Gas boilers include gas water boilers, gas hot water boilers, gas steam boilers, etc. Among them, gas hot water boilers are also known as gas heating and gas bathing boilers. Gas boilers, as the name implies, refer to boilers fueled by gas. Compared to oil-fired boilers and electric boilers, gas boilers are more economical, so most people choose gas boilers as steam, heating, and bathing equipment.

Condensing Boiler Structural Features
Boiler body structural features
1、WNSLThe condensing series boilers are designed with a horizontal wet-back structure, featuring a centrally low-lying combustion chamber and a symmetrically distributed heat exchange flue pipe design on both sides. This ensures uniform and stable heat exchange load, which is beneficial for the vapor-water circulation on the working fluid side, significantly reducing the occurrence of water shortage accidents and enhancing the safety of the boiler.
2The rational application of bell-shaped furnace liners and threaded smoke tubes with reinforced heat transfer elements not only enhances turbulent heat transfer of high-temperature flue gas but also effectively absorbs the thermal expansion and contraction of the furnace body.
3The boiler incorporates a design philosophy of large furnace tube, large drum, and large heating surface, ensuring complete combustion, reduced carbon buildup, fuel savings, and boasts significant features such as high efficiency, sufficient power, and strong overload capacity.
Condenser
1Installed on the boiler top, compact structure, with no floor space required.
2Reverse flow arrangement, large heat exchange temperature difference, excellent heat transfer performance.
3Utilizing specialNDSteel material with excellent resistance to condensation corrosion, significantly enhancing service life.
4Utilize a reasonable flue structure for easy condensate discharge, collection, and processing.
Self-contained system
1Utilizing a burnerPIDAdjustable technology, equipped with an Italian imported burner (Italkraft), to achieve air-fuel ratio configuration, ensuring complete combustion of the fuel.
2Boiler electric control fully automatic intelligent toggle operation interface, fully automatic control, automatic water level replenishment, automatic pressure control, automatic ignition and shutdown operations, with the advanced intelligent operating system.
3The control box occupies minimal space, making it convenient for future maintenance and upkeep.
(Burner)
1Imported from Italy, Original.ECOFLAM(Trade Name: YiKe Flange or YiGao), domestically assembled model.
2Installed with a proportional control instrument, it ensures accurate air pressure and adjustment, optimizing natural gas combustion efficiency and eliminating the rough tuning work of mechanical regulation.
3Our company, in coordination with the safety and economic aspects of natural gas combustion technology, has purchased multiple flue gas analyzers manufactured by the German company FISCHER. During boiler commissioning and operation, these analyzers provide the combustion unit with reliable digital data on its actual operating performance. Adjustments to the combustion unit's air pressure and gas pressure are made based on the data provided by the flue gas analyzers to ensureCOAndO2Emissions are below standard levels, further ensuring high combustion efficiency and eliminating waste.
