| Abstract: | The radiation transmissivity is an important factor to be considered in temperature calculations of boiler heat delivery surfaces,but not much concern is being paid to its influence on the accuracy of the calculated temperatures. Starting from the definition of radiation transmissivity,a formula suitable for engineering application is derived and has been successfully applied in some reconstruction projects.Requirements in precision and range of applicability,asked for by boiler design and check calculations,are satisfied. |
