Abstract


The internal heating low-temperature carbonization craft has the characteristics of simple equipment,low investment,higher productivity and so forth in North Shanxi area. It increased the nitrogen content in the coal gas due to using the air combustion in the production process, which causes the coal gas calorific value to reduce. In addition,the scale of local semi-coke production enterprises is small, the semi-coke quality is bad, the energy consumption is high, and the environmental pollution is serious. Therefore, to optimize craft or develop the new craft to enhance the comprehensive utilization level of the coal has the important theory and the use value for local economic development.In view of that the gas calorific value is low, the experimental program of the oxygen enriched carbonization is proposed based on on-the-spot investigation of coal low-temperature carbonization application present situation in Northern Shanxi. According to the experiment data,the paper carried on material balance and thermal balance calculation,and proposed further search direction and industrialization scheme by the analysis and discussion of the oxygen enriched carbonization.The analysis of the experimental data proved that the oxygen enriched carbonization is feasible. The oxygen enriched carbonization can decrease the nitrogen content and increase the effective combustible component content in the gas, it causes the gas calorific value significantly increased and have solved the problem of environmental pollution and resource-wasting because the low calorific value gas was utilized effectively and released into the air.
