The heat shield was designed for ensuring thermal protection of people, fire-extinguishing machinery and equipment during operations for eliminating emergencies involving an oil and gas gusher. Also, in case of an explosion, they provide mechanical protection of the personnel against possible injuries by fragments of processing equipment.
These shields are placed around a burning flowing, whereas the water, supplied via the nozzles, detaches the flame from the wellhead allowing the user to carryout emergency-eliminating operations without resort to echelon protection.
