How do you calculate the radiation heat of a emmision gas mixture as a function of distance?In other words is there a way to determine what the temperature will be at a distance?

A) Use e.g. API 521 to calculate the radiation at you required distance.
B)
If you know the heat radiation on a body then you _can_ use Planck to calculate the surface temperature corresponding to this heat flux 8assuming that the body reaches a equlibrium temperature where the heat radiated is equal to the the heat received.
This will however give a very high temperature.
Instead you should find an equation for energy loss from free conductivity for this specific body (e.g. horz. pipe, flat plat or whatever). Perry (sec 10= can help you here and so will many other textbooks. If you want to go the extra mile you can also set up a spreadshhet where you do the same for forced convection (wind) and assume different wind spped. free convection (no wind) is however conservative.
Again assume heat in=heat out(equlibrium is max temp).
