You’ll also be able to compare it with the steam boilers and know how they differ. We’ll end the discussion with the best electric steam generator prices to help you pick the best for your business. Now, without further ado, let’s get started.

What is an Electric Steam Generator?

A steam generator is a low-water-content boiler similar to a flash steam boiler. The standard design consists of a single coil of a spiral water tube, often known as a monotube.

Like a forced-circulation boiler, the circulation is only performed once and pushed under pressure. Even when run at high pressures, they are safe from explosions because of their narrow-tube construction and lack of large-diameter drums or tanks. 

Depending on how much steam is required, the pump flow rate may need to be modified. The burner output is throttled to maintain the working temperature. The burner output required varies based on the amount of water being evaporated. This can be adjusted through closed-loop control, maintaining a set temperature, or open-loop control, changing with the pump’s flow rate.

Working Principles of an Electric Steam Generator

Working Principles of an Electric Steam Generator

We can divide the working principles into three main parts. These are the following.

1. Heat Transfer

We generate heat energy in various activities, which we can convert into more useful forms like mechanical and electrical energy using an electric steam boiler. Initially, we clean up this heat because it’s often not pure.

For instance, the heat comes from radioactive fuel in a nuclear power plant. To clean it, we use a heat exchanger. Here, we heat another substance, like a special fluid, that doesn’t harm the water and use that heated fluid to warm up clean water.

2. Steam Generation

To produce steam, we pump the heated fluid through a water bath. It doesn’t matter how the pipes are arranged; the idea is the same. We want the heated liquid to touch the water as much as possible to heat it quickly and create steam. In modern nuclear and coal power plants, we often make steam at extremely high temperatures and pressures.

3. Conversion of Heat to Electricity

Supercritical steam has a lot of energy. We push this superheated fluid through a turbine with many blades. The high pressure of the liquid makes these blades spin, which turns a shaft. We use the energy from this spinning shaft to generate electricity using an electrical generator.

Electric Steam Generator Main Components

Having understood its workings, let’s now understand the main components of commercial electric boilers.

1. Electric heating element or coil

Its primary role is to transform electrical energy into heat energy. This generated heat is the essential ingredient for producing steam.

2. Water tank

Think of the water tank as the heart of the steam generator. Like a wood fired steam boiler, it functions as a storage reservoir for water. This stored water is gradually heated by the heating element, eventually turning into steam.

3. Pressure gauge

The pressure gauge serves as the generator’s “pressure meter.” The pressure gauge constantly monitors and displays the internal pressure of the steam generator. This information is vital for ensuring a safe and effective operation.

4. Safety valve

Safety valves are the guardians of safety within the steam generator. If the pressure inside the generator exceeds safe levels, these valves automatically open to release excess steam. This critical function prevents the pressure from building to dangerous levels and safeguards against potential accidents.

5. Control panel

Consider the control panel as the nerve center of the steam generator. It contains buttons, switches, and displays that allow operators to control and adjust various parameters. These parameters include temperature, pressure, and other essential settings for desired steam production.

6. Steam outlet

The steam outlet is where the real action happens. Once the water inside the generator transforms into steam, it’s channeled through the steam outlet. From there, it’s directed to various applications that rely on steam, such as industrial processes, heating systems, or power generation.

What’s the Difference Between Electric Steam Generator And Steam Boiler?

Before we understand the difference, let’s get your mind clear on what a steam boiler is.

A steam boiler is a type of energy conversion device. Chemical energy from the fuel, electrical energy, thermal energy from high-temperature flue gas, etc., are all energy sources fed into the boiler. After being converted by the boiler, it produces steam and hot water with a specific amount of heat energy. 

Here, the steam can be produced from the water and used to power turbines or other machinery. Although more common in industrial settings than residential ones, steam boilers can heat houses and generate power.

Now, getting back to the discussion.

Difference Between Electric Steam Generator And Steam Boiler

Industrial steam generator and industrial electric steam boilers do the same job—they make steam. But here’s how they’re different:

Steam Generators:

  • Imagine a single, big tube that heats water to produce steam.
  • They’re smaller, start up faster, and need less maintenance because of their design.
  •  They’re like a speedy microwave, quickly heating your food when needed.

Steam Boilers:

  • Think of lots of smaller tubes heating water to make steam.
  • They take more time to start up and are better at continuously making a lot of steam, like a giant factory machine that keeps running all day.

So, if you want steam in a hurry and only as much as you need, go for a steam generator. But a steam boiler is your go-to if you need a constant steam supply.

Why Use a Steam Generator Over a Steam Boiler?

Industrial electric steam generators and steam boilers serve different purposes. Yet, there are a lot of reasons that make electric steam generators superior. Let’s take a look at them.

1.   Energy-Efficiency

Electric steam generators are good at using energy efficiently. They don’t use power when they’re not making steam. This is especially useful in the warmer months when you don’t need a lot of steam.

On the other hand, fuel-fired boilers always need a lot of energy, even when you don’t need much steam. Even turning them on and off is more challenging and inefficient.

2.   Safety

Electric steam generators are safer because they don’t use flammable fuels. This makes them much less likely to have serious problems, like hazardous accidents.

However, these issues in fuel-fired boilers happen frequently. These include not having enough heat, not treating the water properly, creating a vacuum, flame troubles, and even explosions.

3.   Portability 

Unlike big boilers with special rooms and long pipes, electric steam generators are small and only need a little space. This is a big plus, especially when you only have a little room to work with. It’s helpful in tight places where you need to make the most of every bit of space.

And, because you don’t need a whole special room just for them and don’t have to deal with complicated pipes, these electric steam generators save you money. Meanwhile, you spend less on building and running an extensive boiler system. So, it’s not just space you save; it’s also your wallet!

That brings us to the next point: 

4.   Cost- Effective

Setting up an extensive fuel-fired boiler system takes time and money. In contrast, electric steam generators are way more budget-friendly. They’re great for jobs that don’t need as much steam as those big boilers produce. So, you save money and still get the steam you need without all the hassle and expense of a vast system.

5.   Quicker to Start

Electric steam generators can start making steam in a few minutes, even if they are not warmed. In contrast, traditional boilers can be slow and may take hours to get going.

Because electric steam generators are so fast, they’re excellent for situations where you need steam urgently. This might happen during emergencies, in labs, or when you’re testing processes. Their quick response can be a real lifesaver in these kinds of situations.

Electric Steam Boiler Price Range

Due to their smaller size, electric steam generators are usually more budget-friendly than steam boilers. The starting price of these generators is $1200 and can go up to $100000. However, when looking for high-end generators, be prepared to spend $5000 or even more.

Final Thoughts

In a nutshell, electric steam generators are a smart choice. They’re efficient, safe, and pocket-friendly compared to steam boilers. They start quickly, making them perfect for emergencies or urgent steam needs. Plus, they save energy and space, making them a versatile option.

Even if you look at the price, you can get an excellent electric steam generator for as little as $1200. However, make sure to do your research before spending your money.
