Gas boiler structure:

   Hekuo gas boilers are currently mainly available in the following types:WNSSeriesSZSSeries.WNSThe series of boilers are mainly composed of two major components: the drum and the furnace body. They feature a second and third return螺纹烟管 heating surface, also known as horizontal three-return boilers. What is meant by...“Wet Back” Boilers refer to the smoke chamber of the boiler being moved inside the drum, where the tube plate, back plate, and cylinder of the smoke chamber are all surrounded by boiler water.(Immersed in furnace water)Therefore, it is referred to as“Wet-back style”(Also known as water-backed style)。
   CurrentlyWNSAll the regenerative chambers in the series are submerged in water, making them wet-back boilers. The dry-back boilers do not have a full enclosure in water. The He Guo gas boilers use a wet-back structure. Additionally, to ensure the safe and economic operation of the boiler, auxiliary equipment such as instruments, automatic control systems, and protection systems are also added.

    SZSThe series of boilers belong to the double-drum longitudinal chambered fire-tube boilers. These boilers are of the type with water-cooled walls, featuring upper and lower drums connected by a downcomer and water-cooled wall tubes, forming the framework of the combustion chamber.

Fuel boiler

Post-World War II, with oil prices low, many countries began widely using oil-fired boilers. These boilers were easily automated. After the oil price hike in the 1970s, many countries reverted to using coal resources. At this time, the capacity of power plant boilers also increased, demanding combustion equipment that not only burns completely and ignites stably, operates reliably, and has good low-load performance, but also reduces pollutants in the flue gas.

In coal-fired (especially lignite-fired) power plant boilers, the use of staged combustion or low-temperature combustion technology, such as delaying the mixing of coal powder with air or adding flue gas to the air to slow down combustion, or dispersing burners to control furnace temperature, not only inhibits the formation of nitrogen oxides but also reduces slagging. Boiling combustion, which is a type of low-temperature combustion, can not only burn solid fuels with very high combustible ash content but also add limestone to the boiling bed for desulfurization.

Gas boiler

Boilers once symbolized the industrial age, but with time, these relics of the old industrial era struggle to fully meet the demands of modern businesses. So, what should boiler companies plagued by diseases do? Gas boilers can help you solve the issue!

Generally, common issues with boilers include being costly, environmentally unfriendly, posing high safety risks, requiring dedicated management due to space consumption, and being麻烦 to operate due to the need for various safety permits. Using a gas water heater can address all these issues. First, regarding cost and environmental concerns, gas boilers use combustible gases with zero pollution emissions. They also feature intelligent pressure control, eliminating risks like explosions or carbon monoxide poisoning. Due to advanced technology, gas boilers occupy less space and are easy to operate without needing a specialist. Just press a button, and everything runs automatically. As they are not coal-fired boilers, no safety permits are required.
