 Straw Burning Hot Water Boiler. ST BOILER. TENZA a.s. has developed a straw burning hot water boiler with financial assistance of the Ministry of Industry and Commerce of the Czech Republic provided in the form of a grant. Straw can replace other, especially fossil fuels (natural gas, propane-butane, fuel oils and possibly coal, etc.).Learn More Straw to Energy - Hermes EPC Group The straw boiler is built as a natural circulation boiler. The water which reached a high level of pressure caused by the feed water pump vaporizes in the walls of the boiler. This vapor is heated up to the final, required temperature by the super heater in the steam drum and is fed to the turbine.Learn More Biomass Boiler - an overview | ScienceDirect Topics A Straw/coal mix B Straw-boiler moderate temp.
