ACOUSTIC STEAM LEAK DETECTION FOR YOUR HRSG — GREENBANK ENERGY’S LA 202 ACOUSTIC LEAK STEAM DETECTOR

Acoustic steam leak detection for your Heat Recovery Steam Generator (HRSG)

The Greenbank LA 202 Acoustic Leak Detection System is the longest standing system of its type available. Since 1974 there have been over three-hundred systems installed worldwide.  The modular, expandable system has been designed to meet virtually every application requirement for performance and economy.

Research has proven that true acoustic measurement of sound level in a confined space is more accurate through a wider band width than indirect piezo measurement. However, to provide the ultimate system flexibility, Greenbank can provide either airborne or structure borne sensors as the application requires.

Damage to steam and water piping systems by corrosion, thermal-mechanical fatigue, or slagging have long affected conventional coal-fired boilers. HRSG designs can be affected by some of these issues as well, causing unscheduled outages and lost revenue.

A well-designed acoustic leak detection system enables operators to continually monitor and trend real-time performance of various systems in the unit and provide early detection of a potential problem. Strategically placed sensors enable operators to safely determine the location of a leak or malfunction and schedule required maintenance based on severity. The modularity of the LA202 system allows for additional points to be added at any time with minimal cost and effort.

Typical Applications:

  • Boiler Tubes
  • Superheater / Reheater
  • Main Headers
  • Waterwalls
  • Attemperators
  • Isolation Valves / Relief Valves
  • Pipeline Flow / No Flow

HEP DYNAMIC CLASSIFIERS

Greenbank Energy Solutions Inc would like to introduce our new product line: HEP Dynamic Classifiers

Featuring:

Improved Fuel and Air Distribution

Today’s stringent environmental regulations, low NOx combustion systems and burners, as well as efficient operation of boilers, demand rigorous control pf the air/coal ratio to each burner from the classifier. The HEP Classifier has the ability to balance the air/coal ratio in each coal pipe served by a classifier, with externally adjustable guide vanes at the outlet to each coal pipe. These guide vanes are designed and positioned to either capture or divert the pulverized coal from entering the outlet. Field experience has demonstrated that individual coal pipes can be balanced with +-2-5% variation.

Improved Particle Size Distribution

The HEP Classifier provides burners with a finer, more evenly ground coal. More precise distribution of the coal particles avoids oversized particles that would otherwise pass, unburned, through the boiler furnace. Better particle distribution also allows the unit to operate at lower excess air levels and allows greater turndown without auxiliary fuel for stabilization. For proper NOx and combustion control, even distribution of the primary air and coal is essential and it is necessary to control the air/coal ratio to each burner.

Increased Boiler Turndown and Fuel Flexibility

Improved particle size distribution, together with more even coal distribution to the burners, produces a more stable flame, reducing the boiler load level where the support fuel must be started. Actual operating experience has shown this to be 10% or more below previous minimum operating levels.

Increased Mill Efficiency

Whether you need additional pulverizer capacity as the result of fuel switching or for a low NOx burner installation, the HEP Classifier can deliver.

Increased Combustion Efficiency

The HEP Classifiers ability to create a finer, more evenly ground coal for the burners, allows optimum combustion efficiency – that means better performance and less unburned carbon in the bottom and fly ash.

Faster Response to Boiler Load Demand

Rotor speed control is provided with a ramp time function that adjusts both the acceleration and de-acceleration of the rotor. This feature creates a temporary difference between the actual rotor speed and the speed demanded by the control system, allowing fast response to boiler load demands.

Installation of the HEP Dynamic Classifier

Custom designed for the specific coal pulverization and burner configurations, HEP Classifiers make retrofit installations easy and economical:

  • Low overall height makes conversion of existing mill easy.
  • HEP Classifiers come “pre-packaged” for quick flange connection to your existing coal pulverizers and coal burner distribution system.
  • Minimal time is required to “re-tune” the boiler and firing system.
  • Standard HEP Classifier configurations are available for all manufactures and types of coal pulverizers.

GESI releases a new product…. On-Line solids MassFlo metering

The mass flow rate of PF in each feed pipe is known to be crucial parameters influencing the operation of pneumatic conveyors, combustion efficiency and atmospheric emissions of the plant. These parameters should ideally be measured and subsequently controlled to achieve fully balanced and optimal PF.

Optimizing Fuel Flow in Pulverized Coal and Biomass-Fired Boilers



EUEC2016
3-5 February 2016, San Diego, California

        Greenbank Energy Solutions, Inc in conjunction with IEA Clean Coal Centre presented the following program at this year's EUEC 2016 show in San Diego. Optimizing Fuel Flow in Pulverized Coal and Biomass Fired Boilers

 

Greenbank Energy's Steve McCaffrey, and IEA Clean Coal Centre's Malgorzata (Maggie) Wiatros-Motyka presented at this year’s Energy, Utility & Environment Conference (EUEC) conference at the San Diego Convention Center. Speaking on Optimizing Fuel Flow in Pulverized Coal and Biomass Fired Boilers.

EUEC is USA’s largest professional networking & educational event of its kind with 2,000 delegates, 400 speakers and 200 exhibits. EUEC facilitates information exchange and fosters cooperation between industry, government, and regulatory stake-holders for the protection of our environment and energy security.

Air Bourne Sensor

Air Borne Sensor

The Greenbank Energy Solutions LA 202 Acoustic Leak Detection System is the longest standing monitoring system of its type available in the world.

Since 1974, there have been over three-hundred systems installed worldwide. The modular, expandable system has been designed to meet virtually every application requirement for performance and economy.

Structure Borne Sensor

Structure Borne Sensor

This time tested and proven Greenbank Energy Solutions product provides detection of boiler tube leaks when they are not detectable by traditional methods. This allows management time to plan a repair strategy and schedule a controlled outage, for tube repairs at a time which is less expensive to the plant.

Operators will benefit from reduced downtime as a direct result of minimizing the degree of damage requiring repair. All of which contribute to greater plant availability, efficiency and reductions in operational costs.

Greenbank Energy Solutions Releases New Product Modification

Limestone VARB

Limestone VARBGreenbank Energy Solutions Inc, in partnership with the University of Nottingham and Greenbank Advanced Instrumentation & Measurement (GAIM) in the UK, have developed a suite of technologies for optimizing the distribution of coal and limestone to the burners at coal fired power stations, and limestone feed to the bed of CFB’s (Circulating Fluidized Bed).

The VARB is a non-intrusive passive device designed to break the material rope, equalize the split of the material at pipe junctions and homogenize material distribution across the pipe, with minimal pressure drop in the pipeline. It is used for a variety of material where metered distribution is required.
