1. An incinerator system comprising: an incinerator having a smoke path; a monitor unit for continuously monitoring exhaust gas components in said smoke path; a gas sampling unit for sampling the exhaust gas components from said smoke path and for carrying the exhaust gas components to said monitor unit with a constant flow rate by using a sampling nozzle disposed in said smoke path, a valve, a filter and a pump; and a combustion control unit to control combustion condition of said incinerator by the measurement results by said monitor unit; wherein said monitor unit includes: a gas inlet pipe for introducing the exhaust gas components; a corona discharge chamber having a needle electrode; a gas feed pump for introducing the exhaust gas components to said corona discharge chamber; a corona discharge power supply for supplying a negative voltage to said needle electrode; a surplus gas exhaust port for releasing surplus gases residing within said corona discharge chamber; a mass spectrometer for mass-analyzing ions created by corona discharge; and means for adjusting a pressure in said corona discharge chamber to a desired level. 2. The incinerator system according to claim 1, wherein said desired level of pressure in said corona discharge chamber is higher than atmospheric pressure. 3. The incinerator system according to claim 1, wherein said surplus gas exhaust port is in said corona discharge chamber. 4. The incinerator system according to claim 1, wherein external release of surplus gases residing within said corona discharge chamber is controlled with a gas release valve provided at said surplus gas exhaust port. 5. The incinerator system according to claim 1, wherein a temperature of said incinerator is regulated in accordance with the quantity of dioxin so as to reduce dioxin in the exhaust gas from said incinerator.
