A method of burning waste liquid uses industrial burning equipment using liquid fuels and comprises, when burning the liquid in a mixed and dispersed state, pre-investigating the types and properties of each component and the mixed property, selecting suitable equipment using suitable method, setting suitable pre-conditions in terms of ideal burning range based on the state of burning of the equipment and the composition of exhaust gas, investigating suitable adjustment whether to combine pre-treatment methods, liquid injection methods, liquid mixing methods, ratio of air and fuels, most suitable equipment , low NOx means, additives, aqueous emulsion usage, controlling the adjustment of the ratio of waste liquid and additives injection and injection ratio, preventing the deviation of proper oxygen concentration range, maintaining ideal burning state, preventing damage to burning means, preventing damage of residues to equipments after burning, controlling the change of concentration of smoke accompanying the liquid composition, carrying out implementation of adjustment after deviation from normal circumstances, and confirming the implementation the controlling of dioxine concentration in the exhaust gas after or before after treatment and the management of allowable generation of NOx, smoke, halogen and heavy metal. Independent claims are also included for (1) a similar method wherein before the investigation of all conditions, the equipment was sprayed with water to reduce the content of NOx, and (2) a mixed liquid containing the treated waste liquid, poisonous gas or radiation lower than limit, Cl at less than 85000 ppm when the total burning of heavy oil is 2000 kg/h or less, 17000 ppm or less at 2000-4000kg/h and less than 1700 at 4000 kg/h or higher, N component such that the amount of NOx is less than limit, S component as such that the mount of SOx is less than limit, less than the limit amount of heavy metal, the amount of water of 0-60% or less, and the spaying means contains 100% or less eater. |
