The present invention will be further explained with reference to the accompanying drawings.

Please refer to fig. 1.

The gas producer of the utility model comprises a producer body 10. The top of the furnace body 10 is connected to the bottom of a top bunker 16 through a coal feeder 15. The bottom of the furnace body 10 is connected to a blower 19 through an air inlet pipe 17. The bottom of the furnace body 10 is fixed on a base 11, and the base 11 is fixed on a base support 11 a. The bottom of the furnace body 10 is also provided with a grate 12. An ash tray 14 is arranged on the base support 11a, and the ash tray 14 is arranged below the bottom of the furnace body 10. A water jacket 13 is fixed on the outer wall of the furnace body 10. The upper end of the water jacket 13 is connected to the top of a steam drum (not shown) through a steam pipe 13 a. The lower end of the water jacket 13 is connected to the bottom of the steam drum through a preheating water pipe 13b, and the top of the steam drum is also communicated to one end of the air inlet pipe 17 close to the furnace body 10 through a steam inlet pipe 18. The upper part of the furnace body 10 is also provided with an air outlet pipe 100.

The utility model discloses prevent that gas leakage structure includes a gas storage bag 21. The top of the top bunker 16 passes through a first shut-off valve 22 to the bottom of the storage vessel 21.
