THERMAL STORAGE - Watson Research - Home

With wood gasification, combustion efficiencies of 90% can be realized. This results in a tremendous amount of heat. With efficient heat exchange to the system water, flue gas entering the chimney can be regulated to around 350 degrees F. The boiler controls could be adjusted for even better thermal efficiency, but this could result in costly damage to the chimney as a result of the condensation of flue gases before leaving the chimney. The best indicator of good combustion …

Supercritical water gasification: a patents review

Supercritical water gasification (SCWG) is a very recent technology that allows conversion of organic wastewaters into a fuel gas with a high content of hydrogen and light hydrocarbons. SCWG involves the treatment of organic compounds at conditions higher than those that define the critical point of water (temperature of 374°C and pressure of 221 bar). This hydrothermal process, normally
