Sodium hydrogen carbonate (also known as sodium bicarbonate orbicarbonate of soda) has the chemical formula NaHCO3. When it is heatedabove about 80°C it begins to break down, forming sodium carbonate, water and carbon dioxide. This type of reaction is called a thermal decomposition.

It would gradually turn into a solution of sodium carbonate.
The hydrogencarbonates (bicarbonates) are not as stable as the carbonates. In aqueous solution of a bicarbonate the following equilibrium exists:
2HCO3(-) + H2O = CO3(2-) + CO2 + H2O
On prolonged boiling of the solution, the bicarbonate will almost entirely get converted to the more stable carbonate with the liberation of carbon dioxide, just like it happens when the pure or dry salt is heated.
So, the solution becomes that of sodium carbonate on continued heating
I'm guessing that you should get Na2CO3 as a white solid if you heat the solution at a high temperature (about 200°C)
Going by the chemical reaction :
2NaHCO3 → Na2CO3 + H2O + CO2
Usually, solid sodium bicarbonate decomposes in correspondence to the above equation. I do have sodium bicarbonate solution in the lab, will try heating it and let you know.
