This proportional coil is applied to the "Full Premix Combustion Proportional Valve" series.

The fully premixed burner is made of fiber woven fabric of iron chromium aluminum and some rare metals to produce a combustion head. It has excellent breathability, uniform pore distribution, short flame on the surface of the burner, and a burning intensity of up to 2500kw/m.

According to the different output power, there are two basic modes of flame. When outputting at high power, it is a blue flame, and the combustion characteristics are: 1 Flame forms outside the fiber surface; 2. Most of the thermal energy exists in combustion products; 3. The surface temperature of the fiber is low.

Another flame mode is the infrared radiation mode at low power output, and the combustion characteristics are: 1 Burning occurs on the surface of fibers; 2. The radiation energy is mainly infrared; 3. The surface temperature of the fiber is high. When adjusting the power output, the flame changes between the two modes.

Due to the fact that the fully premixed burner basically eliminates the extreme high temperature in the combustion chamber, it reduces the generation of nitrogen oxides and is an energy-saving and environmentally friendly burner.

The fully premixed gas combustion technology is also applied to gas wall mounted boilers.

The characteristic of this type of wall mounted furnace is that as a mature heating terminal system, the water supply temperature of the water floor heating system is relatively low, usually around 40 ℃ to 50 ℃. The characteristic of the water supply temperature in the water floor heating system determines that when wall mounted boilers are combined with the water floor heating system, this temperature characteristic must be considered. Compared to ordinary wall mounted stoves, condensing wall mounted stoves can more conveniently and perfectly combine with water and floor heating.

When the outdoor temperature is below -3 ℃, the system demand temperature of the wall mounted furnace will be 57 ℃ lower than the dew point temperature of the flue gas. At this time, ordinary wall mounted furnaces must use a water mixing device to reduce the water supply temperature and increase the return water temperature, in order to avoid long-term lower dew point temperature inside ordinary wall mounted furnaces and meet the water supply temperature required by the water floor heating system. However, the condensing wall mounted furnace does not need to use a water mixing device and can directly provide hot water to the water floor heating system.

According to the energy efficiency standard of domestic wall mounted furnaces - GB20665-2006, the thermal efficiency of ordinary wall mounted furnaces under full load is about 90% when the supply and return water temperature is 80 ℃/60 ℃, and the thermal efficiency of condensing wall mounted furnaces under full load is about 99%. According to the relevant regulations of EN483, when the supply and return water temperature is 50 ℃/30 ℃, the thermal efficiency of the condensing wall mounted furnace under full load is about 105%, which can reach 109%. The supply and return water temperature of 50 ℃/30 ℃ just meets the water temperature requirements of the water floor heating system, and there is no need to operate the condensing wall mounted furnace in the low efficiency high temperature section, which can fully play the energy-saving role of the condensing wall mounted furnace.

The solenoid valve is the actuator, and the coil is the primary power. This coil is made of pure copper enameled wire, resistant to high temperature of 180 degrees, and sealed with plastic on the periphery. Explosion proof, aging resistant, anti impact. Ensure the stability of the proportional valve.
