Classification:
safety]For non-explosive boilers, the material selection determines that the cast iron boiler will not explode. The water-packed fire is designed to prevent dry burning and has high thermal efficiency.
environmental protection]Through the design of efficient heat exchange surface and reducing flame temperature, the emission of nitrogen oxides is greatly reduced.
high efficiency and energy saving]Full water-cooled wall structure, high-efficiency convective heat transfer surface of heat collection cone, thermal efficiency up to 94%, if the use of multiple joint control of cast iron boilers can further improve the efficiency of use.
long life]The unique intergranular structure of the cast iron boiler has strong corrosion resistance and oxidation resistance, and its life is greatly extended to 3-4 times that of ordinary steel boilers.
easy to install]The unique modular structure adopts a plurality of independent pot pieces installation methods. Only the front, middle and rear pot pieces need to be assembled together through connecting sleeves and bolts. Welding is not required, capacity can be increased, and single pieces can be transported to the site for assembly to meet the needs of different working conditions such as basements, garages, roofs or narrow boiler rooms.
small volume]The boiler has a compact structure. Due to the particularity of cast iron, a large number of heating surfaces are arranged on a very small volume, and the volume is only 1/3 of the same tonnage steel boiler, which reduces the floor space and infrastructure costs to a considerable extent.
large furnace radiant heating surface]The radiant heating surface of the large furnace increases the heating area, and the efficient heat radiation heat transfer method is used to strengthen the heat transfer effect.
Unique side double water column design]The side double water column design not only increases the heat exchange area, but also forms a special structure that the inner column water cavity is hot and the outer column water cavity is cold, which enhances the water convection heat exchange effect and reduces the boiler outer surface temperature.
metal mechanical seal connection sleeve]The design of the metal mechanical seal connection sleeve with world cash ensures the high precision of boiler assembly, eliminates the leakage of boiler connection, and prolongs the service life of the boiler.
smoke water countercurrent system]Flue gas, water counterflow design, strengthen the heat exchange effect.
Unique heat collecting cone heating surface design]The heating surface of cone, staggered row and opposite top heat collecting cone is adopted. Regardless of the horizontal and vertical scouring of flue gas, all heat collecting cones are scoured by the turbulent flow of flue gas, and symmetrical steady vortex and reflux zone are formed on the back of the cone. The thermal boundary layer is continuously destroyed and re-formed, which makes the whole thermal boundary layer thinner, which is 3-4 times of the heat transfer coefficient of traditional heat transfer mode, and maximally increases the heat transfer area, the heat exchange efficiency is enhanced.
High quality low phosphorus pearlite cast iron material]Low-sulfur and low-phosphorus high-quality pearlitic cast iron has strong thermal shock resistance and thermal fatigue strength, resulting in a much better ability than steel boilers, with strong corrosion resistance and oxidation resistance; low-sulfur, low-phosphorus raw materials, It has good comprehensive mechanical properties, large elastic modulus, strong toughness.
full wet back design]Full water wall design, to prevent local overheating phenomenon, put an end to dry burning, reduce security risks.
