High-Pressure Boilers and Low-Pressure Boilers

The working pressure of the boiler can be divided into high-pressure boilers and low-pressure boiler industrial steam boilers, both are used to produce steam equipment, but there is a clear difference.

High-pressure boilers and low-pressure boilers differ in the pressure they can withstand when in use. High-pressure boilers are generally able to reach steam pressures of more than 3MPa, while low-pressure boilers can usually only reach less than 2Mpa.

High-pressure boilers and low-pressure boilers also differ in their construction. Due to the need to withstand higher temperatures and pressures, high-pressure boilers are usually made of steel and have a more complex and rigorous structural design. Low-pressure boilers, by contrast, have less stringent material requirements and are usually made of iron or copper.

There is also a clear difference between high and low-pressure boilers in terms of use. High-pressure boilers are usually used in industrial production that requires high-temperature and high-pressure steam, such as the power generation process in power plants, chemical plants, chemical production, etc. Low-pressure boilers are mainly used for general heating and hot water supply, as well as some industrial processes that do not require high temperatures, such as heating and hot water supply in buildings, schools, and hotels, as well as hot water demand in food processing, washing, and other fields.

Both types of boilers are very important in terms of the industries they serve. High-pressure boilers mainly serve the industrial sector, such as power generation, chemical, pharmaceutical, textile, paper, and other production processes that require large quantities of high-temperature and high-pressure steam. Low-pressure boilers mainly serve the commercial and civil sectors, such as heating and hot water supply in buildings, schools, hospitals, hotels, etc., and hot water demand in the fields of food processing, washing, and automobile washing.

Modular Boiler

The introduction of modular boiler design ideas makes the boiler system better able to adapt to the needs of enterprises at different stages of development, whether it is the increase or decrease of production capacity or technological upgrades, which can be realized through the addition, deletion, or replacement of modules.

FAQ

What is the main difference between a fire tube boiler and a water tube boiler?

The main differences between fire tube boilers and water tube boilers are reflected in the following aspects:

First, their principles and structures are different. In a fire tube boiler, the flue gas produced by the combustion of fuel flows through the fire tube or flue tube, heating the water, vapor, or vapor-water mixture outside the fire tube or flue tube. Water tube boilers, on the other hand, have combustion chambers and heating surfaces on the outside of the boiler tube, with water and vapor flowing inside the tube. This structural difference makes the steam generated on the heating surface of the water tube boiler be flushed away immediately, improving the heat absorption rate of the pot water.

Secondly, their performance characteristics and areas of use are also different. Fire tube boilers are relatively inefficient due to their structural characteristics and are usually used for users with small capacities. Water tube boilers, on the other hand, are suitable for high-pressure, high-temperature situations, such as electric power, chemical industry, and aviation.

How does the choice of fuel affect the efficiency of an industrial boiler?

The choice of fuel has a significant impact on the efficiency of industrial boilers. Commonly used fuels include natural gas, oil, coal, and biomass. Among them, natural gas, as a clean, efficient, and conveniently available fuel, can be used with an efficiency of more than 90%. In contrast, traditional fuels such as coal-fired may lead to lower boiler efficiency and environmental pollution due to problems such as insufficient combustion and improper treatment of emissions. Therefore, when choosing a fuel, factors such as the structural characteristics of the boiler, combustion method, quality control and price need to be considered to achieve the best energy efficiency and environmental protection.

What maintenance must be carried out on industrial boilers?

Industrial boilers must undergo a series of maintenance tasks to ensure their safe and efficient operation. These maintenance tasks include:

Regular maintenance of the boiler, including cleaning, descaling, and lubrication to keep the boiler clean and in good condition.

Inspecting key boiler components such as burners, water level gauges, safety valves, etc., to ensure their proper operation, and dealing with any problems found promptly.

Manage the fuel to ensure the cleanliness and quality of the fuel, and avoid using inferior fuel to damage the boiler.

Pay attention to industry dynamics, introduce new technologies and methods in time, and technically upgrade the boiler to improve its performance and service life.
