Industrial boiler systems – Popular types of industrial boilers

Industrial boilers are also known as Steam Boilers (English: Steam Boiler). Industrial boilers are also known as Steam Boilers (English: Steam Boiler). Normally, the raw materials used by industrial boiler systems are coal, firewood, rice husks, oil, gas, etc. Used to boil water to create hot steam at high temperature and high pressure. Depending on the industry, different amounts of heat energy will be consumed. Let’s find out with GDP Group through this article.

What is an industrial boiler?

An industrial boiler, also known as a boiler, is a device that uses combustion fuel to boil water to form steam. The heat generated is used in many fields and factories, typically: drying, dyeing, cooking, running turbines…

Industrial boilers can push the pressure much higher than pressure cookers. It is an important equipment, applied to most key industries in the country. Plays an important role in providing heat and steam for mechanical systems that need to use steam.

Depending on the type of boiler, people can use different types of fuel for the combustion process such as solids (coal, wood..), liquids (oil..), gases (gas). Let’s learn about popular types of industrial boilers below.

Classification of industrial boilers

Industrial boilers currently provide steam with two most commonly mentioned types: industrial saturated steam and superheated steam. Industrial saturated steam boilers are widely used in processing and manufacturing industries such as  textile factories, sugar factories, chemical factories, alcohol and beverage factories , food and poultry feed factory,…

Superheated steam industrial boilers are widely used in thermal power plants that use steam turbines to operate generators.

Industrial electric boiler

Suitable capacity: 36kw – 720 kw

The advantages of electric boilers are convenience, ease of operation and safety. The disadvantage is that the investment cost of the 3-phase electrical system is high and the heating system is easily damaged by water quality if the input water is not well treated. Dong Anh pressure equipment industrial electric boilers are specifically designed for larger heating systems, are sturdy and easy to maintain when needed, helping to increase equipment life, reduce depreciation costs and production costs. every year for businesses.

The boiler burns sawdust and small fluidized bed pellets

Suitable capacity: 3000 kg/h – 8,000 kg/h

This type of boiler still uses the same combustion chamber as the static grate but differs in the small conveyor belt feeding mechanism and the injection mushroom grate. Raw materials suitable for conveyor belts are in small forms such as finger pellets, loose sawdust; Other large ingredients can be fed into the large combustion door on the front of the boiler.

Depending on the design of each manufacturer, boiler efficiency will be completely different in terms of longevity, fuel savings, fuel diversity during operation, maintenance and repair time, and good pressure retention when operating. stop feeding… Dong Anh pressure equipment equipped for this type of boiler is configured with 5 hot air passes instead of the common 3 hot air passes on the market. This helps customers save fuel and increase equipment durability.

Biomass fired boiler

Suitable capacity: 4000 kg/h – 20,000 kg/h

Fluidized bed boiler is known as the KING of boilers. Large fluidized bed boiler manufactured by Dong Anh pressure equipment has the latest round-cornered combustion chamber design in 2024. The main body of the boiler is equipped with the latest 6-pass hot air technology to help save raw materials and reduce heat. Hot smoke level up to 6 levels, thereby increasing the lifespan of installed equipment. Raw materials suitable for conveyor belts are in small forms such as finger pellets, loose sawdust; Other large ingredients can be fed into the large combustion door on the front of the boiler.

Depending on the design of each manufacturer, boiler efficiency will be completely different in terms of longevity, fuel savings, fuel diversity during operation, maintenance and repair time, and good pressure retention when operating. stop feeding… Currently on the market, there are many suppliers using small fluidized bed boilers (in section 3.2) called “fluidized bed boilers” for short, causing misunderstandings about the price and quality of their goods. This type of king boiler.

Wood and coal-burning boilers use fixed grate

Suitable capacity: 50 kg/h – 8,000 kg/h

This type of boiler has a manual feeding mechanism, the operator puts coal and firewood through the main combustion door on the front of the boiler. Depending on the design of each manufacturer, boiler efficiency will vary in terms of longevity, fuel economy, fuel diversity during operation, maintenance and repair time, and good pressure retention when supply is stopped. whether…

Vertical oil and gas fired boiler

Suitable capacity: 100 kg/h – 2000 kg/h

The advantage of this type of material is cleanliness, neatness, and convenience. The cleanliness rate of raw materials gradually increases from oil, LPG gas, and electricity. Vertical boilers have the advantage of extremely fast steam generation, compact installation area, convenient operation, the only drawback is that operating costs are higher than wood and coal burning boilers. Dong Anh pressure equipment’s vertical oil and gas burning boiler has an exclusive polygonal combustion chamber design to increase heat contact, thereby saving oil and gas up to 5% compared to common round combustion chambers.

Horizontal oil and gas fired boiler

Suitable capacity: 500 kg/h – 6000 kg/h

The advantage of the horizontal boiler is steam stability and fuel savings compared to the vertical type due to its larger structure. Dong Anh pressure equipment’s indoor oil and gas fired boiler has a wavy expansion tube design to create an expansion step for the chamber when the temperature is high, thereby reducing equipment damage, ensuring safety for users and users. contributes to saving oil and gas up to 5% compared to the common straight combustion chamber model.
