Description

Technical Field

[0002] Conventional industrial steam rooms currently use two energy sources: natural gas boilers or electricity to generate steam. Natural gas boilers generate steam because steam must be generated from the boiler and then transported to the steam room through steam pipes. In each link of natural gas steam generation and pipeline transportation, 50% of the energy is wasted, and the energy utilization rate is low; the current technology for electric steam generation can only place the electric steam generator outside the steam room. Although the transportation distance of the steam pipeline is shortened, 40% of the energy is still wasted in the process of electric steam generation and steam transportation to the steam room. Whether the traditional steam room is built with refractory bricks or metal insulation composite panels, it cannot solve the problems of gaps between walls, gaps between panels, steam and heat leakage, and the energy thermal efficiency is low, and the energy consumption remains high.

[0003] In addition to high energy consumption, natural gas boilers for steam generation also have the following disadvantages:

[0004] ① It is not conducive to the national trend of carbon neutrality. Boiler combustion will produce much more carbon dioxide than electric energy.
