Description
| Introduction Coal gasification boiler refers to the main equipment for coal gasification. According to the nature of coal and different requirements for gas, there are various gasification methods. It is an upright cylindrical structure. The main body is divided into two parts. The upper part is the gasification chamber and the lower part is the radiation waste heat. The boiler is connected to the ash lock bucket. Working Principle After the oxygen and the coal water slurry are respectively pressurized by the compressor and the pump, the feed nozzle from the top of the gasification furnace enters the furnace, and the gasification reaction is carried out at a high temperature. The generated gas is chilled in the waste heat boiler, and is taken out from the center after the initial cooling. The gasification operation temperature is controlled above the ash melting point of the coal, and the ash is discharged through the ash lock bucket. Characteristics The gasification temperature of the coal gasification boiler is very high, and it is a cocurrent operation. The heat efficiency in the furnace is low. At the same time, it is fed with coal water slurry, and the carbon dioxide content in the gas is high. Therefore, increasing the concentration of coal in coal water slurry is an important part of this gasification method. The concentration of coal in coal water slurry is directly related to the nature, particle size and particle size distribution of coal. Adding a suitable additive can reduce the viscosity of the coal water slurry, thereby obtaining a higher concentration of coal water slurry. Advantages 1) High temperature pressurization operation, high gasification intensity; 2) The generated gas pressure is higher, saving the power of the subsequent process; 3) The raw materials have wide adaptability, and different types of coal can be used, and the residue after coal liquefaction can also be used; 4) The solid coal is made into the coal water slurry fluid transportation, which simplifies the pressurized feeding device; 5) The wastewater contains no tar and phenol, and the environmental pollution is not serious.Coal Fired Steam Boiler price website:http://www.jn-boiler.com/coal-fired-boiler/coal-fired-steam-boiler/ |
