Matching method of fire coal for cement calcination

Abstract

The invention discloses a matching method of fire coal for cement calcination. The method comprises the following steps: S1, carrying out chemical component analysis on ingredients in each ingredientarea to obtain chemical components of limestone for the ingredients and auxiliary materials; S2, performing quality analysis on the to-be-matched coal types to obtain industrial analysis data, heat productivity and coal ash chemical analysis of each to-be-matched coal type; S3, determining coal types preliminarily matched with ingredients in each ingredient area; S4, firing the preliminarily matched coal types into coal ash, and doping the coal ash into ingredients of the corresponding ingredient areas to form a mixture; S5, performing a burnability test on the mixture, and screening out a coal type with a good burnability grade as coal for burdening in a corresponding burdening area; a production line is guided to select a proper coal type, indexes of the production line are optimized, selection and use of different fuels are guided, and theoretical and data support is provided; therefore, the purposes of saving energy and reducing consumption are achieved, and product quality is improved.

Description

technical field [0001] The invention belongs to the technical field of cement coal combustion, and more specifically, the invention relates to a matching method of coal combustion for cement calcination. Background technique [0002] The rational use of energy in the cement industry has always been the focus of researchers. The rapid development of the cement industry has brought about problems such as resources, energy, and the environment. These problems have seriously restricted the development of the cement industry. Therefore, how to use energy efficiently and rationally is particularly important to my country's cement enterprises. [0003] In my country's cement industry, especially in the production of new dry process cement, the main fuel used is coal, and the selection and utilization of fuel determine the economic benefits of the enterprise to a large extent; my country's coal resources are widely distributed, so the quality of coal It is very complicated; the inco...

Problems solved by technology

[0003] In my country's cement industry, especially in the production of new dry process cement, the main fuel used is coal, and the selection and utilization of fuel determine the economic benefits of the enterprise to a large extent; my country's coal resources are widely distributed, so the quality of coal It is very complicated; the incorporation of coal ash after combustion of different coal qualities will have an important impact on the composition of cement raw materials and the calcination of clinker. It is based on manual experience to determine the type of coal mixed in cement in each region, which has a great subjective influence. Cement kiln is one of the earliest industrial equipment to use pulverized coal as fuel, but the research on the combustion process of pulverized coal started relatively late
