Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of variable furnaces, in particular to a steam generation optimization mechanism for a gasified waste boiler. Background Art
[0002] Since the gasifier produces steam as a byproduct, steam exhaustion is inevitable. The initial feeding and starting of the gasifier has a good heat exchange effect in the boiler and a high steam output, but it will cause the outlet temperature of the gasifier to be low, resulting in a low water-steam ratio, which seriously affects the conversion rate. At the same time, after a long period of operation, the steam output of the gasifier gradually decreases, and the water-steam ratio of the gasification conversion synthesis gas thermometer increases accordingly. However, the current conversion uses 9.8MPa high-pressure superheated steam. This steam is superheated steam with a temperature of 520°C. Due to the high temperature, it is necessary to add cooling and pressure-reducing water when adding it, and the material of the equipment should also be improved. Ensure equipment and production safety. The materials of the conversion system are lower than the materials of the 9.8MPa steam pipeline network. If 9.8MPa steam is connected to the conversion system, if the cooling and pressure-reducing water is not added in time, it will cause damage to the conversion equipment and pipelines. A gasification waste boiler steam production optimization mechanism is provided to solve the problems raised in the above background technology. Utility Model Content

[0024] Among them, the conversion gas enters the conversion furnace body 1 through the intake pipe 101, and then the conversion gas will produce a chemical reaction with the first catalyst screen plate 2, and then pass through the first cooling pipe 3 and the second cooling pipe 303, so that the conversion gas will produce a chemical reaction with the high temperature and then be discharged through the second catalyst screen plate 201, thereby improving the conversion rate of the conversion gas into carbon monoxide.
