Manufacturing method of electromagnetic induction steam generator, and steam generator

Abstract

The invention discloses a manufacturing method of an electromagnetic induction steam generator, and the steam generator. The manufacturing method comprises the steps: S1, a structure of the steam generator is constructed, and structure parameters are acquired; S2, according to the constructed structure and the acquired structure parameters, electromagnetic induction heating and heat-transfer processes are solved, temperature field distribution and surface heat flow density of internal components of the steam generator are obtained; S3, the heating efficiency, temperature distribution of the surface of a frame and the average temperature of a control module area and a frequency conversion module area are acquired; and S4, if the three conditions are all met, manufacturing is completed, if at least one of the three conditions is not met, the internal structure of the steam generator is regulated, and S2 is returned. According to the manufacturing method, by regulating the internal structure, the heating efficiency is ensured, the energy loss is reduced, the local high temperature, causing the poor user experience, on the surface of the frame is avoided, a control module and a frequency conversion module work in an allowable temperature range, and operation stability, reliability and safety are improved.

Description

technical field [0001] The invention relates to a steam generator, in particular to a manufacturing method of an electromagnetic induction steam generator and the steam generator. Background technique [0002] At present, most of the industrial low-pressure steam generators on the market use fuel oil heating, coal-fired heating or electric heating tube heating, etc. These traditional heating methods all have problems such as large energy consumption, high operating costs, and environmental pollution. The country actively promotes green, environmentally friendly, high-efficiency and energy-saving forms of new energy, and the increasingly serious problem of smog, these low-efficiency heating methods are gradually being eliminated. Compared with the above-mentioned traditional heating methods, electromagnetic heating steam generators have appeared. Electromagnetic heating steam generators not only solve the problems of low thermal efficiency, high energy consumption, and seriou...

AI Technical Summary

Problems solved by technology

However, existing electromagnetic induction steam generators also have problems such as poor heat dissipation of the steam generator shell, resulting in local high temperature inside, partial metal shell or internal metal structure heating due to electromagnetic induction, and frequency conversion module under high power conditions. Joule heat temperature is too high and the distance between the two tanks is unreasonable, which leads to the decrease of electromagnetic conversion efficiency and other problems, which brings risks to the operation stability and safety of the steam generator, and the energy loss is relatively large
