Solid Fuel Boilers Biomass Direct-Fired Energy Systems (Hot Gas Generators)

SCS supplies a full line of biomass fired energy systems to generate hot gas for the wood pellet and wood products industry.



The SCS biomass direct-fired energy systems have outputs up to 300MMbtu/hr and utilize reciprocating grate combustion technology, which is the preferred method for rotary drying systems.

SCS is capable of providing a completely customized design, including fuel storage and handling, reciprocating grates, refractory lined furnaces and ductwork, and automatic ash handling equipment. SCS can offer equipment only or turn-key installation and aftermarket services depending on customer requirements. Optional waste heat steam boilers can be supplied to generate conditioning steam for the industrial process. In the engineered wood products industry, thermal oil heaters can be added to this system to provide hot oil for use in the log conditioning ponds, building heat, and/or continuous and multi-opening presses.
