1. Conductive heating: for example, a metal rod, from end A to end B. This heating method is used to heat gas in our lives, but the heat loss of this heating method is relatively large, so we usually use this heating method to obtain a better heating effect. 2. Convection heating of stainless steel fan. This heating method is convection heating of a mixture of air and gas. This heating method also brings chemical heat loss and thermophysical loss, and ordinary atmospheric furnace is also this convection heating method. 3. Light wave radiation heating: This kind of radiation heating, the "direction" of the stainless steel fan is very strong, just like the principle that we wear a black suit to absorb heat in the sun, we all know that the sun is light wave radiation, so this kind of radiation heating The thermal efficiency is very high.
Structural features of stainless steel fan:
1. The stainless steel fan is mainly composed of impeller, shell, air inlet, motor, connector, cooling fan, etc. 2. The impeller adopts multi-wing single-inlet fan impeller, and adopts high-quality 304 stainless steel plate or 316 stainless steel plate. The blades are designed according to aerodynamic principles. The impeller consists of 10 vanes, a curved front disc and a flat back plate. The material is made of high-quality steel plate, high strength, good durability, and strict calibration of dynamic and static balance. Good gas performance, high efficiency and stable operation. 3. The air inlet adopts the convergence streamline vortex shrinkage mode, the air volume loss is small, and the stainless steel fan has strong working ability. 4. Cast steel connection between fan and housing. The cooling fan blades are mounted on the motor shaft head. The surface of the metal casting is provided with an inlet and outlet pipe interface to cool the metal casting and the shaft head to ensure the normal operation of the motor at high temperature. 5. The motor adopts a special motor, the liquid part of the fan adopts temperature-resistant materials, and the cooling structure is reliable. Compared with other boiler induced draft fans, it has the advantages of compact structure, convenient maintenance and high cost performance.
