Q：Can a steam generator explode?

A：We know that there are potential safety hazards in boilers, and most boilers are special equipment that need to be inspected and reported annually. Why say most of it instead of absolute? There is a limit here, the water capacity is 30L. The “Special Equipment Safety Law” stipulates that the water capacity is greater than or equal to 30L, which belongs to special equipment. If the water volume is less than 30L, it does not belong to special equipment, and the state exempts it from supervision and inspection, but it does not mean that if the water volume is small, it will not explode, and there will be no safety risks.
A steam generator is a mechanical device that uses heat energy from fuel or other energy sources to heat water into hot water or steam. At present, there are two working principles of steam generators on the market to generate steam. One is to heat the inner pot, that is, “water storage-heating-water boiling-output steam”, that is, the boiler. One is direct-flow steam, which heats the pipeline through the exhaust smoke, and the water flow through the pipeline is instantly atomized and vaporized to generate steam without the need for water storage. We call it a new type of steam generator.

Then we can be very clear that whether the steam generator will explode depends on the structure of the corresponding steam equipment. The most distinctive thing is whether there is an inner pot and whether it needs to store water.
There is an inner pot body, if it is necessary to heat the inner pot to generate steam, it will operate in a closed pressure environment. When the temperature, pressure and vapor volume exceed critical values, there is a risk of explosion. According to calculations, once the steam boiler explodes, the energy released per 100 kilograms of water is equivalent to 1 kilogram of TNT explosives, and the explosion power is huge.
The internal structure of the new steam generator, the water flowing through the pipe is vaporized instantly, and the vaporized steam is continuously output in the open pipe. There was hardly any water in the pipes. Its steam generation principle is completely different from that of conventional boiling water. , there is no explosion condition. Therefore, the new steam generator can be extremely safe, there is absolutely no risk of explosion. It is not unreasonable to let there be no explosive boilers in the world, and it is achievable.
The development of science and technology, technological innovation, and the development of steam thermal energy equipment are also making continuous progress. The birth of any new type of equipment is the product of market progress and development. Under the market demand of energy saving and environmental protection, the advantages of the new steam generator will also replace the backward traditional steam equipment market, drive the market to develop more benignly, and provide more guarantee for the production of enterprises!
