VOLFRAM offers high efficient 3 pass internal furnace packaged solid fuel fired steam boilers.

Capable of being fired on Wood/Solid agro waste, Coal this is capable of achieving high thermal and combustion efficiencies through the optimum sizing of steam output.

Utilizing the 3 pass wet back concept the full combustion of fuel takes place within the large furnace before passing into the fully submerged wet back reversal chamber. Two passes of convection tubes then carry the hot flue gases through the two convection tube bank in the boiler and thus ensuring complete transfer of heat for steam generation and thus ensuring high efficiency.
