Coal gasifier is named gasificaiton, it is the process of extracting maximum amount of energy from combustible materials like coal, biomass and other carbonaceous materials through heating in an environment of controlled oxygen. The insufficient supply of oxygen allows the material to combust, thereby, producing quality producer gas. However, in order to extract more usable producer gas, the carbonaceous material should contain moisture content in it or artificial steam should be supplied from outside. These days, coal usage has become widespread among manufacturing industries worldwide. The availability of coal reserves is much higher as compared to oil and gas reserves, which is the major reason behind the increasing use of coal gasification technology. Moreover, the increasing price of petroleum product like diesel, furnace oil, kerosene etc. has made coal-firing as primary choice, a relatively less expensive carbon-containing material. KEYUAN understands coal as an excellent material to compete against other fuels more effectively. Therefore, the company offers state-of-art gasification technologies which are more environment-friendly and efficient for a number of industrial applications.
