Combustion Systems for Industrial Biomass Boilers

Fixed grate, underfed hearth

Combustion with hearth and a rear grate section with hinged cast steel elements. Ash trays are integrated and there is an optional auto de-ashing with auger.

Fully automatic de-ashing of the combustion unit with ash scraper below grate and ash auger. Completely refractory lined combustion chamber.

Moving stepped grate for moist fuels

Combustion with hydraulically or electro-mechanically operated stepped grate, for combustion of dry fuels with high ash content.

Completely refractory lined and stoichiometrically designed primary and secondary combustion air zones.

Stoichiometrically designed primary and secondary combustion air zones. Alternatively with auger or hydraulic infeed.

Moving stepped grate for wet fuels

Combustion unit with hydraulically or electro-mechanically operated stepped grate, for combustion of wet materials with high ash content.

Fully automatic de-ashing of the combustion unit with ash scraper below grate and ash auger. Completely refractory lined and Stoichiometrically designed primary and secondary combustion air zones.

Alternatively with auger or hydraulic infeed.
