Gasifiers offer a versatile and efficient solution across various industries, catering to diverse applications that are currently fuelled by any solid, liquid, or gaseous fuels. Whatever the objective - fuel flexibility, cost reduction, or environmental responsibility, gasifiers deliver exceptional value.
This is the primary purpose of a gasifier installation in most of the cases. Gasifiers convert low-cost fuels, like biomass, low-grade coal or waste materials into a clean combustible gas that can substitute costly petroleum derived liquid or gases fuels. Such fuel substitution is feasible in any kind of furnace catering to any type of application or even in engine-generator sets. The savings are usually extremely attractive leading to payback periods of less than 2 years in most cases.
In the dynamic and volatile fuel price scenarios, as they exist today, fuel flexibility becomes important for long-term viability of a project. Gasifiers offer the option of switching from one fuel to another depending upon market conditions. In such large projects, wherein fuel is the major cost contributor, our customers are incorporating gasifiers right from the conceptualization stage.
The use of sulfur containing liquid fuels (e.g., furnace oil) is restricted in many regions. Also, particulate matter emissions are prohibitive when direct solid fuel combustion is employed. Gasifiers convert solid fuels into clean gas. The stack emissions from combustion of clean producer gas are normally within stipulated limits.
Finer controls are possible with gaseous combustion as compared to the combustion of liquid or solid fuels.
This is relevant in the case of heating of metals. Solid and liquid fuel combustion requires higher amounts of excess air as compared to gaseous combustion. So, substituting solid or liquid fuel by producer gas from gasifier results in reduction in oxidation (burning) loss of metal being heated.
Industrial heating is mostly addressed by burning solid, liquid, or gaseous fossil fuels. Gasifiers convert solid biomass into a clean combustible gas that can substitute fossil fuels in almost any industrial heating process.
You can substitute any fuel in furnaces and kilns with clean producer gas from gasifiers. There is no upper limit of capacity (limited only by availability of fuel for gasifier). Temperatures up to 1400 0C can be achieved by appropriate selection / design of combustion system. Also, there are no limits with respect to achieving any type of process control.
Decentralized / on-site power generation is mostly done using solid (e.g. coal), liquid (e.g. diesel, fuel oil), or gaseous (e.g. natural gas) fossil fuels. Gasifiers offer the opportunity for fuel cost reduction by switching to a cheaper fuel. When fuel switching is done by use of biomass, decarbonization is also achieved.
Typical CHP application involves converting solid fuels into gas in a gasifier, generating power by feeding the gas into an engine, and using the waste heat from the engine for a thermal application.
