LAND - Combustion Efficiency and Continuous Emissions Monitoring

LAND is an international designer and manufacturer of flue gas combustion efficiency, environmental emissions monitoring and infrared process thermal imaging instrumentation. Our broad product range includes portable and continuous analysers for CO, O2, NO, NO2, NOx, SO2, CO2, H2S, CxHy, H2O, acid dewpoint, smoke and particulates, plus process thermal imaging. Founded in 1947, LAND is a part of the AMETEK group and has offices throughout the world including in the UK, US, France, Italy, India, Germany and China.

Boiler combustion efficiency monitoring

A range of combustion efficiency monitors includes measurements of flue gas oxygen (O2) and carbon monoxide (CO). These provide primary information for controlling overall boiler efficiency. In addition, acid dewpoint temperature monitors are a reliable, preventive method against plant erosion and damage as a result of burning sulphur-bearing fuels.

• Genesis WDG – range of zirconia sensor flue gas oxygen analysers
• Series 9000 – cross-stack, infrared carbon monoxide monitors
• Lancom 200 – portable sulphuric acid dewpoint temperature monitor
• Model 440 – continuous sulphuric acid dewpoint temperature monitor

Opacity monitors and dust monitors

A range of flue gas dust monitors and opacity monitors gives vital analysis of pollutant particulate emission levels. All the dust monitors use a patented measurement technique for high accuracy and reliability.

• Model 4200 – low cost, cross-stack smoke and particulates monitor
• Model 4500 MkII+ - cross-stack opacity monitor for compliance monitoring, TÜV and MCerts approved
• Model 4500 Premier - 0mg/m³ to 10mg/m³ measurement range dust monitor, TÜV and MCerts approved
• Model 4500 MkIII – our new compact, compliance opacity monitor

Continuous emissions monitoring

The FGA range of continuous emissions monitors are ideal for monitoring of process emissions. Complete flue gas analysis of CO, O2, SO2, CO2, NO, NO2 and Total NOx is essential for both efficient and environmentally acceptable performance. Performance standards certified by TÜV, MCerts and US EPA ensure complete confidence in measurement results. Data acquisition and analysis software systems are also available. Specially designed, bespoke continuous emissions monitoring systems (CEMs) are routinely engineered to meet particular application requirements.

• FGAII – complete emissions monitoring system - CO, O2, NO, NO2, NOx, SO2 and CO2
• ChillerProbe – advanced flue gas sampling system for FGAII
• Unicorn - advanced flue gas sampling system for all FGA analysers
• FGA 900 Series - range of stack emissions monitors for CO, O2, NO, NO2 and NOx

Portable flue gas analysers

The Lancom range of portable gas analysers offer instant analysis of up to nine flue gases including CO, CO2, O2, NO, NO2, SO2, H2S and hydrocarbons. A complete boiler analysis including that of combustion efficiency, excess air, heat loss and environmental emissions can be undertaken. A wide range of probe types, plus other user selectable options are available.

• Lancom III – portable analyser, which is fully configurable to have the required gases and options fitted to meet exact user requirements
• Insight - data acquisition and analysis system for portable analysers

Combustion turbine blade temperature monitoring

Turbine Sentry is a proven, non-contact temperature monitoring system for utility gas turbine rotor blades.

Critical vessel refractory monitoring

When processes take place inside refractory lined vessels it is critical for safe plant operation to ensure the integrity of the refractory lining. In the event of refractory breakdown hot gases come into contact with the vessel shell, potentially causing catastrophic failure and risking costly unplanned shutdowns.

The proven critical vessel monitoring system from LAND is able to provide a significantly improved measurement density with one measurement per 16cm²/0.02ft², allowing earlier detection of refractory breakdown (often before the problem becomes dangerous).
