Description

Brief Introduction of the Cast Silicon Aluminum Heat Exchanger:

The special cast silicon aluminum heat Exchanger for commercial condensing low nitrogen gas boiler is cast from silicon aluminum alloy, with high heat exchange efficiency, corrosion resistance, durability and high hardness. It is applicable to the main heat exchanger of commercial condensing gas boiler with rated heat load below 2100 kW.
The product adopts low-pressure casting process, and the molding rate of the product is higher than that of similar products at home and abroad. A removable cleaning opening is set on the side. In addition, the flue gas condensation heat exchange area adopts the company's patented coating material, which can effectively prevent ash and carbon deposition.
Technical principle:
The condensing cast silicon aluminum main heat exchanger is of cast silicon aluminum structure, integrating combustion chamber, flue and water channel. Cast aluminum heat exchanger has good corrosion resistance. In a limited volume, rib columns are used to increase the heat exchange area. The combustion chamber and water outlet are located above the main heat exchanger, and the water inlet is located at the bottom. The temperature of the water flow gradually increases from bottom to top, and the temperature of the flue gas gradually decreases from top to bottom. The reverse flow ensures that all points in the heat exchanger can carry out sufficient heat exchange, absorb the sensible heat and most of the latent heat of water vapor in the flue gas, effectively reduce the flue gas temperature, and saturate and precipitate the water vapor in the flue gas, so as to achieve the purpose of high efficiency, energy conservation and environmental protection.

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.
