Introduction to the thermal efficiency of U-shaped radiation tubes

A U-shaped radiation tube is a straight line that extends from the center in all directions. Refers to a non central pipeline (or trunk pipeline) that transports the substance of the trunk pipeline to a designated or non designated address. Radiation tubes are widely used in heating furnaces and are the main heating elements of the furnace. At present, radiation tubes are mainly divided into two types: gas radiation tubes and electric heating radiation tubes. The thermal efficiency of gas radiation tubes is about twice that of electric heating radiation tubes. Therefore, gas radiation tubes are the development trend of future radiation tubes.

At present, radiation tubes are mainly divided into two types: gas radiation tubes and electric heating radiation tubes. The thermal efficiency of gas radiation tubes is about twice that of electric heating radiation tubes. Therefore, gas radiation tubes are the development direction of future radiation tubes. Under the conditions of modern market economy, the competition among radiation tube enterprises is becoming increasingly fierce. In order to increase market share, radiation tube enterprises are continuously increasing. But technological innovation is very difficult. In order to reduce the R&D cost of radiation tubes, enterprise R&D personnel should accurately predict the development trend of products, adopt theoretical methods and tools, and achieve product innovation and rapid design. Under the guidance of innovation theory, innovation practice achieves twice the result with half the effort.

In order to improve the thermal efficiency of U-shaped radiation tubes, the most direct method is to increase the length of the radiation tube, increase the flow time of smoke inside the radiation tube, and fully exchange heat between the smoke and the radiation tube. However, if the length of the radiation tube is too long, it will bring problems in terms of strength, stiffness, manufacturing, and installation, which will affect the service life of the radiation tube. Subsequently, the structure of the burner was continuously improved to fully mix and burn the gas and combustion air, thereby improving the thermal efficiency of the radiation tube. The development of products and their technologies always follows certain objective laws, and the same law is often repeatedly applied in different fields of product technology. That is, the process of product improvement and technological transformation in any field is regular and can be followed, and all technological creations and upgrades can be achieved. Developing towards the most powerful functions. The TRIZ theory of technological evolution is a specialized study of the evolution of technological systems. It has gone through three stages: traditional triz evolution theory, triz evolution theory, and direct evolution theory. It has various forms such as Technology Evolution Theory (ET), Introduction to Technology Evolution System (GTE), and Direct Evolution Theory (DE). The theory of technological evolution is a specialized study of the evolution of technological systems. The theory of technological evolution reflects the important, stable, and repetitive interactions among technological systems, components, systems, and environments during the evolutionary process. Each evolutionary law contains a different number of specific evolutionary paths and patterns.
