Abstract
The article analyzes the efficiency of using oxygen-enriched air to control combustion in a steam boiler of a steam-blowing power plant of PJSC “Magnitogorsk Iron and Steel Works”. In the boilers of a steam-blowing power plant, a mixture of three gases is burned: natural, coke and blast furnace. In the case of a change in the ratio of gases, the combustion conditions and the geometric characteristics of the flame change. In some cases, this leads to an undesirable increase in the heat load in the boiler elements, especially in the superheater. Since the task of boilers of a steam blower power plant is to provide blast furnace production with air blast enriched with oxygen, the work of turbo expanders is directly related to the rhythm of the blast furnace. In the case of reducing the load of the blast furnace, there is an excess of air blast, which can be used to solve other problems, in particular, to control the combustion process in the boiler furnace. The article presents the results of numerical simulation of thermal fields in the furnace of an energy boiler of a steam-blowing power plant using oxygen enriched air.
