Incineration furnace combustion control method based on temperature field measurement technology

Abstract

The invention relates to the field of design of incineration furnaces, in particular to an incineration furnace combustion control method. The incineration furnace combustion control method comprises the following steps: incineration furnace outlet temperature distribution conditions are provided; an incineration furnace outlet temperature two-dimensional plane distribution diagram is built according to the incineration furnace outlet temperature distribution conditions; an outlet temperature and the position of a high-temperature area of an incineration furnace are judged according to the incineration furnace outlet temperature two-dimensional plane distribution diagram; combustion working conditions are controlled according to the outlet temperature and the position of the high-temperature area; the outlet temperature of the incineration furnace is adjusted; a flame center in the furnace is positioned in a center area of the incineration furnace; an incineration furnace outlet temperature field is divided into multiple areas according to the incineration furnace outlet temperature two-dimensional plane distribution diagram; and the uniform distribution of the temperature field is controlled through the area division. The control method can guarantee the outlet smoke temperature uniformity of the incineration furnace to reduce original smoke pollutant concentration and to increase the boiler steam quantity, and can be applied to various household garbage incineration furnaces.

Description

technical field [0001] The invention relates to the field of incinerator design, in particular to an incinerator combustion control method based on temperature field measurement technology. The method can ensure the uniformity of flue gas temperature at the outlet of the incinerator, thereby reducing the concentration of pollutants in the original flue gas and improving the efficiency of the boiler. The amount of steam can be applied to various domestic waste incinerators. Background technique [0002] With the increase of domestic waste production year by year and the increasing pressure on waste disposal, the state has attached great importance to the improvement of waste harmless treatment capacity in recent years. Among them, waste incineration, as an energy utilization technology, has high processing efficiency, fast capacity reduction and mature technology. , has developed rapidly. In 2006, the national garbage harmless treatment volume was 74 million tons, of which o...
