Cast Si-Al Heat Exchanger for Modular Boiler
Product Description
Integrated cast silicon aluminum alloy heat exchanger, for generating hot water
Technical Principle of the Cast Silicon Aluminum Heat Exchanger:
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.
Unique Advantages Over Other Similar Products
1) The furnace volume of the combustion chamber is 50% larger than that of other similar products. The inner surface temperature of the furnace is lower and the distribution is more uniform, which greatly prolongs the service life of the burner
2) The water channel around the furnace adopts rotary design, so that the highest outlet water temperature is at the lower right of the furnace, which structurally avoids the dry burning phenomenon in the application of similar products
3) The water volume of the heat exchanger body is 22% larger than that of other similar products, and the cross-sectional area of the water channel is significantly increased. The chamfer of the water channel is simulated and optimized to reduce the water resistance and reduce the possibility of scaling
4)The unique design of diversion channel inside the water channel increases the heat exchange area, enhances the turbulence effect, strengthens the internal heat transfer, and makes the weight of the heat exchanger lighter
Product Superiority:
Aluminum alloy has good thermal conductivity, thermal conductivity is 8-10 times that of stainless steel, high heat transfer coefficient, compact; Low density and light weight.
Different materials to help the design of the high are limited, silicon aluminium casting is the high thermal conductivity material, its help height can be designed more, to get more than, reinforce the heat exchange area and help make the structure more compact.
Efficiency of different material to achieve the same help, help the area is different, the smaller the coefficient of thermal conductivity, the lower the fin height. At this point, high silicon cast aluminum qualitative coefficient of thermal conductivity of strengthening effect is very obvious.
