High Pressure Steam Boiler – The Complete FAQ  Guide

High pressure steam boiler are the most important part of different industries. Let us first understand how these machines work and know the necessary information about them before purchasing.

The following are answers to frequently asked questions about high pressure steam boiler.

What Is A High Pressure Steam Boiler and High Pressure Steam Boiler System?

A high pressure steam boiler can produce higher pressures and temperatures compared to conventional boilers.

High Pressure Steam Boiler is used to generate enough heat to create the necessary pressure for producing power. The water that boils or turns into vapor then spins turbines in a turbine generator.

A high pressure steam boiler can be utilized for applications like power generation, food processing, and oil refining. These high pressure steam boiler have been popular since the late 1800s because of their greater efficiency compared to conventional boilers.

How Does A High Pressure Steam Boiler Work?

A piston or turbine moves the boiling water to generate pressure. This pushes down on a column of liquid and creates motion. This movement has an arrangement of pipes attached to it, which hold the rotating arms for the workforce in factories.

The steam from high pressure steam boiler is then fed into a condenser, cooled, and turned back to liquid form. This allows the process to start over again. The condensed water then travels from the boiler through pipe coils called headers.

The headers of high pressure steam boiler are attached to create one large column of cold water. This creates a more efficient distribution of heat, which helps to manage the temperature.

What Are Some Types Of High Pressure Boiler

La Mont Boiler:

Lamont boilers are forced convection water tube boilers that use a pump to circulate water. With its economizer, it can use less energy and increase efficiency. It also has a boiler drum, evaporator, superheater, and air heater.

Lamont boiler high pressure steam boiler

Benson Boiler:

Unlike the La Mont boiler, the Benson boiler does not have a steam separator and operates under critical pressure. A forced circulation water tube prevents bubbles in it by compressing the feed water to extremely high pressure.

The compressed water feed makes the water as dense as the steam. This reduces the latent heat in the water to zero, making steam generation easier.

Benson Boiler high pressure steam boiler

Loeffler Boiler:

As a result of the poor heat transfer achieved by the La Mont boiler, the Loeffler boiler was developed. Its water tube circulates water under high pressure, as it does in a Benson boiler.

Loeffler Boiler high pressure steam boiler

Radiant and convective superheaters work together to distribute steam to the turbine in the Loeffler boiler. By burning fuel, thermal energy heats the saturated steam. After passing through the convection superheater, the steam is further heated by the flue gases before passing to the turbine.

Velox Boiler:

In a Velox boiler, high velocity is used to create steam quickly through forced circulation. With Velox boilers, heat is transferred quickly because the gas moves faster than the speed of sound.

Velox Boiler high pressure steam boiler

Velox boilers use gas turbine compressors to send compressed air into the combustion chamber, where more heat is released. Flue gas velocity is then accelerated to the speed of sound due to the increased heat release rate.

What Are The Benefits Of Using Your High Pressure Steam Boiler?

Yongxing High pressure steam boiler are high efficiency and excellent to generate a lot of energy. This makes high pressure steam boiler perfect devices for factories that rely on high temperatures or heavy machinery.

The forced circulation of water in high pressure boiler increases evaporation capacity and promotes positive circulation of water. This means that these boilers are more efficient in heating and inducing a higher rate of evaporation to create steam.

For high pressure steam boiler,it also has reduced condensation rates when exposed to cold ambient air, meaning they can operate at lower temperatures. This means high pressure steam boiler is able to provide heat during the colder months without having to use an excessive amount of fuel.

Additionally, your high pressure steam boiler uses steam more than 100℃ to heat the water, so all parts of the boiler are heated uniformly.

Why Is My High Steam Boiler Pressure?

 This could be because there is too much water in the bottom of your tank. We recommend contacting a professional for assistance if you have any problems about fixing this problem yourself.

Another reason might be because the safety relief valve isn’t working properly. It will need to be shut off and repaired as soon as possible if it is operating at high pressure.


What Is A Boiler Flue?

 A flue of high pressure steam boiler is the section of pipe that connects a furnace to your chimney or vent. They are typically made out of steel and can be insulated with fiberglass, aluminum, and other materials for better efficiency.

Heating water, high pressure steam boiler is ok to burn fuels such as gas and light oil, creating some harmful byproducts like carbon monoxide. These by-products are emitted outside your building through the high pressure steam boiler’s flue.

Why Is My High Pressure Steam Boiler Turning On When It Shouldn’t?

 There may be some issues with the thermostat or pressure relief valve inside it. You will need to have these repaired as soon as possible before something else goes wrong.

Does Boiler Pressure Go Up When Heating Is On?

Yes. This is because hot water vaporizes and expands more in a pressurized boiler, thus increasing its volume and consequently pushing down on the piston that creates the steam to power your building’s radiators.

What Is the Difference Of High PressureSteam Boiler VS Low Pressure Steam Boiler?

1. In high pressure steam boiler, the heating pressure passes 15 psi, and boiler furnace temperature inside can go over 121 °C. These boilers operate at high pressure, so it is important to ensure safety at all times.

Yongxing high pressure steam boiler could get to 350psi and 554psi, help you to achieve high temperature superheated steam.

The worker who does the high pressure steam boiler operation must regularly check the pressure gauge, safety valve, alarm system, switches, leaks and etc. Any malfunctions must be fixed immediately to prevent further damage.


2. While in the low pressure boiler,  its pressure keeps under 15 psi. Highest process pressure less than 260 psi. In addition, the temperature in a low-pressure boiler will not rise above 121 °C.

For this reason, these types of boilers do not need to be checked as often as the high pressure steam boiler.

Yongxing suggests you our low pressure steam boiler generator LHG or LHS. The working pressure at 13PSI. It is very safe and easy to install, with no need for inspection.

How to choose between a low-pressure steam boiler and a high pressure steam boiler?

Your choice should be dependent on your needs in the process.

For example, if your steam boiler process is simple and wants steam only as a tool for conveying heat, so you will only need a low-pressure steam boiler in the process. Such as our vertical small steam boiler or steam generator.

While, if the heat required has to be met using a high pressure steam boiler, you must choose the high pressure steam boiler system since only it can correctly contribute to your work.

What Should I Considering When I Choose A High Pressure Steam Boiler System?

The only issue at hand is finding which high-pressure steam boiler will take care of steam boiler psi. Here are some tips to help make choosing the right high pressure steam boiler system easier:

  1. Have enough steam boiler psi 

Steam pressure measure by psi, bars, or Mpa. For a high steam boiler system, we design at least three bars (0.3Mpa). The reason why we use is that we required to supply your production line effectively clean steam.

Yongxing takes the first importance to ensure that the high pressure steam boiler pressure is maintained rather than emitted in waves. Otherwise, the steam will not be as effective as it should be.

 2. High pressure steam boiler accessories

The boiler accessories needed to depend upon your factory. Yongxing engineering suggests you prepare at least one year of boiler parts to ensure that once required. They are always there.

Don’t look down on these high pressure steam boiler accessories. If you can replace them on time, they can help you save a lot of money and maintenance effort. Yongxing is willing to supply you with high pressure steam boiler parts anytime at our best factory price.

  3. Check the size of the package.

Yongxing dedicates to making all the high pressure steam boiler into small packages. They are explicitly designed to down the shipping cost purposes, while our high-pressure steam boiler also proves to be significant water content, enough steam output, less raw materials cost.

 4. Look at the construction quality

The boiler drum and pipes determine the life span of the high pressure steam boiler, so Yongxing ensures it makes special boiler steels 20g. The high pressure steam boiler main parts are tough enough to endure bumps and scrapes. 

How Hot Is High-Pressure Steam?

High-pressure steam temperatures would rise from 121°C up to 648°C.

Do Some Boilers Require A Water Line?

 Some high pressure steam boiler do not need a line. They can still operate without this feature once you have a supply of water on hand.

What Are The Main Tasks Of High Pressure Steam Boiler Operators?

If you are a high pressure steam boiler operator, it is your responsibility to:

  • Regularly inspect switches, valves, and safety devices
  • Beon the lookout for leaks or problems
  • Prevent further damage by fixing problems immediately
  • Prevent corrosion and scale in the boiler by maintaining the proper chemistry

How Can I Confirm If My Boiler Is Leaking?

If you notice any water coming out of the boiler or around it, this means there is a leak. Look for signs of wet spots on your playground and dripping pipes to locate where the problem may be occurring. Once found, contact professionals right away as these leaks are usually serious.

How Can I Detect Missing Insulation?

Missing insulation may not be visible, A better way to detect it is using a thermal imager. You can get it from a plumber or other professional if your building doesn’t have one.

What Should I Do When The Tank Is Not In A Firing Sequence?

Drain the tank for a few seconds to test the float chamber. If the water level is low, the system should automatically activate.

How Often Should I Have My Heating System Checked?

A high-pressure boiler system should be checked at least once a year. In the event of an emergency, it is recommended that you contact our company as soon as possible.

What Common Problems Do High Pressure Steam Boiler Have?

● Irregular or infrequent maintenance

Problems with boilers are often caused by inadequate maintenance. A lack of inspection can result in minor problems being overlooked, which creates worse problems in the future.

Reminder: the cost of regular maintenance is dramatically lower than the time and profit lost due to a broken boiler.

● Missing Insulation

The efficiency of the high pressure steam boiler system is reduced when there is no insulation. Insulation helps keep heat in the system. When the heat dissipates, more fuel is required to maintain the proper temperature and pressure.

When your energy bills rise without your boiler use increasing, the system may be lacking insulation. We recommend calling a technician to inspect it.

● Water and Safety Probes Breaking

Like pipes, probes submerged in water can become encrusted with scale. One of the reasons to treat your tank water is due to this coating on probes.

The high pressure steam boiler may automatically shut off if the probes cannot accurately measure the water temperature or pressure. Meanwhile, a faulty safety control or sensor could also prevent the boiler from shutting itself off in an emergency.

● Random Shutdowns

In case of a malfunction, the heating system automatically turns itself off. Never try to restart the system on your own if the system shuts down for safety reasons. This could result in devastating consequences for you and those nearby.

● Slow Pressure Build

In most cases,If your system has a leak of pressure, the pressure data will going down.  A leaky steam pipe prevents the system from working in stable pressure.

It is best to begin your inspection by checking all valves. These places are likely to suffer from small, unseen holes that could alter the pressure.
