is a digital microprocessor Gas Engine Control Module, which automatically and precisely regulates ignition, engine governing and air-to-fuel ratio for optimum fuel economy. Its air-to-fuel ratio control monitors charge air density and maintains stringent NOX control under a variety of ambient and load conditions. The G3516C features an individual-cylinder detonation sensing and timing control, with a prechamber-type spark plug design for extended service life without adjustment.

The Cat G3516C generator set is easily tailored to specific applications with a wide selection of Cat SR4B generators and generator set attachments, including oversized generators. Additional features include exhaust options, circuit breakers, alarm and remote annunciator modules, and battery chargers.
