2.1 Gasification And Internal Combustion Engine Internal combustion (IC) engines, particularly gasoline and diesel-fuelled engines are readily available for small-scale electricity generation. They have low capital cost, have a high uptime (>95%), and qualified maintenance personnel are readily available. In terms of heat recovery (i.e. for CHP application) heat can be recovered from the engine oil, jacket water (~30%) and exhaust (up to 50%). The ready availability of IC engines makes them an appealing basis for biomass CHP. Add to this the fact that gasification and combustion of syngas has been around for over a century; cars were run on gasifiers as recently as the Second World War. The inclination is to think that it must be simple to build a gasifier and an engine and start producing power and heat. Figure 2 - Simplification of CHP via Biomass Gasification Biomass gasification is achieved through the partial oxidation of the biomass feedstock (i.e., partial combustion whereby only about one third of the air normally required for full combustion is used). The untreated gas exiting the gasification chamber is known as producer gas. Producer gas contains (in addition to the nitrogen already in the air) primarily carbon monoxide (CO), and hydrogen (H2), with smaller amounts of methane (CH4) and carbon dioxide (CO2), a small fraction of CH4, traces of other hydrocarbons (C2+C3), tars, particulates and other undesirable species such as NH3, HCN, H2S and SO2. Producer gas is a low quality gas with a heating value of 4-6 MJ/Nm3 or just over one tenth the energy content of natural gas at 40 MJ/Nm3. Producer gas can be burned directly in a boiler to generate heat, although the cost of gasification followed by direct combustion will generally be much higher than just burning the biomass feedstock directly. The low energy content of producer gas is a challenge, but not insurmountable, for IC engines. Much more significant is the presence of heavy organic tars in the produced gas that condense and adhere to the conduits and internal components of the engine causing fouling and unacceptable engine wear. Gasification can be carried out with oxygen and steam, however for purposes of this report only air driven gasification is considered as this is the basis for most small-scale CHP systems. Air- based biomass gasification efficiency, defined as how much of the energy in the original feedstock ends up in the producer gas is typically around 75%. 9PDF Image | Yukon Biomass Electrical Generation
