System for unblocking or cleaning ducts by means of a controlled local reaction

A system for unblocking or cleaning ducts by means of a controlled local reaction, the system comprising:

• a tool capable of allowing a controlled reaction to take place near a blockage;
• a closed-loop control system;
• control valves configured to be controlled by the closed-loop control system, the control valves configured to clean or remove one or more obstructions from inside one or more lines by controlling injection of a flow of a first solution and a second solution into a reactor, the first solution and the second solution configured to react with one another within the reactor;
• a diffusor configured to discharge a mixture of the first solution and the second solution to the one or more lines;
• and
• a hall sensor operatively coupled to a spring, the hall sensor configured to identify movement of the spring, where such movement is indicative of physical contact of the diffusor with the one or more obstructions, the hall sensor being coupled to the diffusor.
