Advantages&Features of the Cast Silicon Aluminum Heat Exchanger:
1) Space advantages: compact structure, small volume, light weight and small occupied space;
2) Material advantages: made of silicon aluminum alloy, high heat exchange efficiency and strong corrosion resistance;
3) Functional advantages: super acid corrosion resistance, super thermal conductivity; Reverse flow of flue gas and water to strengthen heat exchange.
4) Product features: the combustion chamber has a large furnace area, low temperature in the furnace and uniform distribution.
5) High efficiency and energy saving: efficiency up to 108% (water outlet temperature 30 ºC)
6) Safe and reliable: the rotary design is adopted for the water around the furnace, which avoids the dry burning phenomenon in the application process from the structure;
7) Service life: no weld, no stress, one-time molding by fine casting process, large heat exchange area and long service life;
The cutting-edge technology of our Cast Silicon Aluminum Heat Exchanger:
1)premixed combustion technology:
The pre-premixing technology means that the gas and air are premixed before the fan, and the premixed air enters the combustion chamber through the fan. The gas servo proportional valve and the automatic premixing control technology enable the gas to be fully mixed with the air in proportion before combustion. By adjusting the gas proportional valve, the gas can be burned with high efficiency and low emission. The metal fiber burner is used to make the premixed gas burn evenly on its surface. The existence of local high temperature is avoided, the emission of nitrogen oxides is reduced, and radiation heat exchange is realized.
2)Condensing heat transfer technology:
The core component of the fully premixed low nitrogen condensing gas boiler is the main heat exchanger made of silicon aluminum alloy, which integrates the combustion chamber, flue and water channel. The silicon-alumina heat exchanger has good corrosion resistance and high ribbing efficiency. In a limited volume, the columnar heat-absorbing column keeps a large heat exchange area. The combustion chamber and outlet are located above the dry silicon-alumina heat exchanger, the water inlet is located at the dry bottom, the temperature of the water flow increases gradually from bottom to top, the temperature of flue gas gradually decreases from top to bottom, and the reverse flow ensures that each Part of the heat exchange temperature difference is the largest, and it can conduct sufficient heat exchange. It can absorb the sensible heat in the flue gas and most of the latent heat of water vapor, effectively reduce the exhaust gas temperature, and make the water vapor in the flue gas saturated and precipitated, so as to achieve real high efficiency, energy saving, Environmental purpose.
