ABSTRACT:
A system and process for improving the combustion of fuel oil in boilers employs: (1) dual homogenization of fuel oil and water; (2) recovery of heat from, and injection of, boiler waste water in the homogenization system; (3) mixing of urea and boiler waste water and injection into the boiler exhaust gases. The system of the invention includes:(a) a fuel service subsystem (11) with a boiler (36);(b) a dual subsystem (13) for homogeneously intermixing boiler waste water and fuel oil, the dual homogenization subsystem (13) including substantially similar primary and secondary homogenization subsystems, each of which includes at least one low pressure homogenization chamber (75, 18) preceding at least one high pressure homogenization subsystem (83, 27), with a compensating valve (74, 82, 17, 26) preceding each homogenization chamber for inducing cavitation;(c) a boiler blow down water and heat recovery subsystem (12); and(d) a urea and waste water mixing and injection subsystem (14);wherein the fuel service subsystem (11) leads to the dual homogenization subsystem (13), boiler blow down water from the boiler blow down water and heat recovery subsystem (12) empties into the dual homogenization subsystem (13), and urea and wastewater from the urea and waste water mixing and injection subsystem (14) flow into the boiler exhaust gas stream (66).
