A system and method enable an incineration facility to be controlled and diagnosed, and the life cycle thereof managed, using a heat exchange and design program and operation mode analysis of an operator of the facility. Operation efficiency is improved by comparing and analyzing (a) initial design values of the incineration facility, (b) measured actual valued obtained by measuring waste composition and heating values changed after construction of the facility and (c) operation values indicating actual operation adjustment values and operating result values operated by the operator and by analyzing the operator. The design values, measured actual values and operation values are compared and provided as data in graphs and tables.
