Boiler Efficiency Testing

Operating a boiler that is not optimised, or tuned, can result in one or more problems including:


Fallout of pulverised fuel, blocked pipes, or high mill pressure.

Erosion of mill, pipes and burner components.

Poor burner ignition, and flame instability and dislocation.

Incorrect primary and secondary air-to-fuel ratios.

Increased nitrous oxide production.

Increased levels of unburnt carbon.

Increased excess-air requirements.

Increased erosion between furnace and boiler exit.

Reduced boiler efficiency.

Localised furnace problems that can include inappropriate superheater and reheater temperature profiles, increased slagging and greater water-wall wastage.


Solution

Inthuu provides boiler efficiency testing to enable plant operators to understand their potential to improve boiler performance and availability, and reduce the maintenance. Testing may involve different plant including pulverisers, classifiers, fuel splitters, air-supply systems, burners, furnaces and complete boilers. Inthuu can undertake tuning where existing plant infrastructure can be adjusted to improve performance.

Inthuu Measurements can help optimise proposed plant modifications, or in developing additional infrastructure to improve the performance of plant components.

Inthuu Measurement draws on its expert modelling capabilities when undertaking system design and in developing custom solutions.

Inthuu works closely with clients to provide services or design work to meet budget and capital expectations, and to provide incremental improvement.
