This post was last edited by Zaihui Kangqiao on 2016-8-26 at 08:38. 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! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What are the hazards of resin leaking into a thermal system? Answer: When resin leaks into the thermal system, it decomposes under high temperature and pressure, turning into acids, salts, and gaseous products. This reduces the pH value of the boiler water, and the steam carries low-molecular-weight acids, posing a risk of acidic corrosion to the boiler and the turbine.
When resin leaks into the thermal system, it decomposes under high temperature and pressure, turning into acids, salts, and gaseous products. This reduces the pH value of the boiler water, and the steam carries low-molecular-weight acids, posing a risk of acidic corrosion in the boiler as well as in the turbine.

First, it causes blockage of the inlet filters for the feed water pump and the pre-pump； The resin that escapes ends up in the thermal system and eventually reaches the boiler; when heated, it adheres to the tubes of the water wall and economizer surfaces, interfering with heat transfer and even causing overheating and tube failure.

Resin has high viscosity and tends to coking.
When resin leaks into the thermal system, it decomposes under high temperature and pressure, turning into acids, salts, and gaseous products, which lowers the pH value of the boiler water.
