Inorder to promote healthy atmosphere, the use of many fuels which releases carbon emissions into the atmosphere has to be reduced. Heating the coal under controlled conditions with insufficient air to provide complete combustion produces a gaseous fuel known as syngas, which is also known as town gas. Coal has been gasified ever since the industrial revolution to produce "town gas".This was once done in the local gas works, and every town had one.
The advantage of Coal gasification is that the use of synthesis gas as fuel and its origin is more than direct combustion, because the high temperature fuel cells can be burned. Carnot's rule can be efficient or effective as on the thermodynamics of the upper limit not apply. Internal combustion engine directly used to produce methanol and hydrogen, or Fischer-Tropsch synthetic fuel in the process of change for the manufacture of. Biomass gasification or biological wastes that are not seful as fuel. In addition, the high-temperature combustion refines out corrosive ash elements such as chloride and potassium, allowing clean gas production from otherwise problematic fuels.
Oxygen gasification or steam at high temperatures with the control of the reaction of the raw materials from coal, oil or biomass, such as carbon monoxide and hydrogen for the conversion of carbonaceous materials is one method. Gasification is a very efficient method[citation needed] for extracting energy from many different types of organic materials, and also has applications as a clean waste disposal technique.
Coal gasification technology is at the forefront in the efforts to develop alternatives for conventional furnaces. It is of particular interest because it offers an opportunity to use the product fuel gas in integrated gasification combined-cycle electric power generation (IGCC). Great hopes are pinned on IGCC as a highly efficient and low polluting emissions technology. Gasification can also be fueled by materials that are not otherwise useful fuels, such as biomass or organic waste.
