A low-pressure steam train steam pressurization pump – how can a pump generate steam? A steam compressor can be considered to compress the low-pressure steam to 3.0 Mpa; otherwise, it will be necessary to install new coal-fired, oil-fired, gas-fired, or electric heating boilers capable of operating at 3.0 Mpa.

Low-pressure steam becomes condensate as soon as it is pressurized (gases can be pressurized using compressors, but steam turns into water once pressurized). Steam can have its pressure reduced from high to low, but not increased from low to high. If steam is still needed after raising the pressure from low to high, then heating measures must be added in between. If it’s feasible upstairs, other methods can also be used; it is recommended to employ electric heating, or media such as electrically heated molten salts or heat transfer oils, and use these to provide heat.
Just use multi-stage feed water pumps to increase the pressure of the feed water.
Steam at 3.0 Mpa needs to reach temperatures of over 230 degrees; simply compressing low-pressure steam will only result in water. Use a boiler – the fuel type depends on the specific circumstances.
Thank you all for your attention. I can’t find information on small high-pressure boilers. I’ve seen data on low-pressure superheated steam that is pressurized using steam pressure pumps, but that’s not enough...
Reply 1# pzhmotor: It is used for pneumatic grinding of solids – why not use a compressor instead?

In the industrial production of post-treatment for rutile titanium dioxide, pneumatic grinding is usually carried out using medium-pressure steam (around 2.2 Mpa), and this is also the case with most equipment abroad (as far as I know). I think that even if high-pressure gas could be used for crushing, steam would still be the preferred option, as the associated sulfuric acid plants have waste heat boilers that can generate medium-pressure steam, resulting in significantly lower costs overall. The post above mine is incorrect; it’s not a series pump, but a series steam compressor.
In your case, the only option is to have a special boiler manufactured on order. It would be best if it’s located near a factory, as there the waste heat can be recovered, which helps reduce costs. Other methods are not very economical.
If the boiler cannot do it, it is recommended to break down the process to achieve the same result. It’s just an idea; I’m not sure if it will work! First, generate saturated steam through pressurized injection, followed by a high-temperature heat exchange unit at the rear end
Rather than having a custom boiler, it is better to obtain medium-pressure steam from an external source (if there is a power plant nearby) and add a temperature and pressure reducing valve
