Get A QuoteA lignocellulose biomass when roasted in an oxygen free environment at temperatures higher than 250°C loses parts of its mass in volatiles. The solid fraction that is rich in carbon is called torrefied biomass or "biocoal". Biocoal represents a renewable energy commodity that can substitute for coal. Pelletization improves the handling of a low density torrefied biomass. The common

Biomass and sewage sludge fuels usually contain a lower amount of fixed carbon and a higher percentage of volatile
Get A Quote2013-6-5 · The boiler for raising steam is positioned above this second combustion chamber so that it can absorb the heat generated during combus tion. The heat warms, and eventually boils water in the boiler tubes, providing steam to drive a steam turbine. From the steam turbine the steam is condensed and then returned to the boiler so that it can be cycled through the system again.
Get A QuoteThe efficient combustion system of the boiler combined with the very efficient flue gas cleaning system of the plant guarantees a minimised impact on the environment. The substitution of part of the coal by biomass reduces CO2 emission from fossil fuels, too.
