The combustion chamber of the residue and multi-slurry gasifier is insulated with refractory bricks, and the refractory bricks are used for the thermal insulation lining of the gasifier There are many disadvantages, such as easy wear, high shell wall temperature, refractory bricks need to be replaced regularly, and the manufacturing, installation, maintenance and replacement of refractory bricks increase the operation cost of the furnace. In addition, the gasifier adopts the cooling mode of quenching ring, and the temperature of the syngas out of the combustion chamber is reduced from 1300 degrees to about 900 degrees, and after entering the quenching chamber for cooling, the waste heat of the high-temperature syngas is not fully recovered, resulting in great energy waste.
A gasifier device that can meet the requirements of waste liquid gasification, reduce the maintenance cost of the furnace, and efficiently recover waste heat has been applied for a patent.
