How is secondary steam pressurization achieved
Thread Content
The customer’s factory uses steam supplied by a thermal power plant; due to the long transmission distance and numerous units that draw steam along the way, the pressure of the steam upon arrival at the factory does not meet the required standards. The operating pressure of the equipment is 0.5 Mpa. Current measurements show that the steam pressure is on average 0.4 Mpa in summer and 0.25 Mpa in winter. These conditions do not meet the requirements! ! ! The factory cannot operate gas boilers, coal boilers, oil boilers, or electric boilers on its own. It is possible to use industrial electricity; power consumption is not a concern ； At present, only meeting the equipment usage standards is considered. Is there any good way to solve this? Or are there any existing devices that can re-pressurize the steam to meet the operational standards?
Talk to the thermal power plant to see if it’s possible to increase the pressure supplied from the power station. If that’s not possible, it will be necessary to identify which section of the pipeline has the greatest pressure loss, and then expand the diameter of that section.
The factory is so frustrated by this whole situation that it has no patience left; it can’t deal with the thermal power plant because those people have strong backing.
This general solution is to increase the pressure at the power plant outlet, or to enlarge the diameter of the main pipe. If you want to do it yourself, go with a steam compressor, but it’s expensive and not cost-effective at all. It’s better to use a gas stove instead, as it doesn’t require steam from a power plant.
The plan upstairs is feasible. It’s not cost-effective to do it by yourself!
Yes, overall, it is more appropriate to install a small steam generator on the equipment side, as the technology is mature. If the pressure is sufficient, use pipeline steam ； If the pressure is insufficient, steam from a steam generator is used. Like!
A friend told me that Spishack in the UK has a steam drum with electric heating for assisted pressurization, which can achieve secondary pressurization. But the market price is over 1 million, so it really isn’t cost-effective.
The cheapest solution: the power plant increases the transmission pressure
The simplest solution is to use a steam compressor, but it is relatively expensive.
