The main boiler was built as coalfired, which is why pellets were ground in coal pulverizers that were slightly modified for biomass and operated at low temperatures to eliminate the risk of fire. Further modernizations and the addition of a fourth mill enabled that in 2014 the boiler was commissioned for wood pellets [76]. Unfortunately ...

The key differences are listed below. PC firing utilises coal ground to a very fine powder sprayed into the furnace for combustion. CFB uses coal crushed to sizes of around 3 to 6 mm. The time energy and facility required to crush coal is much lesser than pulverizing coal. PC firing uses around 30 % of the combustion air as high pressure ...

A pulverized coalfired boiler is an industrial or utility boiler that generates thermal energy by burning pulverized coal (also known as powdered coal or coal dust since it is as fine as face powder in cosmetic makeup) that is blown into the firebox.. The basic idea of a firing system using pulverised fuel is to use the whole volume of the furnace for the combustion of solid fuels.
