摘要： PROBLEM TO BE SOLVED: To provide a chemical cleaning method of a main steam pipe, an superheater and the like capable of inexpensively and efficiently cleaning a saturated steam pipe, the superheater and the main steam pipe without cutting.
SOLUTION: A pipe 11 for cleaning is pulled in a steam drum 1 through a manhole 1a of a steam drum 1. A joint pipe 10 is mounted on a tip of the pipe 11, and the joint pipe 10 is inserted into the saturated steam pipe 3. Valves 16a, 24a are closed, a valve 26a is opened, further a valve 18a is opened, and a chemical feeding pipe 19 is operated. Whereby the water is circulated in a circulation pump 13, the pipes 12, 11, the saturated steam pipe 3, the superheater 4, the main steam pipe 5, the pipes 23, 25, 26, 16, a heater 15 and a pipe 14, and the cleaning chemicals are added to the water. By continuing the circulation, the scale attached to inner faces of the saturated steam pipe 3, the superheater 4 and the main steam pipe 5 are eliminated.

摘要： PROBLEM TO BE SOLVED: To provide a treating method for remaining gas in an ammonia tank capable of safely treating ammonia gas remaining in the liquid ammonia storage tank by a convenient operation using simple equipment. SOLUTION: In the treating method, the ammonia gas remaining in the liquid ammonia storage tank is pulled outside the tank and is decomposed, that is, the ammonia gas pulled out by utilizing a pressure in the tank is guided to the ammonia treating equipment and is treated, thereafter, an inert gas is forcibly fed into the tank, the remaining ammonia gas is diluted, is allowed to flow out and the outflow mixed gas is guided to the ammonia treating equipment and is treated.
