Description

Technical Field

[0001] The utility model belongs to the technical field of energy conversion and utilization, and particularly relates to a three-purpose combustion device for coal, gas and oil. Background Art

[0002] Most of the early traditional combustion devices were designed for only a single fuel. The fuel could not be replaced or the conversion was inconvenient. They could not fully utilize the cost advantages of different fuels in different regions and time periods, and could not guarantee the stability of supply. In addition, the physical and chemical properties of different fuels vary greatly, and traditional burners cannot fully take into account the optimal combustion conditions of various fuels. With the advancement of combustion theory and control technology, especially the development of atomization technology, premixed combustion technology, and ratio regulation technology, it has become possible to achieve efficient and environmentally friendly combustion of multiple fuels on the same burner device. At the same time, in order to work effectively in different application scenarios, the coal-gasoline three-purpose combustion device must have good compatibility and be able to seamlessly connect to the existing energy supply system and equipment, so as to meet the heat load requirements under different working conditions. In addition, there are potential safety risks in the combustion of coal, gas, and oil, so special attention should be paid to safety protection measures to ensure safety and reliability during operation.
