The i7 series boiler adopts FIR flue gas internal circulation combustion technology, which has the characteristics of low air excess coefficient, large regulation ratio, small exhaust heat loss, and low unit gas consumption. The flame has low requirements on the furnace volume, and the air and gas mixing area is separated from the combustion area (patented technology) to avoid the generation of transient nitrogen oxides and achieve ultra-low nitrogen without external installation.
It has the characteristics of low air excess coefficient, large adjustment ratio, small exhaust heat loss, and low unit air consumption. The flame has low requirements on the furnace volume, and the air and gas mixing zone is separated from the combustion zone (patented technology) to avoid the generation of transient nitrogen oxides and achieve ultra-low nitrogen without external installation.
The boiler is equipped with over-temperature alarm and interlock protection, over-pressure alarm and interlock protection devices; Digital fully automatic work, humanized interactive interface, boiler operation is simple and clear; Overpressure protection: If the pressure in the boiler exceeds the set value, protection measures will be triggered;
Adopting premixed plane combustion technology, NOx≤30mg/Nm3; The flue gas emission concentration is low, and the Ringelmann blackness is level i; The temperature gradient in the furnace is uniform, and the heat transfer effect is superior and efficient; The furnace body adopts wing tubes, which has sufficient heat exchange area to meet the heat exchange efficiency;
Far-infrared combustion requires a shorter furnace, which can significantly reduce the size of the boiler; The wing tube has a large heat exchange surface, which can effectively reduce the boiler volume with the same effect; The condenser and rear smoke box are integrated to further reduce the total volume of the boiler; i7 Compared with the same period last year, the size of ordinary boilers has decreased, and the larger the tonnage, the more obvious the advantages;

Valve instruments, controllers, sensors and other important accessories are all from well-known domestic and foreign brands, providing more guarantee for the long-term operation of the boiler.
The boiler is equipped with modules such as high-color touch screen, dynamic graphic display, multi-level menus and permissions, and automatic fault saving records, which is very user-friendly.
The boiler is designed as a whole and debugged in the factory. The user only needs to install water and electricity on site and it can be used normally.
The boiler is diffusion combustion, which can adapt to the technical needs of large tonnage. The nitrogen oxide emission is less than 30mg, which meets the atmospheric emission standards.
The boiler is highly adjustable, and the water temperature can be set arbitrarily between 30-90°C to provide heat for the heating system or provide hot water to users.
The boiler adopts a fully automatic control mode, which can automatically adjust operation, water level, and water temperature to achieve all-round automatic protection.
The main body is made of high-temperature resistant insulation materials, which can save more heat energy and higher water temperatures. The thermal efficiency of the whole machine is much higher than the standard requirements.
The wing tube is made of silicon aluminum alloy, which is corrosion-resistant and greatly extends the service life.
