This post was last edited by Zaihui Kangqiao on 2016-8-30 at 09:38. The Chemical Engineering Theory section is launching a \"One Question per Day\" activity starting today, aimed at helping everyone reinforce their basic knowledge in chemical engineering. Subsequent series will include those on \"Principles of Chemical Engineering\", \"Mass Transfer and Separation\", \"Thermodynamics in Chemical Engineering\", and \"Chemical Process Engineering\". We hope you will give it your active support! Wishing everyone a happy Christmas! Answers to the questions in the \"One Question per Day\" activity can be viewed directly; the thread will be closed after 1 day ! To encourage everyone’s continued participation this year! You get 3 wealth rewards just for participating, and an additional 4 wealth points for correct answers~~~ Short answer question: What are the basic principles of the protection system for shutting down boilers when they are not in use? Answer: 1. Prevent air from entering the vapor system of the unused equipment; 2. Keep the metal surfaces on the vapor side of the equipment dry, and strictly control the temperature to prevent dew formation. 3. If the interior of the boiler is filled with water or there is a water film on the metal surface, a corrosion inhibitor can be used to put the metal surface into a passivated state or to form a water-impermeable adsorption film.
What are the basic principles of the protection system for shutting down a boiler and putting it into standby mode? Answer: 1. Prevent air from entering the vapor system of the equipment that is not in use; 2. Keep the metal surfaces on the vapor side of the equipment dry, and strictly control the temperature to prevent dew formation. 3. If the interior of the boiler is filled with water or there is a water film on the metal surface, a corrosion inhibitor can be used to put the metal surface into a passivated state or to form a water-impermeable adsorption film.
To prevent air from entering the moisture system of equipment that is not in use, corrosion inhibitors can be used; this is applicable when the interior of the boiler is filled with water or there is a water film on the metal surfaces. Strictly control the temperature to prevent dew formation

(1) Prevent air from entering the steam system of the boiler that is not in use. (2) Ensure that the metal inner surfaces of the boiler steam system are dry when it is not in use. (3) Create a film with anti-corrosion properties on the metal surface. (4) Immerse the metal surface in an aqueous solution containing a deoxidizer or other protective agent.
