Problems solved by technology

However, if the heat recovery rate is to be improved, the length of the burner must be lengthened, and the temperature of the exhaust gas will decrease, which will cause the temperature of the exhaust gas to reach the corrosion temperature of sulfuric acid dew point, which will damage the part or the whole of the regenerative burner

Abstract

The invention relates to a heat accumulating type burner which comprises a burner body and a heat accumulator storage body connected with the burner body; a cavity is arranged inside the burner body; a fuel tube is arranged in the cavity; one end of the fuel tube is positioned outside the burner body; a U-shaped passage is arranged in the heat accumulator storage body; a heat accumulator is arranged in the U-shaped passage; and one end of the U-shaped passage is communicated with the cavity, and the other end is connected with an exhaust pipe. A metal steel body is not required to be adopted for holding the heat accumulator. Compared with the existing mode, the condition that the temperature of burning tail gas is lower than that of a sulfuric acid leakage point, so that the sulfuric acid leakage point of a metal net plate is corroded is avoided. The collapse and the toppling down of the heat accumulator due to the corrosion and degradation loss of the net plate for holding the heat accumulator are not worried.

Description

technical field [0001] The present invention relates to the technical field of burners, in particular to a regenerative burner. Background technique [0002] The regenerative burner can not only efficiently recover the waste heat in the combustion exhaust, but also preheat the combustion air. In the prior art, for the ceramic ball or honeycomb body containing the heat accumulator, the impact-resistant metal mesh plate is used at the lowermost low temperature. Therefore, in order to avoid sulfuric acid dew point corrosion caused by sulfur oxides in the exhaust gas, the exhaust gas whose temperature is below 180°C to 200°C is usually not recovered. [0003] The structure of the existing regenerative burner is as follows Figure 5 As shown, it includes a burner tile 54 made of refractory material arranged in the furnace wall 53, a fuel nozzle 55 is arranged in the burner tile 54, and the burner portion 51 and the heat storage portion 52 are connected in series, and the storage...
