This invention relates to heat engineering.

According to the main author. St. No. 996798 discloses a method for thermally deactivating waste gases by burning in a boiler furnace, includes a preliminary separation of waste gases containing a co-adensed phase into liquid and gaseous phases and supplying the gas liquid phases separately to the air and liquid paths of a combined burner II.

The liquid condensed phase is a hot mixture that contains organic components: phenols, fatty acids, organic bases, carbonyl compounds, resinous substances, among which resinous substances predominate. The liquid phase of the resin has a high viscosity, which at a temperature reaches a value of 35 ° WU. In order to achieve permissible viscosity (for example, for gear pumps 10 ° WU, for mechanical nozzles, the resin must be heated to temperatures above 160 ° C, which leads to high energy consumption. To reduce the viscosity, the resin must be heated in a special container.

The aim of the invention is to reduce the viscosity of the condensed liquid phase of waste gases and improve disposal by improving the transport and spraying of the liquid phase and reducing energy consumption for heating j The goal is achieved by ITSM, which, according to the method of thermal disposal of waste gases

Before condensation of the liquid phase before it is fed into the liquid path of the burner, water is added in an amount of 15-17% by volume and a resin-water emulsion is prepared.

The implementation of the method carried out in laboratory conditions. Waste liquid phase from fish smoking process was tested as a sample. Smolovod on the emulsion was prepared by known methods: pump-emulsifier, sparging and other sparging. The research results are summarized in the table. Research has established / that the emulsion emulator has the lowest viscosity at an emulsion when the water content in it is% by volume .. The optimum water content in the water emulsion is 16% by volume. A decrease or increase in the water content not only leads to an increase in the viscosity of the emulsion, but also degrades the quality of the burnout of carbon-containing components, chemical burns appear, and the content of carbon monoxide in the combustion products increases. Oxides of nitrogen and sulfur in the combustion products are absent, because the emulsion guide on the emulsion does not contain nitrogen and sulfur-containing components, which is its advantage as a fuel compared to fuel oil.

In comparison with the known method, in the proposed method, a reduction in viscosity, reduction of energy consumption for heating the liquid phase, and improvement in the quality of burnout of harmful components contained in waste gases is achieved.
