Embodiment Construction

[0016] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings. as attached figure 1 , 2 As shown, the lower part of the dual regenerative burner of the present invention is a gas collection chamber 9 and an air collection chamber 10, and a gas inlet 1 and an air inlet 11 are arranged on the side wall of the gas collection chamber for connecting with external gas The tube is connected to the air tube. The upper part of the gas collection chamber 9, 10 is the regenerator 4, 12, the outside of the regenerator is a metal cavity 25 of steel structure, and the inner side of the metal cavity 25 is lined with a heat insulating material 8 for heat preservation and a high temperature resistant high temperature refractory material 7. A refractory partition wall 6 is built in the regenerator chamber to divide the regenerator chamber into a gas regenerator chamber 4 and an air regenerator chambe...

Abstract

The invention discloses an air and gas double heat accumulating type burner, and belongs to the technical field of fuel combustion. The air and gas double heat accumulating type burner comprises a burner body and a burner block, wherein the burner block is provided with an ignition hole, the burner body is a metal cavity built with a lining made of a refractory material, and a gas heat accumulation chamber and an air heat accumulation chamber are arranged in parallel in the metal cavity and partitioned by a partition wall made of the refractory material; a gas passage communicated with the gas heat accumulation chamber passes through the upper part of the air heat accumulation chamber and is communicated with a gas spout of the burner block at the front end; and a primary air passage communicated with the air heat accumulation chamber is communicated with an inflaming chamber in a certain angle, and a secondary air passage communicated with the air heat accumulation chamber is led to the outside of the burner block along the periphery of the inflaming chamber. The air and gas double heat accumulating type burner has the advantages of novel structure, reasonable design and remarkable technical effect. The burner has a compact structure and adopts a combined structure, so the maintenance and replacement of the burner are convenient and the connection of the burner and a furnace body is tight.

Description

technical field [0001] The invention belongs to the technical field of fuel combustion, in particular to the technical field of combustion devices for industrial kilns using coal gas as fuel. Background technique [0002] In industrial furnace technology, there are two devices for heating coal gas or combustion-supporting air by using the waste heat of furnace exhaust gas, one is a heat exchanger, and the other is a regenerator. [0003] Heat exchangers were invented in 1828, and most of them are made of metal. Industrial furnaces use heat exchangers, on the one hand to recover waste heat from exhaust gas, and on the other hand to increase the combustion temperature. Due to the poor high temperature resistance of metal heat exchangers at that time, the preheating temperature of air or gas was very low, so that the combustion temperature of some furnaces could not meet the requirements of the smelting process. [0004] In 1858, William Siemens invented the regenerator at th...
