The gasifier uses biomass fuels such as CCA or creosote impregnated waste wood and other kinds of recycled wood to produces syngas that is combusted on site.
Relationship of Boiler Pressure to Water Temperature in Steam Boilers. The temperature of heated water can exceed 212 °F when water is heated under pressure - producing superheated water than can flash to steam. See BLEVE EXPLOSIONS for details. However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 °F will be no more than about 220 °F.
The DP MaxSolo is a core product in DP Cleantech’s portfolio, consisting of a specialized, single-fuel ‘high pressure high temperature’ biomass boiler. Whether it is a ‘soft’ fuel such as wheat straw, or a ‘hard’ fuel such as wood, all components of the MaxSolo are specifically designed to maximize the performance from a chosen fuel.
Refuse, wood, and biomass boilers are similar to the utility radiant boilers and industrial boilers that burn coal. They fall into the category of “waste-to-energy” boilers. They differ only in the type of refuse, wood, or biomass they burn, and the fuel they burn may vary depending on the time of the year (e.g., autumn may bring more leaves).
Feb 05, 2020 · He explains that combustion in GE’s biomass-burning CFB is typically around 800-850 degrees Celsius; in a standard boiler, the temperature can reach 1,500° C.

There are three main types of boilers used for industrial processes or power generation: fossil fuel boilers, biomass or hog fuel boilers, and recovery boilers. Fossil Fuel. Fossil fuels such as coal, oil and natural gas are burned to heat water into steam. Biomass. Like fossil fuels, biomass fuels may be burned to heat water into steam.
Some biomass needs pre-treatment before the fuel is fed onto a combustion grate where it is burned. The heat from the combustion is used to fire the boiler, which in turn generates hot water or steam. The steam turns a turbine which produces electricity.

Woody biomass is commonly used for facility heating in three forms: whole logs or firewood, wood chips, and wood pellets. Systems are available from 6,000 British thermal units (Btu)/hr to over 100 million Btu/hr. Small systems, particularly small- and mid-size pellet and log systems, are available off-the-shelf from numerous manufacturers.
The main biomass boiler steam–water circulation system and natural circulation are explained in detail, followed by an explanation of the functioning of the steam drum. The chapter continues with a short introduction to flow theory to give readers some familiarity with pressure loss and flow calculations.
Wood burning boilers however, normally create considerable ash and soot build-up in the firetubes, resulting in inefficient heat transfer and a loss of steam pressure. Most wood-fired boilers require manual tube brushing. This means shutting down the boiler for hours while mill personnel brush the ash build-up from the firetubes.
HURST Biomass Boiler Systems are equipped with high temperature cast refractory ceramic lining for longer life. This cast refractory/ceramic lining was designed to be completely modular, which makes for easy repair and replacement.
When utilizing biomass as fuel, the high moisture content of the biomass affects strongly the combustion process such as lowering the flame temperature and/or the boiler efficiency. The low flame temperature could result incomplete combustion and/or other operational problems. To overcome these, biomass is often dried before combustion.
