Title:
FIREBREAK-FORMING EQUIPMENT
Document Type and Number:
WIPO Patent Application WO2001007115
Kind Code:
A3
Abstract:
Land surface treating equipment in the form of firebreak-forming equipment (10) comprises a linearly extending combustion chamber defining shell (12) formed to define a burning chamber (14) in conjunction with land along which it is intended to be used once operatively positioned, fitted with a burner providing arrangement (16) used for creating a combustion reaction within the chamber (14). The equipment (10) further includes a fire extinguishing layout in the form of tubes (18) extending along the sides of the shell (12), that are fitted with spaced nozzles (20) aimed to discharge fire extinguishing agent alongside the shell (12) during operative use. The equipment (10) is towable along land via ski formations (22). The dispensing of combusted gases and other products take place via chimneys (26). The burner providing arrangement (16) is fitted to the upstream side of the shell (12) resulting in the ignition of growth on entering the chamber (14) during progress of the equipment (10) along land. The length of the shell (12) extending rearward from the location of growth ignition promotes the burning to extinction of ignited growth within the burning zone (14). This effect is enhanced by the smothering effect within the chamber (14) caused by the overwhelming presence of carbon monoxide and carbon dioxide during operative use of the equipment (10).
