Abstract
A wildfire defense spraying system installed on a property with combustible surfaces and adapted for spraying the property and combustible surfaces with an environmentally-clean water-based liquid fire inhibitor for defending against wildfire by inhibiting fire ignition and flame spread caused by hot flying wildfire embers created during a wildfire storm. The wildfire defense system includes: a storage tank containing an environmentally-clean liquid fire inhibitor comprising a majority amount of tripotassium citrate (TPC) and minor amount of triethyl citrate (TEC) dissolved in a major amount of water according to a prespecified formulation, wherein the environmentally-clean water-based liquid fire inhibitor remains stable without the formation of solids at expected operating temperatures, and ready for immediate spraying on combustible surfaces. A hydraulic pump system is connected to remote power control switch employed to supply electrical power to the hydraulic pump, and remotely activated. A plurality of spray heads is mounted about the property, in fluid communication with the storage tank, and supplied with environmentally-clean water-based liquid fire inhibitor by the hydraulic pump system. During operation, the spray heads spray liquid fire inhibitor from the storage tank forming a spray pattern that covers the property and combustible surfaces to be defended against wildfire embers. When the hydraulic pump system completes pumping and spraying the environmentally-clean water-based liquid fire inhibitor in the storage tank, the hydraulic pump system automatically shuts off, and as water molecules in the sprayed environmentally-clean water-based liquid fire inhibitor evaporate to the environment, thin potassium salt crystalline coatings form on the sprayed combustible property surfaces, inhibiting fire ignition and flame spread in the presence of wildfire.
