Description

Technical Field

[0001] The utility model relates to the technical field of boilers, in particular to an energy-saving device for a coal-fired and gas-fired dual-purpose boiler. Background Art

[0002] Most of the existing boilers adopt a single fuel design. For example, a boiler that uses gas as fuel must be equipped with a burner. At the same time, it does not have the facilities such as grates, coal filling ports and ash removal doors required by coal-fired boilers, and cannot use coal as fuel. Boilers that use coal as fuel do not have the sealing, safety control and other equipment requirements required for gas boilers. Therefore, coal-fired boilers are even less suitable for using gas with strong evaporative properties as fuel. In view of the current requirements for environmental protection when using boilers, the research and development of environmentally friendly boilers that can use both gas and coal as fuel is a trend in the development of boiler technology. In view of the above problems, there may already be technical means to solve them in the existing technology, but this case intends to provide an alternative or replacement technical solution.
