These systems employ a unique patented two-stage, close-coupled gasification technology. First, feedstocks are transported into a refractory-lined gasification chamber featuring a deep fuel bed that allows for a quick response to changes in demand. Here, feedstock is roasted and pyrolysis gas is released into an oxygen deprived environment. Next, this gas is released through a burner nozzle and combined with oxygen for combustion at temperatures exceeding 2,100˚ F. These high oxidation temperatures maximize system efficiency and virtually eliminate waste byproducts such as ash, creosote and stack effluent. More importantly, virtually all volatile hydrocarbons found in biomass are destroyed, minimizing harmful emissions. This makes these systems safe for any facility and explains why they easily pass the EPA’s most stringent clean air regulations.
The Advantages of Keeping It Cool
Our systems operate at far cooler temperatures than others, producing pyrolysis gas at 1,000˚ - 1,400˚ F, which is well below ash fusion temperatures. This enables these systems to accommodate a broader spectrum of low value biomass fuels with moisture content up to 55%. Lower temperatures also eliminate the potential for mineral fusion within the system, a troublesome occurrence with other gasifiers that results in system downtime and labor intensive grate maintenance.
Automated Operations and Controls, Accessible from Anywhere
These gasifiers feature fully automated fuel storage and delivery systems, and computerized system controls – minimizing labor costs. Intuitive touchscreen control panels utilize Programmable Logic Control (PLC) programming and trouble-shooting is conducted by in-house technicians. Controls can also be conveniently accessed remotely from anywhere in the world, via the Internet.
Scalable and Adaptable Systems to Suit Your Application
Our variable biomass gasifiers provide a turndown capacity of 10:1 or better, and are offered in a range of scales to match your application. Whether you operate a school or university, a municipality, or a large-scale agricultural or industrial operation, with system outputs from 1.5 to 60 MMBTU/hr, there’s a system to fit your needs. Plus, they are designed to adapt easily to the widest variety of heat exchangers and uses, including hot air furnaces, hot oil systems, and hot water and steam systems generating up to 900 psig superheated. Systems are also easily retrofit to existing boilers.

ROI CHART
Compare oil burning to biomass gasification with this system. Annually, a plant can replace 1.0 million gallons of oil with 22,000 tons of biomass by using a variable biomass gasifier designed for <29 MMBTU/hr and realize an annual fuel savings of $2.12 million. This savings pays back the cost of the system in just 9 months and the cost of the complete building project in 5.2 years. More dramatically, over the 25 year minimum expected lifecycle, the plant will save nearly $52.5 million.
| Quantity | Cost | Annual Cost | |||
|---|---|---|---|---|---|
| Oil | 1,000,000 gal. | X | $3 /gal. | = | $3.0 million |
| Biomass | 22,000 tons | X | $40/ ton | = | $880,000 |
