Method of heating «with natural gas and
liierfor certain devices

The invention relates generally to the heating of. Industrial furnaces, stoves or other devices ait using natural gas, and particularly relates to the combustion of a high content of methane and other hydrocarbons having ¹¹¹ gas ·

The flame of a natural gas normally contains carbon dioxide and water vapor · The proportion of solid
Components in the exhaust gas per cubic meter are significantly larger with natural gas than with town gas. This results in considerable reductions in performance when switching from heating devices previously operated with town gas to operation with natural gas.

The invention sets itself the task of »a process
create that improves the combustion of natural gas in that the heat radiation of the flame increases and thereby a better heat transfer to the arrangement to be heated is achieved. The invention essentially strives for a method, the application of which results in an improvement in the overall energy efficiency of the
