Abstract

The invention discloses a boiler transformation method for changing a built-in fuel burner into an external oil-gas dual-fuel burner. chamber, flue gas outlet, a fire-resistant wall is set between the front back-firing chamber and the interlayer air chamber, the blower communicates with the interlayer air chamber through the air duct, and the built-in fuel burner is set in the interlayer air chamber, and passes through the fire-resistant wall and the front back-firing chamber connected. The transformation method of the present invention includes: removing the built-in oil burner, installing an external oil-gas dual-fuel burner; sealing the connection between the air duct and the original interlayer air chamber, and connecting the air duct to the external oil-gas dual-fuel burner; Fill the original interlayer air chamber with insulation material. The modification method of the invention is simple, easy to operate, and saves resources.

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...
