Patented Bio-Thermal Technology
“Creative destruction” refers to innovation
by which new products and/or processes
replace outdated ones.” - Joseph Schumpeter (1942)
Hot hearth biomass vaporization (HHBV) is a “creative destruction” example of an innovative replacement of outdated bio-waste gasification-to-energy technologies such as fluidized beds, pyrolysis and digesters by being simple, efficient, effective, expedient but NOT expensive.
The HHBV system is an auto-thermic (self-fueling) process that can break down any biomass into eco-friendly exhaust gases and inert residual ash.
System Components
(1) At start-up, a fossil fuel burner heats the ceramic hearth from beneath in the secondary chamber. (2) Once the hearth becomes hot enough to cause the overlaying biomass in the primary chamber to vaporize (endothermic process), oxidation of these bio-gases with fresh air (exothermic process), commences below the primary chamber window and continues on into the secondary chamber. (3) Once a steady state temperature of 850+C is reached in the secondary, the burner is shut down, resulting in an auto-thermic process.

The Brookes Gasifier when designed for a batch of bio-waste, the waste is loaded on top of the hearth, then heated until the exothermic generation of bio-gases is completed in the primary chamber causing the termination of the exothermic oxidation of the bio-gases in the secondary; therefore, shutting down the system.
Scalable Continuous Feed
Biomass Vaporization
The Brookes Gasifier when designed for a continuous source of bio-waste, uses a scalable number of augers to move the waste from a hopper across a hot hearth at a speed sufficient enough to have the waste completely converted to inert ash at the time of exit. The system can operate on a 24/7 basis as long as the feed stock can be moved continuously over the hot hearth by the augers.
