Acoustic Pyrometer is a boiler gas temperature measurement system.

The SEI BOILERWATCH MMP II-SSX acoustic pyrometer is an advanced industrial instrument that provides fully automatic measurement of high combustion gas temperatures, permitting fuel trimming control within heaters & boilers. These systems are available in a variety of configurations and are easy to install, commission and operate.

SEI’s Acoustic Pyrometer, Online Continuous Gas Temperatures Measurement at Flue Gas Exit planes and other sections of the combustion chamber.  A true device that can improve combustion efficiency and optimize boiler and heater operations resulting in low maintenance, increased up time, extended service life and efficient and money saving performance. The results of these operational improvements also reduce NOx emissions, increase efficiency, reduce local slagging, fouling and corrosion, reduce localized hot spots and reduce carbon-in-ash post combustion.

Acoustic Pyrometer Market: Introduction

  • The acoustic pyrometer is an advanced instrument that provides fully automatic measurement of high combustion-gas temperatures and permits fuel trimming control within heaters & boilers. Advancements in instrument help drive the acoustic pyrometer market.
  • Acoustic pyrometer is a non-contact measurement device that obtains highly accurate instant gas temperature data from any location within a boiler.
  • The acoustic pyrometer system helps boiler operators to reduce slagging by maintaining optimal furnace exit gas temperatures
  • It also helps manage critical temperature profiles to aid in emissions reduction, as well as reduce tube damage or leaks by preventing hot spots and thermal shock
  • In addition to temperature measurement, the acoustic pyrometer can be used for leak detection in the area of a boiler which is being monitored for temperature and constantly listens to boiler noises in order to measure preset noise thresholds and time durations, and identifies persistent sounds indicative of leaks. This helps to fuel the demand for acoustic pyrometer.

Rising Demand for Acoustic Pyrometer in Power Plant Applications

  • Based on application, the market can be segmented into power plant, boilers, refineries and petrochemicals
  • The power plant segment is estimated to expand at a rapid pace during the forecast period due to the increasing use of acoustic pyrometer for measurement of high combustion gas temperatures
  • Acoustic pyrometer offers numerous benefits such as real-time temperature data, which helps control and optimize operation, offers better process control, improves product quality, minimizes regrind, and helps reduce emissions and NOx generation. These factors also boost the adoption of acoustic pyrometer.
  • The acoustic pyrometer is best suited for high temperature and dusty conditions, and monitor on-line of the distribution of temperature field in boiler furnace, which is vital to reduce emissions that cause pollution and damages to environment in the power plants. This boosts the demand for acoustic pyrometers in power plant applications.
  • Increasing usage of acoustic pyrometer can improve combustion efficiency and optimize boiler and heaters operations, which results into low maintenance, increased up time, extended service life with efficient performance. This, in turn, is propelling the acoustic pyrometer market.

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

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


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.
