Underfeed combustion 180 to 850 kW

Under­feed com­bus­tion

The dor­mant ember bed ensures low pol­lu­tant emis­sions with fluc­tu­at­ing and prob­lem­at­ic fuels, while the com­plete insu­la­tion of the entire boil­er sys­tem and the elab­o­rate wall con­struc­tion of the fir­ing sys­tem ensure min­i­mal heat radi­a­tion from the com­bus­tion cham­ber and thus a high lev­el of effi­cien­cy of the sys­tem. 

The grate design with dou­ble grate (out­er and inner grate) is opti­mised for the fuel. The fuel is burnt out com­plete­ly via the out­er grate of the com­bus­tion cham­ber. The sec­ondary and pri­ma­ry air can be reg­u­lat­ed sep­a­rate­ly. The fuel can be insert­ed either at the rear, right or left of the com­bus­tion cham­ber. Depend­ing on the fuel, the sys­tem can be oper­at­ed ful­ly mod­u­lat­ing from 25 to 100 %.

Con­sis­tent qual­i­ty

A sol­id steel con­struc­tion and the use of high-qual­i­ty brick lin­ing mate­r­i­al guar­an­tee reli­able sys­tem avail­abil­i­ty for many years. Thanks to fre­quen­cy-con­trolled screws, dri­ves and flue gas recir­cu­la­tion, we guar­an­tee the low­est pow­er con­sump­tion in all load states of the sys­tem.

Select­ing the right wood fir­ing sys­tem

In addi­tion to the ener­gy require­ment, the type, lumpi­ness, water and ash con­tent of the fuel are the most impor­tant fac­tors for select­ing the right fir­ing sys­tem. How­ev­er, the annu­al util­i­sa­tion hours and the annu­al dura­tion curve are also impor­tant fac­tors.

The MAWERA sales team will advise you on the choice of a fir­ing sys­tem tai­lored to your needs.
