Coke making method by adding biomass energy to mixed coal

Abstract

The invention relates to a coke making method by adding biomass energy to mixed coal, which is a technical proposal by mixing biomass fuel and mixed coal for making coke in a certain proportion. The method aims to replace coal for making coke with renewable energy sources, expand the resources of coal for making coke, reduce the independence on high-quality coal in the coke-making process and realize the optimal coke-making coal blending technology by using renewable energy sources instead of fossil energy sources. Compared with the prior traditional coal blending technique, the method has the advantages of simple technique and low equipment cost, and does not require repetitive constructions and remodifications on technical equipment; therefore, the method can greatly reduce the coke-making cost, save large quantities of high-quality coal resources, propel the utilization of renewable energy sources to realize energy saving and emission reduction, and reduce the secondary pollution of the biomass energy sources to the environment. The realization of the project has obvious economic and social benefits.

Description

1. Technical field [0001] The invention relates to a method for coking by adding biomass energy to blended coal, in particular to a method for producing coke by mixing biomass energy with blended coal, and belongs to the technical fields of coking chemistry and new energy. 2. Background technology [0002] In the process of coke production and preparation, different types of coking coal are used. After blending according to different proportions, the blended coal is added to the carbonization chamber of the coke oven, and the product coke and coke obtained by high-temperature dry distillation at 1200°C under air-isolated conditions are obtained. Coking products. The existing method is a traditional and relatively mature production process. Its shortcoming and deficiency is that it needs to consume a large amount of high-quality coal.

The existing method is a traditional and relatively mature production process. Its shortcoming and deficiency is that it needs to consume a large amount of high-quality coal. Although my country's coal resources are very rich, the resources of coking coal are limited but very limited. In recent years, with the The completion of some large coke ovens will consume a large amount of coking coal resources every year. Although the coal reserves are large, the resources of coking coal and fat coal are indeed becoming less and less, and their effective mining life is less than 20 years. In order to make better use of and protect limited high-quality coal resources. After a few years, iron and steel and metallurgical enterprises must seek an alternative fuel to reduce the use and dependence of coking coal to ensure the supply of coke fuel. Now some factories are expanding the use of coking coal in order to make rational use of coal resources. Scope, study the coal blending coking experiment using low-quality coal, in order to reduce the ble
