High quality best Coal Gasifier plant
Coal Gasifier is designed to be high production capacity, high gasification efficiency and better adaptability to various coals, high gas calorific value, and only need two worker to operate it, our coal gasifier can cope with different type heating furnace, kiln, steam boiler and ect.
Our company design and manufacture environmentally friendly coal gasifier that based on the air and steam as gasification agent and is the advanced equipment that produce mixed gas. The equipment is suitable for gasifying coking coal, coke and other fuels, are widely used as furnace kiln of machinery, metallurgy, chemical industry, glass, building materials, light industry, food, textile industry.
1.coal gasifier is the process of producing coal gas, a type of syngas-a mixture of carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H2O)-from coal and water. Coal gas, which is a combustible gas, was traditionally used as a source of energy for municipal lighting and heat before the advent of industrial-scale production of natural gas, while the hydrogen obtained from gasification can be used for various purposes such as making ammonia, powering a hydrogen economy, or upgrading fossil fuels. Alternatively, the coal gas (also known as "town gas") can be converted into transportation fuels such as gasoline and diesel through additional treatment via the Fischer-Tropsch process.
2.Process of the coal gasifier
During gasification, the coal is blown through with oxygen and steam (water vapor) while also being heated (and in some cases pressurized). If the coal is heated by external heat sources the process is called "allothermal", while "autothermal" process assumes heating of the coal via exothermal chemical reactions occurring inside the gasifier itself. It is essential that the oxidizer supplied is insufficient for complete oxidizing (combustion) of the fuel. During the reactions mentioned, oxygen and water molecules oxidize the coal and produce a gaseous mixture of carbon dioxide (CO2), carbon monoxide (CO), water vapour (H2O), and molecular hydrogen (H2). (Some by-products like tar, phenols, etc. are also possible end products, depending on the specific gasification technology utilized.) This process has been conducted in-situ within natural coal seams (referred to as underground coal gasification) and in coal refineries. The desired end product is usually syngas (i.e., a combination of H2 + CO), but the produced coal gas may also be further refined to produce additional quantities of H2:
3C (i.e., coal) + O2 + H2O → H2 + 3CO
If the refiner wants to produce alkanes (i.e., hydrocarbons present in natural gas, gasoline, and diesel fuel), the coal gas is collected at this state and routed to a Fischer-Tropsch reactor. If, however, hydrogen is the desired end-product, the coal gas (primarily the CO product) undergoes the water gas shift reaction where more hydrogen is produced by additional reaction with water vapor:
CO + H2O → CO2 + H2
Although other technologies for coal gasification currently exist, all employ, in general, the same chemical processes. For low-grade coals (i.e., "brown coals") which contain significant amounts of water, there are technologies in which no steam is required during the reaction, with coal (carbon) and oxygen being the only reactants. As well, some coal gasification technologies do not require high pressures. Some utilize pulverized coal as fuel while others work with relatively large fractions of coal. Gasification technologies also vary in the way the blowing is supplied.
3.The features of coal gasifier:
1.Small investment of the main equipment,run fast.
2.Safe and convenient using,simple operation,can save 20% fuel than direct coal.
3.Compared with the heating furnace of direct fuel,use hot gas can save energy economy more than 60%
4.Have a significant effect of smoke prevention and dust control,meet environmental protection requirements, is the important equipment of hot working system.
5.Gas outlet temperature is 400-550 °C, the heat energy utilization rate is extremely high.
