Brief introduction of coal gasifier 
Coal Gasifier is advanced equipment for producing mixed gas with water and steam as gasifying agent This machine is applicable for gasifying fuel like coking coal or coke Coal Gasifier is widely used as heating furnace in mechanical metallurgy, chemical,
 Gasification is a process of partial combustion & reduction which converts solid combustible material into Gaseous fuel. Thus gasified fuel can be transported to user point and can be burnt efficiently. It is a Thermo Chemical Conversion. The equipment used for this process is called Gasifier. The Gasifier is extensively used for bio-mass and coal gasification.
The economic advantages over the cost of liquid fuels have made this technology more attractive for industrial purpose particularly for direct combustion applications. Due to Low level of pollution particularly air pollution when using biomass as fuel has made this technology more environment friendly towards Greenhouse gases.
For thermal applications, the technology has been well proven and gasifier systems are already working in numerous applications. The capacity installed so far covers a wide range of applications at different segments. The techno- economic Gasifier range is start from 900 KW (t) to 8000 KW (t). The greatest advantage of using this alternate fuel for energy is that the fuel costs of the companies are reduced by half, thus reducing their production cost. This is beneficial for their customers, as the products are offered at competitive prices.

HOW GASIFICATION PLANTS WORK?
Gasification is a thermo- chemical process, which converts solid carbonaceous material / fuel into useful clean gaseous fuel called Producer Gas. It is remarkable that this technology has completed almost century of a proven use all over the world.
This technology has been approved by all the organization of the world like UNO, UNDP, DOE, USA, FAO, MNES of GOI and the concerned government agencies of every nation. Many under- developed and developing countries have declared incentives to encourage the use of renewable & cleaner technology for energy generation.
 THE PERSUADED ADVANTAGE
Conversion of Coal / solid biomass into combustible gas offers all the advantages associated with using gaseous and liquid fuels such as clean combustion, compact burning equipment with high thermal efficiency and a good degree of control.
Greater Effluent System: Gasifier is designed to have minimum waste or by products.
Overall Efficiency: maximum overall thermal efficiency of the system is as high as 80%.
Degree of Automation: Gasifiers are provided with advanced automation features.
