Is it better to use steam or electric heating to heat hydrogen to 150 degrees? Can 1MPa saturated steam be used for this purpose? Thank you!
Electric heaters are better; nowadays, higher-quality electric heaters offer excellent performance and can be used for heating hydrogen. Steam heating is difficult to control
Thank you. Do you have any information on manufacturers of better electric heaters?
Hydrogen is heated to 150 degrees using steam, and this can be achieved with saturated steam at 1 MPa. The temperature is higher than 150°
But it was said upstairs that steam is hard to control – what’s your opinion?
Hydrogen is an explosive substance; electric heating is not safe, while steam heating is safe and reliable. Steam at 1 MPa has a temperature of 180 degrees, which is sufficient to meet the heating requirements of 150 degrees. Steam can be controlled by the pressure in the steam drum or buffer tank.
I wonder if there are any projects that have used steam to heat hydrogen to 150°C or higher?
There are many such operating conditions; by installing a steam coil with a certain heat exchange area inside the hydrogen buffer tank, it is possible to heat the hydrogen contained within the tank.
Steam heating is fine; electric heating is more suitable for temperatures above 300°C
It depends on the amount used: electric heating is convenient for small quantities, while steam is cheaper for larger amounts. It’s difficult to generate steam at temperatures above 300 degrees; I use steam with a flow rate of 6 cubic meters per hour at 600°C, powered by electric heating
My unit is small, with a capacity of around 0.5 m3/h. It uses hydrogen gas, at a relatively high pressure of about 7 MPa and a temperature of 150 degrees. I plan to use saturated steam at 1 MPa for heating; I think this is safer than electric heating. What do you think?
