The boiler is a key device of a hot water system of an experimental platform and is an energy generating device of the hot water system.
Description
The technical field is as follows:
the invention relates to the technical field of boilers, in particular to a subcritical direct-current hot water boiler.
Background art:
the subcritical boiler is mainly used for providing subcritical hot water with required temperature for an experiment platform, is a key device of a hot water system of the experiment platform and is an energy generating device of the hot water system.
At present, hot water boilers at home and abroad are basically 1.6MPa or lower, and the heating requirements of subcritical pressure hot water cannot be met without the hot water boiler under the subcritical pressure (17 MPa).
The invention content is as follows:
the invention provides a subcritical direct-current hot water boiler for overcoming the technical problems, which can meet the heating requirement of subcritical pressure hot water.
The subcritical direct-current hot water boiler comprises a hearth and a flue which are arranged in a boiler body, and the technical scheme adopted for realizing the purpose is as follows: the flue comprises a middle heat exchange flue and a tail heat exchange flue which are sequentially communicated, the middle heat exchange flue is communicated with the furnace chamber, the tail heat exchange flue is communicated with the smoke outlet of the furnace body, the economizer comprises a high-temperature economizer and a low-temperature economizer, the high-temperature economizer is arranged in the middle heat exchange flue, and the low-temperature economizer is arranged in the tail heat exchange flue.
As a further improvement of the invention, a cyclone burner is arranged at the inner top of the furnace body and is positioned above the hearth.
The invention has the beneficial effects that: the invention arranges the middle heat exchange flue and the tail heat exchange flue in the furnace body, arranges the high temperature economizer in the middle heat exchange flue to enable the middle heat exchange flue to form a membrane wall convection heat exchange flue, arranges the low temperature economizer in the tail heat exchange flue, and combines with the model water wall hearth to form a hot water boiler under the subcritical pressure (17 MPa), so as to heat hot water under the subcritical pressure to the temperature parameter required by the industrial experiment and provide the required subcritical hot water for the experiment platform. The boiler is a key device of a hot water system of an experimental platform and is an energy generating device of the hot water system.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention.
As shown in the figure, 1 is a hearth, 2 is a middle heat exchange flue, 3 is a tail heat exchange flue, 4 is a smoke outlet, 5 is a high-temperature economizer, and 6 is a low-temperature economizer.
The specific implementation mode is as follows:
the following detailed description of specific embodiments of the invention, taken in conjunction with the accompanying drawings, will be readily understood and appreciated by those skilled in the art as the same becomes better understood and appreciated:
the subcritical direct-current hot water boiler comprises a hearth 1 and a flue which are arranged in a boiler body, wherein the flue comprises a middle heat exchange flue 2 and a tail heat exchange flue 3 which are sequentially communicated, the middle heat exchange flue 2 is communicated with the hearth 1, the tail heat exchange flue 3 is communicated with a smoke outlet 4 of the boiler body, the economizer comprises a high-temperature economizer 5 and a low-temperature economizer 6, the high-temperature economizer 5 is arranged in the middle heat exchange flue 2, so that the middle heat exchange flue 2 forms a membrane type water wall convection heat exchange flue, and the low-temperature economizer 6 is arranged in the tail heat exchange flue 3.
Furthermore, two cyclone burners 7 are arranged at the top of the hearth 1, and natural gas is ignited through the cyclone burners 7, so that the boiler can use the natural gas as fuel, and the boiler is more convenient and faster to use. In addition, natural gas is adopted as fuel, dust cannot be generated, so that ash removal equipment does not need to be arranged for the boiler, the structure of the boiler is simplified, and the manufacturing cost is saved.
Flue gas flow: the two cyclone burners 7 are arranged at the inner top of the furnace body and above the hearth 1, after the natural gas is ignited, the generated flue gas enters the membrane wall convection heat exchange flue after heat exchange from top to bottom, flows into the tail heat exchange flue 3 after heat exchange of the high-temperature economizer 5 in the middle heat exchange flue 2, and is discharged out of the furnace body through the smoke outlet 4 after heat exchange of the low-temperature economizer 6 in the tail heat exchange flue 3.
Water flow: the backwater enters an inlet header of a low-temperature economizer 5, enters an outlet header of the low-temperature economizer 5 after heat exchange of the low-temperature economizer 5, enters a water-cooled wall distribution header through a connecting pipe, is respectively introduced into a side water-cooled wall lower header and a water-cooled wall middle lower header through a connecting pipe, so that the water respectively enters two side water-cooled wall upper headers and a water-cooled wall middle upper header after heat exchange of a membrane water-cooled wall formed by the high-temperature economizer 6, finally is collected into a collection box through the connecting pipe, and is led out of the furnace.
The above is a specific embodiment of the present invention, and it should be noted that the specific embodiment is not to be construed as limiting the scope of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
