BiomassBEST gasifier burns straw, wood chips, manure …

The tarp covered bale conveyor protects the bales as well as feeding operation during winter.

Clean exhaust emissions as a result of better combustion process and particulate trapping.

Straw bales are abundantly available in prairies. Compared to any other fuel, straw is the cheapest and renewable.

When a community invests in a district heating system, and purchases straw from area farmers, the money stays in the community.

General Description

The configuration of the BEST heating unit is that of a gasifier/combuster controlled by a PLC. BEST believes that the ideal installation uses fuel originating in close proximity to the heating unit, and that the fuel requires minimal preparation. Other installations can be accomodated.


  • Our SmartFire technology consists of a computer monitoring temperature, vacuum and oxygen content at various points in the system. This information determines the amount of air injected at various points.
  • Fuel is injected as the system calls for heat. Air is optimized for the amount of fuel being burned.
  • Most of our installations depend on large bales of cerial straw, but other biomass fuels can also be used.
  • Our bale shredding system combined with a bale conveying system, allows for the loading of a one week supply of fuel at a time.

Our silica trap removes boiler clogging silica that occurs naturally in cereal straw. Unless these salts are dealt with, they will foul up any boiler. The most common biomass utilized in the BEST heating unit is post-harvest baled wheat straw. In many locations straw is the cheapest, accessible resource that is totally renewable. The gasification process in the BEST unit converts biomass to hot water or air. Models range from 1,000,000 Btu/hr to 20,000,000 Btu/hr. The smallest system producing one million BTU’s per hour and operating at full capacity requires approximately 170 pounds of straw per hour with moisture content from 10 to 15%.

What is the BEST System?

Biomass Energy System Technology Inc. has devloped the technology extract heat energy from biomass efficiently. Our automated system will produce heat day after day year after year. Biomass material, which is most often agriculturally generated straw or wood chips, is combusted on a grate. The fuel is fed continuously and automatically by a conveyor system. The heat of combustion is transferred to water in a boiler that is separate from the combustion unit. A hydronic system delivers this hot water to places where it is needed. Close control of combustion and heat output is maintained by synchronizing and automating the rate of biomass feed, the amount of combustion air intake and the temperature difference in inlet and outlet water temperature.

The combination of low operating cost and relatively high capital cost means that the BEST system is most appropriate for large loads operating with a substantial year round base load. Where the system operates near-rated capacity and with a high number of operating hours, the fuel savings cover the capital costs of a BEST System.
