SolaGen Inc.  is a design, engineering, and manufacturing firm specializing in customized, leading edge wood combustion technology. Combustion systems are designed for 24/7 operation in commercial and industrial heating applications, utilizing a range of fuel inputs including wet or green wood chips, wood pellets, or dry wood dust. Components are industrial quality for heavy load environments, continuous operation, and remarkable longevity. The equipment blends modern combustion technology with proven quality and reliability, built in the USA. Package heating systems include bulk storage, fuel handling, emissions controls, engineered solutions to fit any customer request.

SolaGen HDF-WC Pellet Stokers Maine Woods Pellet, 500,000 Btu Pellet Stoker

Designed and built for severe duty use, efficiency, and low cost of ownership. The unique burner design incorporates a gun style, water-cooled burner mounted to a refractory lined firebox and three pass heat exchanger (boiler). Combustion air is preheated for maximum cycle efficiency and delivered to the combustor via forced and induced draft fans. The SolaGen HDF-WC boiler and stoker package is a two stage combustor, or “close-coupled” gasification boiler. This package system is control through a PLC based logic controller with a web enabled, touch screen user interface.

Size Range: 500,000 – 3,500,000 BTU (145-1025 kW)

Wet and Green Wood Chip Boiler Systems

SolaGen Inc. offers a wet wood burner with a cast-chrome grate underfeed stoker for combustion of high moisture fuels (20-45% m.c.). This burner type is ideal for the selected fuel type, maximizing the effects of in-pile water evaporation, leading to high combustion temperatures while minimizing emissions. Additionally, SolaGen offers the full solution for wood chip storage and handling equipment to meet any customer specific needs. Fuel handling systems are designed to minimize operator involvement and material flow interruptions. It is typical for large installations to include one or two high efficiency multi-cyclones, baghouse, or ESP for emissions cleanup.

Size Range: 500,000 – 10,000,000 BTU (145-3000 kW)
