Radiant tube heating device, has a variety of forms, such as ZhiGuanXing, casing, U, W, P, O, etc., of which with waste heat recovery device of u-shaped radiant tube heating device is applied more widely.Because the shape of the w-type tube has the characteristics of the double U, appropriate extension length can form between the double U tube.So this article with w-shaped radiant tube heating device, for example, USES the HTAC technology, the technical reform.Regenerative transformation mainly from high temperature flue gas efficient recycling as well as the high temperature low oxygen combustion two aspects, regenerative high temperature air combustion technology is applied in gas-fired radiant tube heating device, can make the radiant tube surface temperature distribution more uniform, heating power and heating quality, thermal efficiency is greatly improved, the radiant tube service life extension, significantly reduce the pollutant emissions.
