Product Description

Description:

Coal gasifier is euqipment which supplies the mixed gas to the heat process workshop in the field of machinery,metallurgy,building materials,light industry,chemical,and refractory.Coal gasifier is equipped with Equipment of adding coal,it adopt double clocks which can load the coal automatically,and wet ash tray which can get rid of the slag automatically.The drive equipments of Furnace grate mechanical drive are all designed in the outside,so it has features like reliable operation,easy installation and maintenance.Water jacket of the gasifier and the steam drum are both low pressure equipment,they all designed through the intensity calculation,they are manufactured with the strict requirements.Before delivery,the products should be checked carefully in order to control the quality.The steam generated by the gasifier is used to blowing the wind in the bottom and supply the pressure of poking hole and steam seal in the roof,by doing this,additional team is not necessary in the production,then the energy consumption is reduced.

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.

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.
