Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for preventing closure of a plate type heat exchanger. SOLUTION: The method for preventing the closure of a plate type heat exchanger in an apparatus for treating a gas containing an easily closure-causing substance having the exchanger as a heater and/or a cooler comprises the step of (a) setting the width of a plate channel of the exchanger in the apparatus to 6 to 25 mm, and (b) setting of the mean flowing speed per unit sectional area of the plate channel of the gas passing the exchanger to 3 to 15 m/s. The closure of the exchanger can be significantly reduced in the heat exchanging of exhaust gas generated in the manufacturing step of a (meth)acrylic acid or its ester or in the step of discarding the gas.
