CFD based identification of clinker formation regions in

To validate the modelling based identification of clinker formation zones, three clinker deposits in the vicinity of burners (burners 12, 43 and 53) in a local large scale boiler are collected to arrive at the clinker formation temperatures. The details of clinker deposits are reported in Table 8. The samples were examined using a combination

Getting the best out of your biomass boiler | AMP Clean Energy

Beware of clinker! Severe ash can build into clinker, which looks like pieces of crystallised ash. Clinker formation is the most significant factor in wood pellet fuel quality and can stop your boiler working. The key factors are the melting temperature of ash residues and the percentage of ash in the fuel.

Therefore helps in reducing the boiler maintenance, provide ease in cleaning and increases the boiler availability for long term operation. It promotes smoke free combustion, resulting in improved fuel economy.

Coal Ash Clinkers!!! | Stoker Coal Boilers Using

Sometimes burning it HOT for extended periods (when it's really cold which it has been with a good draft) will cause more clinkers. I had that problem with one of my stoves before I put a baro on it, it was burning way too hot to keep up and formed and ash bridge/clinker, clogged up and made a real mess..I know the EFM's are a bit different stoker, but it happens in regular stoves too.

Typical Causes of Slagging and Fouling Problems in Boilers

The No. 1 cause of furnace slagging is low furnace oxygen content. Most boilers are designed for 115% to 120% theoretical combustion air. This is generally expressed as 15% to 20% excess air.

Fuel impurities can lead to slag formation in the boiler furnace, and leave clinkers on fuel beds, while the presence of sulphur can lead to the cold end corrosion. Impurities in fuels and operational problems limit maximum output from burned fuel. It is possible to improve the fuel combustion and reduce un-burnt carbon in the ash.
