Objective
PROJECT OBJECTIVES
The project involves the development and demonstration of a new instrument suitable for combined measurement of furnace gas conditions in the high temperature zones during biomass combustion. An new improved High Temperature Anemometer (HTA) suitable for accurate measurement of gas velocity and direction will be developed and calibrated against known measuring techniques in a pulverized coal fired test facility and then combined with an oxygen probe and thermocouple to provide accurate simultaneous measurements during operation in a 5 MW grate fired biomass furnace.
TECHNICAL APPROACH
The project consists of three phases, Phase 1 will be to investigate the gas flow and particle tracking across the instrument using computational fluid dynamics (CFD). This will assist in determining the requirements for the instrument head profile and vane wheel angle to provide maximum cooling for higher temperature operation in the harsh environment. Phase 2 will be the manufacture, evaluation and calibration testing of the components which form the fundamental part of the instrument. Based on the CFD analysis several instrument heads and vane wheel geometry's will be manufactured and tested in a 88MW thermally rated test facility in the UK firing pulverized coal. The final arrangement will be selected and calibrated under controlled firing conditions against measurements taken using a Laser Doppler Anemometer (LDA). During this phase consideration will be given to combining the HTA with the oxygen and temperature probes which will be employed during the testing. The final phase of the project is to apply the new instrument in a biomass fired boiler and demonstrate its capability to withstand the harsh operating environment and evaluate its capability and effectiveness in optimizing performance of the firing system during routine boiler operation.
EXPECTED ACHIEVEMENTS AND EXPLOITATION
The new HTA will have a temperature range up to 1300 degrees C and be capable of measuring gas velocities up to 40 m/s in heavily dust laden environments with an accuracy comparable with current more sophisticated techniques. The availability of simpler more practical test equipment will provide a wider scope for combustion diagnostics and encourage further investigations into the combustion of biomass leading to its wider use as a sustainable fuel.
