The gasification process includes a precision engineered and fabricated biomass conversion system that has unmatched efficiency and environmental benefits. It is an advanced and advantageous method used to convert wood waste, biosolids, solid waste and most organic based feedstocks into a syngas fuel for co-generation of electrical and thermal energy.
The 3i Gasification is a fixed bed, linear downdraft gasifier and produces a high quality gas suitable for any application, including fuel for internal combustion engines, turbines and heat applications. It has no moving parts and is designed and fabricated to rigid specifications and from the highest quality stainless steel and titanium.
The 3i Gasification utilizes a process that reaches optimum temperatures minutes after startup, producing a high octane, tar-free gas. High (1,200°C to 1,300°C) temperatures ensure near-complete decomposition or cracking of the feedstock material and any otherwise undesirable compounds, thus ensuring an environmentally friendly producer gas that is suitable for any application.
To satisfy increasingly strict emissions regulations, engines that utilize alternative gaseous fuels are now widely used. Natural gas and synthesis gas appear to be greener alternatives for internal combustion engines. In many situations where the price of petroleum-derived fuels is high or where supplies are unreliable, the syngas, for example, can provide an economically viable solution. Syngas is produced by gasifying a solid fuel feedstock such as coal or biomass. The gasification of biomass means near-complete combustion of biomass resulting in production of combustible gases. Syngas consists of about 40% combustible gases, mainly carbon monoxide (CO), hydrogen (H2) and methane (CH4). The rest are non-combustible gases and consists mainly of nitrogen (N2) and carbon dioxide (CO2). Varying proportions of CO2, H2O, N2, and CH4 may be present.
H2 as a main component of a syngas has very clean burning characteristics, a high flame propagation speed and wide flammability limits. H2 has a laminar combustion speed about eight times greater than that of natural gas, providing a reduction of combustion duration and as a result, an increase in the efficiency of internal combustion (IC) engines, if the H2 content in the gaseous fuel increases. The main point of interest in increasing H2 content in the gaseous fuel is that with the addition of H2, the lean limit of the gas operation can be extended, without going into the lean misfire region. Lean mixture combustion has a great potential to achieve higher thermal efficiency and lower emissions. In particular, the lean mixture combustion will result in low and even extremely low NOx levels with only a slight increase in hydrocarbons.
Greenhouse CHP Gasification
For greenhouse growers, our proprietary gasification process is an ideal way to convert biomass generated from recovered crop materials into useful, reliable and economical electricity, thermal energy and crop growth-enhancing CO2. With gasification, there is minimal remnant ash and GHG emissions from the gasification process ensuring that maximum calorific yield is achieved from all input materials.
