You can disable the chapter, section etc. number with the "prefix=no" 
setting
but you should also add "way=bytext" because the prefix setting won't stop
context from resetting the counter with each new chapter, or section.

%% begin example
\setupformula[prefix=no]

\starttext

\chapter{Chapter}

\placeformula
\startformula
1 + 2 = 3
\stopformula

\stoptext
%% end example
