【Daily Question】Chemical Engineering Principles 271: Boiler Startup (December 22)
Thread Content
This post was last edited by “Back to Cambridge” on December 26, 2015, at 13:22. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their basic knowledge of chemical engineering. Subsequently, series such as “Fundamentals of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage continued participation from everyone this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What preparations should chemical personnel make before starting a boiler? Answer: 1) Before starting the boiler, it is necessary to test whether the feedwater and boiler water meet the required standards; only if both are satisfactory can the boiler be started. 2) The chemical dosing equipment and its related systems must be in good standby condition, and the chemical tanks should contain sufficient amounts of chemicals. 3) All sampling devices must be in standby mode, and all valves must operate smoothly. 4) The blowdown valves must function properly. 5) There should be enough testing chemicals available, and the instruments must be in good condition
What preparations should the chemical personnel make before starting the boiler? The following tasks should be completed before starting up: 1) Before igniting the boiler, it is necessary to test whether the feedwater and boiler water meet the required standards; only if both are satisfactory can the boiler be ignited ； 2) The chemical dosing equipment and its system should be in good standby condition, and the chemical tank should contain sufficient amount of chemicals ； 3) All samplers should be in standby mode, and all valves should operate smoothly ； 4) The sewage discharge valve should be flexible and functional ； 5) The laboratory reagents should be complete, and the instruments should be in good condition ；

Answer: 1) Before igniting the boiler, it is necessary to test whether the feedwater and boiler water meet the required standards; ignition can only be carried out once both are found to be satisfactory. 2) The chemical dosing equipment and its associated systems must be in good standby condition, with sufficient amount of chemicals available in the tanks. 3) All sampling devices should be in standby mode, and all valves must operate smoothly. 4) The blowdown valves must function properly. 5) There should be enough testing chemicals available, and the instruments must be in good condition

The boiler water should be tested before ignition, and it must be fully compliant. The chemical dosing equipment and its system are in good standby condition. All samplers are in standby mode, and all valves operate smoothly. The drain valve should be flexible and easy to use. The laboratory is equipped with a full range of reagents and complete instruments.
