BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 This is a schematic diagram of the structure of the utility model;

[0012] Figure 2This is a schematic diagram of the installation of the pipe body of the utility model.

[0013] In the above drawings, there are furnace body 1, air inlet 2, gasification port 3, water-containing interlayer 4, cold water inlet 5, cold water return joint 6, hot water outlet 7, high-aluminum refractory coating 8, pipe body 9, and angle iron 10. DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0015] like Figure 1 As shown, a gasifier includes a furnace body 1, air inlets 2 are provided on both sides of the furnace body 1, and a gasification port 3 is provided on the top of the furnace body 1. External air is sent into the furnace body 1 through the air inlet 2 for combustion of fuel, and the exhaust gas after combustion is discharged through the gasification port 3. The gasification port 3 is connected to an external exhaust gas treatment device.

[0016] A water-containing interlayer 4 is provided in the middle of the furnace wall, and a cold water inlet 5 is provided on the water-containing interlayer 4. A cold water return joint 6 is provided at the cold water inlet 5. The cold water return joint 6 is connected to an external cold water supply device. Cold water enters the water-containing interlayer 4 through the cold water inlet 5 and is then discharged from the hot water outlet 7 to be connected to the heating network for heating.

[0017] A high-aluminum refractory coating 8 is provided inside the furnace body 1. The provision of the high-aluminum refractory coating 8 can increase the thermal conductivity of the furnace body 1, thereby improving the heating efficiency of the cold water in the water-containing interlayer. It can also increase the internal heat capacity of the furnace body 1, thereby increasing the temperature inside the furnace, which is conducive to the secondary combustion of the fuel.

[0018] There are multiple air inlets 2 respectively arranged on the side walls of the furnace body 1 at the upper, middle and lower positions, so that air can enter the furnace body 1 evenly, making the combustion in the furnace body 1 more uniform and sufficient.

[0019] like Figure 2 As shown, a tube body 9 and an angle iron 10 for mounting the tube body 9 are provided at the air inlet 2. The tube body 9 at the air inlet 2 is connected to an external air supply device such as a blower to improve the oxygen supply efficiency in the furnace and make the fuel burn more fully.
