What is Biomass Gasifier?

Biomass gasification is a process of converting solid biomass fuel into a gaseous combustible gas (called producer gas) through a sequence of thermo-chemical reactions. Biomass gasification means incomplete combustion of biomass resulting in production of combustible gases consisting of carbon monoxide (CO), hydrogen (H2) and traces of methane (CH4). This mixture is called producer gas. Biomass provides a clean, renewable energy source that could dramatically improve our environment, economy and energy security. Biomass energy generates far less air emissions than fossil fuels, reduces the amount of waste sent to landfills and decreases our reliance on foreign oil.

 

Biomass has been used as a source of heat energy since man first discovered fire. Many people around the world still burn wood as their primary source of heat during the winter. The use of bio fuels such as ethanol has been around for some time as well. It was used as a lamp fuel in the United States in the 1800s.

Producer gas obtain from Gasification can be used as substitute for Diesel, LPG, LDO, PNG , furnace oil in direct heat applications. Under present conditions, economic factors seem to provide the strongest argument of considering gasification. In many situations where the price of petroleum fuels is high or where supplies are unreliable the biomass gasification can provide an economically viable system . Some of the silent features of Biomass Gasifier are:-

 

  • Biomass is always and widely available as a renewable source of energy.

 

  • It reduces the overreliance of fossil fuels

 

  • The cost of Biomass is much less than Fossil fuels.

 

  • Low initial investment

 

  • Better conversion efficiency

 

  • Production of clean gases in the exhaust

 

  • Substantial reduction in diesel/kerosene/furnace oil cost since 3-4 kgs of biomass can replace 1 liter of petroleum fuel.

 

  • Biomass gasification is gaining an increased attention as it results in a significant reduction of the CO2 emission compared to fossil fuels and also produces high calorific gas from a renewal energy resource.

 

  • Can be customized for a variety of application.

Use of Biomass Gasifier

Importance and role of Gasifier in Shaping future 

 

Alterations to the climate due to temperature rise caused by the greenhouse effect pose a risk to humanity, and other species. Greenhouse gas (CHG) emissions from anthropogenic activities such as the burning of fossil fuels for power generation and other production of many materials are major contributors to climate change. This necessitates a switch from conventional to renewal power sources. Gasification is a robust technology that has been demonstrated successfully at industrial scale and shown to be able to achieve high conversion efficiencies and relatively low production costs. this is a technology suitable for large-scale production of second-generation biofuels from residual forest biomass.

 

Biomass utilization has an advantage over other renewal sources as it is less dependent on location and climate and biomass is easily storable and transportable. Also it is abundantly available.

 

Furthermore, waste biomass is often more readily available and can be equally as useful as a low-cost fuel. This makes it viable and promising as an energy source. Developed countries are also focusing on biomass as a sustainable energy option since it is abundant and has a lower environmental impact compared to fossil fuels.

 

Gasifier application plays key role in biomass utilization same as a renewable power resource by the gasification process; gasification is the thermo-chemical method by which carbonaceous (hydrocarbon) ingredients (like coal, petroleum coke, and biomass) can be transformed into synthesis gas or producer gas.

 

Energy demands will increase as industrialized nations strive to maintain progress and productivity gains and as developing nations increase their consumption and productivity. One direction that is evolving to satisfy the demand while minimizing environmental impacts is to move toward a Gasification economy. For the foreseeable future, the majority of these demands will be met through the increased usage of fossil fuels. One of the most abundant and readily available fuels is wood. Purpose Biomass gasification represents a viable alternative to improve innovative energy processes.

Why Manglam  Biomass Gasifier?

A complete system for Gasifying Biomass:

  • It serves as a simple and reliable solution for bringing down the fuel cost by over 50%.

  • It replaces expensive liquid/gaseous fuels like L.D.O./F.O./CNG/LPG/Diesel by low cost solid fuels without any changes in operations, temperature profile, temperature control and cleanliness in the plant area.

  • Typically the cost of replacing 1 liter/kg of liquid/gaseous fuel works out to be Rs 15 to 20, depending on the application and type of fuel used for gasification

  • It offers clean combustion; compact burning equipment, high thermal efficiency and a good degree of control just like conventional diesel burner.

  • Clean working environment as the Gasifier system is situated away from the load

  • Zero Tar/ Effluent system & highest overall efficiency

  • Payback period 6-8 months

  • Reduce oil import

  • No emission of smoke from the Gasifier

  • Worldwide environment friendly accepted renewable technology

Savings Analysis 

Depending upon the moisture content available in the wood, one liter of oil can be saved through the use of 3.5 to 4 kg of wood. The economical benefits derived in terms of cutback in the fuel costs can be easily evaluated by comparing the likely prices of biomass materials with an outlay of liquid fuels.

Comparing the calorific values of different fuels vis-à-vis producer gas, the Biomass Gasifier System uses wood to produce producer gas which after cleaning process is just like LPG, and can be used for various industrial applications.

By processing 1 kg of wood into a Biomass Gasifier, it transforms the wood into 2.4 nm3 of producer gas, which has a calorific value of 1000-1200 kcal/nm3 In other words, 1 kg of wood yields the calorific value of 2640 kcal after being converted into producer gas.

The calorific values of different fuels are as under:

Savings analysis for using producer gas vis-à-vis other fuels. The Base values that are taken for calculations are as under : 1 kg of wood / briquettes = Rs 5.00/kg
