Fire water plant i
Hydrogen boilers with no measurable NOx emissions. In some versions the fuel is a ratio of already mixed hydrogen and oxygen, ratio of pre-mixed hydrogen and oxygen, or the fuel comprises hydrogen and the burner also contains a separate nozzle for introducing a ratio of oxygen. In some versions, these ratios are stoichiometric between hydrogen oxygen. Some versions show burner systems that monitor the combustion process, which is a condensing process, and have hydrogen oxygen pilots and ultraviolet flame detectors. These hydrogen boilers can supply all the process steam needed by a system or can supply part of the process steam needed by a system.
1 . A device comprising:
a combustion chamber having a fire tube;
a pressure vessel containing;
condensing coils;
a firewater outlet associated with the condensing coils;
water surrounding the condensing coils;
