Gas radiant tube is the development trend of radiant tube in the future

Radiant tubes are pipes that extend from the center to all directions. It refers to the non central pipeline (or main pipe), which transmits the action quality of the main pipe to the designated or non designated address. Radiant tube is widely used in heating furnace and is the main heating element of heating furnace. At present, the radiant tubes used are mainly divided into gas radiant tubes and electric heating radiant tubes. Among them, the thermal efficiency of gas radiant tube is about twice that of electric heating radiant tube. Therefore, gas radiant tube is the development trend of radiant tube in the future.

Under the condition of modern market economy, the competition of radiant tube enterprises is becoming more and more fierce. In order to increase market share, enterprises are constantly improving radiant tubes. However, technological innovation is very difficult. In order to reduce the R & D cost of radiant tubes, enterprise R & D personnel should accurately predict the development trend of products and adopt theoretical methods and tools to realize product innovation and rapid design. Under the guidance of innovation theory, innovation practice will get twice the result with half the effort. The development of products and their technology always follows certain objective laws. The same law is often repeatedly applied in different product technology fields, that is, there are laws to follow in the process of product improvement and technological transformation in any field, and the creation and upgrading of all technologies are development. TRIZ technology evolution theory is specialized in the evolution of technology system. It has experienced three stages: the traditional TRIZ evolution theory, the development of TRIZ evolution theory and direct evolution theory, including technology evolution theory (ET), technology evolution guidance theory (GTE) and direct evolution theory (DE). TRIZ technology evolution theory is specialized in the evolution of technology system. The theory of technological evolution reflects the importance, stability and repeatability of technological systems, components, systems and environments in the process of evolution. Each evolutionary rule contains a different number of specific evolutionary routes and patterns. Using TRIZ technology evolution theory, this paper analyzes the evolution process of each main performance of radiant tube, summarizes its evolution route, predicts its future development direction, and provides reference for the innovation and development of relevant products of enterprises.
