Abstract:
1. A method of deicing surfaces of highways using hot saturated salt brine comprising: (a) placing salt blocks and water into an emptied brine tank; (b) generating hot brine by: (c) supplying diesel fuel to a fuel tank located at the hot water generator and a fuel tank located at the 220 volts electrical generator; (d) regulating pressure of the circulating water with a bladder tank; (e) controlling the hot brine delivery rate to a spray boom with a plurality of half inch inside diameter low voltage solenoid valves (f) controlling hot brine delivery to the 220 volts circulation pump, brine tank and the spray boom with a plurality of half inch inside diameter stainless steel ball valves; (g) spraying hot brine to surfaces of highways with a plurality of half inch pipe thread stainless steel jet spray nozzles that are attached to the spray boom; (h) supplying hot brine to a hose reel system to spray hard to reach areas; (i) preventing spray drifting at the spray boom with a curtain surrounding the spray booms, wherein the curtain consisting of either burlap material or a used conveyor belt; (j) providing a circuit breaker panel for controlling of the 220 volts voltage to the circulating pumps, the hot water generator, and a float switch in the brine tank; (k) weatherproofing an electrical panel that contains electrical connections for the hot water generator and circulating pump; and (l) controlling pressure of the hot brine that is being delivered to the spray nozzles that are located at the spray boom with a pressure control switch.
