🔵 According to international standards, the most common approved design is used to produce boilers or hot oil heaters. It is a German design model that consists of two annular coils and The shell part is formed. 🔵 As you know, in the thermal system of boilers, the different stages of heat transfer are called a thermal pass, and in the following plan, the path of these passes has been tried to be clearly defined. The first thermal Pasali

Bile transfer between the big tunnel and The shell for increasing the absorption of thermal energy is one of the advantages of this plan, which is to increase the absorption of radiation waves and thermal energy from combustion materials inside the path of the furnace and ring coils. Proper turbulence due to the creation of turbulent circulation waves in the path of the resulting hot gases and other factors considered in the design of the boundary surfaces of the coils increases the turbulence and as a result the heat absorption factor increases. Excellent inside the coils, the combustion products are easily removed and prevents the accumulation of soot and adhesion on the internal surfaces. The shell and the body in this product are supposed to play the role of support and connection in the mechanical building in such a way that with detailed design and engineering, it is possible to insulate the interior with special fireproof concrete, it is possible to install tubular coils, and it is also possible to install doors and chimneys and connections. And finally, it provides the chassis and base for the device, and at the same time, the design and construction of this part plays a significant role in creating thermal passes, boiler efficiency and stable mechanical strength of the device.
The most important part in the boiler The heaters of these coils are oil, therefore, according to the latest approved and popular designs in the world and most importantly, excellent performance, these coils are produced in annular form and two layers of special alloy and fire retardant pipes. In terms of construction design, coils have technical complications, such as the appropriate diameter of the coils, the way they are rolled (longitudinal distance and the length of the pipes, welding to create proper penetration in the butt connection of the pipes). The necessary technical failure will cause burning of the pipes and finally fire in the boiler during the operation of the device.
