The ignition hole 2 is an ignition air opening, arranged at both ends of the secondary pipe section 12, with an aperture of Φ4.5, and a total of 96, which are used to form ignition conditions for the ignition gas here. The ceramic partition includes a first partition 6 and a second partition 7, both of which are made of corundum and are in a plurality of quantities, and are used to fix the pressure rod 4 and isolate the pressure rod 4 from the T-shaped gas pipe 1. The ceramic sleeve 3 is fixed to the T-shaped gas pipe 1 through a ceramic partition, and the ceramic sleeve 3 is used to insulate the pressure-conducting rod 4 from metal bodies such as the T-shaped gas pipe 1; the ceramic sleeve 3 is made of corundum, has an inner pore diameter of Φ6.3, and is sleeved on the pressure-conducting rod 4; the ceramic sleeve 3 includes a main sleeve section 31 and a secondary sleeve section 32, which are vertically connected, wherein the secondary sleeve section 32 is connected to the secondary pipe section 12 through a first partition 6, and the main sleeve section 31 is connected to the main pipe section 11 through a second partition 7.
