External mixing type glass polishing combustor

Abstract

The invention discloses an external mixing type glass polishing combustor which comprises an inner cavity pipe and an outer cavity pipe which sleeve together, wherein a first combustion medium channel is formed in the inner cavity pipe; a second combustion medium channel is formed between the inner cavity pipe and the outer cavity pipe; the first combustion medium channel and the second combustion medium channel are independent and are not communicated; a first combustion medium inlet is formed in the inner cavity pipe; a second combustion medium inlet is formed in the outer cavity pipe; a plurality of spraying holes I are formed in the inner cavity pipe; a plurality of spraying holes II are formed in the outer cavity pipe; and the spraying holes I and the spraying holes II are arrayed coaxially. By the adoption of external mixing combustion, the energy can be saved by 30 percent, and the safety is reliable; tempering is completely avoided, and the service life is long; harmful gas such as CO, CN and SO2 can be effectively reduced; and the indoor smoke content is greatly reduced. By the adoption of high-quality stainless steel materials and copper materials, the external mixing type glass polishing combustor has the functions of metering, pressure stabilizing, leakage alarming and the like and is of an integrated safe structure, and the heating temperature of a gun body is low.

Description

technical field [0001] The invention relates to an external mixing type glass polishing burner. Background technique [0002] For many years, in the glass industry, traditional internal mixing polishing burners have been used for polishing glass products. This internal mixing polishing burner has the following defects: [0003] 1. Poor security [0004] Due to the influence of the structure, the traditional polished burner cannot fully adjust the ratio of gas and oxygen, and cannot achieve the best combustion effect (the maximum calorific value of the gas cannot be released). If the optimal calorific value is achieved, the oxygen can only be increased. Proportion. In this case, the chances of flashback are greatly increased. Therefore can only adopt the mode of wasting part energy to guarantee safety (energy waste rate is about about 10%). [0005] 2. Poor energy saving [0006] The traditional polishing burner adopts the internal mixing method. The gas and oxygen are a...

AI Technical Summary

Problems solved by technology

Therefore, only the way of wasting part of energy can be used to ensure safety (energy waste rate is about 10%)

[0005] 2. Poor energy saving

Because this polishing method is greatly affected by pipeline pressure, once the pipeline pressure fluctuates and is affected by external glass products, it is easy to cause tempering of the polishing burner, resulting in safety hazards

[0007] 3. Easy to generate heat

[0008] Due to structural reasons, the traditional internal mixing polishing burner cannot separate the flame from the gun head during use, resulting in heat generation at the polishing burner head. Due to the high temperature, the service life of the polishing burner head is seriously shortened (heat loss)
