Show I Page 121 The first of four joint meetings established the mission and rules and divided the task into five parts: Part I Define the optimum windbox/burner system. The optimum system define the number, type, size of the burners required, and all the design parameters which describe the burners and wind box system with assurance all of the requirements and guarantees can be achieved with sufficient margin in accordance with good engineering practice. The boundaries of the boiler's pressure parts (waterwalls) are defined and are to be considered fixed. Part II Comparing the solution of Part I to the "as built" system currently installed and operating, evaluate the components of the installed system composed of the common windbox and four burners and determine what, if any, parts thereof can be either modified or replaced to yield the same level of confidence in the performance and margins as the optimum solution determined from Part I would yield. A. Rules 1 . Downtime of each boiler is to be kept to an absolute minimum to eliminate the high risk of loss of refinery capacity due to loss of steam. The normal steam load per boiler is between 150,000 Ibs/hr and 200,000 Ibs/hr with all three boilers on line. 2. Any part to be replaced shall be shop modularized to enhance installation of that part. |
