Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0057] Coal chemical industry is an important way to utilize coal resources in a clean and efficient manner. Through high-temperature and high-pressure reactions, coal is converted into synthesis gas with CO and H2 as the main components, which is used in chemical fields such as methanol, coal-to-hydrogen, coal-to-gas, and coal-to-ethylene. Coal gasification technology is one of the important technologies in the field of coal chemical industry, and its core equipment is the gasifier that produces gasification reaction. The characteristics of the water-cooled wall gasifier are that the furnace is constructed of water-cooled walls and is installed and fixed inside the pressure shell of the gasifier. Compared with the refractory brick gasifier, the furnace of the water-cooled wall gasifier does not require regular replacement of refractory bricks, has less maintenance work, higher cold gas efficiency, and wider adaptability to coal types, so it has been widely used. The radiation waste boiler gasifier adds a radiation waste boiler to the outlet of the furnace of the above-mentioned water-cooled wall gasifier to recover the heat of the flue gas, which can reduce energy waste. The steam-water system of the radiation waste boiler gasifier generally adopts a forced circulation method. Forced circulation uses a pump as a power source to make water or a steam-water mixture flow in the circulation loop of the steam drum-downcomer-heating surface-upcomer. This circulation method is always powered by a pump, which consumes more energy and has higher operating costs.

[0058] In view of this, an embodiment of the present application provides a gasification furnace device to overcome at least one of the above-mentioned technical problems.

[0059] See also Figure 1In the embodiment of the present application, the gasifier device includes a drum 10, a furnace body 20, a first circulation component 30, a second circulation component 40 and a bypass pipeline 50. A furnace 21 and a waste boiler 22 are provided in the furnace body 20. The first circulation component 30 includes a first pipeline 31 and a second pipeline 32, and the first pipeline 31 and the second pipeline 32 are respectively connected to the drum 10 and the furnace 21, and are used to connect the drum 10 and the furnace 21 to form a circulation loop. The second circulation component 40 includes a third pipeline 41 and a fourth pipeline 42, and the third pipeline 41 and the fourth pipeline 42 are respectively connected to the drum 10 and the waste boiler 22, and are used to connect the drum 10 and the waste boiler 22 to form a circulation loop. The bypass pipeline 50 is respectively connected to the drum 10 and the waste boiler 22, and is used to connect the drum 10 and the waste boiler 22. Specifically, the drum 10 has an inlet and an outlet, and the inlet can be used to pass circulating water into the drum 10, and the outlet can output steam. When the furnace body 20 is working normally, circulating water is introduced into the inlet of the drum 10, and the circulating water enters the furnace 21 through the first pipeline 31. Since the furnace 21 is undergoing a gasification reaction, heat is generated to heat the circulating water and turn it into steam. The steam enters the drum 10 again through the second pipeline 32, is discharged from the outlet of the drum 10, and enters the pipe network; at the same time, the circulating water in the drum 10 also enters the waste boiler 22 through the third pipeline 41, is heated by the waste boiler 22, turns it into steam, and enters the drum 10 again through the fourth pipeline 42 and is discharged from the outlet of the drum 10. Both of these circulating pipelines need to be powered by a pump to circulate the steam and water. A bypass line 50 is added to the pipeline, so that the circulating water in the steam drum 10 enters the waste boiler 22 through the bypass line 50, is heated by the waste boiler 22, and becomes steam, and the steam then enters the steam drum 10. In this process, after being heated by the waste boiler 22, the density of the steam-water mixture in the pipe is smaller than the density of the circulating water, and the circulating water in the bypass line 50 is not heated, so the bypass line 50 is all circulating water without steam. In this way, there is a density difference between the heated steam-water mixture and the circulating water in the bypass line 50, and the force generated by the density difference becomes the power of natural circulation, so that there is no need to provide power through a pump, which reduces energy consumption, saves energy, and reduces operating costs.

The circulating water output from the second output end 13 of the steam drum 10 enters the second downcomer 411, and then enters the second power element 412. The power applied to the circulating water by the second power element 412 allows it to enter the second heating element 413.
