[0029] Example 2

[0031] The working process of this invention:

[0032] This invention discloses a mobile electrode boiler system that can be moved to any location requiring heating to supply hot water or steam. Before operation, the mobile electrode boiler unit 10 and the mobile water supply and heating unit 20, mounted on the module base frame, are transported to the site of the user requiring heating via vehicle 100. After being securely parked in their respective positions, quick-connect pipes are installed. The user-side demineralized water pipeline is connected to the solution tank of the dosing device 2 and the boiler feedwater pump module 4. The user-side cooling water inlet and outlet are connected to the boiler circulation pump module 5, and the steam outlet of the electric superheater module 6 is connected to the user-side steam pipeline. Then, quick-connect cables are installed, with the user-side high-voltage cable connected to the high-voltage distribution module 3 and the user-side low-voltage cable connected to the low-voltage distribution module 7. Next, the boiler body module 1 is continuously replenished with water via the boiler feedwater pump module 4. Chemicals are added to the boiler body module 1 via the dosing device 2. Finally, the mobile electrode boiler system undergoes a self-test. After the system self-test is completed, the mobile electrode boiler system is started. The boiler body module 1 first heats the user-connected demineralized water into steam, which can be operated in the following two modes:

[0033] a. When the user side requires a supply of superheated steam (see...) Figure 1 The steam generated by the boiler is input into the electric superheater module 6 through the steam pipe 61. The electric superheater module 6 further heats the steam to the superheated steam with the parameters and quality required by the user before it is delivered to the user side for heating.

[0034] b. When the user side requires hot water or saturated steam (see...) Figure 2 The bypass pipe in the electric heating superheater module 6 directly delivers the hot water or saturated steam generated by the boiler body module 1 to the user side. At this time, the heating device of the electric heating superheater module 6 is not working.

[0035] During operation, the mobile electrode boiler system regulates its power output via boiler circulation pump module 5. Cooling water is used to cool the circulation pumps within module 5. After completing the heating task, the mobile electrode boiler system must be shut down, residual water and steam discharged, and the system cleaned and maintained to ensure safety and stability for the next operation.

[0036] It should be noted that in this embodiment, the use of the electrode boiler moving unit 10 and the water supply and heating moving unit 20 as two moving units is only one form. The number of moving units is not limited to two. According to user needs, multiple moving units can be used in combination, and adding other functional moving units is also within the scope of protection of this invention. Furthermore, the arrangement of each moving unit and module in the above embodiment and accompanying drawings is only one form. The rearrangement and combination of each module, or the addition of other modules, all fall within the scope of protection of this invention.

[0037] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
