Abstract

The invention discloses a transformation method for a boiler, and by means of the transformation method, a built-in fuel oil burner is transformed into an external oil gas double-fuel burner. The original boiler with the built-in fuel oil burner comprises a front backdraft chamber, the built-in fuel oil burner, an air blower, an air flue, an interlayer air chamber and a smoke outlet. A fireproof wall is arranged between the front backdraft chamber and the interlayer air chamber. The air blower is communicated with the interlayer air chamber through the air flue. The built-in fuel oil burner is arranged in the interlayer air chamber and penetrates the fireproof wall to be communicated with the front backdraft chamber. The transformation method for the boiler includes the steps that the built-in fuel oil burner is detached, and the external oil gas double-fuel burner is arranged; the connection position of the air flue and the original interlay air chamber is sealed, and the air flue is communicated with the external oil gas double-fuel burner; and the original interlay air chamber is filled with insulating materials. The transformation method is simple and easy to operate, and resources are saved.

Description

technical field [0001] The invention relates to a boiler transformation method, in particular to a boiler transformation method in which a built-in oil burner is changed to an external oil-gas dual-fuel burner. Background technique [0002] At present, domestic cities are facing the problem of how to transform traditional boilers. Since natural gas is a high-quality energy source that is close to environmental protection, it contains almost no sulfur, dust and other harmful substances, and produces less carbon dioxide than other fossil fuels during combustion. Fundamentally improve the quality of the environment. In addition, gas also has the advantages of being economical, safe and reliable. It is the general trend to replace fossil fuels with gas. [0003] External oil-gas dual-fuel burner boilers can meet the needs of this situation. First of all, the boiler can use natural gas, an environmentally friendly energy source, for combustion. Secondly, when natural gas condit...
